A reinforcing method of soft iron using laser is provided to reinforce the base steel plate, reduce the weight of the base steel plate, and be easily applicable to various base steel plates by densely irradiating a laser beam onto a base steel plate to be reinforced, thereby forming a heat treatment line on the base steel plate. A reinforcing method of a steel plate using laser comprises forming a linear weld penetration pattern, which is penetrated in the base steel plate by a laser beam irradiated by a laser irradiation part, on the surface of a base steel plate so as to reinforce stiffness of the base steel plate, wherein the weld penetration pattern is formed in a spring coil shape to provide the base steel plate with dense stiffness. A reinforcing method of a steel plate using laser comprises forming a linear weld penetration pattern, which is penetrated in the base steel plate by a laser beam irradiated by a laser irradiation part, on the surface of a base steel plate so as to reinforce stiffness of the base steel plate, wherein the weld penetration pattern is formed in a zigzag shape to provide the base steel plate with dense stiffness.
