Gas Tungsten Arc Welding Electrodes

Abstract

When inert gas shielded arc welding was introduced nearly 60 years ago few would have imagined the impact the process, and in particular the non-consumable electrode version, would have on the fabrication industry world-wide. The tungsten arc welding concept was rapidly adopted from the 1950s and made a pivotal contribution to the development of nuclear, chemical and aerospace technology. It is arguably now established as the most versatile technique for producing fusion welds to the highest quality standards.
