Study on the process of double-electrode gas metal arc welding system

A novel prccess,referred to as Double-Electrode Gas Metal Arc Welding and introduced the basic principles of it.Through large amount of experiments,the geometrically matched paramenters in torchset up of DE-GMAW (double electrode-gas metal arc welding) were found,designed of welding electrical signal acquisition system and the welding voltage waveforms,welding current waveforms,and welding seam without defects were obtained.Based on these test results,the reason that DE-GMAW can realize high-efficiency welding were explained.Extensive studies have been conducted to uncover the fundamental characteristics of the DE -GMAW process.Double-bypass MIG arc welding is a kind of improved arc welding by its nature,the productivity of welding process has been effectively improved by substantially increase the deposition rate on the premise of the ensurence of the quality of welding.
