Abstract
A pulse arc welding profile control method, a control device, a welding system, a welding program, and a welding power supply are provided in which, even when a pulse arc welding method is used, protruding change information is extractable at high accuracy without influence from a welding current or an arc voltage having a pulse shape. An electric change amount detected at the time of weaving includes, as a parameter, at least one among a welding current detection signal and an arc voltage detection signal, takes a predetermined period as one period, calculates an average value of the electric change amount in each one period, and extracts, on the basis of the average value, the protruding change information in a groove to follow a welding line.
