A weld detecting method that detects a weld on a work includes: obtaining in advance at least one correlation, from among a correlation between a width of the neck and an amount of elongation of the work and a correlation between the width of the neck and an amount of change in at least one of a sheet thickness and a sheet width of the work before and after elongation of the work, and calculating the width of the neck based on the at least one correlation by obtaining at least one of the sheet thickness, the sheet width, or the amount of elongation of the work from the obtained at least one correlation; setting a conveying speed, according to the calculated width of the neck; and detecting the neck by measuring the sheet width of the work at predetermined intervals, while conveying the work the set conveying speed.
A weld detecting method that detects a weld on a work, by detecting a neck formed at the weld on the work, when elongating the work, comprising:
A weld detecting method that detects a weld on a work having a weld, by detecting a neck formed at the weld on the work, while conveying the work at a predetermined conveying speed, when elongating the work, comprising:
A weld detecting apparatus that detects a weld on a work, by detecting a neck formed at the weld on the work, when elongating the work, comprising:
A weld detecting apparatus that detects a weld on a work, by detecting a neck formed at the weld on the work while conveying the work at a predetermined conveying speed, when elongating the work, comprising:
