5 Methods to Determine Preheat Temperature WELDING

To see how these methods can vary we determined the necessary preheat for making a fillet weld on two 1.75-inch thick ASTM A572 Gr 50 plates.Results Manufacturers recommendation Arcelor Mittal states that for their ASTM A572 Grade 50 (BethStar&50) no preheat is necessary when the steels initial temperature is 0F or above.8.METALLURGY WELDING - SAC SteelCommentary The data given in Table 8-4 for A36 and A572 Grade 50 is somewhat weighted by the lighter,Group 1 shapes that will not ordinarily be used in WSMF applications.Excluding Group 1 shapes and combining the Dual Grade and A572 Grade 50 data results in a mean yield strength of 48 ksi for A36 and 57 ksi for A572 Grade 50 steel.A 572 Grade 50 - Miller Welding Discussion ForumsA 572 Grade 50 05-03-2011,06:49 AM.What P no.would I use to weld A572 Grade 50 steel?

Welding metals of dissimilar strengths

Consider a joint comprised of ASTM A514 steel that requires a 225-degree-F preheat and AISI/SAE 4140 steel that requires 600-degree preheat.Following the more stringent requirement (the 600-degree preheat) could prevent problems such as cracking,but it may also affect the integrity of the A514 steel.
