Strain mapping in a repaired weld on a steam header (Bouchard et al., 2005). (a) Schematic diagram of the original pipe, produced by manual arc butt welding of two ex-steam-headers. (b) Axial and (c) hoop views of the repair introduced in the weld. A section of the original weld was removed, and subsequently filled with new material. (d) Axial strain mapped on plane BB′CC′ in the heat-affected zone of the repair. The symbols indicate the locations and values of the actual measurements. The profile of the cross section was produced using a coordinate-measuring machine. |
