From the general state of the art, it is known that higher frequency hammering can cause an increase in the life of mechanical components and equipment. Thus, in dynamically loaded constructions an improved fatigue life or fatigue life has been found. By superimposing residual tensile stresses with compressive stresses on the material surface, the cause of stress corrosion cracking is reduced or avoided. Likewise, there is a reduction in shrinkage stresses and hence distortion due to the hammering of each layer of welds. Such a device is shown for example in WO 2009/003790 A1.

  • DE 3402010 A1 describes a working device which should substantially facilitate the work of removing rust from iron plates and other iron structures. Rust is removed with the help of a few small hammers, which are parallel, and knock against the surface from which rust is to be removed.
