Steel Welding Techniques

Steel Welding Techniques Points : Steel Welding Techniques and Precautions Gas welding of carbon steels is extremely mostly confined, as other fuel gases generally do not give an enough sum of heat. An oxyacetylene flame has a hotness of up to 63 00°F (3482°C). Neutral flame is use for welding carbon steel. Through using a faintly reducing flame amplifies welding speeds are feasible. This kind of flame carburizes kerfs surfaces thus the heating lowers the melting temperature and creates possible the fusion of the deposit metal. Welded joints finished by this procedure are of high excellence and the fusion zone is not hard or brittle. Welding rods use have about 0.15% to 0.20% carbon and other metallic elements that will assure freedom as of included oxides with give the molten metal correct fluidity.
