TWI Industrial Member Report Summary 340/1987
R H Leggatt
This report presents the results of a programme of surface and internal residual stress measurements in MIG welded aluminium alloy panels of 10 and 50mm thickness. The parent/weld metal combinations used were 5456-H116 with 5556 welding wire, 6061-T651 with 5356 and 4043 wire, 5083-0 with 5183 and 2219-T87 with 2319 wire. The residual stress measurement methods used were centre-hole rosette gauges, sectioning and neutron diffraction. The measured residual stresses will be used in the assessment of wide plate fracture test specimens extracted from nominally identical test panels.
