紫铜零件的焊接,根据技术要求不同,可采用碳弧焊、手工氮弧焊或者使用铜芯焊条的手工电弧焊。而对于壁厚为0.8～2毫米的紫铜管,通常则采用气焊。但是,气焊的约束条件比较多,比如硼砂、铜条、电石、氧气,缺一不可。为此,我厂采用了低碳钢焊条焊接薄壁紫铜管。经三年的生产 Copper parts welding, according to different technical requirements, can be carbon arc welding, manual nitrogen arc welding or the use of copper electrode manual arc welding. For the copper wall thickness of 0.8 to 2 mm, usually using gas welding. However, the gas welding constraints are more, such as borax, copper, calcium carbide, oxygen, are indispensable. To this end, I plant the use of low carbon steel welding thin-walled copper tube. After three years of production
