đ Key Concepts
⢠Basic weld symbols used on the reference line (fillet, groove, plug, slot, etc.)
⢠Difference between groove type symbols and finish/contour symbols on welding drawings
⢠How an inverted âVâ shape is used in standard welding symbol charts (AWS A2.4)
đ Think About
⢠Look at where the inverted âVâ appears: is it on the reference line as the basic weld symbol, or as a small symbol above/beside it? What does that position usually represent?
⢠Compare the illustrationâs joint preparation (angle, root opening, root face) with common groove types â which groove shape matches that geometry?
⢠Ask yourself whether anything in the figure actually shows surface finishing or back gouging operations, or if it is only describing joint preparation and groove shape.

Before You Answer
⢠Confirm from a weld-symbol chart what the inverted âVâ basic weld symbol represents when placed directly on the reference line.
⢠Check whether surface finish symbols (like grind, machine, chip) look like a âVâ or use different letters/shapes.
⢠Verify that the dimensions given (60° min, root opening and root face) correspond to the geometry of a specific groove weld type, not to a finishing operation.
