MWA鑄鐵氬弧焊絲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高鎳通用氬弧焊絲，用于焊接鑄鐵等材料。最小稀釋，可產(chǎn)生光滑、無(wú)飛濺、致密的可加工焊縫。Mac Cast E405 TIG可在未遭受?chē)?yán)重污染的鑄鐵上提供高延展性的致密熔覆層。

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).

該型焊絲可用于：

1. l 用于各種鑄鐵的連接和堆焊, 尤其適用于修復(fù)薄壁灰鑄鐵和將鑄件連接到鋼上；
2. l?異種金屬的焊接（鑄鐵、不銹鋼和碳鋼、其他鎳合金、銅和銅合金等）；
3. l?鍍鎳鋼覆層側(cè)的焊接和鋼的堆焊；
4. l?鍛造和鑄造形式工業(yè)純鎳合金間焊接；
5. l 用于高等級(jí)工廠/工程（主要用于石油化工行業(yè)）。

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

該型焊絲含有足夠的鈦來(lái)控制焊接過(guò)程中的焊縫金屬孔隙率。

典型應(yīng)用：發(fā)動(dòng)機(jī)缸體、缸蓋、泵殼、齒輪箱殼體、泵閥座以及機(jī)器底座的斷裂和裂紋修復(fù)；當(dāng)要求焊后高可加工性時(shí)修補(bǔ)孔洞和對(duì)磨損或缺失部分堆焊的理想選擇，比如鑄造缺陷的修復(fù)。
