The temperature for welding carbon steel pipe varies depending on the specific welding process, but preheating is almost always required. A common preheat temperature is around 150°F (65°C), while other carbon steels might require between 32°F and 70°F (0°C and 20°C) depending on thickness and ambient conditions. High-temperature processes, such as those used for electric resistance or submerged arc welding, operate much hotter, at temperatures ranging from 1100°C to 1600°C (2012°F to 2912°F). Preheat temperatures For general carbon steel pipe: A common preheat temperature is around \(150^{\circ }F\) (\(65^{\circ }C\)), especially in colder environments.For thicker materials: Thicker carbon steel may require preheating to a higher temperature.Low-carbon steel (under 3/4 inch thick): This material can be welded at ambient temperatures as low as \(32^{\circ }F\) (\(0^{\circ }C\)), but if the ambient temperature is below \(32^{\circ }F\), a preheat to at least \(70^{\circ }F\) (\(20^{\circ }C\)) is necessary.For thicker materials (3/4 inch to 1 1/2 inch thick): A preheat of \(50^{\circ }F\) (\(10^{\circ }C\)) is often sufficient.
Weld-specific temperatures Electric Resistance Welding (ERW): Operates in the range of \(1100^{\circ }C\) to \(1300^{\circ }C\) (\(2012^{\circ }F\) to \(2372^{\circ }F\)).Submerged Arc Welding (SAW): Operates in the range of \(1200^{\circ }C\) to \(1600^{\circ }C\) (\(2192^{\circ }F\) to \(2912^{\circ }F\)).High-Frequency Induction Welding (HFIW): Operates in the range of \(1400^{\circ }C\) to \(1600^{\circ }C\) (\(2552^{\circ }F\) to \(2912^{\circ }F\)).
