Dear Mr. Jack Champaigne,
I have got your reference from the website
www.shotpeening.org. I am a welding engineer.
I am faced with a unusual query for which I am not able to find a satisfactory solution.
One of our clients has requested "Shot peening" of restrained joints during welding of assembly.
It is left to me to identify the restrained joints and decide the thickness on which I shall have to do peening.
I have to submit documented proof before I can decide which joints shall be peened and which joints will not require peening.
The job has mainly fillet joints, Butt welds and Single bevel joints. the Butt and Single bevel joints are Ultrasonically tested and the fillet joints are tested by performing Dye Penetrant test only.
my question is as follows
1) What is the basis for deciding the weld thickness of joints to be peened?
2) Should all plate thicknesses be peened while welding multiple pass fillet joints?
I will be grateful if you can spare the time to answer my query.
