  1. 1. FE-model for prediction of welding distortions in components made of preformed stainless steel sheets

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Tom Glansholm; [2020]
    Nyckelord :Welding simulation; distortions; Ferritic stainless steel; EN1.4509; FEM; Solid mechanics; Residual stresses; Svetssimulering; deformationer; restspänningar; Ferritiskt rostfritt stål; EN1.4509; Finita elementmetoden; Hållfasthetslära;

    Sammanfattning : This master thesis was carried out at Scania CV AB. The focus for this thesis is the prediction of welding distortions that can cause problems in the manufacturing process of Scania's after-treatment system. The after-treatment system is mainly assembled by sheet metal plates of the ferritic stainless steel EN 1.4509. LÄS MER

  3. 2. A comparative study between conventional fixed and advanced adaptive control system for resistance spot

    Master-uppsats, KTH/Industriell produktion

    Författare :Caroline Bohlin; [2018]
    Nyckelord :RSW; Resistance spot welding; HCC; Heat Capacity Control; adaptivity; automotive;

    Sammanfattning : Resistance spot welding is the main welding method used in the automotive industry to weld thin sheet metal. Today adaptive control systems have been developed for RSW, which means it can adjust the parameters in the weld process automatically during welding. LÄS MER

  4. 3. Utveckling av lägesställare med tillhörande utrustning för svetsrobot : Undersökning av rotations- samt infästningsmetoder av schaber i rotationsfixtur

    M1-uppsats,

    Författare :Emil Olsson; [2018]
    Nyckelord :Maskinteknik; Rotationsfixtur; Schaber; Forshaga Svets Smide;

    Sammanfattning : This exam report includes a construction solution for further development of a schaberdressing process commissioned by Forshaga Svets & Smide. Schabrar are used in the manufacturing process of the paper industry. They are attached to a cylinder and are used to peel the paper off and also clean the cylinder. LÄS MER

  5. 4. 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

  7. 5. Manufacturing Effects on Iron Losses in Electrical Machines

    Master-uppsats, KTH/Elektrisk energiomvandling

    Författare :Konstantinos Bourchas; [2015]
    Nyckelord :electrical machine; induction motor; iron losses; relative permeability; guillotine; ber laser; CO2 laser; laser settings; cutting effect; welding; electrical steel.; elektrisk maskin; induktion motor; järnförluster; relativ permeabilitet; giljotin; fiberlaser; CO2-laser; laser inställningar; skäreffekt; svetsning; elektromagnetisk plåt;

    Sammanfattning : In this master thesis, the magnetic properties of SiFe laminations after cutting and welding are studied. The permeability and the iron loss density are investigated since they are critical characteristics for the performance of electrical machines. LÄS MER
