To measure Weld Throat Thickness, place the 45º angle ends of the Adjustable Fillet Weld Gage flush to the horizontal and vertical members. Loosen the thumb screw and slide the pointer until it touches the face of the weld. Tighten the thumb screw adn read measurement from the 1/16" marks along the pointer.

 

The Adjustable Fillet Weld Gauge also features a sliding measurement scale on the gauge base which, when  placed flush to the horizontal toe of the weld, the offset arm is adjusted to the top of the weld to permit mesurement of unequal weld leg lengths.

* To measure fillet welds, place irregular curve edge flush to horizontal toe of weld so the straight edge is in line with the horizontal member.

* Adjust the offset arm up or down along the diagonal slots until the tip of the arm touches the top of the weld.

* Read the weld size indicated. The increments are in 1/32" and 1/8" markings up to 1". All numerals are etched into the
surface and filled for easier reading

* To measure weld throat thickness, place the 45° angle flush to the horizontal and vertical members. Loosen the thumb screw and slide the pointer until it touches the face of the weld.

* Tighten the thumb screw and read the measurement from the 1/16" calibrations along the pointer. A quick, sure way to find convex or concave welds and to correct them with additional filler material to meet standards.

*  Measure unequal weld leg lengths by sliding the base measurement scale so it is flush to the horizontal toe of the weld. Adjust offset arm to touch top of weld. Add or subtract to obtain length of each leg.
