This paper aims at optimization of process parameters for gas tungsten arc welding (GTAW) of sheet samples of Aluminium alloy AA1100 using AC wave with Argon as inert gas. Tensile properties of parent and welded specimens were determined as per ASTM-E8M standard. Taguchi approach was applied to determine most influential control parameters which will yield better tensile strength of the joints ...

Abstract—Friction stir welding is a modern and an environmentally friendly solid state joining process used to joint relatively lighter family of materials. Recently, friction stir spot welding has been used instead of resistance spot welding which has received considerable attention from the automotive industry. It is environmentally friendly process that eliminated heat and pollution. In this...

in this paper, welding feasibility between aa1100, aa5050 and aa6082 aluminum alloys and a441 aisi steel by friction stir welding has been studied. mathematical analysis of the heat generation during process showed that the maximum temperature produced in aa6082 aluminum alloy and a441 aisi joint but heat distribution in aa1100 aluminum alloy was higher than the other alloys. the investigation ...

Friction stir spot welding (FSSW) is a type of solid state that has been widely developed using both similar and dissimilar materials. Aluminum AA1100 (99% Al) brass (Cu-Zn) with thickness 0.42 mm are used in this joint.

This paper reports on an experimental and finite element analysis (FEA) of the cold extrusion of high-grade (AA1100) aluminium. The influence of die angle, reduction ratio and die land on the extrusion force during the extrusion process was investigated. A forward extrusion die was designed and manufactured for the purpose of the experimental research. Interchangeable elements of the extrusion ...

Abstract Aluminum alloy AA1100 has less wear resistance and mechanical properties than that of other aluminum alloys. This research work is on the fabrication surface composites by friction stir processing (FSP). The are fabricated reinforcing hBN (hexagonal Boron Nitride) in to improve tribological properties. influence process parameters, rotational speed (rpm), transverse (mm/min) microstruc...

The effects of ultrasonic impact peening (UIP) on the mechanical properties and fatigue strength AA1100 alloy were compared to those untreated alloy. UIP technic is widely used in a variety applications increase hardness, tensile strength, surface characteristics, life metals. Due plastic deformation layer, process generated compressive residual stresses metal's upper layers. Extensive investig...

the aim of this article is study of tool plunge depth (tpd) effects on mechanical properties of friction stir welding of aa1100 aluminium alloy to a441 aisi steel. for this purpose the 0.1, 0.2, 0.4, and 0.6 mm tpd selected and other welding parameters kept constant. the results shows that the frictional heat increases and stir zone grain size decreases with increasing tpd at both base metals. ...
