  • Finite element modelling of submerged arc welding process for a symmetric T-beam = Modeliranje postopka obločnega varjenja pod praškom simetričnega T-nosilca z metodo končnih elementov
    Culha, Osman
    Metallurgical welding joints are extensively used in the fabrication industry, including ships, offshore structures, steel bridges and pressure vessels. The merits of such welded structures include a ... high joint efficiency, water and air tightness, and low fabrication costs. However, residual stresses and distortions can occur near the weld bead due to localized heating by the welding process and subsequent rapid cooling. This paper is focused on deriving a simulation solution to predict the design parameters, such as the temperature-stress distribution, the approximate gradient and the nodal displacement on the plates during the process of submerged arc welding (SAW). During the construction of an AH 36 quality T-beam profile using the SAW process, thermal residual stress and distortion occurs due to heat fusion from the source to the joint part of the symmetric T-beam. The value of the design parameter is achieved by performing a thermal elasto-plastic analysis using finite-element techniques. Furthermore, this investigation provides an available process analysis to enhance the fabrication process of welded structures.
