摘要

The mechanical tests(tensile strength, impact toughness) are performed to develop a weld conditions for high strength steel. The effects of heat input, weld geometry(root face, root gap, groove angle), electrode type, plate thickness are experimentally analyzed using Taguchi method with an orthogonal L18(2{sup}1×3{sup}7) array. From the experiments and the ANOVA analysis, effects of the main factors as well as the interactions between any two factors are quantitatively analyzed and the equations for the mechanical properties as functions of the weld conditions are derived.
