Hold the contour gage perpendicular to the weld and press it across the weld. When it is assured that the sage is in proper contact with entire surface across the weld and the base material of the plates on either side, remove the contour gage and prepara a work sheet as shown in the sketch (as shown in page 3) and measure the reinforcement height on the sketch at the highest point.
