(OP)
Radially chamfering stiffener edges instead of a diagonal cut (where you have the fillet weld on the supporting beam.) This is done for seal welding. Why is this usually specified, often by oil & gas firms?

RE: Radially chamfering stiffner edges instead of a diagonal cut

I think that this stems from the standard Nautical details for metal ships due to brittle fracture concerns in areas of stress concentrations.  You see similar details a lot on ferries in the stiffener connections to the deck plate.  There is a lot of continuous vibration on nautical vessels that is not usually a characteristic of land based structures.

We learned a lot about steel detailing from the old Liberty ships...
