A572 Gr 50 preheat question - American Welding Society

Yes you are reading it right.The preheat temperature has to be 150 degrees 3" (I think that is what it is)in all directions from where the weld is.Seems like alot of heat but it is the same way if you have a 3/8 plate going onto a 1"3/4 plate .It is sad but true.Welding 4140 to A572 Gr BMar 26, 2015Preheat RequirementsMar 04, 2009A572 gr 50 - American Welding SocietyMar 10, 2008See more results

ASTM A572-50 Steel Manufacturing - Copperloy

A572 Grade 50 has a 139% greater Yield Strength than A36 steel. A572 steel does not require preheat or post heating during the welding process and standard AWS D1.1 welding standards apply. Higher grades of steels will require preheating which is not economical compared to savings in weight.

Welding A572 Gr 50 - Welding, Bonding & Fastener ...

eng-tips› …› Welding, Bonding & Fastener engineering ForumAug 01, 2006· All plates are A572 Gr 50. My AWS charts recommend a 50 F preheat for this thickness. My questions are: 1) Should I be using a higher preheat since my joint is highly restrained? ... Preheat should be verified with Temp sticks or a portable contact pyrometer to assure preheat and also to monitor maximum interpass temperature. 3. You need to ...Steelforbrains; I can tell from your questions that you obviously do not have a qualified weld procedure for this job, and from my perspective this would seriously concern me. A 572 is a high strength low alloy modified structural steel. A-36 is structural steel. Have you sized your welds properly for this application? Do you intend to perform nondestructive testing after welding? The answers provided below will not be all inclusive, and you should seek professional assistance in developing a suitable welding procedure specification for this job. The following below should answer most of your questions; 1. I would recommend a minimum preheat of 150 deg F for all welding. 2. Preheat should be verified with Temp sticks or a portable contact pyrometer to assure preheat and also to monitor maximum interpass temperature. 3. You need to establish a maximum interpass temperature to minimize distortion during welding, and to avoid adverse effects on base metal toughness for the A 572 material from too much heat input. 4. Yes, I would recommend a post weld heat treatment after all welding is completed to reduce harmful residual stresses from welding for this application. Get some professional help in assuring proper design of the welds (size) and development of a qualified welding procedure using the suggested base materials.Another process problem for this kind of part is that you will have to stagger the weld around the part avoiding the weld pull. You will have to do sections of weld on alternating sides of centerline and probably on alternating sides of the ring to avoid excessive weld distortion.With reference to your requirement to case harden, it would not be an easy thing to do. Flame and induction case hardening depend on carbon content of the steel. Low carbon steel would not harden appreciably. Resorting to carburizing requires a large carburizing furnace. Quenching from austenitizing temperature is not an easy feat for those dimensions, and distortion is likely to be important. Depending on the actual requirements of your construction, if you need only certain surfaces hard, maybe thermal spray or hardfacing would provide the hardness you want. welding-advisers/I have designed many built-up structural rings of various configurations. Normally I use such rings in the design of large diameter storage tanks, bins and silos. Never have I had to use full penetration welds to join the components. Double fillet welds normally suffice for my applications. Can you re-evaluate the need for such heavy welds?
