Ultrasonic Stress Strengthening Welding Equipment Alternative Aging Methods Such as Heat Treatment

Description:

Ultrasonic stress strengthening welding equipment is mainly used to remove internal stresses and surface defects of weld toes generated by welding processes; 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

Through experiments, it has been proven that the stress removal rate of workpieces treated with ultrasonic stress strengthening welding equipment can reach over 80%, completely improving the deformation phenomenon caused by stress concentration and increasing the fatigue life by an order of magnitude.

Parameters:

Main Purpose:

1. Eliminate residual stress after welding
Welded joints usually have significant residual tensile stress, which can lead to a decrease in structural load-bearing strength, and even cause the joint to crack due to excessive tensile stress during welding. Ultrasonic impact treatment can easily increase the compressive stress of metals, which can eliminate residual tensile stress after welding and increase beneficial compressive stress when processing welds.
2. Extending the lifespan of welded structures and gear structures
There are a large number of welded joints in offshore oil platforms, engineering machinery, transportation equipment, etc. Welded joints are weak points, and more than 90% of structural fractures originate from welded joints. The ultrasonic impact machine significantly reduces the stress concentration factor by treating the weld toe on the weld seam, while enhancing the comprehensive mechanical properties at the weld toe, and improving the fatigue life of the welded structure by more than 10-100 times.
3. Surface strengthening and stress corrosion resistance
Commonly used for storing corrosive media such as acidic and alkaline solutions, petroleum, and chemical raw materials. The welding joint area on the storage tank is the most susceptible to corrosion as a weak point. By using ultrasonic impact to fully cover the weld seam and the heat affected zone on both sides, the comprehensive mechanical properties of the surface are improved, and compressive residual stress is generated on the surface, eliminating the conditions for stress corrosion and greatly improving the stress corrosion resistance of the storage tank.
