The thermal shrinkage technique with previously proposed input parameter values for single-pass welding was applied to a multi-layer butt-welded joint four layers and six passes validate whether these parameters are applicable welded joints. out-of-plate displacement distributions of the obtained using were in good agreement those elastic-plastic analysis an experiment. angular distortion trans...

This work analyzes the Tungsten Inert Gas (TIG)welded joint of AZ31 magnesium alloy and pitting corrosion stress field at different depths under tensile load via ANSYS finite element method. The strengths strain fields inside pit were substantially higher than average strength level matrix. Therefore, influence applied load, will fail first. Based on study corrosion, a model was developed to ex...

This study represents simulation of single spot and multi spot welded specimen by using Monte carol method i.e. Latin hypercube sampling. A three dimensional nonlinear finite element analysis of multi-spot welded lap shear specimen is performed and uncertainty in shear strength of spot weld is analyzed. Thickness and nugget radius are randomly varied within effective range and their effect on t...

Friction welding of cast Fe-40Al alloy was carried out at 1000 rmp for various friction times, friction pressures, and forging pressures. The microstructures of the interface of welded samples were analyzed by optical and scanning electron microscopy (SEM). Micrographs demonstrated that excellent welding formed continuously along the interface, except for samples welded for 3 s. Chemical compos...

Three-dimensional finite element modeling of residual stresses in a girth-welded pipe is presented in this paper, with an emphasis on modeling procedures for the global residual stress characteristics. The shell element model with a heat source moving along the circumferential joint is demonstrated to be cost effective and capable of predicting the global residual stress features. Transient res...
