Applications应用

Joining and overlay welding or copper zinc alloys, low copper materials, also for an excellent wear resisting overlay welding on low and unalloyed steel as well as cast iron. For MIG overlay welding of large work pieces preheating is recommended. For multilayer welding on steels, pulsed arc welding is recommended. Appropriate for MIG brazing of zinc coated sheets.

适用于铜锌合金和低铜合金的接合焊和加层焊，同时加层焊对于低合金和非合金钢和铸铁具有良好的抗磨损性。用于大焊件的MIG加层焊时建议预热。在多层焊接钢材时，建议便用脉冲电弧焊，特别适合于镀锌铁皮的MIG焊接
