Where you see it
Plate and pipe butt joints welded from one side, from piping spools to pressure vessel shells and structural splices.
What is written next to it
On the welding symbol, the V groove weld carries the groove depth and effective throat to the left, the root opening inside the symbol and the groove angle, for example 60°, beside it.
How it is inspected
Inspection of a V groove weld usually covers visual inspection, then radiography or ultrasonic testing of the full-penetration weld where the code or the drawing calls for it. Each inspection is recorded against the weld, so the joint can be signed off with its evidence. See the ITR guide.
