[0016] The present invention will be further described below with reference to the drawings and specific embodiments.
[0017] Such as figure 1 with figure 2 As shown, for the submerged arc welding process of large cylinders, a reference operating platform 1 is first laid with steel plates at the construction site. On the reference operating platform 1, the processing of marking, lofting, unfolding and splicing steel plates can also be performed on the cylinder. Straightening and welding treatment, the size of the platform depends on the size of the cylinder made on site, usually 120m 2 From left to right, the problem of no reference on site can be solved by setting up a reference operating platform. Then, in view of the difficulty of the on-site cylinder butt welding, a submerged arc welding bracket 2 for welding the cylinder is set up on the reference operating platform 1, and an automatic welding operation table 3 is set on the submerged arc welding bracket 2. The purpose of...
