The three-wave circular tube anti-blocking block submerged-arc welding automatic welding device has high degree of automation and the small floor area. The invention also relates to a welding method of the welding device.

Description

technical field [0001] The invention relates to a welding device, in particular to an automatic submerged arc welding device for three-wave circular tube resistance block submerged arc welding. Furthermore, the invention also relates to a welding method. Background technique [0002] The anti-blocking block of the three-wave circular tube is a device used to connect the three-wave guardrail board and the column of the guardrail. During production, the two ends of the formed anti-blocking block need to be welded together by a welding machine. At present, the submerged arc welding machine is generally used to weld it. When welding, the welding is driven on the guide rail by the walking trolley. During the walking process, the welding torch is aimed at the weld seam of the anti-blocking block and moves along it, so as to realize the anti-blocking. For the welding operation of the anti-blocking block, after the welding is completed, the operator needs to output the anti-blockin...

AI Technical Summary

Problems solved by technology

At present, the submerged arc welding machine is generally used to weld it. When welding, the welding is driven on the guide rail by the walking trolley. During the walking process, the welding torch is aimed at the weld seam of the anti-blocking block and moves along it, so as to realize the anti-blocking. For the welding operation of the anti-blocking block, after the welding is completed, the operator needs to output the anti-blocking block to the downstream of the welding station for subsequent operations such as scratching and deburring. Therefore, the length of the whole set of welding equipment is relatively long. It occupies a large area of ​​the factory building, and its space utilization rate is low, and the operator needs to manually move the anti-blocking block, so its work efficiency is also low
