What is called as welder and what are the different types of welding machines available?

Welder is a machine that does the welding process in a most efficient way and most of the people get confused with the term welder and weldor. As said above, welder is a welding machine and the weldor is the people who do this welding process. The different types of welding machines available are tig welder, arc welder, mig welding machine, plasma cutters and etc are the different types of welding machines available.

Why plasma cutter is called as the scientific welding machine?

Plasma cutting machine is called as the scientific welding machine because in this process it uses the gas called plasma and it is a state of matter that is used in science. It does the process in a accurate and faster way and performs the dual role and act as both plasma cutting and arc gouging machine.

When was the welding process formed?

This process was formed before several millennia and the earliest examples are Bronze Age and Iron Age and middle age is the period that brought some advances in welding. In the year 1540, the vannoccio published the descriptions that include forge operation. In 1802, the Russian scientist proposed the practical applications of electric arc that also includes welding. In world war, the welding processes were widely used and 1920 was the year in which some major advances in welding technology and machines were used.

Who uses the welding processes the most?

As stated in the starting of the article, the manufacturing industries use this process the most and industries like, ship building, aircraft, motor manufacturing, automotive industries, electronic industries and in construction industries the welding process is widely used.

Where to get efficient welders?

Search in internet, you get a variety of manufactures who provide these welding machines in a quality and efficient way. Search for the best products in the market and also, before buying those machines, make sure that you get the machines that are quality and that have efficient duty cycle.

Developing Essential Study Skills That Will Help You Reach Your Goal

When you are a student, you find ways in order to cope with a lot of stress and pressure in school. Academics are very tough especially if you are faced with a lot of nerve wracking and brain cracking puzzles and things to memorize and solve. I know because I have also been a student once and it takes a lot of courage to be able to finish what you have started. There is no wonder why many kids drop out from school. They just could not take the world of education. As for me, in order to pass your subjects you have got to develop essential study skills but that is not all easy.

Who said being a student is easy? It is not. You also face a lot of problems in school-emotionally and mentally. You need supervision from other people so that you will be reminded of the things that you must do and to keep you in the right track. There should also be balance both from studies and extracurricular activities. It is not healthy that you only focus on one thing or you just spend most of your time perhaps just studying or just having fun to the point that you compromise the other. I have see some students who are just study all the time and they do not go out and have fun with their friends, they end up depressed. Or there are also those who prioritize their social life more and so they end up failing their subjects.

But how do you develop essential study skills? Personally, I think you do not need a tutor or a a book that can give you tips on what you should do to ace the test. Mindset is one very important thing that you must develop. As long as your mind is not fixed on a certain goal or priority then the steps that you will be taking next would be useless. Ask yourself what your aim is whether you just want a passing mark or you want to be in the honor roll. Then by the time you already know what, you make the necessary steps needed like developing good study habits. Be organized. Be dedicated. Be patient. Be motivated. These are the things that you should always put in mind.

It is always up to you to make things happen. Your teacher is just a medium for you to understand your lessons. In order for you to become a good student, you have to develop essential study skills. These skills will help you reach your goal. But it does not happen overnight s you really have to be patient about it.

The Importance of time management for students: Take control of student study skills and academic time management.

Article by Andrew Chambers

Are you a high school or a college student? Are you burnt out or stressed out? Do you often feel run down and tired? Is your life spinning out of control in a disturbing way? Do you have too many priorities or pressures? Study skills time management is an essential skill you need to develop to take charge of your college life.

Student days are considered to be one of the busiest moments in our lives. Recitations, assignments, projects, and exams are the things that make students feel exhausted. Aside from that, there are work commitments and social events that you would like to attend.

All of these competing demands influence time management. If the students does not have any idea about budgeting time and keeping a schedule you can easily spin out of control, get stressed out and fall into bad practices such as cramming or doing ‘all nighters’. This gives rise to the importance of time management for students.

With proper study skills time management and prudent planning, it is possible to balance student commitments with other life commitments. Taking a proper control of your time is essential to realize your goals and objectives.

Here are some positive benefits to learning student time management skills.

* Academic time management can help the student better learn new material. By taking a steady and consistent approach you absorb the material in small chunks so that you are better prepared when exam time comes around..

* Student time management also helps you for class preparation. Often concepts that are introduced in a previous class need to be properly understood in order to build a new understanding of concepts that are introduced. By allocating time to study material as you learn you can improve your class absorption rate and efficiency.

* Student time management also ensures that you structure your commitments by priority. By properly scheduling your requirements you avoid running into competing demands. This can happen if you are disorganized.

* Time management also allows you to set aside time for leisure and social events. If you have your priorities attended to you won’t find yourself in the position of having to skip social events that you have been looking forward to.

