  1. 1. Adaptive Welding Trials – Into Robotic Systems : A pre-welding study to see the possibilities and challenges for adaptive welding implementation

    University essay from KTH/Produktionsutveckling

    Author : Holger Johansson; [2023]
    Keywords : ;

    Abstract : This diploma project investigates a practical approach to adaptive welding. The goal was to evaluate the possibility for implementation of adaptive welding, and the diploma work comprised theoretical work and evaluations of adaptive welding of one of the welds on a front frame.

  3. 2. 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

  4. 3. Fracture Simulation of Electrofusion Joining.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Amir Alizadeh; [2015]
    Keywords : ;

    Abstract : This Master thesis investigates mechanical failures of electrofusion joints. This type of joints are used for weld high density polyethylene pipe systems where tting and pipe will be welded together by the heat caused by the resistance of the copper cables to electric current.

  5. 4. Robotic 3D friction stir welding : T-butt joint

    University essay from Högskolan Väst/Avd för automationssystem

    Author : Cheng Zhang; [2015]
    Keywords : Friction stir welding; robotic friction stir welding; three-directional welds;

    Abstract : This Master Thesis was performed in terms of robotic three dimensional friction stir welding with T-butt joint. Friction stir welding (FSW) is a solid state welding method that achieves the weld temperature by friction of a rotating non-consumable tool with the workpiece. READ MORE

  6. 5. Weld optimization with new Low Temperature Transformation fillermaterials

    University essay from KTH/Industriell produktion

    Author : Gustav Schmidt; [2013]
    Keywords : ;

    Abstract : In this study, evaluation of typical weld geometry, residual stresses and fatigue properties of two new LTT consumables have been performed. The literature survey discusses the topics of LTT consumables regarding fatigue life, chemical composition, dilution, crack phenomena and fatigue crack repair, impact toughness, weld residuals stress and weldgeometry.
