This invention provides a non-contact, adjustable alternating magnetic field-eddy current coupled laser shock strengthening device and method for improving hydrogen embrittlement resistance. The device includes a laser shock strengthening unit, a magnetic field generating unit, a driving unit, and a position adjustment unit. The magnetic field generating unit has alternating N and S pole permanent magnets, which are driven to rotate by the driving unit. This induces an alternating magnetic field and closed eddy currents within the metal workpiece. The magnetic field strength, eddy current density, and temperature rise are synergistically controlled by adjusting the air gap and rotation speed. This invention couples a multi-directional alternating electromagnetic field during laser shock, promoting the activation of multiple slip systems and dislocation dispinning, improving the surface microstructure uniformity and residual compressive stress distribution, effectively inhibiting hydrogen intrusion and enrichment, delaying the initiation and propagation of hydrogen-induced cracks, and improving the workpiece's resistance to hydrogen embrittlement. The device has no contact electrodes and is suitable for complex curved surfaces and large-area workpieces.
