<P>PROBLEM TO BE SOLVED: To rapidly perform acceptance or rejection decisions by reading the intersection between the scale of the indication section of a slider and a scale corresponding to magnifications. Ž<P>SOLUTION: A welding gauge for measurement of pressure welding is provided with: a rotor (b) rotatably pivoted to a gauge body (a) by a pin 12; a gap/throat gauge body (c); an abutting part 4 that opposes a first jaw plate section 3 projecting from a lower portion; and a slider (d) for forming a window hole 5 in the inside slidably in a lower portion of the gauge body (a), allows an indication section 7 having a round rod diameter measurement scale 8, such as a reinforcing bar diameter, having a high utilization frequency to project onto the surface from a prescribed number of places in an upper end section 6, adds a measurement scale 9 corresponding to magnifications prescribed in an inspection having functions for measuring the diameter of a bulge in a pressure welding section corresponding to the reinforcing bar diameter, or the like at the indication section 7, for measuring bulge length at the pressure welding section, and for measuring deviation of a pressure welding surface to a back section 2 of the gauge body (a), and adds a measurement scale 5a that can be seen from the window hole 5. In measurement by the first jaw section 3 and the abutting part 4 of the slider (d), the intersection between the measurement scale 8 and the measurement scale 9 corresponding to magnifications added to the indication section 7 of the slid slider (d) is read for determining acceptance or rejection.
