Technical Field

In particular, the door structural member of the new energy automobile mainly comprises an aluminum alloy member, and residual stress is inevitably generated after welding, and is an important cause of deformation or cracking of the door structural member. After the welding is completed, the door structural member must be subjected to an aging treatment for eliminating residual stress. Vibration aging is a relatively ideal treatment method for effectively eliminating residual stress.
In addition to post-welding vibration aging treatment, the control of welding quality in the vehicle door manufacturing and forming process can also introduce a vibration welding process in the welding process to avoid or reduce welding defects and improve the welding quality and the mechanical properties of the joint. Vibration welding has proven to be an effective method of improving the fatigue life of welded parts.
Vibration welding and vibration aging are technical processes adopted in two stages respectively for improving the quality of welding seams.
