Welding Distortion of a Thin-Plate Panel Structure
Welding thin-plate panel structures often results in warping of the panels. Several mitigation methods, including preheating and prestressing the plates during assembly, have been investigated and used by some fabricators. This paper studies the distortion mechanisms and the effect of welding sequence on panel distortion. In this study, distortion behaviors, including local plate bending and bu...
متن کاملDistortion of laser welded titanium plates.
The distortion of laser welded titanium plates was assessed for different operating conditions of the laser welding device, and with different welding parameters (in terms of weld point and prewelding). In this study, Nd : YAG laser welding device was used to join the titanium plates. The results showed that distortion increased stepwise after each welding point along the welding zone (one-side...
متن کاملEffect of Process Parameters on Angular Distortion of Gas Tungsten Arc Welded SS 302 and MS Plate
Tungsten Inert Gas (TIG) welding is a widely applied manufacturing process. Angular distortion is a major problem and most pronounced among different types of distortion in the butt welded plates. This angular distortion is mainly due to nonuniform transverse shrinkage along the depth of the plates welded. Restriction of this distortion by restraint may lead to higher residual stresses. However...
متن کاملSimulation-based numerical optimization of arc welding process for reduced distortion in welded structures
This paper presents an effective numerical approach for welding process parameter optimization to minimize weld-induced distortion in structures. A numerical optimization framework based on coupled Genetic Algorithm (GA) and Finite Element Analysis (FEA) is developed and implemented for a low and a high fidelity model. Classical weakly coupled thermo-mechanical analysis with thermo-elasto-plast...
متن کاملFracture Assessments of Welded Structures
Weldments are particularly susceptible to fracture due to defects, material property variations, and residual stresses created during the welding process. It is common in fracture assessments of welded structures to ignore these features; defects are often idealized to be crack-like, weld properties to be homogeneous, and residual stresses to be uniaxial and tensile or nonexistent. This paper p...
