  1. 1. Resistance Element Welding of Ultra High Strength Steel to Aluminium

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Malte Eriksson; [2023]
    Keywords : ;

    Abstract : The automotive industry strives towards decreased vehicle weight in order to decrease green house gas emissions. To create lighter vehicles, new lighter materials need to be implemented. One issue with new materials is that the traditional joining methods in many cases meet their limitations. READ MORE

  3. 2. Methodology for Obtaining S-N Curves using Fatigue Testing and Static FEA

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Filip Anderfelt; David Äse; [2022]
    Keywords : Fatigue; Testing; Fatigue Testing; Test rig; Pneumatic; FEA; Weld; Steel; Fillet Weld; S-N curve;

    Abstract : The use of recommended S-N curves, presented in current literature, to analyse and determine the fatigue life of a part is common practice in, inter alia, the construction industry.However, the recommended S-N curves are generally created for larger components used in mainly the construction industry.

  4. 3. Fatigue analysis of laser welded hairpins in electric car motors

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Francisco Martín Ruiz; Imanol Iribar Rodriguez; [2022]
    Keywords : ;

    Abstract : Hairpins are copper filaments used in the windings in the stators of electric motors in modern times. For the motor to work, they have to be welded in pairs, normally with laser welding. Studying the fatigue response of the joint of hairpins welded with a set of values of laser welding process parameters is the main objective of this project. READ MORE

    Abstract : This report presents the degree project for a master's degree in Mechanical Engineeringat Luleå University of Technology performed by Emma Olsson at GKN ePowertrain in Köping. The aim of the thesis was to develop a calculation method to evaluate fatigue ina weld due to torsion. READ MORE

  6. 5. 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.
