Web2. Insert the legs (wires) into the root gap space or the two pieces of pipe to be fitted. Turn the gauge 90°, being careful to apply a constant back pressure to the barrel. 3. Hold the gauge as square as possible with the fitting to obtain an accurate reading. Lock the retaining screw. Reverse the 90° turn and remove the gauge. WebA root opening not exceeding 3/16 in. is generally permitted therein if the weld size is increased by the amount of the root opening or it is demonstrated that the required effective throat has been obtained. For plate thicknesses greater than or equal to 3 in., a 5/16-in. root opening is permitted if suitable backing is used.
WebIt is generally recommended that the root gap be at least 1/32" larger than the diameter of welding filler wire to be used. This will allow for manipulation of the filler wire even when some shrinkage occurs during tack welding and closure welding. 4. Purging of the weld zone is done at about 40 CFH.
