MWA铸铁氩弧焊丝MAC CAST E405 TIG

Specially formulated general purpose high nickel wire for TIG welding cast iron requiring minimal dilution, smooth, dense, spatter free machinable deposits. Mac Cast E405 TIG provides dense deposits with high ductility on cast irons that are not severely contaminated.

特殊配制的Ni99高镍通用氩弧焊丝，用于焊接铸铁等材料。最小稀释，可产生光滑、无飞溅、致密的可加工焊缝。Mac Cast E405 TIG可在未遭受严重污染的铸铁上提供高延展性的致密熔覆层。

This grade may be used for:

1. l Joining and building up on cast irons, repairing thin section gray cast irons and for joining castings to steels;
2. l Welding of dissimilar metals (this alloy to stainless and carbon steels, to other nickel alloys, to copper and copper alloys);
3. l Welding of clad side of nickel-clad steel and surfacing/overlaying of steel;
4. l Welding of wrought and cast forms of commercially pure nickel alloy to itself;
5. l Use in high-grade plant/engineering (primarily for the petro-chemical industry).

该型焊丝可用于：

1. l 用于各种铸铁的连接和堆焊, 尤其适用于修复薄壁灰铸铁和将铸件连接到钢上；
2. l 异种金属的焊接（铸铁、不锈钢和碳钢、其他镍合金、铜和铜合金等）；
3. l 镀镍钢覆层侧的焊接和钢的堆焊；
4. l 锻造和铸造形式工业纯镍合金间焊接；
5. l 用于高等级工厂/工程（主要用于石油化工行业）。

This grade contains enough titanium to control weld-metal porosity on welding processes.

该型焊丝含有足够的钛来控制焊接过程中的焊缝金属孔隙率。

典型应用：发动机缸体、缸盖、泵壳、齿轮箱壳体、泵阀座以及机器底座的断裂和裂纹修复；当要求焊后高可加工性时修补孔洞和对磨损或缺失部分堆焊的理想选择，比如铸造缺陷的修复。
