Forging steel components are used to control flow of products in the oil industry. These steels have high hardenability, requiring post weld heat treatment (PWHT) to satisfy strength/hardness in heat affected zones and reduce residual stresses. PWHT is impractical in field, thus Ni alloy weld-buttering layer is deposited on the steel, which is PWHT in shop. During deposit, partially melted zones occur at fusion boundaries causing adverse microstructures and together with hydrogen ingress and residual stresses can lead to cracks. To minimise cracking, an approach is to change welding parameters and bead sequence to optimise interface microstructure. However, effect of changes on stress at interface must be known, as stresses will drive cracks. This experiment will provide data to understand the influence that welding parameters and bead sequence have on weld cracking in these components.
