Control of the Gas Metal Arc welding process is becoming increasingly sophisticated, due to improvements in technology and a better understanding of the process itself. To effectively conduct research in this area, it is necessary to have equipment that is extremely flexible in both architecture and operation. Experimental power sources and a welding test facility have been developed at the University of Wollongong which meet these criteria. The core time-critical control functions are performed by an independent digital signal processor (DSP). Non time-critical functions such as data storage and operator interface are performed by a desktop personal computer. Both computing …

Welding process research is severely hampered when adequate experimental equipment is not available. With the development of numerous welding processes and the control techniques associated with them, the need now exists for experimental equipment that offers the flexibility to control these processes and to set up parameters associated with the research. At the University of Wollongong an experimental research rig has been developed based on a digital signal processor control system that offers the researcher the facilities to study the various processes associated with GMA welding.
