[0002] Welding, also known as soldering, is a manufacturing process and technology that joins metal or other thermoplastic materials through heating, high temperature, or high pressure. Welding is an important process method in mechanical processing, which can achieve the connection and repair of parts. However, due to the need for joint alignment, a tooling fixture is often used to clamp the steel pipe during steel pipe joint welding.

[0003] However, in the face of the diversification of steel pipe specifications in the market, traditional quick-release tooling fixtures face significant challenges in application. These fixtures are often designed based on fixed sizes or limited adjustment ranges, making it difficult to flexibly adapt to steel pipes of different diameters. This results in significant limitations in actual operation, as the fixture can only effectively clamp steel pipes of specific sizes. This not only increases production costs but also limits the flexibility and adaptability of the production line.

[0004] In addition, steel pipe joints are typically circular, which is a critical characteristic during welding. If the steel pipe is not properly rotated during the welding process, the circular joint will be difficult to weld evenly, leading to incomplete welding, missed welding, or uneven welding quality, which can further affect the overall strength and sealing performance of the steel pipe. Traditional fixtures often lack an active rotation mechanism when clamping the steel pipe, relying on manual adjustment of the steel pipe position. This not only increases labor intensity but also reduces the automation level and production efficiency of the welding operation. SUMMARY
