Heavy Equipment FAQs on Laser Peening

  • The time to process a part depends on the number of pulses required to cover the area to be treated. This may range from a few seconds to a few hours depending upon the complexity of the part and the size of the treatment area.

  • Laser peening does not appreciably alter the part surface finish. Laser peening is a mechanical hardening process (not a thermal one) and the opaque overlay prevents surface melting and other heat effects. The treated surface may develop a slight wavy appearance from the pulsed laser spots, although the depressions are typically only a few microns deep. Any visible indications of laser peening can be removed post processing without affecting the compressive residual surface stresses.

  • Yes, laser peening can be applied to fielded parts to extend their operational service life. Laser peening around existing cracks inhibits further propagation, and can return the fatigue tolerance of damaged parts to like-new condition.
