Abstract: In order to provide a method for analysing quality deficiencies of workpieces, preferably vehicle bodies and/or vehicle attachment parts, in particular after and/or whilst passing through a production process in industrial-method plants, preferably after and/or whilst passing through a painting process in painting plants, by means of which method quality deficiencies can be avoided and/or by means of which method quality deficiency causes in the production process can be determined, avoided and/or remedied, it is proposed in accordance with the invention that the method comprises the following steps: creating a workpiece-specific data set, uniquely assigned to a workpiece, at the start of a production process, in particular at the start of a painting process and/or creating a workpiece-carrier-specific data set, uniquely assigned to a workpiece carrier, at the start of a production process, in particular at the start of a painting process; supplementing the workpiece-specific data set while a workpiece is

Abstract: In order to provide an electrocoating plant for coating workpieces, in particular vehicle bodies, comprising at least one immersion bath, in which at least one electrode is disposed, a conveying device, which brings the workpieces into the immersion bath and out of the immersion bath again, and a power supply device, which generates from an a.c. input voltage an output voltage, in particular a d.c.
