The copper alloy UNS-C27200 is a binary brass, composed of 38wt%Zn, beeing one the most used in industry. union Cu-Zn alloys by conventional welding fusion thin plates presents several challenges. Friction Stir Welding (FSW) process performs two, or more materials, through rotating tool that travels throughout region. One great advantages FSW working below melting point material, which reduces ...

In the present paper the effects of the thermal and mechanical actions on the residual stress field occurring in friction stir welding (FSW) of AA7075-T6 were investigated. Both numerical and experimental analyses were carried out to highlight the metallurgical phenomena and induced residual stresses in FS welded blanks. The welding process was simulated using a continuous rigid-viscoplastic fi...

Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminium alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be one of the most significant developments in metal joinin...

Friction stir welding (FSW) has promising application potential in Mg alloys. However, the texture distribution in stir zone (SZ) is usually complicated for Mg alloys, which deterioriates the joint performance. In this study, the texture distribution in SZ was tailored by applying two kinds of post-weld compression deformation along normal direction (ND) or welding direction (WD) of the FSWed A...

Using friction heat, welded joints of the Friction stir welding (FSW) process are made that utilized to forge metal components together. Since there is no parent melting, several advantages obtained by FSW over fusion welding. The alloys AA6XXX and AA7XXX Al two sets most extensively structural materials in rail transportation, automotive, aerospace industries. objective present study was inves...

Aluminum is a material that soft, lightweight, resistant to corrosion, and has good electrical thermal conductivity. specific gravity of about 2.65-2.8 kg/dm³, melting point 658ºC, tensile strength 90 MPa. 1100 series an aluminum alloy mixed with other materials, such as copper, iron, chrome, manganese, zinc, content 99,0%. Welding the joining two metals in liquid state or without filler. FSW (...

Friction stir welding is not used for hard alloys because of premature tool failure. A scheme is created which exploits the physical three-dimensional heat and mass flow models, and implements them into a fast calculation algorithm, which when combined with damage accumulation models, enables the plotting of tool durability maps which define the domains of satisfactory tool life. It is shown th...

This paper focuses on optimizing process parameters such as tool rotating speed, preheat-treated workpiece temperature, traverse and pin profile for dissimilar friction stir welding (FSW) of brass AA 6063. The hardness the stir-welded joint created is measured a response variable. Taguchi design experiments approach was utilized to finalize experimental strategy, ANOVA employed analyze data. be...
