Abstract
The present disclosure relates to the field of material processing, and in particular to a welding method for a metal piece, wherein the metal piece includes at least a plurality of first welding positions and a plurality of second welding positions, and the welding method includes: using the same welding torch Welding the first welding position and the second welding position respectively; wherein, when the welding wire on the welding torch moves to the first welding position and welds the first welding position, the welding torch A DC pulse current is applied; when the welding wire moves to the second welding position and welds the second welding position, the welding torch is applied with an AC pulse current. Adopting the welding method can reduce the welding heat while obtaining a large welding leg size, thereby improving the strength of the welding seam, reducing welding errors and reducing deformation of metal parts after welding.
Description
technical field [0001] The present disclosure relates to the field of material processing, in particular to a welding method for metal parts. Background technique [0002] At present, when welding metal parts, DC current welding or AC current welding is usually used. When using DC current to weld metal parts, the size of the welding pool is large, and its welding heat is difficult to control, resulting in large deformation of the metal parts after welding; when using AC current to weld metal parts, the size of the molten pool Insufficient heat, resulting in a lot of weld spatter and difficult to form welds. [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore it may include information that does not constitute the prior art that is already known to those of ordinary skill in the art. Contents of the invention [0004] The purpose of the...
