Abstract

The invention provides a weld joint detection device and method, and relates to the technical field of weld joint detection, the weld joint detection device comprises a rack, a side sealing assembly,an air supply pressure measurement assembly and an upper sealing assembly, and a limiting block is arranged on the rack; the side sealing assembly is arranged on the side, away from the limiting block, of the rack and used for blocking a side opening of the weldment, and an air supply channel is formed in the side sealing assembly; the air supply pressure measurement assembly is connected to the side sealing assembly, and a pressure detection element is arranged on the air supply pressure measurement assembly; the upper sealing assembly is arranged on the rack, and the lower end is used for sealing an upper opening of the weldment. According to the weld joint detection device, the upper sealing assembly is used for blocking the upper opening of the weldment, the side sealing assembly is used for abutting against the side face of the weldment, air is supplied into the hole channel through the air supply pressure measurement assembly, and whether the weld joint leaks gas or not is accurately judged by detecting the pressure value in the hole channel; the welding quality of the weldment can be conveniently detected in the initial welding stage of a large component, the weld joint detection speed is increased, and repair welding can be conveniently conducted in time.

Description

technical field [0001] The invention belongs to the technical field of weld seam detection, and more specifically relates to a weld seam detection device and a method for using the weld seam detection device to perform weld seam detection. Background technique [0002] In order to improve the comfort of rail vehicles during operation, air springs are often used as the secondary suspension system of the vehicle bogie system. The frame formed by the above components is mainly composed of beams, side beams and empty spring guide columns welded on them, and is an important part of the bogie. The inner cavity of the steel pipe of the beam and some parts made of steel plates are welded to form an additional air chamber. The additional air chamber and the differential pressure valve work together to control the height of the air springs on both sides of the bogie. The additional air chamber must be strictly sealed. It will be impossible to control the height of the air springs on ...
