This course covers the theoretical and practical aspects of Flapper Peening. The participants will learn the basis of shot peening and the specifics related to flapper peening. In the practical session, the participants will use a FlapSpeed® PRO 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 will provide a Certificate of Achievement.
