The New Nuclear Manufacturing (NNUMAN) Programme is a five year UK research project developing manufacturing technologies for next generation nuclear power plants. One of its research themes is advanced joining. Within this theme NNUMAN has manufactured, characterised, and modelled benchmark narrow groove weldments in SA508 Gr 3 Cl 1 low alloy steel over a range of thicknesses up to 130 mm thick using four welding processes: submerged arc (SAW), gas-tungsten arc (GTAW), Electron beam (EB) and cold wire laser (CWL). This paper describes the manufacture and characterisation of the weldments, including diverse residual stress measurements both before and after post weld heat treatment (PWHT).
