This project sought to meet manufacturing needs in the small batch-mixed production environment of military shipbuilding with a new arc welding approach that will easily accommodate the multiple parameter-torch setups needed for the full range of fillet weld sizes and dependably provide seam tracking at high production rates. This project integrated the excellent seam tracking small fillet performance of spin-arc gas metal arc welding (GMAW) with a high deposition trailing GMAW torch to develop a new variant of tandem GMAW. It is believed that the tandem spin-arc process will offer the best weld quality, seam tracking performance and productivity over the full range of fillet weld sizes (3 to 8 mm) for ship construction.
