Weld overlay deflection estimate
Weld overlay deflection estimate
(OP)
I was wondering if anyone has a general calculation for the expected deflection (caused by weld shrinkage) of a circular disk that has a weld overlay applied to it?

Weld overlay deflection estimate

RE: Weld overlay deflection estimate
However, as always when treating weld distortions, the main problem is with determining the differential elongation of the two materials, that depends on so many parameters (weld speed, overlay thickness, width of each pass, preheat, and so many others...)

RE: Weld overlay deflection estimate
Thanks for the help. I have looked at that formula in roark already. My question came from all the other factors you mentioned. I was hoping for something with a heat input factor, volume of weld deposited, or simplified general equation with a "fudge factor". I'm not sure an approach with a delta T in it would work (like roark) since the temperature is not known as the weld is being deposited and it is constantly changing as more volume of weld is added. Maybe someone knows of a "rule of thumb" approach...

Sounds like it would be very difficult to predict, even if anyone had derived such a formula.
