日本钛协会颁布了用于钛的TIG焊接的保护央具标准．近年来，随着钛加工业的兴旺发展，钛的焊接质量检验方法已经有JIS标准，寻求焊接保护夹具标准化的呼声越来越高。但是从前保护夹具作为焊接的诀窍，要进行个别设计与制作，其结构对外不公开，一直为焊接操作人员个人拥有。钛 Japan Titanium Association issued a standard for the protection of titanium TIG welding center. In recent years, with the rapid development of titanium processing industry, titanium welding quality inspection methods already have JIS standards, seeking to improve the standardization of welding protection fixture is getting louder and louder. However, in the past, as the know-how of protecting welding jigs, individual design and fabrication of jigs were required. The structure of the jigs was not disclosed to the outside world and was always owned by welding operators. titanium
