Hi guys,
I'm peening a HPC vane with a indexing machine. Higher intensities required on the root and shroud portion (10-13N) , the blade portion requires 4-7N. The root and shroud portions are peened using fixed guns at a higher pressure while the blade body itself is peened at a lower pressure using vertical motion guns,. No maskings are to be used. There is a tendency for the vertical motion guns to sweep hit the root and shrouds as well at low pressures after
I m thinking that I should hit the higher intensity portions first at higher pressure followed by sweeping the blade body at lower pressure. My question is
1)Should I do it the other way round or does it matter at all?
2)If a part is peened at high pressure and then is peened again at lower pressures, Would the intensity remain the same if things were done the other way round
