      Aging equipment and its recommended use of Sigmar VSR process of scientific tests on the 316L stainless steel plate (440 × 550 × 40mm3) and the A022 electrode experiments.  The Chinese Academy of Sciences Institute for Metals Research on residual stress test, the following conclusions: 
1. Examination of the original plate welding stress values higher near the material yield point (the vertical is about 320Mpa, horizontal about 230Mpa). 
2. Using vibration welding process, so that test plate welding stress significantly decreased (vertical about 90Mpa, horizontal about 100Mpa).
3. Vibration Welding later after VSR treatment, little change in stress (vertical about 70Mpa, horizontal about 86Mpa). 
The vibration welding of the main products were also tested and the results achieved similar results.
