Description

Technical Field

[0001] The invention belongs to the technical field of pressure vessel manufacturing and welding, and in particular relates to an automatic teaming assembly and automatic spot welding device for annular seams of cylinder sections of a pressure vessel. Background Art

[0002] For thin-walled cylinder sections of pressure vessels, especially stainless steel cylinder sections, the annular seams are usually welded by plasma welding technology or deep-melting TIG (or K-TIG) welding technology. For welds with a wall thickness of less than 8 mm, no groove welding is required to achieve single-sided welding and double-sided forming. This advanced and efficient welding method has very high requirements for the assembly gap and misalignment of the annular seam, which cannot exceed 10% of the plate thickness. That is to say, for a cylinder section with a plate thickness of 8 mm, the assembly gap and misalignment of the annular seam should be less than 0.8 mm. The assembly quality of the annular seam will directly affect the welding quality. The existing annular seam assembly method usually adopts a manual assembly method, which uses a crane to place the cylinder section on the supporting roller, and uses hydraulic or pneumatic methods to slightly lift the lower part of the annular seam at the outer side of the cylinder section. Then the welder manually spot welds the lifted part at the bottom of the cylinder section, and then rotates the cylinder section by an angle to repeat the above process. The assembly quality is closely related to human factors. Manual assembly is time-consuming, unstable in quality and inefficient. Summary of the invention
