电弧气刨作为一种高效率的焊接坡口制备方法在造船和机器制造业中已广泛应用,并且还可以在车辆修理企业中采用。这种方法可以大大减少开焊接坡口时的劳动量。但是这种方法只有在能保证焊接结构有足够的抗冷脆性水平的条件下才能应用。电弧气刨同时又会引起焊接制备坡口金属的增碳。显然,提高含碳量会降低焊接接 Arc gouging has been widely used in the shipbuilding and machine building industries as a highly efficient method of welding groove preparation and can also be used in vehicle repair shops. This method can greatly reduce the amount of labor when welding a groove. However, this method can only be applied if the welded structure has adequate resistance to cold embrittlement. Arc gouging at the same time will lead to the welding preparation of beveling metal carbon. Obviously, raising the carbon content will reduce the soldered joints
