A Welding Method for Circumferential Weld on Exhaust Tube

Abstract

The invention discloses a welding device and a welding method for the circular seam on the exhaust cylinder. The welding device used for the circular weld seam on the exhaust cylinder includes a clamping assembly arranged on the workbench , a support frame fixedly installed on the workbench, a displacement assembly located on the support frame, an adjustment plate disposed on the displacement assembly, and a welding assembly disposed on the adjustment plate. This device can greatly increase the welding speed, and is also equipped with a locking device, which can realize the clamping of the connecting rod during the repair welding work, so as to avoid the displacement of the exhaust cylinder during the repair welding process, which will cause Failure of repair welding work.

Description

technical field [0001] The invention relates to a welding device, in particular to a welding method for a circular weld on an exhaust cylinder, and relates to the technical field of a circular weld welding device. Background technique [0002] The circular seam welding machine is mainly used for butt welding of stainless steel circular workpieces. When manufacturing cylindrical containers, most of them divide the container into many different parts, and then weld these parts together, which can be used to manufacture different parts. Shaped cylindrical container. [0003] But this welding device also has some problems, most of the existing welding devices have only one welding position, and then when the welding work, when the diameter of the exhaust pipe is larger, the area of ​​the circular seam that needs to be welded will be Increase, which in turn will increase the difficulty of welding, which in turn will lead to an increase in welding time, which in turn will result ...

AI Technical Summary

Problems solved by technology

[0003] But this welding device also has some problems, most of the existing welding devices have only one welding position, and then when the welding work, when the diameter of the exhaust pipe is larger, the area of ​​the circular seam that needs to be welded will be Increase, which in turn will increase the difficulty of welding, which in turn will lead to an increase in welding time, which in turn will result in a decrease in welding speed

[0004] In order to increase the welding speed, some enterprises will choose to use two welding devices, and then through the installation of multiple welding devices, the welding work on the exhaust pipe can be completed at the same time, but most of the welding devices are located in the length direction of the exhaust pipe On the other hand, when the diameter of the exhaust pipe is larger, the welding time is the same as that of a single welding device, and the welding time cannot be reduced
