Welding is a major manufacturing process that joins two or more pieces of materials together
through heating/mixing them followed by cooling/solidification. The goal of welding …

The paper describes the application of the finite element method to predict the thermal,
material and mechanical effects of welding; Computational Welding Mechanics (CWM). The …

A major concern when carrying out welding and heat treatment simulations is to accurately
model material behaviour as it varies with temperature and composition. Early in the product …

A finite element model was developed to predict weld residual stress and simulate the
vibratory stress relief. Both resonant and nonresonant vibration stress relief were studied to …

Publisher Summary This chapter discusses that residual stress is defined as any stress that
would exist in a continuum body if all external loads were removed. Welding residual …

This paper focuses on the use of simulations for welding and heat treatment. It presents the
validation of welding and heat treatment on a simple geometry. Transient temperature and …

The present study deals with a new technique for controlling the weld-induced distortion.
This developed technique involves in-situ preheating of welding filler wire before it emerges …

Two distortion modeling methods, mapping plastic strain and lump-pass modeling, were
developed and validated for predicting distortion on large welded structures to reduce the …

The objective is to demonstrate a capability developed to explore a design space to
minimize distortion and evaluate the sensitivity of the distortion of an edge weld on a 152× …

Virtual fabrication technology (VFT) weld modeling software has been mainly used in thick-
structure welding simulation. Recently both US and European shipyards have shown strong …
