RG-45 - Oxy-Acetylene Carbon Steel Welding Rod (R45) - 36" x 1/16" (1 Lb);

RG45 is a copper coated low carbon steel rod which is widely used for oxyfuel welding on mild steel. It has good ductility and good machinability. Its typical minimum weld tensile strength is 45 ksi and it conforms to AWS A5.2 R45. RG45 can be used on steel plate, sheet and pipe where high strength is not required. While this alloy was originally developed and are commonly used for oxyfuel welding, they can be used for TIG welding. Flux is not needed but, "puddling" of the molten metal will bring any scale or impurities to the surface. Weld on clean base metal to ensure the best results. RECOMMENDED OXYACETYLENE PROCEDURE: Bevel cracks or heavy sections where possible. Clean the area to be welded as thoroughly as possible. Use a neutral or slightly reducing flame. The extent of the excess fuel gas is measured by the length of the "streamer" or "feather" of unburned fuel gas visible at the extremity of the inner cone. The "streamer" should measure about 1/8 to 1/4 of the length of the inner cone of the flame. Excessively long "streamers" should be avoided since they may add carbon to the weld metal. If forehand welding (welding rod precedes the torch flame), distribute the heat and molten weld metal by using opposing oscillating motions of the flame and welding rod. If backhand welding (welding rod is interposed between the flame and molten metal), then there is significantly less manipulation of the flame or welding rod.
