This system features Adaptable Adjustable Pin Tool (AdAPT™) weld head technology, enabling it to perform self-reacting welds and join materials of varying thickness. The I-STIR PDS can support up to 5 DOF to produce welds with double curvature. The I-STIR PDS has successfully joined materials less than 1mm and up to 40mm in thickness. The I-STIR PDS Jr. solution is a single-axis system designed to perform linear welds. As a lower cost alternative to I-STIR PDS, this system features many of the same innovations as the PDS solution, such as AdAPT weld head technology. The PDS Jr. has been deployed to perform process research. The I-STIR™ 10 Gantry is a 5-DOF system capable of producing parts requiring multi-axis welding. This system features AdAPT™ weld head technology and a 10-ton forge load capacity, which is needed for thicker section welds and hard metals. The I-STIR Aero system is a 5-DOF system for use with thin-gauge aluminum alloys. Capable of pro- ducing high-speed welds of complex contours, this system features data collection of all critical param- eters so that Statistical Process Control (SPC) can be used to ensure quality. The system’s control software is compatible with most standard CAM programs. The I-STIR Aero system is also capable of performing basic machining tasks such as drilling, trimming and rough machining.

  • Friction Stir Welding of Aluminium Alloy AA5754 to Steel DX54
    Aalto University School of Engineering Department of Engineering Design and Production Hao Wang Friction Stir Welding of Aluminium Al- loy AA5754 to Steel DX54: Lap Joints with Conventional and New Solu- tion Thesis submitted as a partial fulfilment of the requirements for the degree of Master of Science in Technology. Espoo, October 27, 2015 Supervisor: Prof. Pedro Vila¸ca Advisors: Tatiana Minav Ph.D. Aalto University School of Engineering ABSTRACT OF Department of Engineering Design and Production MASTER'S THESIS Author: Hao Wang Title: Friction Stir Welding of Aluminium Alloy AA5754 to Steel DX54: Lap Joints with Conventional and New Solution Date: October 27, 2015 Pages: 100 Major: Mechanical Engineering Code: IA3027 Supervisor: Professor Pedro Vila¸ca Advisors: Tatiana Minav Ph.D. The demand for joining of aluminum to steel is increasing in the automotive industry. There are solutions based on Friction Stir Welding (FSW) implemented to join these two dissimilar metals but these have not yet resulted in a reliable joint for the automotive industrial applications. The main reason is the brittle intermetallic compounds (IMCs) that are prone to form in the weld region. The objective of this thesis was to develop and test an innovative overlap joint concept, which may improve the quality of the FSW between aluminum alloy AA5754-H22 (2 mm) and steel DX54 (1.5 mm) for automotive applications. The innovative overlap joint concept consists of an interface with a wave shape produced on the steel side. The protrusion part of the shape will be directly processed by the tip of the probe with the intention of improving the mechanical resistance of the joint due to localized heat generation, extensive chemically active surfaces and extra mechanical interlocking.

FSW is a solid-state joining process—a combination of extruding and forging—ideal for use when the original metal characteristics must remain as unchanged as pos- sible. During the FSW process, the pin of a cylindrical shouldered tool is slowly plunged into the joint between the two materials to be welded.

  • Evaluation of Optimization Parameters of Semi-Solid Metal 6063 Aluminum Alloy from Friction Stir Welding Process Using Factorial Design Analysis
    Journal of Manufacturing and Materials Processing Article Evaluation of Optimization Parameters of Semi-Solid Metal 6063 Aluminum Alloy from Friction Stir Welding Process Using Factorial Design Analysis Chaiyoot Meengam and Kittima Sillapasa * Department of Industrial Engineering, Faculty of Engineering, Ubon Ratchathani University, Ubon Ratchathani 34190, Thailand; [email protected] * Correspondence: [email protected]; Tel.: +66-453-53-343 (ext. 3373) Received: 9 November 2020; Accepted: 14 December 2020; Published: 17 December 2020 Abstract: The semi-solid-metal 6063 aluminum alloy was developed for the automotive industry. The objective of this research was to optimize parameters in friction stir welding process that can provide the highest tensile strength. The ANOVA factorial design was used to analyze rotation speed, welding speed, and tool geometry at different factor levels of experimentation. The results showed that the optimized tensile strength was 120.7 MPa from the cylindrical tool, rotation speed was from 1300 to 2100 rpm, and welding speed less than 75 mm/min in the coefficient of determination R2 was 95.09%, as can be considered from the regression equation. The examination of the stir-zone and thermal mechanical affected zone using SEM and EDX showed that the new recrystallization of the microstructure causes fine grain in the stir-zone, coarse grain in advancing-side thermal mechanical affected zone, and equiaxed grain in the retracting-side thermal-mechanical affect zone. The intermetallic compounds of β-Al5FeSi phase transformation phase were formed to three types, i.e., β”-Al5Fe, Mg2Si, and Al8Fe2Si phase were observed. Moreover, in the stir-zone and thermal-mechanical-affected zone, defects were found such as flash defects, void or cavity defects, crack defects, lack of penetration defects, tunnel defects, kissing bond defects, and dendrite formation defects affecting weldability.

The development of FSW technology in recent years has allowed a rapid increase in the understanding of the mechanism of this process and made it possible to perform the first welding trials of modern polymeric and composite materials, the joining of which was previously a challenge. The following review work focuses on presenting the current state of the art on applying this method to particular groups of materials. The paper has been divided into subchapters focusing on the most frequently used construction materials, with particular emphasis on their properties, applications, and usage of the FSW method for these materials. Mechanisms of joint creation are discussed, and the microstructure of joints and the influence of material characteristics on the welding process are described. The biggest problems observed during FSW of these materials and potential causes of their occurrence are quoted. The influence of particular parameters on the properties of manufactured joints for each group of materials is discussed on the basis of a wide literature review.

    International Research Journal of Engineering and Technology (IRJET) e-ISSN: 2395-0056 Volume: 06 Issue: 12 | Dec 2019 www.irjet.net p-ISSN: 2395-0072 REVIEW ON FRICTION STIR WELDING Tribhuwan Singh1, Shahzad Ali2, Kamal Kishor Sharma3, Gurudayal Kumar4 1Assistant Professor at IIMT Greater Noida 2Assistant Professor at NIET Greater Noida 3Assistant Professor at IIMT Greater Noida. 4Assistant Professor at IIMT Greater Noida -----------------------------------------------------------------------***-------------------------------------------------------------------------- ABSTRACT: Friction stir welding is an important new non-fusion technique for joining sheet and plate material. A rotating cylindrical tool with a profiled probe is fed into a butt joint between two clamped workpieces, until the shoulder, which has a larger diameter than the pin, touches the surface of the workpieces. Friction between the rotating tool and the plate material generates heat, and the high normal pressure from the tool causes a plasticized zone to form around the probe. The solid-state nature of FSW leads to several advantages over fusion welding methods, as problems associated with cooling from the liquid phase are avoided. Issues such as porosity, solute redistribution, solidification cracking and liquation cracking do not arise during FSW. Keywords: Welding, FSW 1. INTRODUCTION: 2.
