铜及铜合金焊丝
1.1 使用说明
铜及铜合金焊丝常用于焊接铜及铜合金,其中黄铜焊丝也广泛用于钎焊碳钢、铸铁及硬质合金刀具等。
适用于气体火焰焊、氩弧焊和碳弧焊等工艺方法。
氩弧焊是保证铜及铜合金焊接质量的有效方法,既能有性能良好的焊缝,又可减少焊件变形,但填充金属要根据母材选定。
各种焊接方法焊接前,要求对母材进行清除油脂、氧化物等处理。
copper and copper alloy solder wire
1.1 Guideline
Copper and copper alloy solder wire can used for copper and copper alloy, the brass solder wire used for carbon steel, cast iron, and carbide tools.
Used for flame brazing, argon arc welding and carbon arc welding.
Argon arc welding is a effective method to keep good quality for copper and copper alloy, not only we can get high performance weld joint but also to reduce deformation, but choose filler metal should according to the matrix.
The matrix should be clean up before welding.
