High-efficiency TIG Arc Welding by Laser Activation (LA-TIG Process) (Report 1)

- LA-TIG Weldability on Type 304 Stainless steel -

Abstract

In order to increase the penetration of TIG Arc Weld, laser activating process was devised. As the result of the welding with the devised process, deeper penetration weld, depth > 5 mm, aspect ratio > 0.7 under the condition of I=150A, v=2 mm/s for example, was obtained.
