  1. 21. Laser welding for battery cells of hybrid vehicles

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Adrián Ros García; Luis Bujalance Silva; [2019]
    Nyckelord :laser; welding; batteries; aluminium; keyhole; conduction; CO2 ND:YAG;

    Sammanfattning : The report is an overview article, as a result of our investigation at the field of laser welding applied to electromobility cells manufactured in an aluminium housing. This project was proposed by the University of Skövde in collaboration with ASSAR Centre. LÄS MER

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

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jimmy Holgersson; Klara Trydell; [2019]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  4. 23. Capturing Variation in Welding : A method to map variation in welding production, creating a basis for production improvements

    Master-uppsats, Karlstads universitet

    Författare :Lotta Månsson; [2019]
    Nyckelord :Variation; Weld; Laser scanning; Quality; Data display; Production improvement;

    Sammanfattning : Weld quality is essential when manufacturing fatigue-loaded structures. Defective welds are problematic, causing increased lead times, repairs and breakdowns. Over- processing as a result of unnecessary safety margins and poor quality is another issue, leading to a more expensive process and heavier products. LÄS MER

  5. 24. Lasersvetsning : En genomförbarhetsstudie av stora rotationssymmetriska komponenter med varierande materialsorter

    Master-uppsats, KTH/Industriell produktion

    Författare :Johan Nilsson; [2018]
    Nyckelord :;

    Sammanfattning : A big problem with welding is that it is hard to predict how a high heat canaffect different materials. The effects that can appear is shape changes in thematerial and brittle structures. The brittle structures will affect the strengthof the material and if the shape changes are big, the fatigue strength of thecomponents will be limited. LÄS MER

  7. 25. Innovative Methods for Welding Ultra High Strength Steel with Resistance Spot Welding

    Master-uppsats, KTH/Industriell produktion

    Författare :Rickard Aldén; [2018]
    Nyckelord :;

    Sammanfattning : 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.
