*Preheat is not generally necessary except to be sure that work is in room temperature range 25-45C. However, preheat of 120-240C may be necessary to prevent heat affected zone cracking on high carbon steel or low alloy steel base metals. If more than two layers must be used, or if cross checks must be eliminated, preheat to 650C. Prolonged or repeated heating of manganese steel base metal over 260C can cause embrittlement and spalling. Avoid base metal embrittlement by limiting the temperature 12mm away from the weld to 260C and minimizing the time at elevated temperatures.
