磁控旋转电弧焊(简称旋弧焊),具有节约电能、不需填充材料、焊接生产率高、接头成型美观、质量好、易于实现自动控制、改善劳动条件等优点。因此,近年来这种焊接方法已经发展到可以提供工业应用的阶段。它不仅用于管道工程,而且还用于车辆、农机及一般机械制造等。近年来,许多工业发达的国家都在研究和发展这种新工艺,并在实际生产中扩大它的应用范围。国内也正在研究这种新工艺,并取得了一定的进展。我院已研制了一台YHX—1型旋弧焊机,并采用不同的气体作保护介质,焊接了几种钢管。通过一系列的工艺试验,不仅对不同保护气
Magnetron rotary arc welding (referred to as arc welding), with energy saving, without filling material, high welding productivity, beautiful appearance fittings, good quality, easy to achieve automatic control, improve working conditions and so on. Therefore, in recent years, this welding method has been developed to provide industrial applications at the stage. It is not only used for plumbing, but also used in vehicles, agricultural machinery and general machinery manufacturing. In recent years, many industrialized countries are studying and developing this new technology and expanding its scope of application in actual production. Domestic is also studying this new technology, and made some progress. Our hospital has developed a YHX-1-type spin-arc welder, and the use of different gases for protective media, welding several kinds of steel. Through a series of process tests, not only for different shielding gas
