With a pivoting blade for easy measuring of eleven most specified fillet dimensions. Measures concave or convex seams. Stainless steel blades, etched increments. 1/8 in. thru 1 in. and metric equivalents. Fits in 4-1/2 in. x 2 in. case  Each leaf has two ends. one is for Inch. the other ends for Metric.   The gages possess two ends with one piece. One end is for convex fillet, and the other end is for concave fillet. Rok gauge used high quality stainless steel, the users can used them many times with less worn out.  The gauges comes as a set of individual gauges that used to size fillet welds. In fact, the gauge do not measure fillet welds. Only to determine wheterh the weld is smaller than, larger than, or the exact size of the gauge being used. The set of leaves of the fillet weld gauges like thread gauge go or no go.

 

 Note: The gauge only tells you whether the fillet size "go" or "No go", smaller or larger than the standard.  The inspector checks the size of the actual weld by using one or more gauges to compare the size of the weld to the size of the individual gauges.
The gauges typically come in 1⁄16-in. increments for weld sizes ½ in. and smaller, and in 1⁄8-in. increments for sizes of 5⁄8 in. and larger.

 

* With deburred edges

* Knurled nut hols set 7 pcs together

* How to use fillet welding gauge:

* Welding Gage blade must be flush to the base material with teh tip touching the vertical member. Use the single arc corner for measuring convex welds. use the double arc corners for determining if the welds are concave, if they are, more filler material is required to build weld throat to the size where the tip  

  between the double arcs touch.

* Convex weld

* Place single arc edge flush to base material so blade tip touches vertical member if tip touches the vertical member, the weld size is indicated.

 

    Place double arc edge flush to the base material so tip touches vertical member. if the tip bwtween the double arc touches the centre of the weld, the weld is the profile desired and is the size indicated.
