The purpose of telltale /venthole/weephole is not related to weld intersection.
It has nothing to do with weld intersection.

Tell tale holes/vent holes are provided vent out the gases that developed during welding of pad plate to nozzles/shell.
It’s threaded and can be used for pressure testing(pneumatic testing) of pad plates.

@Hieu_Thai, ventholes normally specify 6 mm NPT, it may be closed after hydrotest or seal by silicon.
If not specified in drawing, no need to do.

As my answer, chamfer or round the edges find in detail drawings.
