  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

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Elias Ljunglöv; [2022]
    Keywords : stud bolt welding quality; accuracy in automated welds; welding unit fail-safe; brazed plate heat exchangers; programmable logic controller; human-machine interface; Technology and Engineering;

    Abstract : Today, the importance of sustainable and effective energy usage is rapidly growing. SWEP International AB leads the manufacturing of brazed plate heat exchangers that offer effective heating and cooling applications used in a wide range of systems and industries. READ MORE

  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

  5. 4. Techniques for Improving Weldability and Testing of Weld-bonded Joints

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Mattias Högsäter Myhr; [2020]
    Keywords : Adhesives; Automotive industry; Resistance Spot Welding; RSW; Weldability; Weld-bonding; Welding parameters; Fordonsindustri; Limning; Limpunktsvetsning; Motståndssvetsning; Punktsvetsning; Svetsbarhet; Svetsparametrar;

    Abstract : Increased understanding of improving the weld-bonding process is essential in order for the automotive industry to constantly develop their designs and production processes for the energy-efficient vehicles of the future. The joining method of weld-bonding, a hybrid method of adhesive joining and resistance spot welding, has introduced new challenges in the manufacturing and design of auto bodies. READ MORE

  6. 5. Characterization of the ethylene-vinyl acetate copolymer and the influencing parameters of the weld in intravaginal rings

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Ludwig Kaindl; [2020]
    Keywords : Ethylene-vinyl acetate; Intravaginal rings; DSC; Thermal properties EVA; Welding; Pharmaceutical Technology; Läkemedelsteknologi; Technology and Engineering;

    Abstract : The aim of this thesis was to characterize the mechanical and thermal properties of three different ethylene vinyl acetate (EVA) polymers with varying vinyl acetate (VAc) content and to investigate the influential parameters when welding the polymer into intravaginal rings. A second purpose in this study was to compare two different produced EVA polymers with the same VAc content to find thermal and structural differences. READ MORE
