英文摘要	A combined welding heat source model coupled by a flat gaussian and a cylindrical volume heat source was developed to analysis the evolution of welding-induced temperature, residual stress and distortion distribution during the processing of the flux band constraining arc (FBCA) welded T-joint of the -core sandwich. The experiment statistics were obtained by the infrared thermal imager and the three-coordinate instrument. By comparing the results between the experiment and simulation, it is found that the weld cross section, thermal cycle curves, welding isothermal curves and welding distortion are basically consistence between experiment and simulation, which proves the validity and feasibility of the combined welding heat source model on the analysis of this method. At the same time, it is found that the residual stress generated during the welding process is concentrated on the weld and its vicinity, which is much lower than the yield stress of the material. And the residual deformation is acceptable, that the maximum distortion happened on the edge of the panels, according to the experimental measurements. This indicates that the FBCA can effectively control the residual deformation of high-strength steel T-joints, which improves the welding technology for the sandwich panels. © 2020, Materials Review Magazine.
