Aim at the need of SAW pipe production, under the premise of ensuring the weld quality and production efficiency, the mathematical model of function relation among welding wire deposition, welding penetration, welding current, arc voltage and welding speed was set. The welding parameter of SAW pipe was designed under different welding speed, and was applied in production. Through comparison of weld performance and production efficiency of SAWH pipe with the same specification under different welding speed, the result showed that the design method and the determined parameters of high-speed welding process are reasonable. The pipe quality is stable after increasing speed, and the output can be increased by 20%.
