切割和开坡口的质量对随后的焊接制造过程具有非常大的影响。不精确的切割和开坡口会造成错误的装配,进而导致不令人满意的焊接及随之而来的返工成本。大型的制造工厂可以采用等离子、激光、水刀、氧乙炔切割或者碳弧气刨等数控切割设备准确地进行这些工作。而对于较小的工厂,仅限使用直线行走或圆形切割的可变速小车,或者依靠工人的个人技能,但是其最大的风险 The quality of the cut and the groove have a very big influence on the subsequent welding process. Inaccurate cutting and beveling can result in incorrect assembly, resulting in unsatisfactory welding and subsequent rework costs. Large manufacturing plants can do this precisely using plasma, laser, waterjet, oxyacetylene cutting, or CNC arc gouging and other CNC cutting equipment. For smaller plants, only variable speed cars that use straight walking or circular cutting, or rely on the worker’s personal skills, but their greatest risk
