High Power Ultrasonic Residual Stress Elimination Impact Equipment

Description: 

High power ultrasonic residual stress relief impact equipment is a new post weld treatment technology developed domestically and internationally in recent years. It can completely eliminate welding defects such as incomplete fusion, undercutting, and micro pores at the weld toe, as well as eliminate tensile residual stress, generate compressive residual stress, refine grain size, significantly increase the fatigue life of welding structures, and prevent weld cracking.
High power ultrasonic residual stress relief impact equipment is mainly used in industries with strict requirements for the stability and strength of welding joints. For example: bridges, electricity; Shipbuilding; Metal welding, welding seams, and post weld treatment in industries such as pressure vessels, steel structures, and wind turbines.

Parameters:

Advantages :

1. Transform the residual tensile stress in the surface layer of the metal weld into compressive stress, thereby significantly improving the fatigue life of the metal structure
2. Change the metal grain structure within the surface layer to create a deformation layer, thereby significantly improving the strength and hardness of the metal surface layer
3. Improve the geometric shape of the weld toe and reduce stress concentration.
4. Changing the welding stress field significantly reduces welding deformation and improves the dimensional stability of the workpiece.
