High-speed friction stir welding in light weight battery trays for the EV industry
نویسندگان
چکیده
Present work aims to achieve high welding speed during friction stir of lightweight battery trays in the electric vehicle industry. This study reports high-speed (HSFSW) up 4.0 m min−1 AA6063-T6 alloys. The defect-free HSFSW joints are produced by adopting aggressive material mixing, i.e. higher tool rotation and plunge force. weld cross-section reported an unusual hardness profile ‘U’ shape instead ‘W’ conventional FSW AA6xxx resulted softening zone (∼60HV) along with HAZ (∼53HV) against base (BM) ∼90HV. at obtained good joint strength 71% BM. Microstructure evolutions across fractured discussed using EBSD analysis.

Optimization of Friction Stir Welding Tool Advance Speed via Monte-Carlo Simulation of the Friction Stir Welding Process
Recognition of the friction stir welding process is growing in the aeronautical and aero-space industries. To make the process more available to the structural fabrication industry (buildings and bridges), being able to model the process to determine the highest speed of advance possible that will not cause unwanted welding defects is desirable. A numerical solution to the transient two-dimensi...
متن کاملMisalignment detection for friction stir welding or Enabling seam tracking for friction stir welding
This paper describes a technique for determining the position of the friction stir welding (FSW) tool with respect to the weld seam during welding. This technique is proposed for online misalignment detection or as a position estimator for in-process tracking of the weld seam for FSW.
متن کاملFriction stir welding and processing
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 aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a de...
متن کاملReview: friction stir welding tools
Friction stir welding (FSW) is a widely used solid state joining process for soft materials such as aluminium alloys because it avoids many of the common problems of fusion welding. Commercial feasibility of the FSW process for harder alloys such as steels and titanium alloys awaits the development of cost effective and durable tools which lead to structurally sound welds consistently. Material...
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...
