Prediction of welding stresses in WIC test and its application in pipelines

Abstract: In the present study, the Welding Institute of Canada (WIC) restraint test was used to simulate the restraint conditions of full-scale girth welds on energy pipelines to ascertain the influence of welding process parameters on welding stresses. Finite element models are developed, and validated with neutron diffraction measurements, to evaluate the welding stresses for under-matched, matched and over-matched welds. The effects of heat input, wall thickness and variable restraint lengths of WIC sample are syste… Show more

“…The measurements were performed on a strain scanning diffractometer (KOWARI, ACNS, ANSTO, Lucas Heights, Australia) [9]. A monochromatic beam with λ = 1.67 Å from Si{400} monochromator reflection was used in this analysis.…”

“…Residual strain/stress measurements were conducted in three principal directions including longitudinal (parallel to the welding direction), normal (through thickness of the plate) and transverse (perpendicular to the weld) orientations. Further details of instrumentation and fundamentals of neutron diffraction can be found elsewhere [ 42 , 43 , 44 , 45 ]…”

“…A 3D transient thermal analysis was conducted using a moving Gaussian heat source to compare the thermal response of the parent plate in the WIC and MWIC tests. The analysis methodology was similar to those employed by Darmadi et al [36], Iacobescu [37], Teixeria et al [38] and Alipooramirabad et al [39]. The heat input was calculated in 0.1 s intervals for 8 s and distributed with a standard deviation of 1 mm and a mean that moved from one side to the other at a speed of 7 mm s −1 along the weld surface.…”
