: The PDF outlines exactly what to look for—cracks, surface pores, or undercuts. For instance, an undercut might be limited to a fraction of a millimeter depending on the base metal thickness. Visual testing is not a single event at

ISO 17637 explicitly states that the acceptance levels for the imperfections identified during testing must be defined by an applicable application standard or specified by the contract. In the vast majority of European and international welding projects, ( Quality levels for imperfections in fusion-welded joints ) is used in tandem with ISO 17637. ISO 5817 categorizes weld quality into three levels: Level B (Stringent), Level C (Intermediate), and Level D (Moderate).
