effects of pass arrangement on angular Distortion Residual stresses and lamellar tearing tendency in thick plate t joints of low alloy steel
Journal of Materials Processing Technology, 2019Co-Authors: Chaohua Zhang, Suo Li, Long Hu, Dean DengAbstract:Abstract Three thick-plate T-joints with different pass arrangements were fabricated using low alloy steel. Experiments were conducted to measure the angular Distortion and Residual stress distribution of these T-joints. Based on ABAQUS code, a sequentially coupled thermal-mechanical finite element method considering moving heat source was developed to model the welding deformation and Residual stress distribution of the multi-pass T-joints. The evolution of the angular Distortion and stress distribution during welding process of the three T-joints was analyzed by means of numerical simulation. The peak stress distribution in the thickness direction of the flange during the entire welding process was examined based on the simulation results, and the lamellar tearing tendency of the T-joints was investigated. Among the three pass arrangements, the pass arrangement that welding passes are attached to the flange with surfacing welding produces the minimum angular Distortion and has the lowest tendency of lamellar tearing for thick-plate T-joints.

numerical simulation and experiment analysis of angular Distortion and Residual stress in hybrid laser magnetic welding
Journal of Materials Processing Technology, 2017Co-Authors: Youmin Rong, Jiajun Xu, Yu Huang, Haojie ZhengAbstract:Abstract Hybrid laser-magnetic welding 316L steel with butt joint was investigated. The bottom width of the bead profile was broadened from 1.606 mm to 2.492 mm, grain size was homogenized, and austenitic content was also improved. Considering the influence of magnetic field on bead geometry, a new simplified heat source model was developed and used to simulate temperature distribution. Integrating the steady magnetic field with laser welding, angular Distortion was reduced by 26.56%, the longitudinal Residual stress was smoothed, transverse tensile stress was cut down from 199.1 MPa to 167.3 MPa, longitudinal Residual plastic strain (−0.009) was homogenized to −0.007, and transverse Residual plastic strain was decreased from −0.08 to −0.075. The laser-magnetic welding was useful to homogenize the weld of bead geometry, microstructure, angular Distortion, Residual stress and plastic strain.
