Fu, J. (author), van Slingerland, J. (author), Brouwer, J.C. (author), Bliznuk, Vitaliy (author), Richardson, I.M. (author), Hermans, M.J.M. (author)Pulsed laser beam welding was used successfully to join the oxide dispersion-strengthened (ODS) Eurofer steel. The joining was conducted with a laser power of 2500 W and a pulsed duration of 4 ms. With the filler material being used, a minor material loss and microvoids were observed in the joint. The microstructure of the fusion zone...journal article 2020

Agarwal, G. (author), Kumar, A. (author), Richardson, I.M. (author), Hermans, M.J.M. (author)Solidification cracking susceptibility during laser welding was studied experimentally and numerically in advanced high strength steel sheets, namely transformation-induced plasticity (TRIP) and dual phase (DP) steel. Using the same heat input, laser bead-on-plate welding was carried out on single sided clamped specimens at various starting...journal article 2019

Gao, H. (author), Agarwal, G. (author), Amirthalingam, M. (author), Hermans, M.J.M. (author), Richardson, I.M. (author)Hot cracking during laser welding of Transformation Induce Plasticity (TRIP) steel at the edges of steel flanges can be a problem. In this study, modified hot cracking tests were performed by welding on a single-side clamped specimen at various distances from the free edge, while the heat input and external constraints remained constant. In situ...journal article 2018
