Description

A portable electric welding machine for bolt production

Technical Field

The utility model relates to the technical field of electric welding machines, and in particular to a portable electric welding machine for producing bolts.

Background Art

A bolt is a mechanical part, a cylindrical threaded fastener that is matched with a nut. It is a type of fastener consisting of a head nut and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten and connect two parts with through holes.

Many existing portable bolt production welding machines are just common welding machines with mobile bases to move to designated locations to repair bolts. However, when welding bolts with common welding machines, it is usually necessary to manually hold the nut and the screw before welding. This will cause inaccurate welding positions, which not only affects the quality of the bolts after welding, but also reduces work efficiency.
