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. ...

Part with sculptured surfaces is obtained in three stages: roughing, semi-finishing and finishing. The roughing operation consists in using flat end tools or fillet end tools on sequential horizontal cutting planes to remove the most material from the raw part as rapidly as possible using “Parallel Planes” or “Offset Contours” machining strategy. When roughing deep parts, radial cutting forces,...

The Swedish nuclear waste will be stored in copper canisters and kept isolated deep under ground for at least 100,000 years. To ensure reliable sealing of the canisters, friction stir welding is utilized. To repetitively produce high quality welds, it is vital to use automatic control of the process. A decentralized solution is designed based on an already existing temperature controller and a ...

Four tool plunging paths including a one-time path and three step-by-step were designed to study the effects of on welded joint properties pinless friction stir spot welding (PFSSW). The appearance, cross-sectional microstructure, temperature, microhardness, tensile shear failure load PFSSW thin copper sheets under different explored. Furthermore, fracture modes joints analyzed. Studies showed ...

Dissimilar joint with good quality and mechanical properties is one of the major problems the industries. One of the most commonly used methods to solve this problem is friction stir welding process. In this paper two different tool pin with simple cylindrical and screwed profile were used to finding optimization of friction stir welding parameters to reach best mixing flow, composite structure...

Friction stir lap welding (FSLW) between SPC270 steel sheet and A6061 aluminum alloy were investigated with the effect of tilt angle plunge depth tool. Tilt 3 degree improved material flow suppressed generation defect in weld. The weld strength increased tool achieved maximum value 212 MPa at 0.15 mm depth. From TEM observation, uniform reaction layer 450 nm was formed on interface. On interfac...

In this investigation, the effect of friction stir processing (FSP) parameters such as rotational speed, traverse speed and plunge depth on the tensile strength of AA6063 aluminum alloy was studied. The experiments were carried out as per response surface methodology parametric design concepts to study the influence of various combinations of process parameters. Statistical optimization techniq...
