With the rapid development of science and technology in our country, the advancement of high-end equipment manufacturing poses higher demands on product quality. As a core process that is irreplaceable and widely applied, welding quality directly affects product standards. However, the complexity of the welding environment and processes often results in weld seam defects, which severely impact the structural performance of welded components. Consequently, research on the detection of weld seam defects holds significant practical engineering value. This paper conducts a comparative study on various methods for detecting weld seam defects. It analyzes the characteristics and application scenarios of mainstream detection technologies, along with a comparative analysis of their advantages and disadvantages. Furthermore, this study explores the developmental gap in weld seam defect detection technologies within our country, aiming to contribute new ideas and methods for enhancing the capabilities of weld seam defect detection.
