Suitable testing arrangements are made for assessing the strength of welded T-joint specimens and providing input for the validation of finite element simulations of their behaviour under load. Material characterisation across the various weld areas is carried out through tensile and hardness tests as well as standard metallographic procedures for examining the microstructure. Strain is measured at critical locations identified through initial FEM analysis. Failure mechanisms are monitored, failure loads recorded and linked to the joint material and geometric characteristics. The consistency of FEM predictions with these measurements and observations provide a reasonable degree of confidence that the developed model cna yield reliable stress and strain distributions for failure analysis.
