Product Introduction:
Nickel, cobalt and high nickel alloy ellipsoidal head is mainly fabricated with nickel, cobalt and high nickel alloy material.
Notice Of Production:
When it use shielded metal arc welding, since the welding rod alloy element is much, also require to prevent heat cracking, normally the nickel base alloy covering type is alkaline covering, adopts direct current reverse polarity. To prevent alloy element burning loss and control line energy, it requires to adopt small regulation while welds, compared with same specification stainless welding rod, the current can low 20-30%. because the liquid metal mobility is bad, to prevent poor fusion,air hole and other damages, normally it requires appropriate swing during welding process, but shall not be too big. When the welding joint connector starts arc again, shall adopt reverse arc technology, in favor of adjusting the welding joint at the connector part smoothly,and prevent air hole occur,adopt reverse arc suppression, fill in the crater, prevent crater crack, it makes polishing to the crater in necessary.
