ABSTRACT:
A method for efficient production of a welding solid wire free of copper plating. The method consists of drawing by means of roller dies with the help of a dry solid lubricant for drawing which is at least either of sodium stearate or potassium stearate, removing the lubricant from the wire surface by means of a washing device, and applying a lubricant for wire feeding to the surface of the drawn wire by means of an oiling device. High-speed drawing by means of roller dies makes a stock wire into a welding solid wire having the diameter of the finished wire or nearly finished wire. The drawing step is followed by the washing step and the lubricant applying step, which are all accomplished in-line.
