  4. Factors to Consider When Welding Dissimilar Strength ...

    An example here would be welding ASTM A572 Grade 50 to AISI/SAE 4140, in which the former material has both chemistry and mechanical requirements, but the latter has only a chemistry requirement. It is important to determine the weldabilty of dissimilar strength materials prior to joining them together for a number of reasons.

  5. Recommendations for Welding T-1 Steels, WELDING

    Depending on the grade this may vary by 25-50 ºF. Going by plate thickness, typical preheat temperatures would be as follows: Up to ½ 50-100F. Over ½ to 1 50-150F. Over 1 to 2 150F-200F. Over 2 200-250F. Please note that highly restrained joints may require higher preheat.

    4. For grades 50, 60 and 70, no preheat is required for temperatures above 0°F, provided low hydrogen conditions are maintained. For grade 80, at temperatures below 32°F, base metal should be heated to at least 70ºF. 5. More restrictive Charpy V Notch (CVN) values are available on an inquiry basis at additional cost. 6.
