The middle part of the gas transmission pipeline 1 is vertically provided with a supporting bolt 6, and the supporting bolt 6 and the gas transmission pipeline 1 form a cross shape to be fixedly supported inside the cylindrical sealing shell 2. The middle part of the gas transmission pipeline 1 is also respectively connected with an argon conveying belt 4 and a traction chain 7, and the argon conveying belt 4 is inserted into the gas transmission pipeline 1 for supplying gas. The high-elastic sponge 3 is bonded at the two ends of the outer side of the cylindrical sealing shell 2 through glue, and an annular argon gas chamber 9 is formed between the high-elastic sponge 3 at the two ends and the cylindrical sealing shell 2. One end of the gas transmission pipeline 1 penetrates through the cylindrical sealing shell 2 to form a gas inlet 5, and the gas transmission pipeline 1 is communicated with the annular argon gas chamber 9 through the gas inlet 5. An argon distribution pipe 11 is arranged in the annular argon chamber 9, the argon distribution pipe 11 is communicated with the gas transmission pipeline 1, and air holes 12 are uniformly distributed on the argon distribution pipe 11. The argon distribution tube 11 allows a rapid and uniform distribution of the gas.
When in use, the traction chain 7 and the argon conveying belt 4 are connected to the gas transmission pipeline 1; the whole device is plugged into two sections of stainless steel pipelines 8 to be welded, the stainless steel pipelines 8 can be elbows, flanges, straight pipes, tee joints, reducing pipes and the like, and the distribution pipes with small holes of the tool are positioned at the bottom sides of the welding seams.
The position of the whole device is adjusted by a traction chain 7, so that the welding seam is positioned at the center of the whole device.
The weld joint group is fixed by parallel spot welding, and the other parts of the weld joint are sealed by paper tapes 10 except that 20mm is reserved at the upper part of the weld joint as an exhaust point. At this time, except for the reserved exhaust point, the annular argon gas chamber 9 is enclosed by the high-elasticity sponge 3, the cylindrical sealing shell 2, the stainless steel pipeline 8 and the paper adhesive tape 10 to form a closed state.
And (4) connecting the argon conveying belt 4, filling argon into the annular argon chamber 9, and replacing the air inside.
After the argon replacement is finished, welding is carried out, and after 2 layers are welded, argon filling can be stopped or the flow of argon can be reduced.
After welding, the whole device is slowly pulled out through the traction chain 7, and the whole device is used.
