Abstract
Welding equipment is a machine which is used in welding production and welding processes, and it is conducive to welding production mechanization and automation, to improving assembly welding-quality. Then it could prompte to speed up the process of welding production of the various assistive devices and equipment. Welding roller is used initiative and welding pieces of the wheel between the Mount relay driven welding rotating mechanical deformation. Welding roller stands for the main pieces of tube welding and welding assembly. Welding roller standing by structural form is divided into two categories : the first category is long axis-wheel frame., the second category is modular roller frame. In this paper, four pairs of modular T-welded wheel for the design, as well as axial, bond and other main component of checking. The results showed that the main components to meet the requirements. The roller frame structure is simple, flexible, adaptive welded pieces of a strong, which is the most widely used form of the structure. And it could be fully considered the roller frame reasonable and economic, and other factors.
