For structural steel, a good starting point, in my humble opinion, would be Table 6.1 and Table 9.16 of AWS D1.1 Structural Welding Code- Steel. These tables show the visual acceptance criteria for welds. Also, Aisc 360 Specification for Structural Steel Buildings, Chapter N Quality Control and Quality Assurance, which includes three tables... One for inspection tasks prior to welding, one for inspection tasks during welding, and one for inspection tasks after welding.
There are also a good bit of visual aids... power points that depict weld discontinuities online that I've found to be very helpful teaching aids.
