Abstract
In an arc-tracking welding method and a welding device of the present invention, a deviation amount between a weaving center and a welding line is obtained based on a first relationship and a second relationship. The first relationship is a relationship between a weaving position and any one element of three electrical first to third elements related to Ohm's law, the relationship being obtained based on a physical model of an arc welding phenomenon and being associated with the deviation amount. The second relationship is a relationship between the weaving position and the element, the relationship being obtained based on the element in welding power.
