Studying the Possibility to Weld AA1100 Aluminum Alloy by Friction Stir Spot Welding
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...
متن کاملAnalysis and Comparison of Friction Stir Welding and Laser Assisted Friction Stir Welding of Aluminum Alloy
Friction Stir Welding (FSW) is a solid-state joining process; i.e., no melting occurs. The welding process is promoted by the rotation and translation of an axis-symmetric non-consumable tool along the weld centerline. Thus, the FSW process is performed at much lower temperatures than conventional fusion welding, nevertheless it has some disadvantages. Laser Assisted Friction Stir Welding (LAFS...
متن کاملWelding Aluminum Alloy 6061 with Opposing Dual Torch Gtaw Process
Cracking is a major concern in welding aluminum alloys. Although weld solidification cracks can be eliminated through addition of filler alloy, the additives modify the alloy or base-metal constituents and may not always be desirable. High-energy beam processes, such as electron-beam welding, that result in minimal heat input reduce crack sensitivity, but their high cost limits their applicatio...
متن کاملThe Mechanical Properties Evaluation of the Welded Sheets of AA 3105 Aluminum Alloy Using Friction Stir Spot Welding (FSSW)
Friction stir spot welding (FSSW) is a type of solid state welding that is used in the connection of small pieces and light metals such as aluminum alloy especially. The technical problem during melting of aluminum alloys is one of the most important reasons for developing application of friction stir welding for aluminum alloys. In this research, the effects of important processing parameters ...
متن کاملEvaluation of Friction Stir Spot Welding Process by Laser Ultrasonic Method with Synthetic Aperture Focusing Technique
The application of laser ultrasonic technique is developed for evaluation of friction stir spot welding (FSSW) quality. The features of laser-generated ultrasonic waves in good welding and incomplete fusion area are simulated by finite element method (FEM). The non-contact laser ultrasonic inspection system (LUIS) was established to verify the numerical results. The interaction of laser ultraso...
