大中型混流式转轮的焊接工艺

The Welding Process of Heavy and Medium Mixed Flow Type Runner

介绍了采用国产焊丝、混合气体保护焊焊接0Cr13N i5Mo系列材质的大中型混流式水轮机转轮的焊接工艺及实施情况。与手工电弧焊相比,提高工效两倍以上,并节约资金和能源。

This article has introduce the welding process of 0Cr1 3Ni5Mo series heavy and medium mixed flow type turbine runner which adopts home-made welding wire and the mixed gas arc welding, as well as its operation condition. Comparing with the manual metal arc welding, the mixed gas arc welding can increase the work efficiency more than twice, and also can economize on money and energy sources.
