    Sammanfattning : Tandem gas metal arc welding (GMAW) is a high productivity welding process which is appliedin many industries. However, a type of imperfection, known as cold lap, was revealed thatmostly accompanies the tandem GMAW process. LÄS MER

  3. 3. Cold lap formation in Gas Metal Arc Welding of steel An experimental study of micro-lack of fusion defects

    Detta är en avhandling från Trollhättan : University West

    Författare :Peigang Li; Lars-Erik Svensson; Norbert Enzinger; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tandem GMAW; old laps; lack of fusion; Spatter; Overlap; Overflow; Manganese; Silicon; Oxides; Temperature; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Cold laps are defined as micro-lack of fusion defects at the weld toe more or less parallel to the surface of the parent plate. These defects are known to negatively influence the fatigue properties of weldments. Previous studies suggest that cold lap formation can not be avoided completely in Gas Metal Arc Welding (GMAW).
