Method for establishing welding parameters for a welding process

A method for establishing welding parameters (P) for a welding process in which a welding torch (2) is guided along a predefined arbitrary welding path (3) over the at least one workpiece (4) to be worked and welding parameters (P) determined depending on the respective position on the welding path (3) are set for the working of the at least one workpiece (4), wherein before establishing the welding parameters (P) of the welding process, ideal welding parameters (Pi) are determined by means of test welding processes on several test workpieces (8) along test welding paths (9) under a specific position and arrangement of the test workpieces (8) in each case in relation to the gravitational acceleration vector (g) and a specific tangential vector (t) of the test welding path (9) and are stored, and the welding parameters (P) at the respective position on the welding path (3) for the welding process to be carried out are established depending on the actual position and arrangement of the at least one workpiece (4) in relation to the gravitational acceleration vector (g) and the actual tangential vector (t) of the welding path (3) by interpolation of the values of the stored ideal welding parameters (Pi) for the specific positions and arrangements of the test workpieces (8) in relation to the gravitational acceleration vector (g) and the specific tangential vectors (t) of the test welding paths (9).
