BAT Vibratory Stress Relieving Services

Vibratory Stress Relief (VSR) and Thermal Stress Relief (TSR) both reduce residual stress and mitigate
it’s consequences. Rising fuel costs coupled with ecological concerns will lead to a need to re-evaluate
manufacturing processes which use large amounts of energy. One such is the TSR process that is
widely used to reduce or modify the internal or residual stresses in parts that are introduced by other
manufacturing procedures such as fabrication, machining, or assembly. The TSR process is typically
done in large furnaces and is fuel intensive. The large consumption of energy, the thermal influence
and air pollution affects on the environment coupled with rising costs are the biggest concerns of this
process. As an alternative to the TSR, VSR has the advantages of low energy consumption and dramatic
reduction of pollution to the environment and is increasingly economic.

1. VSR is a fairly rapid process and does not cause the delays often associated with TSR.

2. VSR does not have any associated transport costs as we offer an on site service.

3. VSR can be easily used on components employing various metal types in their construction.

4. VSR does not cause scaling or damage to coatings.

5. VSR does not bring about undesirable metallurgical changes such as grain growth and overaging.

6. VSR does not affect material properties such as wear resistance, hardness and yield strength.

7. VSR can be used to treat components of any size (Approx. 10 kg to 150 tons)
