About Welders:

Wednesday, November 3rd, 2010

Welding helps in joining together two different metals. A welder has to go through apprenticeship before being qualified to be a full-fledged worker. A Welder can join metals such as steel, aluminum or copper together. They must maintain good dexterity and attention to detail as the job is relatively delicate.

The first gas welders began appearing in 1893, using different mediums to produce the best plasma discharge. The experimentation resulted in invention of the blowtorch, a device that allowed for a wider application through non-industrial needs.

A welder has to move through a series of stages in their career path. A welder’s apprenticeship is usually carried out through an accredited trade school. These programs last for two years, and give the beginning welder strong knowledge of the process, tools and materials used in welding. It also provides safety information that is imperative for a safe career.

Various dangers are associated with welding, some of which are also life threatening. Welders must wear leather gloves and long sleeves to lessen the impact of heat. Another problem is the bright light that is given off by the welder. It can cause damage to the cornea and ultimately lead to blindness.

Importance Of Qualification And Certification For A Welder:

Tuesday, October 19th, 2010

Certification means:

“Certification” for welders signifies to a certificate that mentions “I or we certify that” the mentioned welder or welding operator has successfully fulfilled a practical test of their abilities to execute a sound weld in accordance to some encoded standards.

Qualification means:

“Qualification” signifies that a welder or welding operator has successful met the necessities of an agreed standards and is qualified to carry out welds within the scope of the standard.

To become a certified welder then they are required to hold necessary skills so as to fabricate a sound weld that is visually agreeable and meets the requirements of testing. Do remember that to get a job or to keep up the job then operators have to perform a weld so as to show that they are capable enough to weld.

The procedure of testing engages welder to perform a weld that is then examined by an inspector, to make sure that the weld matches a particular code, standard, or written specification of welding process. Each examination has a different set of standards. The method of testing will involve visual inspection, and could entail either destructive or non-destructive testing.

All about ultrasonic welding:

Friday, October 15th, 2010

Ultrasonic welding is a welding technique in which the two pieces of plastic or metal joined together through high frequency acoustic vibrations. The acoustic energy is converted into heat energy by friction, and the parts are welded together in less than a second. When you see its history, it’s not invented so far before, it was invented during 1960’s and sonobond ultrasonic was the first ultrasonic welding machine to be awarded.

With the advent improvement in technology, the range of materials that can be joined together using this technique increases. At first only non-flexible plastics could be welded because their material properties allowed the efficient transmission of acoustic energy from part to part. Nowadays, less rigid plastics such as semi crystalline plastics can be welded because large amounts of acoustic energy can be applied to the welding zone. As the technology matures and becomes more versatile, it is likely to obsolete large classes of historical techniques for joining materials together.

The ultrasonic welding process is widely used in industries like electrical, computer, automotive, aerospace and medical.

Possible ways to weld a metal:

Friday, October 8th, 2010

The most effective means of welding a metal depend upon the types of metal as well as the skill level of the person doing the work. There are several types of welding that one can choose from. Most commonly, welding involves the joining of two materials. One way of welding a metal is known as wire feed welding or gas metal arc welding. It is often used for welding small items together, and is completed by using a welding gun or torch. Arc welding is another way of welding metal together also, known as shielded or manual metal arc welding; it uses an electrode that surges electricity into the metals to create a weld. A slightly less common way of welding metal is tig welding and this technique uses both a torch and a filler rod. Another method for welding metal is known as spot welding. This involves a large device with two arms, each of which holds one of the metal pieces that will be joined. Choosing the right kind of welding device and strategy will depend on the experience level of the weldor and the type of weld being made.

Tricks to weld the steel:

Wednesday, October 6th, 2010

Steel has been developed to resist a number of corrosive environments and it is a metal alloy that primarily consists of iron and has carbon content between 0.2 and 2.04 percent. It becomes harder and stronger, but more brittle as the carbon increases, and other elements also affect its physical properties. The composition of the steel must be determined before it can be welded effectively.

• Find out the weldability of the steel. This quality is inversely proportional to the steel’s ability to be hardened by heat, also known as harden ability. Generally, this means that steels with fewer alloying agents are more welds able.

• Compute the equivalent carbon content of different alloys of steel. This measure compares the properties of any steel alloy to those found in plain carbon steel. Carbon has the greatest effect on steel’s weld ability, followed by elements such as chromium and vanadium. Copper and nickel have the least effect.

• Make use of high strength, low-alloy steel specifically developed for welding applications, if possible. There is always a trade-off between strength and weldability.

• Austenitic grades of stainless steels are the most weldable, but they are particularly prone to distortion because of the high thermal expansion. Use an electrode that deposits a weld metal with a small amount of ferrite.
