filler wire

基本解释

The submerged-arc welding using Chinese filler wire is reliable in construction of CF62 steel tank.
证实用国产焊丝的埋弧自动焊方法可用于国产CF62钢的大型原油贮罐的建设。
Because TIG welded joints without filler wire always hold low strength and poor formation, tungsten inert gas welding process with filler wire is inevitable.
由于镁合金不填丝的TIG焊接接头强度低，焊缝表面成型不好，所以，镁合金的填丝TIG焊接方法不可避免。
The results show that, the filler wire can eliminate the subside and undercut of butt joints which are inevitable in the laser welding aluminum alloy without filler wire.
结果表明，填充焊丝可以消除铝合金激光自熔焊时的凹陷、咬边等宏观缺陷；
