The common welding method is that the inner welding seam and the outer welding seam are respectively welded, and manual welding is mainly used, so that the welding efficiency is low, and the labor intensity of workers is high. Therefore, a welding mode of single-side welding and double-side forming is adopted subsequently, and the welding mode is realized through the steps of backing welding, filling and cover surface welding.
In order to prevent welding collapse, workers also generally need to enter the cylinder to support the welding seam area inside the cylinder during welding so as to prevent welding collapse. For example, chinese utility model patent with an authorization publication number of CN203610906U discloses a supporting tool, which is pushed against the inner side of the butt joint of two cylinders when in use, thereby playing an anti-deformation effect. The support frock of prior art can only realize supporting the inside purpose in order to prevent the barrel and warp to the barrel, but because the barrel need prevent that the inboard circumstances that point discharge appears of welding seam when using, carrying out the two-sided shaping in-process of single welding, need finalize the design to the inboard of welding seam to guarantee that the welding seam inboard does not take the closed angle. In order to achieve the purpose, in the prior art, a worker enters the cylinder before welding, a circle of ceramic plates with arc-shaped grooves are adhered to a welding seam, the inner side of the welding seam is shaped through the arc-shaped grooves during welding, and the worker needs to enter the cylinder again after the welding is finished to take down the ceramic plates. The labor intensity is high due to the fact that workers need to enter the barrel body to work. Moreover, the supporting deformation prevention and the ceramic wafer adhesion of the cylinder are two processes, so that the processes are complicated, and the overall efficiency is low.
