The air jet 508 is connected to a high-pressure gas tank through a pipeline, and an inert gas can be sprayed for protection during welding.

[0032] In this embodiment, different sizes of stainless steel elbows can be accommodated by replacing welding heads 509 of different lengths.

[0033] In this example, after the upper cover 510 is closed, the second cylinder 512 controls the fixing frame 513 to move downward, pressing the bump on the upper cover 510 from above.

[0034] In this example, by providing the mounting frame 102, the mounting position of the bracket 5 can be adjusted, so as to facilitate the adjustment of the position of the closed tube-to-tube welder 505 according to the different bending degrees of the elbow; In this example, the third motor 502 is started to drive the third screw rod 503 to rotate, which can drive the closed tube-to-tube welder 505 to move on the sliding frame 501. By setting an electric rotating platform 504, the closed tube-to-tube welder 505 can be driven to rotate and adjust the angle.

[0035] In this example, the closed tube-to-tube welder 505 adopts argon arc self-melting welding technology, without the need for wire filling, and achieves the effect of single-sided welding and double-sided forming by filling the inside of the round tube and the welding gun with argon for protection during welding.

[0036] The working process and principle of the present invention are as follows: when welding a stainless steel elbow, the second connecting rod 302 is supported at the bending part of the stainless steel elbow, and one end of the second connecting rod 302 is positioned to the center position of the bending part of the stainless steel elbow by pushing the stainless steel elbow, and the stainless steel elbow is positioned by the fixed frame 214 and the second connecting rod 302. After the positioning is completed, the third motor 502 is started to drive the third screw rod 503 to rotate and drive the closed tube-to-tube welder 505 to move on the sliding frame 501, so that one end of the elbow is inserted into the welding part of the closed tube-to-tube welder 505, and the straight pipe is inserted into the welding part of the closed tube-to-tube welder 505 and aligned with one end of the elbow, and welding is performed by the closed tube-to-tube welder 505.
