Abstract


  • The objective of this study is to determine an optimal welding procedure that can be

    implemented to repair damaged Nickel Aluminium Bronze (NAB) components. NAB is commonly

    used in marine applications where components are subject to a constant corrosive environment and

    high stresses. Research into ideal NAB microstructure for a marine application, was performed in

    order to gain a baseline for experimental analysis of potential welding procedures. The results

    indicated that the welding repair can be performed with a wide range of heat input. The effect of

    post-weld heat treatment (PWHT) on the microstructure and mechanical properties in the heat

    affected zone (HAZ) and weld metal was also investigated in this research. The dominant

    microstructure in weld metal at as-welded condition is coarse Widmanstatten type structure with

    high hardness; post-weld heat treatment resulted in significant grain refinement and hardness

    reduction in weld metal.
