history

The process by which gas was used along with an electrical current to create an arc across two materials was first introduced in the 1930s (W. Alexis,). World War I ended and they needed a better way to make more weapons and repair different items. So a company made The GTAW welding process which was first developed in Southern California. Russell Meredith of Northrop Aircraft Corporation (TIG) created the Heliarc process. It was developed in 1944 (A Short ). By the time World War II had started, they had the Heliarc process to make aircrafts, planes, and repair weapons Heliarc is referred to by this name because the welding process requires the presence of two substances. These substances are helium, an inert gas that is used for the shielding of the weld, and an arc that is generated through the implementation of a tungsten electrode. The electrode receives a constant power signal from the welding machine (W. Alexis,). The Union Carbide Corporation Linde Division bought the rights to the Heliarc welding patent and began to develop different torch designs, consumables parts of the torch that is used up quickly like tungsten, different back caps, collets, and collet bodies, and that is all spare parts for the Heliarc torches as well (TIG ). Linde then marketed the process and the torches under the “Heliarc” brand name (TIG ). They then found a gas that was cheaper and could weld more fluently and better.
