Problems solved by technology
However, due to the larger volume of the cylindrical workpiece and the thinner wall thickness, the cylindrical workpiece as a whole is not a rigid workpiece to be welded, but flexible, which makes it difficult to align the opposite sides of the two cylindrical workpieces. The current welding method often requires the side-to-side operation of the two cylindrical workpieces, and the welding of the parts of the two cylindrical workpieces that have completed the side-to-side welding, resulting in a circular seam formed between the two cylindrical workpieces. Often it cannot be formed by one-time welding, not only the welding efficiency is low, but also the quality of the weld is not ideal after the weld is formed

The invention relates to a welding method, in particular to a circular seam welding positioning tool for a thin-walled cylindrical workpiece, comprising: a chassis, a plurality of clamps for opposite sides of the circular seam arranged on the chassis, each of the clamps for the opposite sides of the circular seam wraps around a The setting axis is set around the chassis, and each of the annular seam opposite side clamps is slidable on the chassis in a direction perpendicular to the preset axis, and is used to align all the first cylindrical workpieces from the inside of the first cylindrical workpiece. The first cylindrical workpiece is centered. Compared with the prior art, it is ensured that the circular seam formed between the two cylindrical workpieces can be welded at one time, and while the welding efficiency is improved, the quality of the circular seam after welding is also improved.
Description
technical field [0001] The invention relates to an assembly and welding method, in particular to a circumferential seam welding positioning tool for thin-walled cylindrical workpieces. Background technique [0002] Circumferential seam welding, as a welding method for welding two cylindrical workpieces together, is generally applied to some special products, such as pressure vessels. In the welding process, in order to ensure that the two cylindrical workpieces are butted without wrong sides, it is necessary to position the two cylindrical workpieces on the opposite sides before welding. However, due to the large volume and thin wall thickness of the cylindrical workpiece, the entire cylindrical workpiece is not a rigid workpiece to be welded, but flexible, which makes it difficult to meet the two cylindrical workpieces. The current welding method often requires two cylindrical workpieces to be opposite to each other, and at the same time needs to be welded to the part wher...
