The WIAP MEMV process requires over 400x less
energy than the standard stress relief annealing.
This is nice proof of how much industry can do much to reduce CO2 emissions.

2014, the company WIAP AG Ltd SA has applied for six new patents for the
“vibration stress relief on metal” (MEMV®) technology. The last one in
2019. The innovative procedure is utilised in order to reduce stresses in
metallic components once again, e.g. the distortion as a consequence of welding
processing operations. Customary techniques such as stress relief annealing are
also applied to such tasks but are mostly energy-intensive or lead to the
scaling of the components. In this respect, the MEMV® technology offers a few
advantages for the user.
company WIAP AG has already been successfully dealing with the “vibration stress
relief on metal” technology for a long time. Meanwhile, the supply programme has
been comprehensively extended to five basic models: V5 for components with
masses up to 5 t, V20 (for 20 t), V50 (50 t), V100 (100 t) as well as V200 for a
workpiece weight of 200 t. Moreover, the new developments encompass the
multiaxial VS vibrator. This is suitable particularly for welded structures
since it can excite all three coordinate directions (X, Y and Z axes) with just
one device. Therefore, the multiaxial vibrator is simultaneously used for
welding while the component is vibrating. Since it excites all the axial
directions, decisively better stress distributions than with conventional
biaxial exciters are thus possible with it.
