Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a welding angle adjustment device. Background Technology

[0002] With the advancement of technology, welding processes have placed new demands on the shaping and bending of materials. The thermal stress and deformation generated during the heating and cooling process of the welding head directly affect the quality and performance of the welding head. To ensure the reliability of the welding head and improve its welding effect, strictly controlling the welding angle is a crucial step in enhancing the welding performance.

[0003] When materials are bent, their shape changes, which can affect the accessibility of welding tools (such as welding torches and electrodes) to the welding area. For example, when welding on the inner corner with a small bending angle, the welding equipment may have difficulty reaching the target area, limiting the welding operation space.

[0004] The bending process creates stress concentration within the material. During welding, the heat input causes thermal expansion and contraction of the material, which, combined with the residual stress generated by bending, can lead to defects such as welding deformation and cracks if the combined stress exceeds the material's yield strength.

[0005] Therefore, it is necessary to strictly control the welding angle of the material to avoid the aforementioned problems. However, in the existing technology, the bending of the material is mostly done manually, and the positioning and bending of the material are usually carried out in steps. This is not only inefficient and has a low yield in high-pressure testing, but also makes it difficult to ensure the consistency of the material bending, which affects the final welding quality.
