  1. 1. Evaluation of welding joint methods for a prismatic battery cell module

    University essay from Lunds universitet/Innovation

    Author : William Hellingwerf; [2021]
    Keywords : Aluminium welding methods; Battery module; Prismatic cell; Weld strength; Weld analysis; Weld temperature simulation; Technology and Engineering;

    Abstract : Prismatic battery cells swell due to a number of different factors, such as state of charge, temperature and irreversibly with charge cycling. Cell health can be improved by restricting the swelling of the cell, and therefore, the container which holds the cells, the module, should be able to restrict the swelling, and thus withstand the force exerted by the cells.

  3. 2. Alternative welding methods for nitrogen alloyed steel

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Anders Bertilsson; [2017]
    Keywords : Nitrogen alloyed tool steel; Uddeholm Vanax SuperClean; solid-state welding; direct-drive friction welding; friction stir welding; microstructure; Vickers microhardness testing; retained austenite measurement by X-ray diffraction; Kvävelegerat verktygsstål; Uddeholm Vanax SuperClean; trycksvetsning; friktionssvetsning; friktionsomrörningssvetsning; mikrostruktur; Vickers mikrohårdhetsmätning; restaustenitmätning med röntgendiffraktion;

    Abstract : This project explores the feasibility of the solid-state welding method direct-drive friction welding to be used as a joining method for the nitrogen alloyed steel Uddeholm Vanax SuperClean, produced via processes based on powder metallurgy. Vanax SuperClean cannot be welded using fusion welding methods where the base material melts, due to nitrogen escaping the material, resulting in inferior quality welds. READ MORE

  4. 3. Robotic 3D friction stir welding : T-butt joint

    University essay from Högskolan Väst/Avd för automationssystem

    Author : Cheng Zhang; [2015]
    Keywords : Friction stir welding; robotic friction stir welding; three-directional welds;

    Abstract : This Master Thesis was performed in terms of robotic three dimensional friction stir welding with T-butt joint. Friction stir welding (FSW) is a solid state welding method that achieves the weld temperature by friction of a rotating non-consumable tool with the workpiece. READ MORE

  5. 4. Design of Gas Shield for Friction Stir Welding Machine

    University essay from Linköpings universitet/Maskinkonstruktion; Linköpings universitet/Tekniska fakulteten

    Author : Henri Pehkonen; [2014]
    Keywords : ;

    Abstract : The research and development of the final disposal of the nuclear waste produced by the nuclear power plants is an important work done by The Swedish Nuclear Fuel & Waste Management Co. (SKB). As the demands on a final disposal increase the laboratory equipment has to be better in order to do valid experiments. READ MORE

  6. 5. Slow strain rate testing of welded copper

    University essay from KTH/Materialvetenskap

    Author : Kirti Teja Pasupuleti; [2013]
    Keywords : copper canister; friction stir welding; slow strain rates; creep test; knock-mecking model;

    Abstract : In Sweden spent nuclear fuel is planned to be placed 500 m down in the bedrock. The spent nuclear fuel will be contained in copper canisters. The reason behind the selection of copper is its thermodynamic stability against corrosion in the depository. The copper will be exposed to mechanical loading and will be plastically deformed due to creep. READ MORE
