Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a handheld automated stud welding gun. Background Technology

[0002] Stud welding is a method of welding where one end of a stud is brought into contact with the surface of a plate (or pipe), an electric arc is ignited, and after the contact surface melts, pressure is applied to the stud to complete the welding. Due to its advantages of speed, reliability, simplicity, and low cost, stud welding can replace riveting, drilling, manual arc welding, and brazing. It can weld metals such as carbon steel, stainless steel, aluminum, copper, and their alloys, and is now widely used in the automotive, shipbuilding, industrial plant construction, highways, railways, bridges, towers, energy, airports, stations, power plants, pipe supports, hoisting machinery, sheet metal engineering, electronic switchgear, medical equipment, food industry, home appliance industry, and telecommunications engineering fields.

This method is inefficient and significantly increases worker workload, especially for batch welding. Therefore, there is a need for a stud welding torch that can solve these problems. Furthermore, it is crucial to ensure both high success rates and efficiency in welding. Consequently, the development of a new generation of stud welding torches has become an important part of the welding technology field. Utility Model Content
