Abstract
A method for measuring the degree of fusion involves: a step for creating a dividing pulse amplitude curve by using a probe that emits ultrasound beams; a step for scanning the probe that emits ultrasound beams at a predetermined angle on a surface that has weld beads of multiple welding specimens having different degrees of fusion and for obtaining beam path length information from the dividing pulse amplitude curve and the height of an F echo that returned to the probe after hitting the fused section of a welding site; and a step for obtaining a regression formula expressing the relationship between the beam path length information and the degree of fusion.
