Finite element analysis of deformation in early stage of multi-pass circumferential dissimilar welding of thick-walled pipes with narrow gap
Three-dimensional thermal elastic-plastic finite element analyses were conducted in order to reveal the mechanism of gap shrinkage in early stage of multi-pass narrow gap welding of thick-walled dissimilar pip...

Iterative substructure method employing concept of inherent strain for large-scale welding problems
When structures such as ships, automobiles, and bridges are assembled by welding, distortion and residual stress are produced as unavoidable consequence of local shrinkage due to welding. The dimensional error...

Martensite transformation of a Cr-Ni type weld metal and its application to analysis of welded joints
We have investigated the martensite transformation phenomena of a Cr-Ni type weld metal, especially the effects of stress and plastic strain that exist before the martensite transformation start. Tensile speci...

A practical method for prediction of distortion produced on large thin plate structures during welding assembly
Fusion welding processes are widely used to assemble large thin plate structures such as ships, automobiles, and passenger trains because of their high productivity. However, welding-induced distortion often i...

Numerical analysis of deformation in multi-pass circumferential TIG welding with narrow gap
As one of the practical issues for narrow gap tungsten inert gas welding, the mechanism of gap width shrinkage in multi-pass circumferential butt welding of thick-walled pipes was examined experimentally and n...
