To minimize heat affected zone cracking: Use a low hydrogen consumable, like a -H4 or -H2 Preheat. This slows the cooling rate. Note that excessive preheat may anneal the base material Slow cool welding astm a36 and preheatWelding ASTM A514 or A514M-05 steel? - The FabricatorAs manufacturers strive for lower costs and greater efficiencies, they tend to substitute high-strength materials for standard materials. One such high-strength material is ASTM A514/514M-05. Although it is not difficult to weld, joining it successfully requires paying close attention to the preheat temperature, interpass temperature, and filler metal.

Table 4.9 states in the footnotes that For ASTM A514, the maximum preheat and interpass temperature shall not exceed 400F for thicknesses up to 1-1/2 inches inclusive, and 450F for greater thicknesses. One final comment: Welding T-1 (ASTM A514) should not be complicated. Follow the recommendations above and avoid problems.Preheating can be critical to welding successPreheat a large enough area around the weld joint to ensure the proper temperature is maintained throughout welding. Preheating a wider area minimizes the risk of colder areas in the material sucking away the heat. Preheat measuring often is done with Tempilstik®s, infrared thermometers, or other heat-measuring devices.Preheat and Interpass Temperature for welding astm a36 and preheat - WELDING For ASTM A709 Grade HPS 70W and ASTM A852, the maximum preheat and interpass temperatures shall not exceed 400°F [200°C] for thicknesses up to 1-1/2 in [40 mm], inclusive, and 450°F [230°C] for greater thicknesses. The use of high heat input welding processes such as submerged arc welding (SAW) may allow for lower preheat temperatures
