Abstract

See full text

The purpose is to determine occurrence of expulsion in seam welding with high accuracy. A welding determination device includes: a measurement unit configured to measure temperature of a joint portion between strip-shaped sheets (for example, steel strips) to be joined by seam welding; and a determination unit configured to, based on a measurement result by the measurement unit, calculate an average temperature Tave and a temperature difference ΔT of the joint portion and, when the average temperature Tave is more than or equal to a first threshold value that is set according to the sheet thickness of each of the strip-shaped sheets and the temperature difference ΔT is more than or equal to a second threshold value, determine that expulsion has occurred at the joint portion.
