The invention discloses a method for controlling reheat cracks in a welding heat affected zone of a structural component with the large restraint degree, and belongs to the technical field of weldingof structural components with large restraint degrees. The method for controlling the reheat cracks in the welding heat affected zone of the structural component with the large restraint degree comprises the following steps of 1, welding a first structural member and a second structural member, and connecting the first structural member and the second structural member through a welding joint to form the structural component with the high restraint degree; and 2, welding a remelting weld bead on the surface of the welding heat affected zone of the welding joint in the step 1. By adopting the method, the reheat crack tendency of the welding heat affected zone of the structural component with the large restraint degree can be reduced, reheat cracks in the welding heat affected zone of the structural component with the large restraint degree can be avoided or even completely eradicated, and the quality of the welding joint is improved.
