The invention belongs to the technical field of welding materials, and provides a high-efficiency preparation process of welding wire, which includes the following steps: (1) first solid solution treating the raw material; (2) sending it into a pickling pool for pre-pickling; (3) sending it into Drawing treatment by drawing machine; (4) Pickling, water washing and drying in sequence; (5) Ammonia decomposition heat treatment; (6) Sending to drawing machine for drawing treatment; (7) Pickling, washing and drying in sequence (8) Carry out ammonia decomposition heat treatment; (9) Send it to the drawing machine for drawing treatment; (10) Pickling, water washing and drying in sequence; (11) Send it to the drawing machine for drawing treatment; (12) Paint oil; (13) Straightening machine straightening; (14) Take-up. The invention reduces the breaking frequency of processing, and at the same time, for uniform strength, the strength of the welding wire matches the curvature, and has good straightness, and can obtain bright surface quality of the welding wire.
Description
technical field [0001] The invention belongs to the technical field of welding materials, and in particular relates to a high-efficiency preparation process of welding wire which increases the surface brightness of welding wire and has stable strength. Background technique [0002] At present, the processed welding wire is easy to break during the drawing process. The surface of the welding wire is blackened and blackened, and the surface finish is not high, resulting in a high defect rate. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency preparation process of welding wire, which can prevent fracture during processing, reduce stress, ensure the relaxed diameter and warping distance of welding wire, and improve production efficiency. [0004] A high-efficiency preparation process of welding wire of the present invention comprises the following steps: step (1) first solid solution treatment of raw materials; step (2) se...
