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

    University essay from KTH/Hållfasthetslära

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

    Abstract : 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. READ MORE

  3. 2. Evaluation of current welding robot and improvement proposals for future use

    University essay from KTH/Marina system

    Author : Joakim Nilsson; [2018]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 3. Optimization of the AdBlue e vaporation module for Scania V8 engines

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Mattia Antoniotti; [2017]
    Keywords : CR; evaporation unit; urea deposits; heat fins; Urea; förångningsmodulen; ureaavlagringar; rörflänsar;

    Abstract : The aftertreatment techniques introduced to follow the emission legislations require a constant improvement process to comply with the gradually more stringent demands. SCR is the system used nowadays to deal with NOx emissions in most heavy-duty vehicles. READ MORE

  5. 4. Modelling of the temperature field in TIG arc heat treated super duplex stainless steel samples

    University essay from Högskolan Väst/Avdelningen för maskinteknik och naturvetenskap

    Author : Chamara Kumara; [2016]
    Keywords : CFD modelling; Heat affected zone; OpenFOAM; Temperature field; TIG weld-ing; Phase transformation;

    Abstract : Super Duplex Stainless Steels have superior corrosion resistance properties and strength compared to conventional steels. However, these properties are influenced by the different phases that precipitate during the heat treatment process. READ MORE

  6. 5. Lubrication of the cutting tools in a stainless finishing line

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Johan Ek; [2016]
    Keywords : ;

    Abstract : In this thesis work the possible benefits of implementing a lubricant in the process of cutting stainless steel has been investigated. It has also be investigated how the lubricant could lower the wear rate in the cutting process. READ MORE
