The beneficial effect of the utility model is:
1. vibration can make grain refinement in the welding crystallization process, therefore the weld material mechanical property is significantly improved, and yield limit σ S, the strength degree σ b of material all can improve 10%～30%, and this helps to prevent the generation of HOT CRACK FOR WELDING P and cold crack.
2. reduce welding residual stress more than 30%, this helps to prevent or reduces in the welded unit use crackle takes place, and increases the service life the dimensional accuracy of stabilizing member.
3. reduce welding deformation more than 30%,, reach designing requirement if adopt " giving stiffness method " and " giving stress method " then be out of shape and reduce more than 60%.
4. because the reduction of grain refinement and residual stress has improved welding seam breaking toughness more than 20%, improved the ability of weld material cracking resistance greatly.
5. improve fatigue limit more than 15%, improve the weld fatigue life-span more than 70%.This is the integrated value of various effects, and this also is the final goal that various additional process is pursued to improve service life.
6. reduce sand holes, skip welding etc., welding is had a fine grain, reduce the stress of root and concentrate, significantly improve welding quality and operating efficiency.
7. can exempt welding and give thermal process or hot temperature is given in reduction.
8. can exempt the heat aging or the oscillating aging of postwelding handles.
9. prevent significantly or reduce weld crack.
