The arc melts the metal and the filler material completely. No pressure is required. The filler metal part all comes from the electrode. The electric fusion welding device is one of the indispensable devices in the work of welding gas pipelines. The workers welded two gas pipelines together by using a fully automatic electric fusion welding device.

[0003] After searching, the existing patent (application number: CN 219521088 U) discloses a fully automatic electric fusion welding auxiliary device for gas pipe docking, including a first bracket and a second bracket, a guide rod is fixed between the first bracket and the second bracket, a partition block is fixed on the guide rod, and compression springs sleeved on the guide rod are provided on both sides of the partition block. A pipe hanger is fixed at the bottom of the moving ring, and a clamping plate is fixed at the top of the moving ring. A driving rod is clamped in the clamping plate, and a plurality of driving teeth are fixed on the opposite side of the driving rod. A driving assembly for driving the driving rod to move in different directions is fixed on the top of the partition block. First, the pipes to be welded are fixed in the pipe hanger respectively, and then the two driving rods are driven to move in the direction of the compression spring by the driving assembly. The driving rod drives the moving ring to move along the guide rod, so that the moving ring drives the pipe hangers to approach each other until the pipes to be welded are coaxially docked. The structure is simple and the design is ingenious. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] When welding the gas pipe, the two gas pipes need to be clamped and fixed, but the existing clamping structure cannot be adjusted according to the size of the gas pipe, resulting in too little clamping force during the clamping process, and the pipe may move or shake during the welding process. If the clamping force is too large, the pipe may be deformed and damaged. At the same time, the existing method cannot ensure the coaxiality of the two pipes when they are butt-jointed during welding;

[0005] Therefore, in view of the above problems, a fully automatic electric fusion welding auxiliary device for gas pipeline butt joint is proposed. Utility Model Content
