Abstract: A test method is provided to reproducibly test under matched HY100 welds to robustly establish the production parameters for the welding process. The test method comprises forming a ‘U’ shaped groove in a plate to which steel members are welded on the reverse side. The steel members comprise transverse members that extend across the weld. The transverse members are arranged at a density of at least four members for each 0.5 m length of weld and preferably five transverse members. The steel members further comprise longitudinal stiffeners that extend parallel to the weld. The longitudinal stiffeners are arranged at a density of two stiffeners per 0.4 m width of the plate. The high density of stiffeners has provided a reproducible and reliable weld test method that is capable of being used to establish and approve production parameters for the welding process of under matched HY100 welds.
