  1. 1. Study of process parameters in laser beam welding of copper hairpins

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

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

    Abstract : 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. READ MORE

  3. 2. 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

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

    University essay from KTH/Industriell produktion

    Author : Rickard Aldén; [2018]
    Keywords : ;

    Abstract : 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.
