1. Regardless of whether the straight seam steel pipe is rotated or fixed The cutting nozzle should be kept perpendicular to the surface of the straight seam steel pipe. After the cutting is completed, the cutting nozzle is gradually tilted forward at an angle of 70°-80° with the tangent line of the

The welding current in the swing welding of the straight seam steel pipe is slightly larger than that of the traditional welding method; secondly, the tungsten extreme elongation in the swing welding of the straight seam steel pipe is determined according to the tube wall thickness, usually 4-5mm; t
