  2. 11. Heat Transfer Prediction of In Service Welding in a Forced Flow of Fluid

    Author : Per Lindström; Lars-Erik Svensson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sjöfartsvetenskap; Maritime Science;

    Abstract : An algorithm for heat transfer prediction of in-service welding operations in a forcedflow of fluid is presented. The algorithm presented is derived from Rosenthal’s 3D heatflow equation and boundary layer approximations. READ MORE

  4. 12. Improved CWM platform for modelling welding procedures and their effects on structural behaviour

    Author : Per Lindström; Lars-Erik Svensson; Lennart Josefson; Hannu Hänninen; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CWM; FEM; WELD; STRESS; EPFM; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : A welding procedure specification is the document describing how a weld joint should be constructed. Arc weld processes are characterized by transient thermal behavior, leading to rapid changes in material properties and dynamic interaction between weld and base material. READ MORE

    Author : Tahira Raza; Joel Andersson; Lars-Erik Svensson; Boris Alexandrov; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser-Powder Bed Fusion; Alloy 718; Process Parameters; Heat Treatments; Weldability; Hot Cracking; Varestraint Testing; Laser-pulverbäddmetoden; Legering 718; Processparametrar; Värmebehandlingar; Svetsbarhet; Varmsprickor; Varestraintprovning; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Laser-powder bed fusion (L-PBF) is an additive manufacturing (AM) process that involves building components by fusing fine metal powders using laser. There is no universal set of process parameters that can yield optimum results for all the different materials, geometries, and L-PBF machines. READ MORE
