[MW:26821] Weld overlay shrinkage calculation.

Dear Members,

I  would like to know how to calculate the weld overlay shrinkage. For eg. We are performing a weld overlay of SS 347 on SA-387 11 2 plates with an ESW process. The weld overlay will be done after the plate is rolled. The ID of the plate is 2500mm. So what shall be the rolled ID prior to weld overlay so that after weld overlay the ID shall not be less than 2500. If its slightly bigger that would be acceptable but should not be too big else we shall waste time and material.

Could someone guide me to know the formula for the weld shrinkage of the weld overlay.

Thanks and Regards
