Things to Remember Before Buying Portable Welders

Friday, July 31st, 2009

Some of the things that you have to remember are type, voltage, thickness and cycle time.

Type: While buying a portable welder you have to thing about type. There are two types of welders like MIG and stick. Stick welders are little bit less expensive when compared to mig welders. It is a bit hard to use stick portable welder.

Voltage: Next important thing to remember before buying portable welder is the voltage. Welders can work with 110 or 220 volts. Welders that have higher voltage have more power.

Thickness: If you’re planning to work with thicker materials, then you have to choose portable welders that have 220 volts. 220 volts can be used for materials for any thickness.

Cycle time: Cycle time is nothing but the amount of time a welding operator can run the welder before it is turned off. Different portable welders have different cycle times. It would be better if you choose one that has the lowest time so that you don’t have to spend a lot of time waiting for the welder to cool off.

Who Should Work in Welding Profession?

Thursday, July 30th, 2009

Welding is nothing but joining of materials with or without the application of heat, filler material and pressure.

Who should go in for welding profession?

  • Who wants more job opportunities
  • Want high wages
  • Who loves challenges
  • Wants diversification in his work
  • Has a dream to travel in U.S. or abroad.

The basic skills required for welding are good eyesight, good eye-hand coordination, be able to work for longer period of time, have patience, manual dexterity etc.

There are many institutions who will teach you both latest and traditional welding skills. Other subjects like metallurgy and blueprint reading will also be taught. Much importance will be given to safety throughout the program.

There are nearly half million people in U.S. who are working as welders, cutters or welding machine operators. In that nearly three fourth work in manufacturing and service industry. If you also include boilermakers, ironworkers and pipe fitters the total would come to nearly 2 million or 10% of national workforce. Welders are needed in manufacturing sector like transportation equipment, industrial machinery and fabricated metal products.

All About Plasma Arc Welding

Wednesday, July 29th, 2009

Plasma Arc welding is a process which is very similar to TIG welding. It is a development of the TIG welding, which is designed to increase productivity.

Welding has been there for nearly thousand years and arc welding was developed over 100 years, but plasma arc welding came into existence since 1957.

Plasma is a mixture of positive ions, electrons and neutral gas molecules. Plasma arc welding is similar to other types of arc welding. But in case of plasma arc welding, electrode is inserted into a small nozzle. The major advantage of plasma arc method was the precision welds that could be made on thinner metals. Plasma Arc welding is the welding process utilizing heat generated by a constricted arc struck between a tungsten non-consumable electrode and either the work piece (transferred arc process) or water cooled constricting nozzle (non-transferred arc process).

Transferred arc process can be used for high speed welding and cutting of Ceramics, steels, Aluminum, alloys, copper alloys, Titanium alloys and Nickel alloys.

Plasma welding machines can be operated either manually or automatically. These produce straight and thin welds. Plasma arc welding remains one of the most economical and practical welding methods.

Benefits of Plasma arc welding are as follows:

  • High welding rate,
  • High penetrating capability and requires less operator skill.

Important Points on Training and Other Qualifications of Welding

Monday, July 27th, 2009

Many people want to become welders but are confused as where to start. If a person wants to become a welder he has to go in for a training that ranges from a few weeks of school or on-the-job training for low skilled positions to several years of combined school and on-the-job training for highly skilled jobs.

Where to take education and training: Welding training can be taken in high schools and in post secondary institutions like community colleges, private welding schools. Even U.S. Armed forces operate welding schools. Most of the employers hire workers who have already gone through the formal training. If a person does other courses like blueprint reading, shop mathematics, mechanical drawing, physics, chemistry and metallurgy or electricity, computers it can help him in this profession. A welding operator has to inspect welding equipments and welding process at regular intervals, so companies generally prefer workers who have a background in welding.

If an employer wants to hire a welder for certain positions which require specific skills he should have a certificate. American welding society certification courses are offered in many welding schools. For welding a worker should have good eyesight, manual dexterity and hand-eye coordination. They should be able to work for longer period of time.

Plasma Cutter Safety Tips

Thursday, July 23rd, 2009

Plasma cutting safety tips are different from welding. While working with plasma cutter keep all the flammable materials at least 35 feet away from the work space because sparks can ignite on flammable materials around your work space. Protect your eyes by wearing safety glasses and helmet. Use clothing made from tightly woven material such as leather, wool or industrial strength work pants. Wear high top leather boots to protect your feet. Do not keep matches or butane lighters in your pocket. Do not keep plasma cutter near flammable gasses, vapors, liquids, dust or in any location which may lead to explosion. To reduce the possibility of fire while working, always maintain a clean dry work area. Keep the torch tip of the plasma cutter pointed away from you at all times.

If you touch an equipment or metal part that is electrically hot it can lead to injury or death from the shock. A person can receive shock from a primary voltage or secondary voltage.

Welding Helmets Can Protect Your Eyes

Tuesday, July 21st, 2009

Welding helmets are user-friendly and offer more protection to eyes. For a layman, welding helmet is shielding your eyes from the bright lights of a welding arc. Lens used in welding helmet can protect the eyes from ultraviolet and infrared rays. An auto darkening lens will protect the welder from ultraviolet light whether the lens is clear or darkened. In auto darkening welding helmets, the lens will darken within 4/10ths of millisecond to filter out visible light. This is faster than your eyes have time to react to the light. If the lens is slower than 4/10ths of millisecond it is better not to purchase it.

An auto darkening helmet will protect your eyes from ultraviolet and infrared rays and also from 4/10ths of millisecond after the arc is lit. This helmet is better than old ones as you can see when the arc will shut off. The moment you stop welding, auto darkening lens will become clear. Now you can see your work properly without lifting the helmet. Another important function is to protect the face and eyes from flying objects. These
helmets are worth the extra cost.
