A Proposal of a Heat Input Model, for Heating Correction, on Welded Steel Structural Members

Abstract

A series of experiments and analyses were conducted for evaluating a simple heat input model, for heating correction on welded steel structural members. The heating experiment on steel plates, with different thicknesses, was simulated using thermal elastic– plastic analysis. The temperature histories, deformations and residual stresses of plates could be simulated by the simplified heat source model, proposed in this study. The applicability of the heat source model was verified, by simulating the heating correction for T-shaped fillet welded joints.
