technical field

The utility model relates to a positioning tool, in particular to a casing welding positioning tool.

Background technique

Generally, in the welding process, the welding itself requires less man-hours, and more than 2/3 of the total man-hours are auxiliary work for welding, which greatly affects the welding speed.
