A method of controlling an arc welding system during a welding process is disclosed. The welding process has a plurality of welding cycles in which a consumable electrode is advanced towards a workpiece. The method includes dynamically regulating a rate of advancement and instantaneous melt rate of the electrode during each welding cycle in response to predetermined events occurring during the welding process. The melt rate may be coordinated with the rate of advancement of the electrode to provide a wide range of stable deposition rates with a shielding gas such as CO<SUB>2</SUB>. An arc welding system for carrying out the method is also disclosed.
(ZH) 公开了一种在焊接过程中控制电弧焊接系统的方法,焊接过程具有多个焊接周期,其中将可消耗的电极(14)向工件(16)推进。该方法包括响应于焊接过程中发生的预定事件,在每个焊接周期中动态调节电极的推进速度和瞬时熔化速度。电极的熔化速度可以和推进速度协调,以提供宽范围的稳定沉积速度,同时使用保护气如二氧化碳。也公开了用于实施该方法的电弧焊接系统。
