Residual stress studies (by centre-hole drilling and finite element analysis) and microstructural computations (using temperature measurements) were carried out on multirun butt welded steel plates. The plates, 200 mm thickness, were in SIS 2134 material (0.12%C, 1.42%Mn, 0.044%V, 0.014%Ti, 0.038%Al). Welding was by submerged arc welding using ESAB OK AUTROD 12.10 filler material and ESAB OK FLUX 10.80 flux
