Instructions |
||||||||||
1.The Electrodes must be baked under 250℃ for an hour before Welding. |
||||||||||
2.Worn high manganese steel surfacing weldment, should be eradicated the beforehand fatigue layer or by water in toughening processing, or render by chromium manganese steel electrode (such as CHR276) |
||||||||||
3.When surfacing welding,smoking is big, we should strengthen ventilating, welder should stood in Internet position to operate. |
