Welding Inspection -
Many characteristics of a weld can be evaluated during welding inspection, some relating to the welds size, and others relating of weld discontinuities, the size of a weld
undersized weld's may not withstand stresses applied during service. Weld discontinuities can also be important. These are imperfections within or adjacent to the weld, which may or may not, dependent on their size and/or location, prevent the weld from meeting its intended performance. Typically these discontinuities, when of unacceptable size , are referred to as welding defects.
