The measurement and prediction of weld residual stresses are complex processes subject to both systematic and random errors. Over the last 20 years the NeT network has undertaken a series of round robin projects examining residual stresses in benchmark weldments of increasing complexity, organised as a series of Task Groups. A NeT Task group comprises manufacture and characterisation of tightly specified and controlled weldments, followed by parallel and independent simulation and measurement round robins. This talk introduces NeT, describes the work of five of its Task Groups, and examines the lessons learned about the reliability and repeatability of both measurements and simulations.
