| description | The gas protection device for the deep hole welding process comprises a first blocking piece and a second blocking piece detachably connected with the first blocking piece, the first blocking piece and the second blocking piece are oppositely provided with abutting parts, and the abutting parts abut against the periphery of a heat exchange tube. The gap between the inner side of the first blocking piece and the periphery of the heat exchange pipe is kept consistent with the gap between the inner side of the second blocking piece and the periphery of the heat exchange pipe. By arranging the first blocking piece, the second blocking piece and the abutting part, the abutting part abuts against the outer portion of the heat exchange pipe, so that the gap between the first blocking piece and the heat exchange pipe is kept consistent with the gap between the second blocking piece and the heat exchange pipe, and therefore protective gas is evenly dispersed on the peripheral side of the welding position, and the qual |
