HFMI Toe Peening
3x to 10x increase in Fatigue Life
40% Increase in Fatigue Strength
More effective weld repairs with greater MTBF and less issues with re-cracking
Inter-Run Peening for Residual Stress Control
Two butt welds welded using identical parameters. The bottom plate had inter-run peening. Note the lack of distortion
Weld Cap and Surface Peening
The weld cap can be peened to impart residual compressive stresses to improve fatigue performance.
Edge Peening
Produce a smoothly rounded corner with residual compressive stresses to massively increase the fatigue life and reduce cracking from edges of plate.
