銅及銅合金焊絲
1.1 使用說明
銅及銅合金焊絲常用於焊接銅及銅合金
,其中黃銅焊絲也廣泛用於釺焊碳鋼
、鑄鐵及硬質合金刀具等
。
適用於氣體火焰焊
、氬弧焊和碳弧焊等工藝方法
。
氬弧焊是保證銅及銅合金焊接質量的有效方法
,既能有性能良好的焊縫
,又可減少焊件變形
,但填充金屬要根據母材選定
。
各種焊接方法焊接前
,要求對母材進行清除油脂
、氧化物等處理
。
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.
