Abstract

The invention provides a weld joint morphology monitoring method, system and device and a readable storage medium. The method comprises the following steps: welding the target welding part according to the target process parameters, and acquiring a welding joint image acquired in the welding process and temperature information corresponding to each pixel in the welding joint image to obtain a reconstructed welding joint morphology, searching a preset welding joint morphology database based on the target process parameters, and determining a target welding joint morphology corresponding to thetarget process parameters. The weld joint morphology of the target welding part is monitored by comparing the reconstructed weld joint morphology with the target weld joint morphology. According to the scheme, the weld joint morphology can be monitored in real time, and due to the fact that the reconstructed weld joint morphology in the scheme can visually reflect the weld joint morphology of thetarget welding part in an image mode, visualization of the weld joint morphology is achieved, and observation is convenient.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a method, system, device and readable storage medium for monitoring the appearance of a weld. Background technique [0002] Welding technology is a crucial connection technology in industrial production, especially in the fields of shipbuilding, aerospace, nuclear energy and nuclear power, heavy industry machinery and automobile manufacturing. However, since the welding process is usually accompanied by strong arc light and radiation, it is difficult to monitor the welding process in real time, resulting in failure to find problems in time and resulting in quality defects. Contents of the invention [0003] The embodiments of this specification provide a method, system, device and readable storage medium for monitoring the appearance of a weld. [0004] In a first aspect, the present invention provides a method for monitoring weld seam appearance, comprising: [0005] When t...
