LASER WELDING OF NAVY SHIP CONSTRUCTION MATERIALS

An experimental investigation was conducted of laser welding of Navy ship construction materials. Bead-on-plate penetrations were formed in 1/4-in.-thick HY-130 steel, 1/16-in.-thick HY-180 steel, 1/8- and 1/4-in.-thick Ti-6Al-4V titanium alloy and in 1/8-in.-thick 5456 aluminum alloy. Continuous carbon-dioxide laser power levels to 8 kW were used; welding speed was varied from 20 to 180 ipm in order to establish appropriate welding parameters. The bead-on-plate penetrations were initially screened by visual, metallographic, NDT and mechanical tests and then forwarded to NSSC for more detailed evaluation. The finished samples, which were 5 x 7 in. in size, exhibited excellent top and bottom surface bead characteristics and defect-free fusion zones. (Modified author abstract)
