What Are The Advantages And Disadvantages Of Lsaw?

Advantages: Mature forming process, easy to ensure welding quality; The residual stress is small after the pipe is expanded; Good geometric accuracy and mechanical property; It can reach high steel grade (≥ X120) and large wall thickness (≥ 40mm). Limitation: the diameter is limited by the plate width (generally ≤ 1422mm); Expensive investment in UOE molding; Less economical with diameter<406mm.
