Beschreibung
Zusammenfassung:	The invention discloses a drawing process in nickel base welding wire preparation. The process includes the steps of conducting solution treatment and acid pickling on a wire with a diameter of 6.5 mm to form a wire with a diameter of 6.12 mm, conducting online treatment to form a wire with a diameter of 5.17 mm, a wire with a diameter of 4.85 mm and then a wire with a diameter of 4.27 mm, conducting online treatment to form a wire with a diameter of 3.31 mm and then a wire with a diameter of 2.79 mm, conducting online treatment to form a wire with a diameter of 2.3 mm, a wire with a diameter of 2.0 mm and then a wire with a diameter of 1.79 mm, conducting online treatment to form a wire with a diameter of 1.65 mm, a wire with a diameter of 1.5 mm and then a wire with a diameter of 1.4 mm, and conducting online treatment to form a wire with a diameter of 1.3 mm and then a wire with a diameter of 1.2 mm. By means of the process, the strength of 1100 MPa to 1300 MPa can be obtained, and the strength is uniform; the strength and winding of the welding wire are matched, and the welding wire has high straightness; the quality advantage that the surface of the welding wire is smooth can be achieved.
