摘要
为解决不锈钢焊接时的背面氧化问题 ,引进了日本的TGF系列背面自保护焊丝 ,焊接工艺试验及炼油装置不锈钢管线的焊接使用表明 ,其焊缝质量良好 ,背面药皮剥脱容易 ,尤其适用于不锈钢钨极氩弧焊 (TIG)
In order to avoid the stainless steel back oxidized,Japan TGF serial back self-protection electrode-wire was imported.It is illustrated that welding quality is good and back slag peel off easily through welding process test & practice use to stainless steel pipes on refinery.It is especially suitable for TIG back run welding.
