Effect of preheating and preplaced filler wire on microstructure and toughness in laser-arc hybrid welding of thick steel
Bunaziv, Ivan; Langelandsvik, Geir; Ren, Xiaobo; Westermann, Ida; Rørvik, Gisle; Dørum, Cato; Danielsen, Morten Høgseth; Eriksson, Magnus Carl Fredrik (Peer reviewed; Journal article, 2022)Acicular ferrite (AF) is the most important microstructural constituent to achieve high toughness at low temperatures in weld metal of steels. This is due to the relatively small grain size and large misorientation angles. ... -
Numerical modelling of high-power laser spot melting of thin stainless steel
Bunaziv, Ivan; Danielsen, Morten Høgseth; Eriksson, Magnus Carl Fredrik; Ma, Xiang; Ren, Xiaobo; Godinez Brizuela, Omar Emmanuel; Skjetne, Paal (Peer reviewed; Journal article, 2023)Numerical modelling is an important scientific tool in laser materials processing to study different melting, evaporation, and solidification phenomena. It can assist in understanding why certain defects are formed, and ... -
Wire-arc additive manufacturing of structures with overhang: Experimental results depositing material onto fixed substrate
Evjemo, Linn Danielsen; Langelandsvik, Geir; Moe, Signe; Danielsen, Morten Høgseth; Gravdahl, Jan Tommy (Peer reviewed; Journal article, 2022)As additive manufacturing (AM) technology grows both more advanced and more available, the challenges and limitations are also made more evident. Most existing solutions for AM build structures layer by layer using strictly ...