* Student time management is a proactive approach to making best use of all your available time. By knowing when you have breaks between class you can set aside that time to attend to study commitments. By setting up a schedule this way you get to take control of your day to day student requirements. This can help you avoid falling into the trap of ‘goofing off’ between classes and frees up your time at night for other activities.

Getting started on student time management is often the most difficult task. Taking the time to learn this skill will pay dividends throughout your college life and will also be a valuable skill you can take forward for managing your life. Be prepared and learn what you need to know early in life to make the best use of your time.

4 Ways to Get Better Marks Without Trying Harder

Article by Geoff R.

Have you ever looked at that top-performing student in your class and wondered, “How on earth do they do that?”. Well to be honest, there is no quick fix in terms of increasing your average in high school or college. High-level study habit tweaking in particular takes a lot of work, and sometimes it isn’t even worth it. That said, there are a few easy things that you can do right now or within the next day that will help you increase your average.

1. Turn off MSN and Facebook while studying. You know how sometimes when you are playing a sport or working, you enter “the zone”? The Zone is a zen-like state where you are completely focused on the task at hand, and you are performing it at peak effectiveness. Aside from the fact that multi-tasking is inefficient, if you have MSN open while you are doing your work, you will never be able to get into the zone. And trust me, you WANT to get into the zone.

2. Twist assignment topics to reflect your interests. Say you are a sports fanatic, and you get an assignment on Women throughout the Century in history class. Ask the professor if you can do your report on women athletes throughout the century, or something similar. Make sure you ask your professor first, because this isn’t always an option.

3. Set precise academic goals for yourself. If you really want to change your grades, you need to set specific goals. “study harder, get better grades” is not good enough. Set goals like “Get over 80% on the final exam” or “Increase my average by 3% each semester”. After you set your academic goals, post them on your fridge, by your bed, and anywhere else that you will see them often.

4. Write down all the things that are helping your marks, and all the things that are hurting them. Focus on increasing the good habits and decreasing the bad. If you can successfully change your habits, your marks will surely follow.

The Best Assembly Techniques

Welding technology – In addition to the assembly techniques described in article 7 of
this series, many different welding methods can be used to join plastic parts. To ensure
low-cost, functionally efficient designs, it is necessary to select a suitable welding
method and give careful thought to the required joint geometry at an early stage in the
design process.

Welded joints are assemblies for permanently connecting plastics parts without additional assembly elements. The choice of welding method depends on several criteria: the geometry of the moulded part and on the materials used, on cost-effectiveness, suitability for integration into the overall production cycle and the mechanical and aesthetic quality requirements for the assembly zone.

Different welding methods

There are many different, cost-effective welding methods suitable for industrial mass production. The methods most frequently used for plastics engineering components are:
- hot-tool welding
- spin welding
- vibration welding

]]>

- ultrasonic welding.
Other methods worth mentioning include:
- high-frequency welding
- induction welding
- hot-gas welding.
New methods are also being developed (e.g. laser welding), but these are not yet widely used in industry.
In all these methods, the assembly operation is carried out by applying heat (melting the surfaces to be joined) and pressure. Heat can be generated directly by contact or radiation, or indirectly by internal or external friction, or by electrical effects.

Choosing the right method

To achieve good, reproducible weld quality, it is necessary to choose a suitable welding method, optimize welding parameters and ensure that the parts to be assembled are correctly designed for the welding method being used. Welding machinery manufacturers supply not only standard equipment but also various special welding units to cater for a wide variety of welding tasks. Before deciding on a welding method of the plastic molding, it is advisable to consult the machinery manufacturers or resin suppliers.
Different welding properties

Theoretically, all thermoplastics are weldable, but the welding behaviour of plastics differs considerably in some cases. Amorphous and semi-crystalline polymers cannot be welded together. Plastics that absorb water (e.g. nylon) need to be pre-dried, since moisture leads to poor-quality welds. For best results, nylon parts should either be welded immediately after injection-moulding or kept in a dry state before welding. Resin additives such as glass fibres and stabilizers can also influence welding results. Welded assemblies of unreinforced plastics can attain weld factors close to the strength of the parent material, given suitable process parameters and part design. With glass-fibre-reinforced plastics, loss of strength due to fibre separation or reorientation in the welding zone must be taken into account.

About welding jobs and salary

Article by John Peter

Before analyzing the existing wage structure of people welding jobs or assessing what salary the welding jobs merit, it will be sane to first study the job profile of people who are professional welding operators.

