目前,气焊减应法在汽车、拖拉机和各类机械的修理上已有较多的应用,我们感到这是焊接汽车零件的一种好办法,特作如下介绍,供同志们参考。众所周知,铸铁的焊补一直是个“老大难”,国内外不少单位进行过研究和试验,也提出了不少修补方法,有的焊后仍旧易开裂;有的焊后不易加工;有的工序复杂被淘汰;有的往往受一些具体条件的限制(如焊接材料的来源等)而不易实施,这里所介绍的气焊减应法简 At present, the gas welding reduction method has been applied in the repair of automobiles, tractors and various kinds of machinery. We feel that this is a good way to weld automobile parts and is specially introduced as follows for your reference. As we all know, welding of cast iron has always been a “dilemma”, many units at home and abroad have conducted research and tests, but also proposed a lot of repair methods, and some are still easy to crack after welding; some after welding is not easy to process; some processes Complex is eliminated; some are often subject to some specific conditions (such as the source of welding materials, etc.) and not easy to implement, here describes the gas reduction method
