Home Forums General Discussion Shot Peening Process, Intensity, Coverage Non-constrained Almen strips

Jack,
I have questions about use of the Almen holder.

Our parts are about dime size or smaller. They are .050 inch thick – They react differently(less intensity) to the shot impacts then the "A" Almen strip mounted on a heavy steel backer block (Almen holder). We demonstrate this by using 2 Almen strips bolted back to back with no holder block – these saturate at a lower arc height compared to strips mounted on holder blocks.

Is this (Back to Back Almen strip fixturing – tumbling freely within the load of parts ) a legitimate measuring method of peening intensity ?

Thanks,
