Welding stress relief equipmentIt is used to eliminate welding stress and can replace aging methods such as heat treatment and vibration aging. The treatment process is simple, and the effect is stable and reliable. Using high-power energy to drive impact tools to impact the surface of metal objects at a frequency of over 20000 times per second, due to the two major energies of high frequency, high efficiency, and focusing, the metal surface undergoes significant compressive plastic deformation; At the same time, the shock wave can change the original stress field and generate a certain numerical compressive stress; And strengthen the impacted area.

　　

The use of welding stress relief equipment can achieve the following effects:

　　

1. Eliminate the welding tensile stress of the weld seam and preset a certain value of compressive stress;

　　

2. Eliminate welding defects at the weld toe and form a circular arc transition to reduce stress concentration factor;

　　

3. Refine the grain size at the weld toe;

　　

4. Prevent weld cracking;

　　

5. Improve the fatigue strength and fatigue life of welded joints;

　　

6. Improve the stress corrosion resistance of welded joints.

　　

The welding stress relief equipment is easy to use, requiring only 4 buttons for operation, making it easy to grasp the essentials in a short period of time. High definition LCD screen displays the dynamic curve of stress changes during aging at any time. The usage functions include: fully automatic, semi-automatic, and manual integrated operation program, with complete functions. Automatically scan the frequency, confirm whether the timeliness processing effect is appropriate, and provide a revision plan. If there is an abnormal form of the device during operation, the device can automatically determine and provide the correct usage method. Adopting mature pulse width modulation technology, the aging processing point is automatically selected during aging processing, and the changes in curve data are displayed on the LCD screen for real-time monitoring. The time processing result curve is merged and displayed for easy observation of various data.

　　

The fault analysis function of welding stress relief equipment includes issues such as current overload, voltage overload, speed and frequency signal failure, circuit connection, etc. The LCD screen will provide clear solutions to the problems, making it convenient to use. High speed thermal printer, capable of printing curve data for easy archiving. Adopting high-power anti vibration permanent magnet slotless DC motor with adjustable eccentricity and no poles. The device has a small size and can be moved to a location for use at any time, making it extremely convenient to use.
