Influence of welding sequence on welding deformation and residual stress of a stiffened plate structure

Ocean Engineering, 2015
An important consideration in the safe and efficient manufacture and operation of marine structures is the possible distortion, and consequential induced residual stress, owing to welding. This paper deals with welding simulation of a stiffened plate structure with longitudinal and transverse stiffeners using a thermal elasto-plastic FE method.

Influences of Welding Sequence on Residual Stress of Plate Butt Welding

Applied Mechanics and Materials, 2010
For the plate butt welding of the same materials with different geometry structures, the numerical simulation was adopted to analyze the influences of welding sequence on transverse and longitudinal residual stress in the process of multi-layer and multi-pass welding.

Influence of the welding sequence on residual stress and distortion of fillet welded structures

Marine Structures, 2016
Abstract T-joints are one of the most common welded joints used in the construction of offshore structures, including ships and platforms. In the present study, a sequentially coupled thermo-mechanical finite element model that considers temperature-dependent material properties, high temperature effects and a moving volumetric heat source was used ...

Effect of welding sequence and direction on angular distortions in butt-welded plates

The Journal of Strain Analysis for Engineering Design, 2011
During arc welding process, non-uniform heating and cooling lead to non-uniform expansion and contraction of the weld and surrounding base metal which result in undesirable residual stresses and distortions in the welded joint. Among different types of welding distortions, angular distortions produced by butt welding of plates are of major concern in ...
