High-strength aviation H18CrMoA automatic welding wire machining method

The invention aims to provide a high-strength aviation H18CrMoA automatic welding wire machining method. The method is characterized in that the machining method comprises the steps of alloy smelting, forging, steel rolling, wire rod hot rolling, surface treatment, primary cold-drawing, annealing treatment, polishing and burnishing treatment and secondary cold-drawing, wherein a H18CrMoA automatic welding wire is formed by subjecting a hot rolled wire rod to stagewise cold-drawing, the hot rolled wire rod is drawn to phi 1.2-10 mm through primary cold-drawing, then the annealing treatment and polishing and burnishing treatment are conducted, secondary cold-drawing machining of the subsequent pass is conducted afterwards, and the effect that the total reduction is greater than or equal to 80% when the hot rolled wire rod is drawn to the finished product size through secondary cold-drawing is ensured. 本发明的目的在于提供种高强度航空用H18CrMoA自动焊焊丝加工方法，其特征在于，所述加工方法为：合金冶炼，锻造，轧钢，热轧盘条，表面处理，初冷拔，退火处理，抛磨处理，二次冷拔；其中，H18CrMoA自动焊焊丝采用热轧盘条
