Weld Shrinkage

[KentCaudill]

Who among you can comment on the amount of weld shrinkage to be encountered in welding large diameter segmented T316L SE pressure vessel heads? The heads are 38'Ø with a minimum thicknes of 1.125" and are fabricated from 13 segments. Do you know of any articles or studies addressing this issue? Please feel free to pass my request along to others if you wish.

Thanks for your help, Kent.

With the amount of welding , fabrication and all the expense that goes with it, I wouldn`t rely on guess work . A mock up of the joint configuration (gap size) material and welding process is the best and safest way to go. A precise before and after measurement will tell the story.
