The dissimilar joint between aluminum/titanium alloys (Al 6082 and Ti G2) were successfully achieved by CO2 laser welding with a single pass and without filler material using the overlap joint design. Laser welding parameters ranges combinations were experimentally determined using Taguchi approach with the objective of producing welded joint with acceptable welding profile and high quality of ...

BlastAlloy 160 (BA160) is a low-carbon martensitic steel strengthened by copper and M2C precipitates. Heat-affected zone (HAZ) microstructure evaluation of BA160 exhibited softening in samples subjected to the coarse-grained HAZ thermal simulations of this steel. This softening is partially attributed to dissolution of copper precipitates and metal carbides. After subjecting these coarse-graine...

Observation of the weld pool provides an effective path to understand and control the welding process. Observation data also attribute to the validation of numerical models, which helps researchers to analyze and evaluate the welding process. Extensive research has been conducted to provide in situ monitoring of the weld pool. The arc sensor was one of the first few sensors that was adopted for...

This paper develops a vision-based neuro-fuzzy system to control the weld joint penetration in Gas Tungsten Arc Welding (GTAW) of thin sheets. To this end, a camera equipped with a specially designed composite light-filter is used to observe the weld pool from the topside of the workpiece so that comparatively distinct images of the weld pool are obtained. As the Backside weld Width (BW) reflec...

Magnetically impelled arc butt (MIAB) welding is a solid-state technique of that utilizes the heating effect high-speed rotating for formation weld. The process exhibits lower time and power consumption compared to conventional processes tube–tube joining. However, available research reports on MIAB Mild Steel (MS)1018 are still inadequate lack details required extending applications this proce...

Fusion welding is a commonly applied manufacturing process in all fields of industry. Some imperfections (formation coarse-grained microstructure, decrease mechanical property, etc.) can occur especially the fusion welding-based fabrication aluminum alloys which have specific features, such as having high thermal conductivity, expansion coefficient, hydrogen solubility liquid state, and oxide l...

Abstract Microstructure development is examined for a specialized spot weld that used as solid-state closure process austenitic stainless steel tubing, referred to pinch welding. In order elucidate the microstructural evolution of weld, series test welds were made at nominal conditions using tubing and production like components. These normally terminate after twelve cycles 60 Hz AC process. th...

In this study, 2024 aluminum alloy was diffusion bonded to identify the effect of bonding temperature, applied pressure, and heating time on microstructure, hardness, strength. The shear strength increased from 62.5 MPa 81.2 along with rise in temperatures 440 °C 490 °C. rose an optimal value by extending 30 min 240 at a temperature constant pressure 5 MPa. addition, various post-weld heat trea...
