OVERVIEW
The Skew-T Fillet Weld Gauge and Calculator can be used to check the inspection dimension of an acute and obtuse dihedral angle weldment as well as the angle of the vertical member.
Normally, we think of members being welded together at a 90 degree angle to each other. A special condition exists when members come together and are welded at angles other than 90 degrees and fillet welds are used to make the connection. These conditions are called Skew-T Joints. The angles involved usually are at a 30 degree angle minimum on the acute side. In accordance with AWS standards welds deposited in acute angles less the 30° are not considered as effective in transmitting applied forces
Skew-T welds are usually specified in one of three ways. Theoretical Throat size, Leg Size, or the Inspection Dimension is given.
