Product Application

Ultrasonic stress relief equipment is widely used in such fields as ships, petrochemicals, aviation, railways, wind turbines, steel or composite bridges, and heavy lifting machinery. It is suitable for the residual stress elimination of welding structures of various materials. It can prolong the fatigue life and increase the fatigue strength of welded steel structure, and can eliminate the welding process stress and residual stress. It is especially suitable for the welding stress treatment of ordinary joints, bearing joints, and heterogeneous materials welding joints.

Ultrasonic welding stress elimination equipment is mainly used to eliminate the internal stress generated by the welding process, welding toe surface defects. Prevent deformation or cracking of workpiece caused by stress release and inhibit crack initiation. Improve the yield strength and fatigue life of weld and increase surface hardness. After a long period of practice, it has been proved that after the ultrasonic shock gun treatment of the workpiece, the stress elimination rate can reach 80 or more, completely improving the workpiece due to stress concentration caused by deformation. The fatigue life can also increase by an order of magnitude.

Ultrasonic impact equipment is the use of high-power ultrasound impact on the surface of a metal object. Due to the high frequency ultrasonic wave, high-efficiency focusing energy, the metal surface produces a large compressive plastic deformation. The fatigue life and fatigue strength of welded joint can be improved significantly. After welding, the structure parts use an ultrasonic impactor to impact the welded toe area to smooth the transition, thereby reducing stress concentration, eliminating defects on the welded toe surface and generating greater compression plastic deformation at the welded toe, resulting in residual compression. stress, Kohai ultrasound adjusted the residual stress field of welding and strengthened and hardened the welds. As a post-welding treatment device, the ultrasonic impact device can simultaneously improve multiple factors that affect the weld quality, such as stress, defect, welding toe geometry, surface reinforcement, etc., so it has the effect of improving the fatigue performance of welded joints. The fatigue strength of the treated welded joint can be increased by 80 % -200 %, and the fatigue life can be extended by 5-100 times. Due to the use of ultrasonic welding stress elimination equipment, the traditional grinding and slag removal processes were eliminated, saving more than 60 % of the working time, reducing the intensity of manual labor, and greatly improving the production efficiency of operations.
