Design and Use of Cored Stainless Steel Electrode

摘要

Today, the use of cored wires in industry is widespread. Fabricators who compete on a global scale recognize the advantages of tubular wires not only in increased productivity, but also improved operability (ease of use) as compared to other consumable types, such as stick electrodes and solid wires. These features far overcome the higher cost per pound as compared to stick electrodes or solid wires. The same advantages, and others, also extend to cored stainless steel wires. The key to these advantages lie in the design of the wire. During the manufacture of stainless cored wires a continuous ribbon of flat, stainless steel strip is sent through a series of rolls that form it into a U-shape. This U-shape is then filled with powder and another set of rolls closes the U to form an O-shape. This O-shaped tube is then drawn through a series of dies to final size. The resultant product has a compacted powder center surrounded by a thin stainless steel sheath. The powder fill is either metallic (metal cored) or a mixture of metals and flux ingredients (flux cored).
