Embodiment Construction
[0020] The present invention will be further described below in conjunction with the steps and the experimental data table. The high-strength welding wire manufacturing process includes welding wire smelting, off-line pickling, welding wire drawing, welding wire copper plating, welding wire layer winding, and the intermediate link of welding wire drawing is adding welding wire annealing process.
[0021] In the research on the necessity of welding wire annealing, the mold ratio used in the rough drawing and the fine drawing used in the annealing process without welding wire are shown in the attached figure 1 And attached figure 2 shown. The actual situation of the rough drawing process is recorded as: when the drawing reaches the specification of 3.85mm, the semi-finished welding wire appears shiny; when drawing to the specification of 3.55mm, the center of the welding wire cracks; more. The actual situation of the fine drawing process is recorded as: the welding wire cann...
