Abstract
Point group data obtained by measuring the penetration depth of a keyholeduring laser welding is divided into a plurality of regions in the depth direction of measured values, and evaluation data showing a change in number of points with time is acquired for each of the plurality of regions. An average variation in number of points is calculated for each of the plurality of regions based on the plurality of pieces of evaluation data. When the average variation is equal to or larger than a predetermined threshold, it is determined that measurement of the penetration depth of the keyholeis unstable under the welding condition.
