| Abstract: | The mechanical properties of the Al–Si coated press-hardened steel (PHS) welded joint can be significantly deteriorated, and the desired fully martensitic microstructure can be decomposed by the introduction of aluminum into the molten pool during laser welding. In this work, a non-contact static magnetic field was introduced into the laser wire filling welding process to obtain uniform aluminum distribution, which in turn significantly improved the joint's tensile ductility and microstructure. The results showed that the tensile elongation of the magnetic field-assisted laser-welded joint was improved from 4.37% to 9.01% under a magnetic flux density of 100 mT, in which the fracture location shifted from "weld fracture" to "base metal fracture." Due to the interaction between thermoelectric currents (TECs) induced by the Seebeck effect and the magnetic field, the flow behavior of the liquid metal melt was modified. As a result, the coarse blocky ferrite affected by aluminum enrichment in the weld fusion line area was transformed into finely dispersed ferrite. In addition, the dislocation density was increased, and microstructural uniformity was enhanced. [ABSTRACT FROM AUTHOR] |
