Study of Residual Stresses and Distortion in Structural Weldments in High-Strength Steels.

Abstract

Numerical analyses based on the finite element method for the prediction of temperatures, thermal strains, and residual stresses due to welding and of the fracture characteristics of weldments are detailed. The obtained results are compared with experimentally obtained data from butt welding 1 in thick HY-130 steel plates using the gas metal arc process. Experimental results on the effects various welding parameters have on the welding distortion of Nickel-Aluminum bronze thin weldments are also included. Optimum welding procedures are then proposed. Finally, initial efforts toward studying the thermal stress relieving operation are outlined. They include a simple mathematical model for the description of the phenomena involved and a series of experiments. (Author)
