Abstract

The invention relates to an embedded linear friction welding joint defect control method and application thereof, and belongs to the welding manufacturing and repairing technology, and relates to connection or repairing of zero-allowance components. The defect control method comprises the steps that a process plate is fixed to the upper portion of a welded part in the wedge-shaped block entering direction, the process plate is attached to the welded part, and the angle of the welding end of the process plate is not smaller than that of the wedge-shaped block; and the wedge-shaped block installed at the vibration end is embedded into the welding part in the welded part, welding is conducted through a linear friction welding method, welding defects caused by the wedge-shaped block are left on the process plate, and the process plate is removed after welding. According to the method, when the linear friction welding is used for connecting or repairing long components, the joint quality can be ensured, and no defect exists in a welding seam.

Description

technical field [0001] The invention relates to the technical field of welding manufacturing, in particular to an embedded linear friction welding joint defect control method and its application. Background technique [0002] In the linear friction welding process, since a workpiece must be driven by the equipment to perform high-frequency reciprocating vibration during the welding process, a large pressure must be applied to both ends of the workpiece perpendicular to the friction surface, which determines to a certain extent that the workpiece at the vibration end should not be too large Or too long, which objectively limits the direct application of linear friction welding to the segmental welding combination of long members. US2004011241A1 discloses a friction welding joint device and a welding method. First, several parts of the elongated member are produced in sections. At the joints of the two sections, the opposite slope is processed into the same angle as the wedge,...
