GTAW stands for gas tungsten arc welding, also known as TIG (tungsten inert gas) welding.
Like all welding, it is a technique used to join two metals. Just like you use nails to join two pieces of wood or mortar to hold bricks together.
With gas tungsten arc welding (GTAW), the welder must use both hands at the same time – one hand to hold the welding torch and another hand to fill the torch with wire. Coordination is required for this technique, but the welder enjoys more control over the finished product. If you were learning to drive a car, GTAW (TIG) would be like driving a stick shift.
GTAW (TIG) is great for welding with most metals: aluminum alloys, brass, copper, chromoly, steel, stainless steel – even exotic metals like magnesium and titanium. The process is not for welding with cast iron, however.
Because you can do GTAW (TIG) with so many types of metals, there are plenty of job opportunities. The welding process is used in many different industries including aerospace.
The aerospace industry includes design and manufacturing of commercial and military aircraft, rockets, missiles, spacecraft and more. Welders are especially important when it comes to engine repair.
