How to use: CHECKING FILLET LEG LENGTH: -Slide the weld gauge horizontally so that the tip of the arc is perpendicular to the other side, if tip touches the vertical member, the weld size is indicated. CHECKING FILLET THROATS THICKNESS: -Slide the weld gauge horizontally so that the tip of the arc is perpendicular to the other side, if the protusion in the middle of the weld gauge touches the centre of the weld, the weld is the profle desired and conforms to the size indicated by the weld gauge.
