Abstract

The vibration welding technology of the present invention includes: 1. connecting a vibration exciter rigidly to the welded part or a vibration table with the welded part, and regulating the exciting force of the vibration exciter in resonant state to make the welded part obtain required amplitude; 2. maintaining the welded part in resonant state and in stable amplitude; 3. selecting one relatively low work frequency in resonant state and with amplitude not greater than one third of the resonant amplitude; 4. picking up the vibration with one acceleration sensor fixed in certain distance to the welding seam and shifting with the welder for tracking and monitoring the vibration parameters; etc. The present invention has convenient welding operation, high welding effect and high welding speed, and is suitable for welding different kinds of member.

Description

technical field

[0001] The present invention relates to welding technology, and further refers to improved vibration welding technology. Background technique

[0002] Vibration welding refers to a welding method in which the workpiece is vibrated while welding in the process of welding steel parts. This method can eliminate the internal stress of the welding layer and the welding deformation and cracks (hidden cracks) produced during the welding process, reduce slag pores and pores, increase more and healthier effective crystallization nuclei in the weld pool, refine the grains, Prevent jump welding, improve welding quality and material mechanical properties and fatigue life.

[0003] However, in the vibration welding process of the prior art, the amplitude is controlled by adjusting the frequency. When the quality of the exciter is constant, it is difficult to obtain a predetermined amplitude by adjusting the frequency for large welded components; This process uses multip...
