    • Application of laser-arc hybrid welding of steel for low-temperature service 

      Bunaziv, Ivan; Akselsen, Odd Magne; Frostevarg, Jan; Kaplan, Alexander F.H. (Journal article; Peer reviewed, 2019)
      Laser-arc hybrid welding (LAHW) is more often used in shipbuilding and oil and gas industries in recent years. Its popularity arises due to many advantages compared to conventional arc welding processes. The laser beam ...

    • Laser-arc hybrid welding of 12- and 15-mm 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, 2020)
      High-power lasers are very effective in welding of plates thicker than 10 mm due to the keyhole mode. High-power intensity generates a vapor-filled cavity which provides substantial penetration depth. Due to the narrow and ...

    • Porosity and solidification cracking in welded 45 mm thick steel by fiber laser-MAG process 

      Bunaziv, Ivan; Frostevarg, Jan; Ren, Xiaobo; Kaplan, Alexander F.H.; Akselsen, Odd Magne (Journal article; Peer reviewed, 2019)
      Porosity and solidification cracking in joining of thick sections are very common issues in deep penetration keyhole laser-arc hybrid welding (LAHW). In the present work, 45 mm thick high strength steel was joined by a ...
