Description

Technical Field

[0001] The utility model relates to the technical field of welding, and specifically relates to a roller welding workbench. Background Art

[0002] Roller welding is a process used to manufacture metal products such as rolls. It usually uses a heat source to connect two metal billets of different diameters to form a continuous roll. Roller welding requires the use of specialized welding equipment, such as plasma arc welders, laser welders, etc. These devices can provide high temperatures and high energy density to melt the metal billets and connect them together.

[0003] When welding rollers, the high temperature generated during the welding process causes the metal blank to deform and shrink. If the position cannot be stabilized, the weld quality will be affected. For example, the weld is discontinuous, the weld width is too large or too small, and the weld depth is not appropriate. These defects will affect the service life and performance of the roller. Since the welding process requires fixed control, if the workbench operation process is cumbersome, it is also very easy to make mistakes. Therefore, we propose a roller welding workbench to optimize welding and other aspects to ensure that the welding quality meets the requirements. Utility Model Content
