Restoring Dished Head knuckle thickness
Restoring Dished Head knuckle thickness
(OP)
As per UW-42, is it permissible to restore a dished head thickness falling below the minimum required thickness?
One of my fabricator has deposited the welding as per UW-42 onknucle of an ellipsoidal head The min req. thickness was 10mm, but observed was 9.6mm.
Any input would be highly appreciated.
Thanks

Is there a tolerance on the 10mm ? +/- .5mm, if you are lucky.

Construction in which deposits of weld metal are applied to the surface of base metal for the purpose of restoring the thickness of the base metal for strength consideration; or modifying the configuration of weld joints in order to provide the tapered transition requirements...
Whic one of these cases would my case fall under according to you?

Your situation is restoration of thickness for strength consideration. When I made heads we did this multiple times successfully, always with the customer's approval as well as our AI's, even when the heads were seamless.
