Description

Technical Field

[0001] The invention relates to the field of welding tooling, and in particular to an ARM displacement integral welding tooling for a power tower. Background Art

[0002] During the production of the ARM of the Danish power tower, welding is difficult, the deformation is large, and the welding quality requirements are high. The current welding method in the industry is manual welding, which is difficult to weld, resulting in high labor intensity, limited working time, low welding efficiency, and low welding quality. The ARM of the power tower is directly placed on the ground for splicing and welding. The welder can only squat or bend down to weld. After welding a certain distance, the position needs to be adjusted before the next welding. After welding for a period of time, the welder needs to stop working and enter the rest area to rest. After welding, the weld formation and ARM deformation are checked. The places where the welding is not in place are reworked, and the places where the ARM is deformed are corrected. Therefore, the existing working method has the following defects: (1) The welder has high labor intensity, cannot work continuously, and has low welding efficiency; (2) The ARM is placed on the ground, and the welder can only squat or bend down to weld, cannot weld continuously, has low welding efficiency and poor welding quality; (3) Direct manual welding has a large welding volume and large deformation; (4) The welding groove is a natural groove, and the weld formation is not good; (5) Direct manual welding leads to low welding quality, large deformation, and high rework rate.

[0003] Therefore, in response to this series of problems, we have designed a set of variable position integral welding tooling, which can flip the angle, reduce labor, improve welding efficiency and welding quality; adding a pressure plate to the weld reduces welding deformation.
