上海斯米克铜焊丝 S229钎焊铜合金焊丝 Cu55 Ni6 Mn4斯米克焊丝上海斯米克S229铜焊丝 Cu55 Ni6 Mn4钎焊铜合金焊丝1.氩弧焊时建议用大流量、低流速的气流，以保证焊接熔池得到良好的保护。 2.薄板采用I型坡口；较厚的板采用V型或X型坡口，需加衬垫。 3.好采用平焊位置焊接。在有脉冲电弧焊设备和焊工操作技术良好的情况下，也可进行其他位置焊接。 4.不推荐把这种焊丝用于气焊，因为在焊接熔池中会有铝的氧化物存在，影响焊缝质量。 5.将焊接部位的锈层、湿气、油污、灰尘等确实除净。铜及铜合金焊丝的用途有三种：首先是焊接铜及铜合金，用于铜及铜合金连接；其次由于具有良好的耐蚀性和耐磨性，常用于堆焊耐金属间摩擦的部件（如轴瓦、低压阀门密封面）和耐海水腐蚀工件（如螺旋桨）等；此外，更广泛的是用于钎焊钢、硬质合金工具等。铜及铜合金焊丝可用熔化极氩弧焊（MIG焊）、钨极氩弧焊（TIG 焊）、气焊及等离子弧焊等方法施焊。钨极氩弧焊（TIG焊）通常采用直流正接方法，熔化极氩弧焊（MIG 焊）通常采用直流反接方法。
