B.2 STT OVERVIEW
Figure B-1 illustrates the variables of the STT welding process. Each of these variables can be
programmed into a weld table using the
Wave Designer software. Figure B-2 shows how the
STT waveform and the primary variables produce a weld.
For more details on each of these variables, refer to Primary STT Waveform Components and
Secondary STT Waveform Components in paragraphs B.5 and B.6 of this appendix.
