  1. 1. Projection Nut Welding to High- and Ultra-high Strength Steels

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Love Englund; [2023]
    Nyckelord :mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

    Sammanfattning : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. LÄS MER

  3. 2. Wheel Loader Rear Axle Mounting for Weld Deformations : Exploration and Evaluation of Alternative Mounting Methods

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Frans Forsberg; [2023]
    Nyckelord :Product Development; Weld Deformation; Design for Manufacturing; Reverse Engineering; 3D-scanning; Wheel Loader;

    Sammanfattning : Welded structures susceptible to weld deformations require sequent processing to allow for mounting of precision components. This thesis includes a case study of the rear axle mount on a Volvo L220 wheel loader. LÄS MER

  4. 3. Wire and Arc Additive Manufacturing : Topology Optimised Vehicle Component

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Malte Petersson; [2022]
    Nyckelord :Wire and Arc Additive Manufacturing; Additive Manufacturing; WAAM; AM; Overhang; Cooling times; Simulation; Welding;

    Sammanfattning : Wire and arc additive manufacturing (WAAM) is a manufacturing method using a numerical controlled motion system and a welding system to additively manufacture three dimensional components. The motion system is programmed from three dimensional computer aided design model data (3D-CAD) of the intended geometry which is then sliced in to layers and welded on additively. LÄS MER

  5. 4. Study of process parameters in laser beam welding of copper hairpins

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Dan Lönn; David Spångberg; [2022]
    Nyckelord :Laser Welding; Hairpin Welding; Copper Laser Welding; Process Parameter; Multi-Physical Simulation; Computed Tomography Scan; Design of Experiment;

    Sammanfattning : This study had the purpose to further the use of industrial lasers in the manufacturing of hairpin electric motors by optimizing the process of contacting the hairpins. A problem with laser beam welding of copper is the porosity created in the process which can lead to increased resistance of the welded region along with degraded mechanical properties. LÄS MER

  7. 5. Optimization of a welding gun use case by using a time-based ergonomics evaluation method

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Elia Mora Quiles; [2022]
    Nyckelord :Human Factors; Time-based ergonomics evaluation method; Digital Human Modelling DHM ; Ergonomics; Productivity; Optimizations; Simulation;

    Sammanfattning : Nowadays virtual simulations are commonly used to solve problems regarding worker well-being or productivity in manufacturing companies. However, when it comes to finding a solution to one of these two objectives, the other usually tends to be secondary. LÄS MER
