本文件规定了钛和钛合金熔焊用实心焊丝、实心焊丝和焊条的分类要求。根据它们的化学成分进行分类。 金属惰性气体（MIG）焊接用实心焊丝的成分与钨极惰性气体（TIG）电弧焊、等离子弧焊、激光束焊接和其他熔焊工艺用实心焊丝、实心焊丝和焊条的成分相同。

This document specifies requirements for the classification of solid wire electrodes, solid wires and rods for fusion welding of titanium and titanium alloys. The classification is based on their chemical composition. The compositions of solid wire electrodes for metal inert gas (MIG) welding are the same as solid wire electrodes, solid wires and rods for tungsten inert gas (TIG) arc welding, plasma arc welding, laser beam welding, and other fusion welding processes.
