KEYHOLE WELDING: SAVINGS FOR STAINLESS

摘要

Researchers from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Cooperative Research Centre for Welded Structures (CRC-WS) have developed a welding process for stainless steels and other corrosion-resistant metals that is significantly faster, cheaper and easier than current practices. The patented process is an elaboration of standard gas-tungsten arc welding (GTAW), and uses a specially designed torch that establishes and maintains a 'keyhole' at the joint.
