Abstract

The invention discloses a no-clean detection process for the welding seam of a titanium alloy assembly, which comprises a vacuum detection platform, on which a detection plate surface is connected through a closed telescopic opening, and a detection plate surface is provided with a vacuum An air pumping hole connected to the vacuum inside the testing platform; an alcohol storage box is also arranged on the vacuum testing platform, and a syringe is arranged on the alcohol storage box. The present invention uses a syringe to extract the alcohol in the alcohol storage box, and injects it at the sealing end of the pipe fitting, so that the sealing end is covered by alcohol, and then vacuum extraction is carried out on the vacuum detection platform. If the alcohol at the sealing end disappears obviously and quickly, it is proved The seal is good, if the alcohol disappears quickly, it means that the seal is defective, so adjust the seal end.

Description

technical field [0001] The invention relates to the inspection field of electronic pipe fittings, in particular to a no-cleaning inspection process for welding seams of titanium alloy assemblies. 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...
