铜和铜合金已被广泛地应用于各个工业部门中。铜是导电及导热最好的电气材料,而铜合金作为结构材料,在化工容器、酿造设备、给水管、锅炉及船舶用的部件上获得了广泛地应用。长期以来,铜和铜合金的焊接主要是气焊及碳极电弧焊,但焊缝的机械性能不高,并非都能满足技术要求。后来,采用了金属极手工电弧焊、情性气体保护焊及焊剂层下熔化极自动焊。最近又发展了等离子焊等焊接方法,从而解决了或正在解决焊接中的各
Copper and copper alloys have been widely used in various industrial sectors. Copper is the best electrical material for conducting and conducting heat. Copper alloy, as a structural material, is widely used in chemical containers, brewing equipment, water supply pipes, boilers and marine components. For a long time, copper and copper alloy welding is mainly gas welding and carbon arc welding, but the mechanical properties of the weld is not high, not all meet the technical requirements. Later, using a metal hand arc welding, emotional gas shielded welding and flux layer under the automatic welding. Recently, the welding methods such as plasma welding have been developed to solve or solve the problem of welding
