Description

Technical Field

[0001] This utility model relates to the field of steel structure welding technology, specifically to a weld seam correction device for steel structure welding. Background Technology

[0002] Welding is a crucial step in the production and processing of steel structures. With the widespread application of steel structures in fields such as construction and machinery manufacturing, the requirements for welding quality and efficiency are becoming increasingly stringent. The quality of the weld not only directly affects the strength and stability of the steel structure but also relates to the safety and service life of the entire structure. However, in actual welding processes, due to factors such as dimensional deviations of the steel structure, thermal deformation during welding, and differences in the skill level of operators, weld misalignment often occurs, seriously affecting welding quality and even leading to product scrap.

[0003] Currently, weld seam correction methods mainly rely on manual operation. Welders rely on their experience to observe the weld seam position with the naked eye and manually adjust the position of the welding equipment to achieve correction. This method is not only labor-intensive, but also has low correction accuracy, making it difficult to meet the requirements of modern high-precision welding. The efficiency of manual operation is low and cannot meet the needs of large-scale industrial production. Utility Model Content