Simply stated, welding is the process of heating and melting metal parts to permanently join them. Welding finds wide applications in many industries including automobiles, airplanes, ships, and fabrication of sheet-metal products. Welding also becomes necessary when constructing bridges and building products. It is also the part of a welder’s job to cut metal into pieces or to cut structures as per design and to discarded unwanted metal.

Welders are mostly classified as skilled workmen as welding jobs do call for some special training and expertise. Professionally qualified and experienced welders work from blueprints and to other pre-determined specifications. They are fully aware of the welding properties of various kinds of metals and the varying techniques needed to weld them.

In fact, with the availability of advanced technologies, welders even rely on computers and robots to weld metal pieces to precision. Less skilled welders work on projects that do not call for advanced skills like common types of fabrication and do repetitive work in manufacturing units that calls for no special knowledge of welding properties.

There are numerous methods of welding that use either electricity or various gasses to generate the required levels of heat to bond metals. Arc welding, which can be done either manually or with the aid of machine, is the most common method. Another form of welding, that is equally common, is the use of gas. Though many types of gases are deployed, the common one is an acetylene and oxygen torch.

As regards the educational qualifications required to pursue a career in welding, a high school diploma with mathematics, physics, mechanical drawing and principles of electricity will be useful – though this qualification can not be deemed essential. It can also be said that a basic knowledge of computer and functioning of robots will be helpful for advancing in one’s career as a welder.

Industrial training institutes, vocational trade schools, and some community colleges offer training programs for welders, and some manufacturing companies also provide in-house apprenticeship for welders. Apart from the educational qualifications and professional training, an aspiring welder should possess sound health, manual dexterity, sharp eyesight, and good hand-eye coordination.

As regards wages, the currently prevailing standard norms are:* Hourly Rate .40 – .41 * Overtime .79 – .26

There are employers who also offer: * Bonus 8.73 – ,511 * Profit Sharing 6.27 – ,057

There could also be earnings in the form of tips, commissions and cash incentives. Of courses the salary/wages will vary depending on the location and the size of the employer.

Underwater welders and those who well-qualified and adequately experienced in complicated forms of welding and those who inspect welds, or teach welding earn more money than people who do routine welding jobs.

Construction companies and manufacturing plants offer ample employment opportunities for welders. Local union offices or state employment agencies offer guidance about training and job openings for welders. Newspaper classified ads and Internet job banks are also excellent sources of information for people wishing to embark on a welding career.

Improve time management with speed reading techniques

Article by santosh

In present times students either of schools or colleges are the busiest ones and have enormous activities to do along with their studies in limited time. Students have to prepare huge amount of syllabus for their frequently held examinations and thus they don’t get enough time to prepare the whole syllabus in proper details. For this purpose they have to adopt memory skills and speed reading techniques for a faster reading and learning process. These techniques comprise tools and strategies that have been developed after due consideration and practical uses and has proved useful in completing the syllabus in lesser time and yet in an effective way. These skills are focused in helping students to learn any particular lesson or piece of information in a speedy way without missing the important part of it.There are many methods that have been developed to read faster amongst which most popular ones are chunking, skimming and sub-vocalization. For the vast syllabus in front of you, it’s not possible to learn everything in it and so chunking helps in briefing it down. Chunking is basically the process of grouping verbal and written information efficiently to make it more logical, organized and consistent. It works on the principle that organized information is easier to learn and understand than a shattered one. Another speed reading technique is skimming which is used to quickly identify the main ideas of a text just like scanning. It consist speed that is three to four times faster than normal reading facilitated by moving the eyes down the page seeking only specific words and phrases. Knowing how to speed read can really help you in completing your syllabus on time along with cutting down the burden. You can also try sub-vocalizing which is a method of silently pronouncing the word while reading thus allowing the reader to imagine the sound of the word as it is read. It helps the mind to access meanings to enable it to comprehend and remember what is read. Most of the speed readers use a variety of methods to increase their speed and comprehension level as it is hard to read every word present on the page. Reading any text works half way through learning it as our minds can easily translate and mold words as per its convenience. This helps in time management for studies in our busy schedules and limited time period before exams.

Overview of Mechanical Engineering PE Exam and HVAC and Refrigeration Study Tips

The professional engineering license is one of the most important steps in an engineer’s career.  It allows the individual to legally practice engineering in the state of licensure.  This credential can also help the engineer to obtain higher compensation and provide the first step in developing a credible reputation.  But in order to obtain this license, the engineer must first meet the qualifications as required by the state of wanted licensure, including working a minimum amount of years under a registered professional engineer.  These engineers must serve as references on the application.  The state licensing board for the exact amount of years and references required should be contacted.  The engineer must also have passed the Fundamentals of Engineering exam.  Finally, the engineer must pass the Professional Engineering or PE Exam in his or her discipline.

