Abstract:

The report was developed under SBIR contract for Topic N04-124 Joining Methodologies for Titanium Alloys. This investigation has established the hybrid plasmaGMAW Super-MIG weld process as a viable process for welding titanium. Compared to traditional GMAW welding this hybrid process dramatically increases welding speed and penetration both more than double while producing weld joints with minimal spatter and with superior profile and mechanical properties. Weld joints observed had a high degree of visual and metallurgical quality free of porosity, cracks and contamination. The Super-MIG process demonstrated capability for various types of automated welding of Titanium structures.
