Weldability investigation of TStE 420 after weld thermal cycle simulationDunđer, Marko (Avtor) Vuherer, Tomaž (Avtor) Kladarić, Ivica (Avtor) HSLA steelsweldabilityweld thermal cycle simulationhardnessThe paper presents a short description and overview of the weld thermal cycle simulation methods. An experimental investigation on the weld cycle simulated specimens is predicted by a plan of experiment using single cycle simulation. The obtained hardness results are compared with double cycle simulated specimens results of individual points in the heat-affected zone. Beside that, the characteristic microstructures of points in the heat-affected zone after a single weld thermal cycle simulation are given. A thermal simulation method is suitable for different weldability examinations. In this paper, the authors would like to investigate the maximal hardness of individual points in the weld joint what is important when considering cold cracking sensitivity.20102012-05-31 14:38:33Neznano26675sl
