引言近25年来,自动焊和半自动焊方法的应用已愈加广泛。在这段时期,新设备、新焊条和新工艺的研究蓬勃发展。这些成就及即将出现的其他成就都将进一步扩大焊接方法的应用范围。现在有许多采用自动焊的工厂使相当复杂焊接件的生产实现了高度机械化。在这种场合下,为保证焊接适当,焊工的唯一作用就是通过操作过程几乎连续的监视来进行质量控制。如果自动焊使用得当,其焊接质量将比手工焊或半自动焊更高,而且更加便宜。主要原
Introduction The application of automatic and semi-automatic welding methods has become more widespread in recent 25 years. During this period, research into new equipment, new welding electrodes and new processes has been booming. These achievements and forthcoming other achievements will further expand the scope of application of welding methods. There are many factories that use automatic welding to make the production of fairly complicated welds highly mechanized. In this case, to ensure proper welding, the welder’s sole role is to provide quality control through almost continuous monitoring of the process. If automatic welding is used properly, its welding quality will be higher than that of manual or semi-automatic welding, and cheaper. The main original
