摘要:
To start consumable electrode arc welding, an initial current is supplied to a welding wire after causing the welding wire to contact a base material and retracting the welding wire from the base material. In this manner, an initial arc is generated. The welding wire is retracted continuously for an initial arc lift period Ti with the initial arc maintained. Afterwards, the initial arc is switched to a steady arc. A predetermined weld pool formation period Tp is set after the initial arc lift period Ti. In the weld pool formation period, a weld pool formation current greater than the initial current is supplied with the initial arc maintained and the welding wire is caused to proceed and fed to the base material. In the weld pool formation period, a weld pool is formed by the initial arc without allowing the welding wire to release droplets and contact the base material. By this method, the initial arc is switched to the steady arc state after the weld pool has been formed. This suppresses generation of spatter caused by transfer of the droplets to the base material.
摘要(中):
为了开始消耗性电极电弧焊接,在使焊丝接触基材并从基材回缩焊丝之后,向焊丝供给初始电流。 以这种方式,产生初始电弧。 在初始电弧保持时,焊丝连续退回初始电弧提升期间Ti。 之后,将初始弧切换成稳定的弧。 在初始电弧提升期间Ti之后设定预定的熔池形成周期Tp。 在焊池形成期间,提供大于初始电流的熔池形成电流,初始电弧保持并且焊丝进行并馈送到基体材料。 在熔池形成期间,通过初始电弧形成焊池,不允许焊丝释放液滴并接触基材。 通过这种方法,在形成焊池后,初始电弧切换到稳定电弧状态。 这抑制了由于将液滴转移到基材而引起的飞溅物的产生。
