The invention provides a welding control method and system. The method comprises the following steps: welding a weldment through a welding head; in the welding process, the deformation quantity and the welding energy of the weldment are continuously measured; a welding parameter comparison conclusion is obtained by comparing the relation between the deformation quantity and a deformation quantity threshold value and the relation between the welding energy and an energy threshold value, the deformation quantity threshold value comprises the highest deformation quantity and the lowest deformation quantity, and the energy threshold value comprises the highest welding energy and the lowest welding energy; and when the welding parameter comparison conclusion meets any judgment condition in a judgment condition set, welding is ended, and the judgment condition set at least comprises three or more judgment conditions set according to the deformation quantity threshold value and the welding energy.
