  1. 16. Evaluation of material properties after laser welding on ductile cast iron

    University essay from KTH/Materialvetenskap

    Author : Olivia Taivalkoski; [2019]
    Keywords : Laser welding; ductile cast iron;

    Abstract : Scania wants to lower the weight of their trucks, including the goal to reduce the carbon dioxide emissions, and one way to do that is to use laser welding instead of fastenings.This bachelor thesis work is about laser welding of ductile cast iron, or spheroidal graphite cast iron or nodular cast iron, to QT-steels and case hardening steel and evaluation of the mechanical properties of the weld.

  3. 17. Pitting Corrosion Evaluation of Post-Weld Cleaning Methods for Stainless Steel Welds

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jimmy Holgersson; Klara Trydell; [2019]
    Keywords : ;

    Abstract : Welding stainless steel creates an oxide film, heat tint, on the surface and around the joint. It disrupts passivation and influence the corrosion resistance for the material. The result is often a decrease in pitting corrosion resistance for the joint and surrounding area. The heat tint is therefore commonly removed by post weld cleaning. READ MORE

  4. 18. Resistance Spot Welding of AlSi-coated Ultra High Strength Steel : An experimental study

    University essay from KTH/Materialvetenskap

    Author : Kristofer Hjelmtorp; [2019]
    Keywords : RSW; resistance spot welding; usibor; boron steel;

    Abstract : The automotive industry of today faces ever harder requirements from regulatory bodies to increase the fuel efficiency, reduce the carbon footprint and increase the safety of their vehicles. The problem is being tackled in different ways; one of them being the use of innovative materials to reduce the overall weight while improving the crash safety of the vehicle. READ MORE

  5. 19. Innovative Methods for Welding Ultra High Strength Steel with Resistance Spot Welding

    University essay from KTH/Industriell produktion

    Author : Rickard Aldén; [2018]
    Keywords : ;

    Abstract : Resistance spot welding (RSW) is the most frequently used method for welding thin sheets in manufacturing industries such as the automotive industry, because of the high productivity of RSW. In order to reduce CO2 emissions the automotive industry strives towards creating structures of light weight, this is partly achieved by the use of lightweight materials such as Aluminum and composite materials.
