Keyhole gas tungsten arc welding joins high-cost metal parts.(Welding/Joining)

An automated keyhole gas tungsten arc welding (GTAW) process for joining stainless steel, titanium, and other high-cost materials has reportedly been developed jointly by CSIRO Manufacturing Science & Technology and the Cooperative Research Centre for Materials Welding and Joining, both of Australia. Designed for conventional high-current GTAW equipment, this technology is said to able to replace gas metal arc, submerged arc, or plasma arc welding for joining plates or pipes. Joints need only be prepared with squared edges, and butted together while the welding is completed ...
