Head to shell weld - missmatch on ID or OD
Head to shell weld - missmatch on ID or OD
(OP)
I have a supplier who wants to weld the head (10mm thick) to the cylindrical shell (8mm thick) of a vessel he is making for us by matching the outside diameters of the head and shell.
This will give a miss-match at the internal diameter / root of the weld.
Is there any rule about this ?
I would think that you would not want a miss-match at the root and that at the outside diameter such a miss-match doesn't really matter as it will be taken out by the weld seam.

The short answer is to grind a taper onto the thicker member with a minimum of a 3:1 transition between the thicker and thinner components.
