Welding gas protection tool

The invention relates to the technical field of welding, in particular to a welding gas protection tool which comprises a tool body. The tool body is provided with a channel used for containing a workpiece to be welded. A protective gas circulating groove communicated with the channel is formed in the circumferential direction of the channel; the tool body is further provided with at least two air holes communicated with the protective gas circulating groove. The end face of the blind hole can serve as the positioning end face of the to-be-welded workpiece, so that the welding seam of the to-be-welded workpiece can be just located at the position where the protective gas circulating groove is located. Protective gas is introduced into the tool body from one of the gas holes, and is discharged from the other gas hole, so that the protective gas circularly flows in the protective gas circulating groove, and a relatively sufficient protective gas circulating space can be formed in a welding ...
