Description

Technical Field

[0001] The utility model relates to the technical field of welding quality inspection machines, in particular to a welding quality inspection machine. Background Art

[0002] Welding, also known as fusion or melting, is a manufacturing process and technology that uses heat, high temperature, or high pressure to join metals or other thermoplastic materials such as plastics. Modern welding uses a variety of energy sources, including gas flame, arc, laser, electron beam, friction, and ultrasonic waves. The quality of the weld determines the performance of the workpiece. Steel pipe welding involves aligning the ends of two sets of steel pipes of the same size before welding. The weld quality needs to be inspected after welding, so a welding quality inspection machine is provided.

[0003] The existing technology still has many shortcomings. For example, after the steel pipe is welded, the inspector needs to move the inspection head along the weld to perform welding inspection. During manual inspection, the welding head and the weld are easily deviated, resulting in deviations in the inspection data, which affects the subsequent use of the steel pipe. Utility Model Content
