Example Embodiment
[0025] In order to deepen the understanding of the present invention, specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings:
[0026] The present embodiment provides a thin-walled plate flux-cored wire gas-contained vertical upward welding process method, including the following steps:
[0027] ①From the vertical seam of the thin-walled plate in the vertical cylinder project, select the wall thickness study range (6-10mm), and adopt the welding process method of forced forming of self-shielded flux-cored wire and single-sided water-cooled copper gasket;
[0028] ② Use mechanical processing methods to cut and bevel the thin-walled plate to be welded, and perform derusting, degreasing and decontamination near the bevel of the thin-walled plate;
[0029] ③The welding process of the vertical cylindrical thin-walled plate is prone to shrinkage of the weld, so the unequal assembly gap is used to control the anti-...
