  4. 3. Weld Quality in Aluminium Alloys

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Rujira Ninni Deekhunthod; [2014]
    Nyckelord :Weld Aluminium Alloys MIG MAG;

    Sammanfattning : The aims of this project are to present an understanding in what happens when aluminium-(Al) alloys are welded, and to investigate how the Mg-, Si- and Cr-contents in AA6005A influence the weld strength and cracking susceptibility. It is known that heat from welding affects the mechanical properties (strength) of the material. LÄS MER

  5. 4. MIG/MAG brazing with Cold Metal Transfer

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :MARIE ALLVAR; [2012]
    Nyckelord :CMT; Cold Metal Transfer; forceTIG; Plasmatron; brazing; arc brazing; laser brazing; automotive; zinc coated; galvanised; lap joint; CMT; Cold Metal Transfer; forceTIG; Plasmatron; lödning; båglödning; laserlödning; fordonsindustri; förzinkad; överlappsfog;

    Sammanfattning : In the automotive industry a commonly used material is thin steel sheets coated with a thin layer of zinc for corrosion resistance purposes. Welding of this material, with the high temperatures involved, causes problems with zinc burn-off leading to reduced corrosion resistance. LÄS MER
