Abstract

The invention discloses a welding seam detection method used for a bent electronic pipe fitting. The welding seam detection method comprises a vacuum detection stand, wherein the vacuum detection stand is equipped with a mobile base, a stand column is arranged on the mobile base, and a supporting disc which can move up and down along the stand column is installed on the stand column through a locking pin. When the welding seam detection method is adopted, the electronic pipe fitting to be measured is installed on a detection panel, one end is communicated with an air exhaust hole, the other end of the pipe fitting is sealed through a rubber cushion block; and a lower cross arm is used for fixing the pipe fitting, and an upper cross arm is used for guiding and supporting the pipe fitting. According to the welding seam detection method, the vacuum detection stand is equipped with the mobile base, the stand column is arranged on the mobile base, the supporting disc which can move up and down along the stand column is installed on the stand column through the locking pin, and the middle part of the bent pipe fitting is placed on the supporting disc and serves as a third supporting point of the bent pipe fitting, so that the welding seam detection of bent pipe fittings of any shape structure can achieved.

Description

technical field [0001] The invention relates to the inspection field of electronic pipe fittings, in particular to a weld detection method for curved electronic pipe fittings. Background technique [0002] In the production of welded structures, the quality of the welds obtained by the welding technology currently used has not yet reached sufficient stability. Therefore, in order to ensure the quality of the welded components, the quality inspection of the welds must be carried out to ensure that the welds comply with the specified technology. Requirements and safe use of structures. Weld inspection is divided into two categories: non-destructive inspection and destructive inspection. Usually the inspection of welds in production is non-destructive inspection, such as visual inspection, compactness inspection, etc. [0003] Visual inspection of welds has two components. [0004] 1. Inspection of weld shape and size: Weld shape inspection is to use measuring tools to detec...
