Description
technical field [0001] The invention relates to the technical field of automatic adjustment of arc voltage for gas tungsten electrode shielded welding, in particular to a multi-mode automatic arc voltage adjustment control system. Background technique [0002] Since the reform and opening up, my country's industry has developed rapidly. Welding plays an important role in industrial production and plays an irreplaceable role in various production constructions. Industrial development drives the development of welding technology at the same time. However, for the overall welding engineering technology in our country, there are still many problems. Among them, the insufficient popularity of automated welding is one of the problems that need to be solved urgently. Automatic welding can realize automatic control, and carry out independent operations according to production needs and on-site instructions, thereby improving welding quality and efficiency, effectively reducing labo...
