Abstract

The invention discloses a no-clean welding seam detection method used for a bent electronic pipe fitting. The no-clean 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; an alcohol storage box is arranged on the vacuum detection stand, and an injector is equipped on the alcohol storage box. According to the no-clean welding seam detection method, the injector is used for extracting alcohol in the alcohol storage box and injecting the alcohol to a sealed end of the pipe fitting, so that the sealed end is covered with alcohol, then the vacuum detection stand is used for conducting vacuum extraction, if the alcohol at the sealed end does not disappear obviously and quickly, then the sealing is proved to be good, and if the alcohol disappears quickly, then the sealing is shown to be defective, thereby adjusting the sealed end.

Description

technical field [0001] The invention relates to the inspection field of electronic pipe fittings, in particular to a no-cleaning welding seam 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 meas...
