Abstract: A weld gauge for measuring the dimensions of welds between a base member and a workpiece extending outwardly from the base member at an angle, such as an acute angle or an obtuse angle. The gauge includes aplate having an arm pivotally mounted thereon for movement past a scale on the plate, the arm frictionally engaging the plate so that it can be adjustably put into any one of number of fixed positions along the scale for measurement purposes. The plate of the gauge has an upper margin which extends at an acute angle relative to the horizontal so that the gauge can be placed in the limited space formed by the workpiece extending at an acute angle relative to the base member. The scale is on one face of the plate.
