Straight seam steel pipe welding technology should pay attention to swing Several

Straight seam welding pipe welding current swing is slightly larger than traditional welding methods; secondly straight seam welded steel pipes sway in tungsten elongation determined according to the pipe wall thickness, typically 4-5mm; argon stream slightly larger than traditional welding methods about 8-10l / min; and finally straight seam welding pipe sway swing amplitude fusion 2mm slope at the mouth of two blunt edges; flexible with the right hand, swing uniform, wire evenly.

Straight seam steel pipe welding technology is generally used for swinging thick wall straight seam welded steel pipe. Law swing straight seam welded steel pipe technical parameters with the traditional linear welding method is slightly different compared to the first end portion of the porcelain mouth TIG slightly thicker than the traditional linear welding method, followed by a group of weld gap there are differences in 00Cr19Ni10 weld φ89 × 5 for example, the gap between traditional linear welding method is 0 ~ 3mm, while rocking law 4mm, welding specifications are different.
