...Akira Maekawa; Hisashi Serizawa; Hidekazu Murakawa The fast numerical simulation method for multipass welding process based on ISM was proposed as the ISM code. Weld residual stress analysis was done using the ISM code for a multipass butt-welded pipe joint and the analysis results were...

...Wei Jiang; Kadda Yahiaoui Welded, thick-walled piping intersections are widely used in many engineering applications including the offshore and nuclear power industries. These components are often fabricated by multipass welding, which inevitably introduces undesirable residual stresses...

...Wei Jiang; Kadda Yahiaoui Piping branch junctions and nozzle attachments to main pressure vessels are common engineering components used in the power, oil and gas, and shipbuilding industries amongst others. These components are usually fabricated by multipass welding. The latter process is known...

... during a multipass welding process is presented. A newly developed partitioning technique has been used to mesh the complex intersection areas of the welded junction. Various phenomena associated with welding, such as temperature dependent material properties, heat loss by convection and latent heat have...
