In this article, it introduced technology characteristics and industrial production advantage of SAWH pipe by two-step welding process. Aiming at high-speed helical forming of two-step welding, it carried out systematic analysis on influencing forming stability factors, such as raw material, equipment level, forming parameters, commissioning quality and production monitoring adjustment etc. Some effective control measures were put forward, which provided a certain reference and guidance for further application of SAWH pipe, the pre-welding unit process(equipment)design and the pre-welding pipe production.
