MWA特种钢氩弧焊丝MAC TRODE E66 TIG|AWS A5.9 ER312
This grade may be essentially used for:
l welding of stainless steels with similar chemical composition;
l welding of dissimilar steels such as medium and high carbon steels to stainless steel;
l welding and facing of difficult-to-weld steels and unknown steels;
l buffering of layers on tooling prior to surfacing;
l wear facing, where resistance to severe impact is required.
该款焊丝可用于：
l 具有类似化学成分的不锈钢焊接；
l 碳钢与不锈钢等异种焊接；
l 难焊钢、未知钢的连接和堆焊；
l 工具堆焊前的缓冲层；
l 要求耐严重冲击的耐磨堆焊。
