Zusammenfassung:	The invention relates to a method for automatically determining optimum welding parameters (Pi,optfor carrying out a weld on a workpiece (4), wherein a plurality of test welds is carried out on test workpieces (9) along test welding tracks (10), and at each test weld at least one welding parameter (Pi(x)) is changed automatically along the test welding track (10) from a predefined initial value (PI,A) to a predefined final value (Pi,E), each resulting test weld seam (11) is measured along the test welding track (10) with at least one sensor (12), and at least one sensor signal (Sj(Pi(x)) is received, at least one quality parameter (Qk (Sj (Pi(x))) which characterizes each test weld seam (11) is calculated from at least one sensor signal (Sj(Pi(x))), a quality function (G(Qk (Sj (Pi(x)))for characterizing the quality of the test weld seams (11) in accordance with the changed weld parameters (Pi(x)) is calculated from the at least one quality parameter (Qk (Sj (Pi(x))), an optimum of the quality function (Gopt
