Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of welding devices, and in particular, to a welding device and a welding method for producing power towers. Background Art

[0002] During the manufacturing process of power towers, diagonal braces are key components for ensuring the tower's structural stability. The quality of their welding directly impacts the tower's overall mechanical properties and service life. Because power towers must adapt to complex outdoor environments and withstand loads such as strong winds and icing, diagonal braces are often welded to the main frame in a cross pattern, forming a triangular stabilization system. This places extremely high demands on the welding precision and strength at the intersection of the two diagonal braces. At present, the welding operation at the intersection of two diagonal braces is mostly completed by manual handheld welding guns or semi-automatic welding equipment. However, during the welding process, the two diagonal braces need to be crossed and the angle maintained fixed. During the contact between the welding gun and the diagonal brace plates, the pressure of the welding gun on the diagonal brace plates can easily cause the angle between the diagonal brace plates to deviate, thereby affecting the welding effect between the diagonal brace plates.
