MONEL? 187焊條采用直流正接的方式AWS A5.6 ECuNi

MONEL^? 187焊條

MONEL 187 焊條可應用于鍛造或鑄造70/30、80/20或90/10銅鎳合金的手工電弧焊中。與被焊母材一樣，這種焊接材料在海水中也有優異的抗污損和腐蝕的能力，因此也可用于海洋作業及脫鹽淡化的場合。這種焊條可以用于異種材料的焊接，如銅鎳合金與MONEL400合金或與NICKLE 200的焊接。

    187焊條應采用直流正接的方式，并適用于全位置焊接。

MONEL ? 187 electrode

The MONEL 187 welding rod can be used in the manual arc welding of forging or casting 70/30, 80/20 or 90/10 copper and nickel alloys. As well as being welded, this welding material also has excellent anti-fouling and corrosion resistance in seawater, so it can also be used in Marine operations and desalination. This electrode can be used for welding of heterogeneous materials such as copper nickel alloy and MONEL400 alloy or welding with NICKLE 200.

The welding rod shall be directly connected by dc and shall be applicable to all position welding.
