Turn the gauge90 , being careful to apply a constant back pressureto the Hold the gauge as square as possible with thefitting to obtain an accurate reading. Lock theretaining screw. Reverse the 90 turn and remove thegauge. You're now ready to read the incrementopposite the red When the red line aligns with the 1/32 incrementline you have a good internal alignment and can be determined from the zero lineby increment markings of 1/16 Spacing GaugeEasy operation determines rootweld Unlock the retaining screw and insertthe gauge interior alignment stopsbetween the two pieces of pipe to Insert the leg with the longer taper intothe root gap until it makes contact withboth sides of the Re-lock the retaining screw, removethe gauge and read The scale is calibrated in fractionaldimensions from 1/32 to 3/16 in 1/16 inchincrements.

Not any more. Now you canmeasure fillet welds from 1/8" to 1" (with 1/32" accuracy)with one economical, simple to understand Adjustable Fillet Weld Gauge uses anoffset arm which slides at a 45 angle to make fillet weldlength measurements. Simply adjust the arm until it touchesthe toe of the vertical leg. The gauge is calibrated to 32nds,with metric equivalents given, so you get more accuratereadings.

4 Four screws hold the offset arm in position forfuture gauge also measures weld throat thickness to 1/16" by adjusting a pointer until it touches the centre of theweld. A thumb screw holds the pointer in position for futurereference. If the weld is concave, more filler material can beadded to build the weld throat up to Adjustable Weld Gauge measures both leglengths and weld throat fillet weld Adjustable Fillet Weld Gauge is made ofdurable, rust resistant stainless steel. Its 2 x 3" slim designweighs only 1 oz., fits easily into a shirt pocket. Andbecause there is just one gauge needed to make allmeasurements, the chance of losing essential fillet weldgauge blades is eliminated.

Measure unequal weld leglengths by sliding the base measure-ment scale so it is flush to the horizontaltoe of the weld. Adjust offset arm totouch top of weld. Add or subtract toobtain length of each the thumb screw and read themeasurement from the 1/16" calibra-tions along the pointer. A quick, sureway to find convex or concave weldsand to correct them with additional fillermaterial to meet measure weld throat thickness,place the 45 angle flush to thehorizontal and vertical the thumb screw and slide thepointer until it touches the face of the weld size indicated.
