Double two-sided synchronous tungsten electrode high-frequency pulse argon arc welding butt welding method

A double two-sided synchronous tungsten electrode high-frequency pulse argon arc welding butt welding method is implemented by the following steps: cleaning up sundry, carrying out groove processing on the welding position of a wall plate of a stainless steel storage tank, welding position welding, choosing welding torch equipment, aligning a same weld pool by a main welding torch and an auxiliary welding torch from the inside and outside of a weld joint respectively synchronously, arcing synchronously by the main welding torch and the auxiliary welding torch, enabling the auxiliary welding torch to be moved synchronous to the main welding torch, welding along the same direction at the same speed, and stopping arcing by the main welding torch and the auxiliary welding torch synchronously. By adopting the double two-sided synchronous tungsten electrode high-frequency pulse argon arc welding butt welding method, the inner side forming of the weld joint is protected and penetrated, the defects of oxidation, over
