Guide Slag Water Welded Plate Heat Exchanger for Steel WorksHow Does It Work? What Are The Different Types of Slag in Welding? Where Is It used? Advantages of Slag in Welding Disadvantages of Slag in Welding Frequently Asked Questions Conclusion Slag is the byproduct of some arc welding processes. It is formed during welding from flux. When the arc initializes and is stabilized, the filler metal of the electrode begins to liquefy and is deposited into the weld zone. Since the molten metal is fluid and has not cooled, it is much more prone to obtaining defects during the welding process and in the cooling period immediately afterward. Welding processes that utilize slag have electrodes that either have a flux coating ( See more on waterwelders WELDING OF UDDEHOLM TOOL STEELSON WELDING OF TOOL STEEL . Tool steel contain up to 2.5% carbon as well as alloying elements such as manganese, chromium, molybdenum, tungsten, vanadium and nickel.
