Advanced materials generally require novel joining techniques. Developments in new research should be conducted hand with work on weldability and capacity aspects. Sound joint quality for any material has always been considered a milestone development scheme material, particularly terms of widespread applications. Better understanding the microstructure-mechanical properties relationships bonded or welded joints will feed back to activities both conventional areas. The two processes...
Electron beam (EB) welding was performed on three different aluminium alloys, namely alloys 2024, 5005, and 6061 (plate thickness 5 mm except alloy 5005 which 3 in thickness), to establish the local microstructure–property relationships that would satisfy service requirements for an electron welded component with weld zone strength undermatching. Microstructural characterisation of metals carried out by optical scanning microscopy. A very low level porosity observed all EB welds owing...
This paper investigates the potential of mechanical tensioning (MT) to reduce magnitude residual stresses in welds and eliminate buckling distortion. Both friction stir (FSW) arc have been produced from aluminium alloy AA2024, with different levels tensile stress applied along weld line either during or after welding. The resulting characterised terms out plane distortion, microstructure. Buckling distortion was eliminated by stretching plates between 35 70% yield material For each set...
Abstract In this study, a low-alloy steel component was manufactured using specially produced E70C-6M class of metal-cored welding wire according to AWS A5.18 standard for the WAAM process. The first subjected radiographic examination detect any weld defect. Uniaxial tensile tests were conducted bottom, middle and upper regions. micro-hardness performed parallel deposition direction. results show that microstructures varied from base metal face region component, including top sections....
Laser beam welding is currently used in the of steels, aluminium alloys, thin sheets, and dissimilar materials. This high power density process has unique advantages cost effectiveness, deep penetration, narrow bead heat affected zone (HAZ) widths, low distortion compared to other conventional processes. However, metallurgical mechanical properties laser welds response materials this new are not yet fully established. The may lead drastic changes microstructure with accompanying effects on...
A study was carried out on laser and resistance spot welds in overlapped sheets of dual phase advanced high strength steel (DP780) deep drawing (DC04) 2˙0 mm thickness. The aim the to investigate fatigue performance these joints under tensile shear loading as well monotonic for applications automotive industry. mechanical properties, failure behaviour life analyses similar dissimilar were investigated by experimental numerical methods. structural stress concept used describe lives welded...
