In this paper we developed a novel and cost effective automated system for use in the Australian shipbuilding industry. We began by investigating current shipbuilding processes and determining the most feasible area where automation could be further developed. Then we designed an automation concept with the objective of developing a highly flexible system. A prototype of the integrated tool was developed for preliminary testing in a simulated industry assembly process, the results of which were benchmarked against a manually fabricated assembly. The outcomes from the benchmarking showed the feasibility of such a system and allowed us to determine the future …

The feasibility of using Tandem Gas Metal Arc Welding (T-GMAW) to produce full penetration butt welds in 5mm ship panel steel plates has been assessed and compared to the current Submerged Arc Welding (SAW) process. Experiments conducted show that the T-GMAW process is feasible and demonstrated a significant improvement over the SAW process in several areas including higher travel speed, a reduction in filler material, significantly lower post weld distortion, and a smaller Heat Affected Zone (HAZ), while maintaining similar microstructure and mechanical properties in the weld metal and HAZ.
