• We investigate residual stresses and their relaxation in welded steel plates. Residual stress relaxations rely on redistribution plastic deformations . The its affect the ratio fatigue loads. does not vary range. This paper presents experimental numerical investigations to determine surface through-thickness welding butt-welded plates under actions. X-ray diffraction measurement validates acc...

This paper was aimed to report the 3D finite element analysis simulation of laser welding process of Ti6Al4V 1.7 mm sheets in butt joint in order to predict the temperature distribution, hardness, and weld geometry. The butt-joint welds were made using CO2 laser with the maximum power of 2.2 kW in the continuous wave mode. A part of the experimental work was carried out to verify the weld geome...

Argon arc welding is a frequently used process, to assist various manufacturing processes. The paper highlights the postweld experimental results of similar (EN 10025 Steel-Grade S295) and dissimilar (D36 shipbuilding steel) materials, which possess wide range applications in industries. In this work, studies are carried out for optimality gas tungsten (GTAW) parameters on butt joint with singl...

in the present research, friction stir welding (fsw) process was used for butt joining of pure copper plate to 316l stainless steel plate. mechanical properties and microstructural characteristics of the joint were evaluated by microhardness and tensile tests as well as optical and scanning electron microscope (sem). it was found that microstructure of the weld nugget (wn) has fine grains where...

Butt joints are frequently used in assembly processes. However, relatively little attention has been paid to the proper design and selection of butt joint geometries and processes. In this paper, the assembly accuracy performance of different butt joint geometries and joining processes has been studied by using analytical models for part misalignment in the presence of part dimensional errors, ...
