Abstract:
1. A method performed by a control apparatus to determine welding conditions, comprising: a first step of receiving object-to-be-welded information, which is information about an object to be welded; a second step of receiving welding method information, which is information about an arc welding method; a third step of calculating a necessary quantity of arc heat, which is based on the object-to-be-welded information and the welding method information; a fourth step of calculating a wire feed speed as a recommended wire feed speed, a leg length as a recommended leg length, a welding speed as a recommended welding speed, a welding current as a recommended welding current, and a welding voltage as a recommended welding voltage, which are based on the object-to-be-welded information, the welding method information, and the necessary quantity of arc heat; a fifth step of changing the leg length from the recommended leg length th to a determined leg length; and a sixth step of determining the wire feed speed as a determined wire feed speed, the welding current as a determined welding current and the welding voltage as a determined welding voltage, which are based on the determined leg length, wherein the recommended welding speed is maintained and determined as a determined welding speed.
