Abstract: An arc welding method of the present disclosure includes a teaching program creation step, a position detection step, and a welding step. In the position detection step subsequent to the teaching program creation step, a position detection program is executed with use of a welding torch having a servomotor. In the welding step subsequent to the position detection step, a welding program is executed with use of the welding torch. A gain of the servomotor that is used for position detection in the position detection step is higher than a gain of the servomotor that is used for welding in the welding step.
