Embodiment Construction
[0012] An automatic welding method for 2205 dual-phase steel, the method refers to: respectively adopting a PAW / TIG double-gun switching longitudinal seam automatic welding system and a PAW / TIG double-gun switching circular seam automatic welding system to weld the longitudinal seam and the circumferential seam of a cylinder.
[0013] When the plate thickness of the 2205 duplex stainless steel cylinder is 4~10mm, the I-type groove type is adopted, the groove planer is a straight edge and the straight edge is connected, and the automatic PAW (plasma arc welding) without filler wire is used for self-fluxing welding first. 1 time, and then switch to the automatic argon arc welding wire filling cover for 1 time.
[0014] When the plate thickness of the 2205 duplex stainless steel cylinder is 10~15mm, adopt the Y-shaped joint groove type, the groove angle is 75°, the single side is 37.5°, and the blunt side is 6mm. Automatic PAW (plasma arc) is not used to fill After 1 pass of wire...
