焊接是现代机械制造业中一种必要的工艺方法,同时在汽车制造中得到广泛的应用。汽车的发动机、变速箱、车桥、车架、车身、车厢六大总成都离不开焊接技术的应用。但对于汽车车身生产厂来说,由于点焊、气体保护焊、钎焊具有生产量大,自动化程度高,高速、低耗、焊接变形小、易操作的特点,所以对汽车车身薄板覆盖零部件特别适合,因此,在汽车生产中应用最多。一般情况下,点焊能约占75%,其他焊接方法只占25%。
Welding is a necessary modern machinery manufacturing process technology, while in the automotive manufacturing has been widely used. Automotive engine, transmission, axle, frame, body, car six assembly are inseparable from the application of welding technology. However, for automotive body manufacturers, due to spot welding, gas shielded welding, brazing with a large amount of production, high degree of automation, high speed, low consumption, welding deformation is small, easy to operate features, so the car body sheet covered parts Particularly suitable, therefore, the most widely used in automobile production. Under normal circumstances, about 75% of spot welding energy, other welding methods only 25%.
