[0002] With increasing competition across various industrial sectors, companies must improve the quality of their equipment and materials to ensure competitiveness in domestic and international markets. Welding, as a fundamental method for joining components, is widely used in construction, shipbuilding, aerospace, nuclear industry, petrochemicals, and numerous other fields. Welding quality is directly related to the performance and lifespan of welded structures. Due to environmental influences and welding processes, various defects such as porosity and slag inclusions are inevitable during welding. These defects can degrade the quality of welded components and significantly impact the performance of the structure. Welding failures can lead to system collapse at best, or even catastrophic consequences, resulting in severe economic losses and even casualties.

[0003] In existing welding detection devices, workpieces of different thicknesses require different focal lengths for detection, and the equipment needs to adjust the welding focus from different angles when welding the workpiece. This makes it easy for the detection instrument to shift its position when the equipment is detecting and marking the workpiece, causing problems with the detection results. In addition, when the equipment is fixing the workpiece, the clamping mechanism is prone to collide with the outer wall of the workpiece, causing damage to the outer wall of the workpiece, affecting the detection results. For this reason, an X-ray detection device based on weld defects is proposed. Utility Model Content
