The embodiment of the invention provides a welding method for tubular parts, the tubular parts are vertically arranged, and the welding method comprises the steps that welding operation is conducted on the butt joint position of every two adjacent tubular parts arranged in the vertical direction from the outer portions of the tubular parts; detecting a welding position and determining a welding defect position; and repair welding operation is conducted on the welding defect position from the interior of the tubular part. According to the welding method of the tubular part, welding operation is conducted from the outside of the tubular part, the operation efficiency is improved, repair welding operation is conducted from the inside of the tubular part, repair welding can be conducted on the welding defect position on the inner wall of the tubular part in a targeted mode, and the welding quality of the tubular part is improved. The tedious steps of removing the filler from the outer wall of the tubular part and then performing repair welding and filling in the related technology are avoided, the operation time is saved, and the operation efficiency is improved; and meanwhile, the repair welding effect on the inner wall can be directly observed in the repair welding operation process, and the success rate of repair welding operation is increased.
Description
technical field [0001] The invention relates to the technical field of engineering, in particular to a welding method for a tubular part. Background technique [0002] In the cryogenic rectification system, it is necessary to weld and install a large number of vertically placed tubular parts. The quality requirements of the weld seam are high, and the defects generated in the weld seam need to be remedied to meet the use requirements. [0003] In the related art, the filler at the welding defect is excavated from the outer wall of the tubular part, and then repaired welding is performed again. This method has a large workload and low efficiency, and the repair welding effect on the inner wall cannot be directly observed, so there is a high risk of repair welding failure. Contents of the invention [0004] In view of this, the embodiment of the present application expects to provide a welding method for tubular parts that improves the success rate of repair welding.
