Friction stir welding does not involve bulk melting of the components that are joined. This has inspired attempts to exploit it for joining materials which differ in properties, chemical composition or structure, and where fusion can lead to detrimental reactions. The purpose of this special issue of Science and Technology of Welding and Joining was to assess the status of friction stir welding...

the spot welding is widely used for joining thin sheets in different industries; such as automotive industry. this method of welding is very easy to automate and maintain. in this study, the effect of nugget diameter on the tensile-shear strength of the spot welding joints was investigated. the specimens were manufactured from aisi 1008 hr sheets with 1.0 mm thickness. the eight different elect...

Friction stir spot welding (FSSW) of dissimilar S45C steel and 6061-T6 aluminum alloy in a butt configuration is experimentally investigated. Butt performed using convex scrolled shoulder tool at different rotational speeds. FSSW joints are successfully fabricated by offsetting the to side. The microstructures three speeds characterized scanning electron microscopy energy dispersive spectrometr...

Friction stir spot welding of dissimilar aluminum and copper sheets was investigated in details using Taguchi approach this study. Analysis variance conducted to identify the effective parameters their contributions on mechanical performance. The findings revealed that outputs followed normal distribution. results indicated rotational speed with contribution 87.7% most parameter maximum tensile...

the microstructure of hp stainless steel in aged and aged + solution annealed conditions and solutionized alloy 800 was characterized by optical microscopy, scanning electron microscopy (sem), and transmission electron microscopy (tem) equipped by eds. all phases present in the above condition were described. the effects of solution annealing heat treatment temperature on the microstructure, te...

Tungsten Inert Gas welding (TIG) process is an important component in many industrial operations. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. This paper presents the influence of welding parameters like welding current, welding speed on strength of low carbon steel on AA1050 material during welding. A plan of experiments bas...
