Welding condition determining method

摘要

A method to determine welding conditions includes relational expressions or tables about various parameters for setting welding conditions. The method can determine and display the recommended values for the welding conditions which are suitable for the information about the object to be welded and the information about the welding method set by the operator. The welding conditions include a welding current, a welding voltage, a wire feed speed, a welding speed, and a leg length. Furthermore, if the operator changes the recommended value for a welding condition to a new value, the method can determine new recommended values for the other welding conditions compatible with the new value and display the new recommended values.

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.
