药芯焊丝电弧焊既有涂药焊条手工焊的良好质量,又有实芯焊丝电弧焊那样高的生产效率。因而为国外焊接行业所重视。药芯焊丝气体保护电弧焊自问世以来,一直在与涂药焊条手工焊和实芯焊丝CO_2保护焊争高低。最近由于称为“二代”药芯焊丝的发展,促使这种方法的应用不断增长。目前,国内还很少见到应用。 Flux-cored wire arc welding both coated electrode of the good quality of manual welding, but also solid-core wire arc welding that high production efficiency. Therefore, the importance of foreign welding industry. Flux cored wire gas shielded arc welding since its inception, has been coated with coated electrodes and manual welding wire CO_2 protection welding competition level. Recently, due to the development of “second generation” flux cored wires, the use of this method has been steadily increasing. At present, the domestic rarely seen application.
