Technical Field

The utility model relates to the technical field of containers, in particular to welding equipment.

Background

At present, the yield of the Chinese container occupies 95 percent of the global container yield, and the welding quality of the container is higher and higher. At present, the production of containers is mainly completed by manual welding, and the manual welding has the problems of unstable welding quality, discontinuous welding bead, low efficiency and the like.

Therefore, there is a need for a welding apparatus to at least partially address the above issues.
