Prediction of Welding Distortion During the Assembly Process of Thin Plate Structures (1st Report)—Prediction of Welding Distortion Considering Gap and Misalignment—
Interface Element Welding Distortion Welding Sequence Gap Misalignment
2009/5/19
The welding distortion of a plate structure during the assembly process is influenced not only by the local shrinkage due to the welding thermal cycle but also by the root gap and the misalignment. Th...
Development of Large-scaled FEM for Analysis of Mechanical Problems in Welding
FEM Mechanical Problems Welding
2009/4/30
Finite element method is a powerful tool for predicting welding distortion. However, the mechanical phenomena in welding are strong non-linear transient problems and thermal-elastic-plastic FE analysi...
Estimation of Welding Distortion Using Neural Network
estimation welding distortion neural network
2009/4/29
The residual deformation induced by welding processes becomes a cause of repair work at the subsequent process. Therefore it is necessary to manage the assembly of welded structures by estimating acc...

Optimization of Torch Movements Welding Cutting Ant Colony Method
2009/4/1
Though many methods are applied to solve the combinatorial optimization problem, there are many cases in which the solution can not be solved in practical computation time, even if the computer become...
Study of Transverse Shrinkage Generated in Steel with Phase Transformation by Welding
transverse shrinkage welding
2009/3/30
This paper deals with the effect of phase transformation on the transverse shrinkage by comparing experimental data and numerical results of transverse shrinkage generated by welding. Both mild steel ...
Optimization of Welding Route by Automatic Machine Using Reinforcement Learning Method
hull block grillage structure
2009/3/27
A hull block is generally composed of skin plates, longitudinals and transverse webs as a grillage structure, and longitudinals and transverse webs are joined by fillet weld on a skin plate panel.

LNG SPB system
2009/3/27
New type of LNG carrier with independent aluminum tanks of prismatic shape, SPB system (Self-supporting Prismatic Tank Type-B System), was developed in Ishikawajima-Harima Heavy Industries, Co., Ltd.(...
Study on Quality Improvement of Filters for Particulate Respirators Used for Welding Work
washable filters shipyards
2009/3/27
The application of washable filters for particulate respirators in shipyards is reported; the problems concerning maintenance and care of the filters are discussed in consideration of filter features.
For the same horse power of the marine desiel, to minimize
the hull weight is the key factor in order to raise the steel
ship speed. At present, thin high and higher tensile steel
plates are widel...
