  3. 22. 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

  4. 23. A Study in How Welding Parameters Affect the Porosity in Laser Welded High Pressure Die Cast AM50 Magnesium Alloy

    University essay from KTH/Materialvetenskap

    Author : Edwin Bergstedt; [2017]
    Keywords : Laser welding; AM50; Die Cast; Magnesium; Porosity;

    Abstract : There are a need for reducing the weight of vehicles, one solution is to implement cast lightweight materials such as the high pressure die cast AM50 magnesium alloy. The weldability of this cast alloy is poor and to implement the use of the alloy commercially a welding process is needed that limits the porosity of the weld. READ MORE

  5. 24. Defect formation in laser welded steels after use of corrosion protection coating

    University essay from KTH/Materialvetenskap

    Author : Elias Repper; Amanda Carsbring; [2017]
    Keywords : Laser welding; steel; porosity; mid-section bulging; defects; corrosion protection;

    Abstract : This bachelor thesis was made in collaboration with Scania. The objective was to find the cause for defects found in some rear axle welds. It was known axle material was coated with anti-corrosive oil. Oils were examined through ICP-AES, and then compared to the composition found on the surface of the steel samples. READ MORE

  6. 25. Evaluation of an External Axis for Tool Manipulation in Robotized Laser Beam Welding

    University essay from Högskolan Väst/Avdelningen för produktionssystem (PS)

    Author : Civan Ulucan Dayan; [2017]
    Keywords : Welding applications; manipulation; twincat; external axis; osition accuracy;

    Abstract : Laser beam welding applications are widely used in the industry. However, laser beam welding applications have a very small position tolerance to an offset. In this project, the offset is defined as the distance between the point, which the laser tool welds, and the point which laser tool should weld the weld joint. READ MORE
