Ultrasonic stress relief of very large components

Ultrasonic stress relief can be used for very big and heavy metal parts and metal constructions.  We can avoid heat treatment and make it fast, without spending a lot of energy on thermal cycling. Very big metal parts usually cannot be treated thermally since it's impractical to find sufficiently big ovens, or to use the huge amount of energy to heat them.

In the movie files below, water has been placed on the vibrating surfaces to visualize the acoustic activity and MMM vibrations. Water spray is also indirectly visualizing stress relief and the descaling process.

For agitating very large metal parts it will be necessary to use several ultrasonic MMM agitators, as shown in the following videos.
