  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. Characterization of Fiber Orientation and Weld Line Effects in Reinforced Plastics with Reduced CO2eq Emissions

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

    Författare :Anders Tolf; Markus Johannesson; [2022]
    Nyckelord :Fiber-reinforced plastics; GFRP; Reduced carbon dioxide equivalent materials; Experimental; Uniaxial tensile test; Uniform fiber orientation plate; Tensile strength; Fiber orientation; Weld line; Fracture analysis; Microscopy;

    Sammanfattning : With increasing emphasis and regulations on the environmental footprint in industries, the integration of reduced carbon dioxide equivalent (CO2eq) plastic materials is desirable. Fiber-reinforced plastic materials mechanical properties differ with varying fiber orientations. LÄS MER

  4. 3. Assessment of creep damage in Fe-Ni-Cr alloys

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Frans Sorsh; [2019]
    Nyckelord :;

    Sammanfattning : It is only a matter of time before components working in high temperature environments fail due to creep. Design for creep is therefore of vital importance to maximize the lifetime of components and reduce costs that may arise from maintenance and replacement of components. LÄS MER

  5. 4. Innovative Methods for Welding Ultra High Strength Steel with Resistance Spot Welding

    Master-uppsats, KTH/Industriell produktion

    Författare :Rickard Aldén; [2018]
    Nyckelord :;

    Sammanfattning : Resistance spot welding (RSW) is the most frequently used method for welding thin sheets in manufacturing industries such as the automotive industry, because of the high productivity of RSW. In order to reduce CO2 emissions the automotive industry strives towards creating structures of light weight, this is partly achieved by the use of lightweight materials such as Aluminum and composite materials.

  7. 5. Evaluation of current welding robot and improvement proposals for future use

    Master-uppsats, KTH/Marina system

    Författare :Joakim Nilsson; [2018]
    Nyckelord :;

    Sammanfattning : Welding of elements, a heat exchanging component, is one of the most essential processes during the manufacturing of Tubel evaporators. Weld joints consists of fillet welds of thin tubes against a plate on one end, and on the other end against a thicker pipe with entry holes for the tubes. LÄS MER
