Joining of Aluminum and Steel in Car Body

Abstract Zinc-coated steel sheets have been joined with aluminum samples in an overlapping as well as in a butt-joint configuration. A bimetal- wire composed from aluminum and steel was used for additional welding experiments. An advantage of the laser-assisted bi-metal-wire welding is that the welding process is simplified since the primary joint between aluminium and steel exists already and Joining of Aluminum and Steel in Car Body Abstract Zinc-coated steel sheets have been joined with aluminum samples in an overlapping as well as in a butt-joint configuration.

Butt welding-brazing of steel to aluminum by hybrid laser-CMT

Oct 01, 2019 · Fronius CMT welding system and IPG YSL-4000 fiber laser system were used in experiments with a KUKA KR-60 six-axis robot as actuator. N. WuCurrent research status of dissimilar materials welding between steel and aluminum-welding characteristic, brazing and press welding. Welding and Joining, 03 (2010), pp. 5-12 Cold metal transfer (CMT) technology - A reviewKeywords:CMT, dissimilar welding. 1. Int roduction Fronius of Austria in 2004[7], after many years of research and development have unveiled new arc welding based on modified MIG welding process called cold metal transfer welding. CMT is a type of MIG welding process, but novelty is that Cold metal transfer (CMT) technology - An overview Feb 01, 2018 · The complex waveform of the welding current in the CMT process and the back feeding of the filler wire that mechanically forces the metal transfer make it difficult to understand the relation between welding parameters, metal transfer and heat transfer as shown in Fig. 2, which is studied by Mezrag et al. for Al 4043-S235 weld joint .With perfect arc length management and high edge

Current Research and Challenges in Innovative Technology

Current Research and Challenges in Innovative Technology of Joining DissimilarMaterials for Electric Vehicles:LI Hong 1, LIU Xusheng 1, ZHANG Yisheng 2, JACEK Senkara 3, LI Guangying 4, MA Mingtu 5:1 College of Materials Science & Engineering, Beijing University of Technology, Beijing 100124 2 College of Materials Science & Engineering, Huazhong University of Technology, Wuhan 430074 3 Distribution of Zn and Interfacial Microstructure of Braze In recent years, many scholars have done a lot of research on the CMT welding of aluminum and steel. The welded joints are divided into melting zone, interface zone, heat affected zone and zinc Effect of Brazing Flux Pb on Microstructure and Mechanical 5052 aluminum alloy and galvanized Q235 steel sheets with thickness of 1mm were lap welded/brazed by cold metal transfer technology (CMT) with ER4043 as the filler wire and Pb foil as the brazing flux. Scanning electron microscope (SEM), microscope with super-depth, X-ray diffraction (XRD), electronic universal tensile testing machine and hardness tester were employed to study the

Journal of Constructional Steel Research - Elsevier

The Journal of Constructional Steel Research provides an international forum for the presentation and discussion of the latest developments in structural steel research and their applications. It is aimed not only at researchers but also at those likely to be most affected by research results, i.e. designers and fabricators. Original papers of a high standard dealing with all aspects of steel Laser Welding under Vacuum:A Review2. The Research Status of Laser Welding under Vacuum Laser welding under vacuum or reduced pressure has a history of more than 30 years. As shown in Figure 1, the first report about laser welding under vacuum or under reduced pressure dates back to the 1980s. Arata et al.

made the research society to develop a new technology to exhibit better properties in dynamic conditions compared to the existing processes [1-3]. Finally, in 2004, FRONIUS came up with an idea of joining the aluminum alloys with a renowned MIG welding process known as Cold Metal Transfer (CMT) welding Microstructure and Bonding Strength of Aluminum Bronze Oct 23, 2018 · A cladding of aluminum bronze was obtained on the surface of medium carbon steel by CMT welding and short circuiting transfer welding. The microstructure of aluminum bronze and the interfacial microstructure of the interface between aluminum bronze and steel substrate have been systematically investigated. Sample 1-4 are + ( + 2 Microstructure and properties of aluminum AA6061-T6 to In this paper, two different aluminum alloy AA6061-T6 and pure copper T2 lapped joints were performed by CMT with AA4043 aluminum alloy wire as the filler metal. Results indicated that sound lapped joints between aluminum alloy AA6061-T6 and pure copper T2 could be performed by CMT technology.

Microstructure and properties of steel-aluminum Cold Metal

Mar 01, 2020 · The present paper investigates the relations between the welding speed and current waveform of the CMT process, and the characteristics of the steel-aluminum assemblies. Microstructural properties of the welds, as well as quasi-static and cyclic mechanical behaviors of the assemblies are analyzed and the optimum parameters giving the best On the Joint Formation and Interfacial Microstructure of Conventional CMT and CMT cycle step (CMT-CS) braze welding were carried out on the material combination of AA2024 T3 with a thickness of 1.27 mm and galvanized DP 780 steel sheet of 1.0 mm thick with a 10-µm-thick Zn coating on the surface. Al 4020 (EN ISO 18273) AlSi3Mn wire with a diameter of 1.2 mm was used as filler alloy.
