Preheat Temperature

The temperature to which many of the low alloy steels must be heated before welding. Preheating retards the cooling rate, allowing more time for the hydrogen to escape, which minimizes under-bead cracking. Preheat temperatures can vary from 10øF to 500øF on «? sections to 300øF to 600øF on heavy sections, depending upon the alloy.
