Ultrasonic Impact Equipment - In Stock with Superior Quality

Basic Principle of Ultrasonic Welding Stress Relief Equipment
The basic principle of ultrasonic welding stress relief equipment is to use high-power ultrasonic waves to propel impact tools that strike the surface of metal objects at a frequency of over 20,000 times per second. Due to the high energy of the ultrasonic waves and focusing, it induces significant compressive plastic deformation on the metal surface; at the same time, the ultrasonic welding stress relief equipment alters the original stress field, generating a certain amount of compressive stress, and strengthens the impacted area.
The ultrasonic welding stress relief equipment significantly enhances the fatigue strength of metal weld joints and structures, dramatically extending their fatigue life; it eliminates residual tensile stress and induces compressive stress in the impacted areas, thereby improving the load-bearing capacity of the workpiece. It effectively improves the geometric shape of weld toes, drastically reducing the stress concentration coefficient at the weld toes, outperforming TIG welding processes. It removes surface micro-cracks and welding defects at the weld toes, suppressing early crack initiation; it strengthens the surface of metal parts, enhancing surface quality and service life. The equipment is energy-efficient, pollution-free, easy to use, and is not restricted by the shape of the workpiece, the site, or the environment, offering remarkable treatment effects.
Ultrasonic Stress Relieving Machine Applications
Ultrasonic impact products have also been developed into a series, widely applicable in fields such as shipbuilding, petrochemicals, railways, wind turbine generators, steel or composite material bridges, heavy lifting equipment, etc. They are suitable for post-weld treatment of material welding structures to extend the fatigue life of the焊接 structures and enhance their fatigue strength. Additionally, they can significantly reduce stresses and residual stresses during the welding process, particularly suitable for post-weld treatment of structures like general joints, load-bearing joints, and dissimilar material welding joints.
Ultrasonic impact stress-relieving equipment enhances the fatigue strength of metal weld joints and structures, significantly extending their fatigue life; reduces residual tensile stress, creating compressive stress in the impacted areas to improve the workpiece's load-bearing capacity; effectively improves the geometric shape of weld toes, lowering the stress concentration factor at the toes, with good results; reduces surface cracks and welding defects at the weld toes, inhibiting early crack initiation; strengthens the surface of metal parts, improving surface quality and service life. The equipment is efficient, energy-saving, pollution-free, and easy to use, without restrictions on workpiece shape, site, or environment.
Ultrasonic Stress Relief Equipment Processing Effect
Extensive experimental data shows that ultrasonic impact can increase the fatigue strength of steel welding joints by 60~180%, extending their fatigue life by 10~13 years; and can enhance the fatigue strength of aluminum and titanium alloy welding joints by 26~48%, extending their fatigue life by 5~4 years.