The Mechanical PE Exam consists of an AM or breadth portion (4 hours) which covers HVAC and refrigeration; Mechanical Systems and Materials; and Thermal and Fluids Systems.  The PM or depth portion (4 hours) covers the engineers specialty.

]]>

HVAC & Refrigeration Study Tips

The first step in studying for the HVAC & Refrigeration afternoon module of the mechanical PE exam is to obtain the appropriate references.  These references are the most commonly used references by a working HVAC & Refrigeration engineer.  For some these may be old college textbooks and for others they may be just the working code books.  I recommend the following references:  ASHRAE Fundamentals, ASHRAE HVAC Systems AND Equipment, ASHRAE HVAC Applications and ASHRAE Refrigeration, a Mechanical Reference Manual, appropriate ASHRAE codes (62, 90.1, 15, etc.) and NFPA 90A.  Working professional engineers will most likely have more than these references, but for the PE exam I feel these are the minimum references.

The second step is to obtain the necessary minimum skills and knowledge of a professional engineer.  The hardest part of this step is determining these minimum skills.  One way to accomplish this is to think like the test-creator.  If I were a test-creator what would I qualify as the minimum skills of a professional engineer and what can I test?  I feel that these requirements all lead back to the fundamentals of engineering in practice.  The term “In practice” excludes the science behind the actual skill and focuses on the actual doing and solving of a problem.  The best way to explain the difference between a skill and the science behind it, is with examples:

Navigating a refrigeration diagram and using it to find the capacity of a chiller operating at certain parameters, not explaining the theory behind the diagram.

Navigating a psychrometric chart and using it to solve air mixture problems, not explaining the theory behind the creation of the chart.

Navigating the steam tables and using it to solve for the amount of super heat, not explaining the equations used to create the tables.

Knowing your references.  Several problems may be as simple as finding the appropriate reference and looking up the solution.  In the practice of engineering, many problems are solved by researching the applicable code or a reputable reference.

Goggles Provide a Variety of Eye Protection

With today’s medical science and technology, physicians and scientists can do remarkable things that were unknown only a decade ago; organ transplants, cloning, microsurgery, etc. But still, we have only one pair of eyes. Many of us enjoy activities or occupations that can cause serious injury and even blindness if we treat our eyes carelessly. This is where a good set of goggles can save our eyes! For example, when you enroll in a welding school, the first thing you’ll learn is that safety goggles are essential to protect your eyes from sparks and gasses. Military and law enforcement personnel learn the importance of night vision goggles to conduct reconnaissance missions. In fact, sunglasses-type goggles are currently in use by the US armed forces in Iraq to protect their eyes from both blowing sand and the glare of desert sands.

Sports enthusiasts of all kinds know the importance of a well-made set of goggles from manufacturers like Smith, Scott and Oakley. If you ride motorcycles, for example, goggles protect your eyes from debris and insects that, at high speeds, become projectiles that can cause permanent eye damage. Though many cyclists prefer the feeling of freedom of the open road, there is no doubt that goggles and helmets save lives!

]]>

Frequent swimmers, especially professional athletes, use water-resistant goggles to prevent damage to their eyes from chlorine in swimming pools and ocean salt water. Long-distance swimmers who swim the length of the Great Lakes or the English Channel regard goggles as a life-saving necessity!

Winter sports enthusiasts know just how essential goggles are to protect their eyes and increase their chances of obtaining championship status among their peers. Ski and snowboard goggles protect these athletes’ eyes from both blowing, freezing ice and snow as well as reducing glare from the stark white snow. The sports of extreme downhill skiing or snowboarding are extremely dangerous without goggles as essential eye protection.

Are you a marksman who enjoys competition shooting or a hunter of large game? You’ll need to add a quality set of goggles to not only keep your vision clear for an accurate aim, but also to protect your eyes from stray high-velocity bullet casings that can cause permanent blindness. Bullet casings are very hot from the gunpowder that fires the ammunition round; a large, hot casing can cause irreparable damage to the cornea and the optic nerve.

Paintball competitions have become enormously popular in the past few years; it’s fun, exciting, and unfortunately, potentially extremely dangerous without protective eyewear. Military and law enforcement personnel have long used paintball games to determine the accuracy of their abilities to subdue an enemy with one shot. Without the protection of snug-fitting goggles, a paintball to the eye, traveling at about 40 mph, can literally pulverize a human eye in seconds.

It’s possible to enjoy the sport and occupation that suits your interest without taking unnecessary risks to your ocular health. Goggles, depending upon their intended use, are relatively inexpensive compared to your welding torch or snowboard. Why assume the risk of a serious injury that is entirely preventable?
