Welder Shortage Looms

According to the American Welding Society, more than 500,000 welders are employed in the United States. This is not enough to meet the increasing demands of industry. Also, more than half of the existing welder workforce is approaching retirement. By 2010, the AWS predicts demand for skilled welders will outstrip supply by 200,000.

Skilled Trades see welder shortage

Even as the economy slumps and unemployment rises, strong demand for welders has many welder jobs going unfilled. Manufacturers are scrambling to find enough skilled welders to plug current and future holes

TIG Welding

Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.

 

GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, GTAW is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques. A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated.[1]
