“Formula 62” Vibratory Stress Relief Equipment
Stress Relief Engineering Company from Costa Mesa, California, has served the metalworking community since 1962, and is the world leader in vibrational stress relief technology. After four years of X-Ray Diffraction studies, SRE commercially introduced the process in the U.S. in 1962. This process is now used worldwide throughout the manufacturing and fabricating community.
Residual stresses are hard to visualize, difficult to measure, and extremely difficult to calculate or predict, yet they are just as important in the function of a part as are externally applied forces that are more easily measured and calculated. Residual stresses are fundamentally introduced into the material in one or more of the following ways: thermal, metallurgical, mechanical and chemical. Since these are the processes that make up our metalworking trades, it is only right to assume that, at some point of time, a stress relief treatment may be required.
The Formula 62 method uses low frequency vibrations to reduce peak residual stresses and restore equilibrium to the atomic structure with results comparable to costly thermal stress relief. Reducing residual stress eliminates dimensional instability and increases yield without reducing fatigue life.
Test results illustrate the effect which Formula 62 vibratory stresses have on reducing residual stress due to welding.
SRE vibratory stress relief equipment provides portable, low-power systems for in-plant or field use.
