Evaluation of tandem gas metal arc welding for low distortion butt-welds in naval shipbuilding

Journal Article


Abstract


  • Tandem gas metal arc welding (T-GMAW) had been indentified as a welding process that is potentially capable of increasing productivity and minimizing distortion in the butt-welding of steel panels for the shipbuilding industry. In this study, the T-GMAW process has been used to butt-weld DH36 steel plate in order to determine its suitability as a replacement for submerged arc welding (SAW) or standard gas-metal-arc welding (GMAW) in naval shipbuilding applications. Experiments conducted show that the T-GMAW process is feasible and provides a significant improvement ove the SAW process in several respects, including higher travel speed, reduction in filler material, significantly lower post-weld distortion and residual stress, and a smaller heat affected zone (HAZ) with finer weld metal and HAZ microstructures. Furthermore, similar mechanical properties to those of SAW were obtained in the weld metal and HAZ.
