Abstract

The invention discloses a steel stud and thick aluminum plate frictional stud welding method, which is characterized in that the welding end part of a steel stud is subjected to certain structural design, the steel stud is rotated, is applied with frictional acting force, and is contacted and rubbed with an aluminum plate, and the steel stud is slowly embedded into the thick aluminum plate. Double characteristics of frictional stud welding and threaded connection are realized, so that a welded joint with good performance is manufactured. By the method, steel studs with middle and small diameters are welded with thick aluminum plates. According to the method, the welding strength of the stud welding can be obviously improved, the influence of defects in common welding on the joint quality is reduced, and the service life is greatly prolonged.

Description

technical field

[0001] The invention relates to a stud welding method, in particular to a friction stud welding method between a steel stud and a thick aluminum plate, which is suitable for welding between a steel stud and an aluminum plate, especially for welding between a medium and small diameter stud and a thick aluminum plate welding. Background technique

[0002] Stud welding refers to a method of welding studs or similar metal posts and other fasteners to metal substrates. As a simple, high-speed, low-consumption, and low-pollution advanced welding technology, stud welding is widely used in the fields of vehicles, shipbuilding, boilers, steel structures, construction, electronics, instruments, and medical equipment. According to the heat source classification of stud welding, stud welding can be divided into welding methods such as resistance welding, friction welding, explosive welding and arc welding. According to the classification of stud welding power source,...
