Hey all, Not sure if things like this are dealt with here, but I'll give it a shot: I have a pipe with an outer "diameter A" (small) and a flange with an inner "diameter B" (large). Between them is a conical transition piece with the following characteristics: The OD of the cone at the small end is equal to the OD of the pipe; The ID of the cone at the large end is equal to the ID of the flange. This transition piece needs to be welded to the other two pieces. The ends of the conical piece are not machined, so the groove for groove welding is already there. The locations to which the arrows point in image are the locations of the welds: The one at the top needs to have a smooth contour, flush with the cone below and the pipe above; The one on the bottom also needs to have a smooth contour, flush with the cone on top and flush with the flange on the bottom; Both of these welds need an extra weld on the opposite side, ground down to create a smooth transition where there would otherwise be a sharp edge (thus, both opposite-side welds should be fillet welds with a smooth contour). Are the welding symbols/sizes I included correct (assuming roughly 1/8" thick sheet metal)? Groove weld, ground flush (G for grinding), with a fillet weld on the opposite side, ground to a concave shape.
