Problems solved by technology

However, due to the continuous movement of the welding torch during the welding process, it is difficult for the naked eye to detect when the weld trajectory deviates, which will lead to a decrease in the mechanical properties of the weld and seriously affect the final quality of components and products.

Abstract

The invention provides a weld joint track monitoring system comprising a monitoring assembly, a communication assembly and a data processing assembly. The communication assembly is in communication connection with the monitoring assembly and the data processing assembly. The monitoring assembly comprises an infrared detection device. When to-be-welded parts are welded, the infrared detecting device is used for collecting weld joint infrared images in the welding process. The communication assembly transmits the weld joint infrared images to the data processing assembly. The data processing assembly is used for determining the actual weld joint center line track in the welding process according to the weld joint infrared images and a target weld joint center line track and comparing the actual weld joint center line track with the target weld joint center line track, so that the weld joint track is monitored according to the comparison result. By the adoption of the weld joint track monitoring system, the weld joint infrared images can be collected and processed in real time in the welding process, the actual weld joint center line track can be obtained, so that real-time monitoringof the weld joint track is achieved, and deviation of the weld joint track is effectively controlled.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding seam trajectory monitoring system. 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. During the welding process, due to various factors, such as welding process, welding environment, etc., the welding seam trajectory will be offset. However, due to the continuous movement of the welding torch during the welding process, it is difficult for the naked eye to detect the deviation of the weld trajectory in time, which will lead to a decrease in the mechanical properties of the weld and seriously affect the final quality of components and products. Contents of the invention [0003] The embodiment of this specification provides a welding seam track monitoring system, inclu...
