Home Forums General Discussion Shot Peening Process, Intensity, Coverage Intensity and Coverage of Shot Peening

Mr. Champaigne
I have two questions?
1. If the MIL-S-13165 is now SAE spec AMS-S-13165
But our customer drawings still show their drawings to be MIL-S-13165 is this still ok to use?
2. We are having problems qualifying our machine with our current parameters (.008-.010 intensity). Nothing has changed as far as material specs and shot. We have always qualified our machine with the parameters that have been used for the past 20yrs. I know that the flow meter does not work and I have stressed to the maintenance department to have this flow meter fixed. The machine parameters have been changed to get the machine to qualify. Do you have any suggestions?

Parameters Changed: Orifice plate was 3/16 opened up to 3/8
Lance setting was backed away by 1.25”
Pressure was 50psi +-5 changed to 80psi
12 IPM changed to 6 IMP

Your help is greatly appreciated.
