The present invention provides a welding system and methodology to facilitate an improved fillet weld. The system includes an arc welding subsystem providing a fillet weld that joins one or more members. The arc welding subsystem controls one or more welding parameters and utilizes one or more controlled process variables, to facilitate geometric control of a toe angle, a toe radius, a throat dimension and a penetration depth associated with the joining of the fillet weld and the one or more members. The present invention also includes optimized welding parameters, welding wire alloys, and welding gas mixtures to promote an improved fillet weld.

The welding system of claim 5 wherein the balance circuit is further configured to provide a contactor control signal to the second power supply in response to the first power supply switching on. 10. The welding system of claim 5 wherein the first power supply has a first maximum rated welding current capacity and the second power supply has a second maximum rated welding current capacity difference from the first maximum rated welding current capacity. 11. The welding system of claim 5 wherein both the first power supply and the second power supply are in thermal balance with each other during normal operation. 12. A welding system for delivering a welding current to a load comprising: a first power supply having a welding output connected across the load and operating in a constant voltage mode wherein the first power supply delivers a portion of the welding current to the load; a second power supply having a welding output connected across the load in parallel with the welding output of the first power supply and operating in a constant current mode wherein the second power supply delivers a portion of the welding current to the load; and a control configured to: detect a signal indicative of actual welding output of the first power supply; and output a command signal to the second power supply configured to regulate the welding output of the second power supply such that each power supply supplies an equal portion of the welding current to the load. 13. The welding system of claim 12 wherein the command signal is configured to regulate the output of the second power supply such that each power supply provides an approximate equal amount of welding current to the load relative to each power supply's maximum rated welding current capacity. 14. The welding system of claim 12 wherein the control is further configured to provide a contactor control signal to the second power supply in response to the flow of welding current from the first power supply. 15. The welding system of claim 12 wherein the control is further configured to provide a contactor control signal to the second power supply in response to the first power supply switching on. 16. The welding system of claim 12 wherein the first power supply has a first maximum rated welding current capacity and the second power supply has a second maximum rated welding current capacity different from the first maximum rated welding current capacity. 17. The welding system of claim 12 wherein both the first power supply and the second power supply are in thermal balance with each other during normal operation.
