Abstract:
1. A welding device to determine welding conditions comprising: an object-to-be-welded information input unit to receive object-to-be-welded information, which is information about an object to be welded; a welding method information input unit to receive welding method information, which is information about an arc welding method; a calculation unit to calculate a quantity of arc heat as a necessary quantity of arc heat based on the object-to-be-welded information and the welding method information, and to calculate 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 based on the necessary quantity of arc heat, the object-to-be-welded information and the welding method information; a display unit to display calculation results of the calculation unit; and a leg length setting unit to change the leg length from the recommended leg length to a determined leg length; wherein, when the leg length is changed from the recommended leg length to the determined leg length, the calculation unit recalculates the wire feed speed from the recommended wire feed speed to a determined wire feed speed, the welding current from the recommended welding current to a determined welding current and the welding voltage from the recommended welding voltage to a determined welding voltage, which are based on the determined leg length, and the display unit displays the recalculation results of the calculation unit.
