Review on Multi-Pass Friction Stir Processing of Aluminium Alloys
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 22 July 2020 doi:10.20944/preprints202007.0514.v1 Review Review on Multi-Pass Friction Stir Processing of Aluminium Alloys Oritonda Muribwathoho1, Sipokazi Mabuwa1* and Velaphi Msomi1 1 Cape Peninsula University of Technology, Mechanical Engineering Department, Bellville, 7535, South Africa; [email protected]; [email protected] * Correspondence: [email protected]; Tel.: 27 21 953 8778 Abstract: Aluminium alloys have evolved as suitable materials for automotive and aircraft industries due to their reduced weight, excellent fatigue properties, high-strength to weight ratio, high workability/formability, and corrosion resistance. Recently, the joining of similar and dissimilar metals have achieved huge success in various sectors. The processing of soft metals like aluminium, copper, iron and nickel have been fabricated using friction stir processing. Friction stir processing (FSP) is a microstructural modifying technique that uses the same principles as the friction stir welding technique. In the majority of studies on FSP, the effect of process parameters on the microstructure was characterized after a single pass. However, multiple passes of FSP is another method to further modify the microstructure in aluminium castings. This study is aimed at reviewing the impact of multi-pass friction stir processed joints of aluminium alloys and to identify a knowledge gap. From the literature that is available on multi-pass FSP, it has been observed that the majority of the literature focused on the processing of plates than the joints. There is limited literature reporting on multi-pass friction stir processed joints. This then creates a need to study further on multi-pass friction stir processing on dissimilar aluminium alloys. -

Joining of AI-B4C Metal Matrix Composites by Laser Welding and Friction Stir Welding
Joining of AI-B4C Metal Matrix Composites by Laser Welding and Friction Stir Welding Dissertation Presented in Partial Fulfillment of the Requirement for the Degree of Doctor of Philosophy By Junfeng Guo UNIVERSITE DU QUEBEC A CHICOUTIMI 2012 Director: X. Grant Chen (UQAC) Co-director: Patrick Gougeon (NRC-ATC) Abstract AI-B4C MMCs are important materials as neutron absorber in spent nuclear fuel storage and transportation due to their high boron (10B) concentration and thus high neutron absorption capability. However, wide application of these materials is still limited due to the lack of suitable joining techniques to fully take advantage of the materials. Problems such as porosity and chemical reaction between Al matrix and B4C particles can arise during fusion welding of the material. Therefore, the present study is intended to find effective and reliable welding techniques for AI-B4C MMCs. The weldability of AA1100- 16%B4C (particle size: 11 pirn) and AA1100-30%B4C MMCs (median particle size: 15 pirn) was evaluated using laser welding and friction stir welding. In comparison with conventional arc welding techniques, the deep and narrow fusion zones associated with laser welding can result in smaller heat affected zones, and thus less thermal distortion and mechanical property degradation. On the other hand, friction stir welding, as a solid state process, seems promising as it can avoid various problems that may otherwise be encountered during fusion welding of MMCs. For laser welding without filler, it was found that most B4C particles were decomposed during welding leading to formation of needle-like AIB2 and AI3BC phases in the weld. -
Cold Metal Transfer Welding of AA1050 Aluminum Thin Sheets
ISSN 1517-7076 artigo 11730, pp.615-622, 2016 Cold metal transfer welding of AA1050 aluminum thin sheets Alaattin Ozan İrizalp 1, Hülya Durmuş2 Nilay Yüksel2, İlyas Türkmen2 1Celal Bayar University, Institute of Natural and Applied Sciences, Manisa, Turkey e-mail: [email protected] 2Celal Bayar University, Faculty of Engineering, Materials Engineering Department, Manisa, Turkey e-mail:[email protected]; [email protected]; [email protected] ABSTRACT This study was aimed to investigate the welding parameters on mechanical behavior of 2 mm thick AA1050 sheet materials joined by cold metal transfer (CMT) method. Macro structural examination showed that decreasing heat input decreased the pore size in the weld metal. Tensile test was applied and failure occurred in heat affected zone of aluminum sheet metal. Maximum tensile strength was found in the sample with minimum heat input. Heat affected zone was observed explicitly in the sample produced with the maximum heat input. Decreasing joint gap affected the bending strength positively. Bending strength was found superior with maximum bonding line length. Keywords: CMT welding, mechanical characterization, AA1050. 