[0002] Alloy pipe is a kind of seamless steel pipe, and its performance is much higher than that of ordinary seamless steel pipe. Because this kind of steel pipe contains more Cr, its high temperature resistance, low temperature resistance and corrosion resistance are unmatched by ordinary seamless steel pipe. Therefore, alloy pipe is widely used in petroleum, aerospace, chemical industry, electric power, boiler, military industry and other industries. In the process of alloy pipe welding, it is often necessary to clamp and fix it with clamping tooling to ensure high-quality welding.

[0003] In the prior art, when clamping alloy tubes, two fixed clamping seats are generally used to support the two alloy tubes respectively, and then two movable clamping seats are used to clamp and fix the two welding tubes respectively.

Furthermore, after the two alloy tubes are fixed, the alloy tubes cannot rotate during the welding process, and the staff needs to move back and forth to complete the welding. The fixation leads to low convenience of operation. Therefore, it is necessary to propose a stable alloy tube welding clamping tool to solve the above-mentioned problems. Utility Model Content
