    • Root formation and mechanical properties in laser keyhole welding of 15 mm thick HSLA steel 

      Bunaziv, Ivan; Dørum, Cato; Nielsen, Steen Erik; Suikkanen, Pasi; Ren, Xiaobo; Nyhus, Bård; Eriksson, Magnus Carl Fredrik; Akselsen, Odd Magne (Peer reviewed; Journal article, 2021)
      Deep penetration laser welding is promising in joining thick (> 10 mm) steel sections. Focused laser beam by drilling vapour cavity, the keyhole, generates deep and narrow welds. Full penetration single-pass joining has a ...
    • Root formation and metallurgical challenges in laser beam and laser-arc hybrid welding of thick structural steel 

      Bunaziv, Ivan; Dørum, Cato; Nielsen, Steen Erik; Suikkanen, Pasi; Ren, Xiaobo; Nyhus, Bård; Eriksson, Magnus Carl Fredrik; Akselsen, Odd Magne (Peer reviewed; Journal article, 2021)
      Single-pass laser beam welding (LBW) of steel components with wall thickness of > 10 mm is of high interest due to enhanced productivity. Deep penetration LBW provides excessive hardness and certain quality issues such as ...
