Synchronous flaw detection device for boiler barrel welding

Abstract

The invention discloses a synchronous flaw detection device for boiler barrel welding, and belongs to the technical field of welding. The synchronous flaw detection device comprises an operation table and a synchronous flaw detection device body. The synchronous flaw detection device body is mounted on the operation table and comprises a synchronous assembly, an outer side detection and welding integrated device and an inner side detection and welding integrated device. The synchronous assembly is mounted at the top of the operation table. The outer side detection and welding integrated device and the inner side detection and welding integrated device are arranged on the synchronous assembly at intervals. According to the synchronous flaw detection device, the inner side detection and welding integrated device extends into a barrel to detect the welding problem of the barrel, the outer side detection and welding integrated device detects the outer wall of the barrel outside the barrel, the inner wall and the outer wall of the barrel are welded at the same time, and therefore it is guaranteed that the temperature of the inner side and the temperature of the outer side are consistent in the barrel welding process; and the problematic part of the welding position is perfectly repaired, the welding quality is improved, and a product is more attractive.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a simultaneous flaw detection device for boiler shell welding. Background technique [0002] At present, the welding process is used in the manufacturing process of the boiler shell and so on. Due to the large residual internal stress at the weld seam of the steel tank after welding, long-term contact with corrosive substances during use can easily lead to stress corrosion cracking at the weld seam, resulting in brittle fracture accidents, causing casualties and major economic loss. [0003] The Chinese invention patent with the existing publication number CN108655542A discloses a boiler shell intelligent welding synchronous flaw detection detection device, which belongs to the boiler welding detection technology, including an intelligent automatic welding device, an X-ray generating device, a weld seam camera image processing system, a welding removal The slag device and the ...

AI Technical Summary

Problems solved by technology

[0005] The embodiment of the present invention provides a boiler cylinder welding synchronous flaw detection device to solve the problem of detecting the boiler cylinder from the outside of the boiler cylinder when the boiler cylinder is found to be welded during the simultaneous welding flaw detection of the boiler cylinder. The cylinder is repaired by one-sided welding, which leads to technical problems such as uneven temperature of the boiler cylinder, low quality of the weld, and poor aesthetics during the welding process of the boiler cylinder
