Report on process simulation and validation - January 2026

The Soni-Shape-Laser project has successfully completed half the project (of 2 years) including all the simulation program, with the ultra-sonic excitation and the beam shaping variations. Some encouraging results were found with the 20kHz frequency when placed just 90mm away from the weld. The EBSD analysis ( to the left of each diagram) shows marked improvement to the grain structure of the weld when welded with the ultrasound as mentioned. The simulation pattern (to the right) of the diagram shows the temperature variations live in the weld and how the ultrasound changes the fluid flow from the baseline example. A paper has been written and will be published after reviewing later this spring 2026.