1. INTRODUCTION Arc welding of thin sheet aluminum alloys pose unique challenges. Due to comparatively high coefficients of thermal expansion and thermal conductivity when compared to steel, control of heat input to the weldments is a major prerequisite to avoid some problems such as burning through and distortion [1,2]. The benefits including thin heat affected zone, little distortion and improved productivity made the cold metal transferring (CMT) process incomparable when applied in welding thin plates and weld-brazing [3]. -
Effect of Focal Position Offset on Joint Integrity of AA1050 Battery Busbar Assembly During Remote Laser Welding
journal of materials research and technology 2021;14:2715e2726 Available online at www.sciencedirect.com journal homepage: www.elsevier.com/locate/jmrt Original Article Effect of focal position offset on joint integrity of AA1050 battery busbar assembly during remote laser welding * Tianzhu Sun , Pasquale Franciosa, Dariusz Ceglarek Warwick Manufacturing Group (WMG), University of Warwick, Coventry, CV4 7AL, UK article info abstract Article history: This paper aims at studying the impact of focal position offset on joint integrity of AA1050 Received 14 December 2020 battery busbar during remote laser welding. Welding experiments were conducted at Accepted 2 August 2021 different focal position offsets in the AA1050 L-joint with the integration of laser beam Available online 9 August 2021 oscillation. The impact of focal position offset was evaluated by multiple joint indicators including weld geometry, thermal profile, weld porosity and mechanical strength. Results Keywords: showed that defocusing of the laser beam tends to be favourable for the reduction of peak Remote laser welding (RLW) temperatures and weld porosity. However, a defocusing more than 3 mm can lead to 60% Battery busbar assembly drop in bonding integrity and 40% loss of joint strength. A tolerance window of [-2 1] mm AA1050 was determined for the focal position offset, corresponding to 70% and 30% of the Rayleigh Joint integrity length. This result is a useful reference to inform precise focal position control with respect Focal position offset to the accumulated variations of part tolerance, part-to-part gap and part positioning er- rors. This study also indicated that the thermal measurement can be a potential approach for in-process monitoring of joint integrity. -

Aluminium ALUMINIUM the RIGHT MATERIAL for OUR ENVIRONMENT
Aluminium ALUMINIUM THE RIGHT MATERIAL FOR OUR ENVIRONMENT ycle ec R M e l t The Life Cycle of Aluminium U s e te ica Fabr A complete life cycle material for the Consumer, Industry and the Environment. To ensure a high quality of life, the materials that we as consumers and manufacturers use, should meet not only technical performance standards, but have a long service life, be useable in a greater number of applications and be environmentally friendly. Once their service is complete, they should be 100% recyclable, thereby completing the life cycle to be used once again. Aluminium is such a material. ISO 9001 Lic QEC 3491 SAI Global Page 2 Welcome to Austral Wright Metals is the result of the merging, on 1st December 1997, of two long established well respected Australian owned metal distribution companies. Austral Bronze Crane Copper Limited (the metal distribution division of the Crane Group) and Wright and Company Pty Limited. This brought together Australia’s leaders in the distribution of: Copper, brass and bronze – sheet, coil, bar, rod, extrusions and tube. Stainless steel – sheet, coil, plate, bar, rod tube and fittings. Aluminum – sheet, coil, plate and tread plate. High Performance Alloys – including nickel based alloys, welding consumables and high technology metals. Austral Bronze Crane Copper was incorporated in 1914 to manufacture non ferrous sheet, coil and extruded product. The business was restructured in 1990 to clearly focus on the distribution of non ferrous and specialty metals. Incorporated in 1913, Wright and Company concentrated its efforts on the distribution of stainless steel and non ferrous alloys through its Australia wide warehouse network. -
