In this article, it analyzed the characteristics of several key technological parameters of influencing HFW pipe product quality and welding efficiency, such as welding heat input, welding pressure, welding speed, opening corner size, the location and size of induction coil, impedor location and so on. The results indicated that it should rationally control welding heat input, extrusion quantity control in 2.5~3 mm in general, welding V Angle control in 4°~5°, induction coil width is 1~1.5 D of steel pipe diameter, the distance from the squeezing roller center to induction coil is in 1~1.2 D. Only under condition of unit capacity and welding device allow, the production is conducted at high welding speed as much as possible, it can obtain high weld quality and improve welding efficiency.
