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

    Master-uppsats, KTH/Materialvetenskap

    Författare :Edwin Bergstedt; [2017]
    Nyckelord :Laser welding; AM50; Die Cast; Magnesium; Porosity;

    Sammanfattning : 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. LÄS MER
