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

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Malte Eriksson; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

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

    Sammanfattning : 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. The influence of modelling variables in FEM evaluation of fillet welded structures

    Master-uppsats,

    Författare :Marko Cordasic; [2020]
    Nyckelord :;

    Sammanfattning : Valmet is a world leading company in the pulp-, paper- and energy industry and is a manufacturer of e.g. paper machines. These paper machines are largely composed of steel frames for which beams and plates are often joined by welding. LÄS MER

  5. 4. Modelling, Evaluation and Assessment of Welded Joints Subjected to Fatigue

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Prajeet Rajaganesan; [2020]
    Nyckelord :Welded joints; Fatigue Assessments; Hot Spot method; Python Automation; Post-processing; Abaqus;

    Sammanfattning : Fatigue assessment of welded joints using finite element methods is becoming very common. Research about new methods is being carried out every day that show a more accurate estimation of the fatigue life cycle than the previous ones. LÄS MER

  7. 5. Evaluation of Shunt Distance in Resistance Spot Welding

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Daniel Fredriksson; Milou Carlfors Göransson; [2020]
    Nyckelord :Resistance spot welding; RSW; Shunt effect; Shunting; Shunt distance; One-dimension welding lobe; Punktsvetsning; RSW; Shunt effekt; Shuntning; Shuntavstånd; Endimensionell svetslob;

    Sammanfattning : The purpose of this study was to generate a greater understanding of how the shunt distance affects the shunting phenomena which occurs when working with resistance spot welding (RSW). Shunting affects the quality of the weld and the goal of the study was to create guidelines for RSW to minimize its impact on the weld quality. LÄS MER
