Welding stress refers to the internal stress within the welded workpiece caused by the welding process. It can be categorized into two types based on the time of its occurrence: welding instantaneous stress and welding residual stress. Welding instantaneous stress varies with temperature changes during the welding process; welding residual stress, on the other hand, is the stress that remains after the workpiece cools down to its initial temperature. Depending on the direction within the workpiece, welding stress can be classified into longitudinal stress, transverse stress, and thickness stress. In reality, welding stress is a three-dimensional stress, but for thin plates, the thickness stress is relatively minor and can be treated as a two-dimensional stress.

The greater the temperature difference on the component, the higher the residual stress from welding. Preheating the component before welding can reduce the temperature difference and slow down the cooling rate, both of which can decrease the residual welding stress. Preheating is often used to reduce stress during the welding of alloys (excluding Austenitic stainless steel), thick plates, and rigid components. If it is difficult to preheat the entire component, local preheating can be used, which involves heating the area around the weld and at least 80mm on either side. Narrow heating zones can cause new temperature difference stresses.

Process of vibration treatment method development
Vibration treatment involves supporting the component with the appropriate elastic material, with the support position being as close as possible to the resonance frequency of the component.
At the joint line. Then rigidly secure the vibration exciter at a position slightly away from the joint line and connect it to the control system. Adjust the vibration force.
Grade, it is advisable to start in a small position. According to preliminary estimation or experience, identify some points with higher dynamic stress and grind them.
Attach the strain gauge to the dynamic strain gauge. Sand at points with high residual stress, and use X-ray or magnetic methods.
Measure the residual stress values before vibration treatment using the stress method. That's the trial vibration for the vibration aging process.
After completing the above preparatory work, proceed with the selection of parameters for the vibration treatment process: turn on the controller switch, making
Vibrator is at speed, turn on the recorder, dynamic strain gauge, and other instrument switches. Gradually adjust the frequency dial of the vibrator.
Button (or Auto-Tune button), while observing the curve drawn on the recorder. When resonance occurs in the component, the amplitude
A frequency peak will occur, and the dynamic stress curve will also exhibit a quantity. Sweep the frequency up to the controller's rated frequency.
At the given rate, the curve shows the number of resonant occurrences and their respective resonant frequencies that the component can exhibit within the permissible range of the equipment.
The value of dynamic stress in resonance.
While resonating, pay attention to observing the vibration mode of the components to adjust the support position to the joint line, which can be done again after shutdown.
When adjusting the position of the vibration exciter to achieve the desired amplitude of the components, this process needs to be repeated multiple times.Further according to the dynamic stress
Adjust the amplitude level of the vibration exciter based on test results and experience data.
Support point position and exciter excitation force level adjusted, then begin vibration aging process treatment, control
Adjust the instrument to resonate with the resonant frequency of the component, while simultaneously measuring the time-amplitude curve to observe the relaxation of the vibration.
The effect. After 30 minutes of processing, the amplitude-time curve flattens. At this point, reduce the frequency back to the initial frequency and then proceed.
Bifrequency characteristic scanning allows for two amplitude-frequency characteristic curves to be obtained on the same recording paper. The distinction between the two curves is:
Resonant frequency decreases, resonance peak shifts to the left, and peak value increases.
