Professional Ultrasonic Welding Stress Relief Equipment

Professional Ultrasonic Welding Stress Relief Equipment

Description: 

The professional ultrasonic welding stress relief equipment is a digital intelligent ultrasonic system that can eliminate the internal stress and weld toe surface defects generated by the welding process. Prevent deformation or cracking of the workpiece caused by stress release and suppress crack initiation. Improve the yield strength and fatigue life of welds, and increase surface hardness.

Principle: 

The driving power of ultrasonic waves is connected to the ultrasonic transducer set in the housing through a cable. The vibration output end of the transducer is connected to the amplitude rod, and the amplitude rod end is equipped with an impact needle.
The ultrasonic driving power supply can convert the mains power into high-frequency and high-voltage AC power, which is transmitted to the transducer. Then, the ultrasonic transducer converts the current into mechanical energy, that is, ultrasonic waves. Its manifestation is that the transducer performs reciprocating expansion and contraction motion in the longitudinal direction, and the frequency of the expansion and contraction motion is equivalent to the frequency of the AC current of the driving power supply. The displacement of the expansion and contraction is about ten micrometers.
The function of the amplitude lever is to amplify the output amplitude of the transducer, which can reach about 100 microns, and to apply impact force to the impact needle, pushing it forward at high speed. After the impact needle impacts the workpiece, energy is transmitted to the weld seam to eliminate stress.
After being subjected to the reaction of the workpiece, the impact head rebounds and hits the high-frequency vibration amplitude rod. It is then excited again and collides with the weld seam at high speed, repeating this process multiple times to complete the impact work.

Parameters:

Application : 

Industries that have strict requirements for the stability and strength of welding joints. For example, metal welding treatment in industries such as bridges, electricity, shipbuilding, pressure vessels, and steel structures.
