When contouring an angle beam wedge for a convex surface, an undesirable result of a wedge which is contoured too well might be:

Greater beam divergence due to larger contact area

Production of unwanted surface waves

Lower beam divergence due to larger contact area

Overly efficient coupling of sound beam into test part
