Along with powerful and precise welding current sources, the SPATZQS PC
quality assurance software constitutes another key element of a quality assurance concept for
high-quality resistance-welded joints. This applies in particular when manufacturing products
which are subject to high cost pressure as a result of large production quantities.
Apart from serving as a means of documenting and archiving welding process data for up and running production operations, the SPATZQS PC quality assurance software is also a particularly efficient tool for use in attaining and verifying the necessary machine and process capabilities in connection with commissioning and process optimisation measures.
Installed on the office PC, the SPATZQS PC quality assurance software permits offline analysis of the welding process data records recorded by the SPATZMulti04, AutoSPATZ, DragSPATZ and SPATZ welding systems. The data records of the last 10,000 welds, which are transferred via SPATZBG-02, AutoSPATZAS-01 or AutoSPATZAS-32, contain the complete process parameters for each individual weld. Analysis and evaluation of all the data can be carried out at spread or concentrated intervals, according to either delivery batches or production time. This means that welding process data can be assessed at time intervals ranging from a few seconds to days or weeks, or in quantities ranging from individual welds to thousands of welds.
The scope of assessment intervals enables factors and correlations to be identified which previously went unnoticed. All analyses can be printed out for documentation purposes. Additional comments can also be inserted into the analysis record in a special entry field.
Both logs with time stamps and quality control charts can be generated for all welding process parameters. The quality control charts contain all the key characteristics which are necessary for the purposes of statistical process control (SPC). In addition to analyse the total population of all welding data, it is even possible to carry out welddata or programme-related analysis. Independent analysis is possible for each of the 63 available welding programmes.
