Section 255.237 - Preheating

(a) Carbon steel that has a carbon content in excess of 0.32 percent (heat analysis) or a carbon equivalent (C + 1/4 Mn) of 0.65 percent (heat analysis) must he preheated for welding.

(b) Carbon steel that has a lower carbon content or carbon equivalent than the steels covered by subdivision (a) of this section must be preheated for welding when preheating will alleviate existing conditions that would limit the welding technique or tend to adversely affect the quality of the weld.

(c) When steel materials with different preheat temperatures are being preheated for welding, the higher temperature must be used.

(d) Preheating may be accomplished by any suitable method, provided that it is uniform and that the temperature does not fall below the prescribed minimum during the actual welding operation.

(e) Preheat temperature must be monitored to ensure that the required preheat temperature is reached before, and maintained during, the welding operation.
