NEEDLE PEENING TRAINING – SPIKER®

This course covers the theoretical and practical aspects of Needle Peening with the Spiker®. The participants will learn the basis of shot peening and the specifics related to Needle peening. In the practical session, the participants will use a Spiker® tool to gain hands-on experience with the process while generating a saturation curve. A written exam is given to the participants and a passing grade of 70% will provide a Certificate of Achievement.
