    ASTM A572-50 Steel Manufacturing ... A572 Grade 50 has a smaller cross-section that can support the same or larger load than A36 steel or steels that are not structural grade. This directly correlates to the overall weight of the ramp where the higher the steel’s Yield Strength, the less the ramp can weigh. ... Welding wire for A572 Grade 50 ...

    Aug 01, 2006 · We are using a FCAW-G process with C25 shielding gas and an E71T-1 electrode. 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? 2) What is the best way to measure my preheat? 3) Do I need to monitor my interpass ...

    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. http://www.welding-advisers.com/
    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?

    May 27, 2009 · The yield and tensile properties for A572 grade 50 are 50 ksi and 65 ksi.... so the mechanical properties for A572 grade 50 meets and/or exceeds that of A36. Solid documentation of this can be supplied to the EOR with a copy of each ASTM standard, though, I can't believe an EOR wouldn't already know this.

    Jul 30, 2011 · I have a contractor that will be welding 0.50in. thick A572, Grade 60 plate that has to be welded to itself, to A36 and to UNS S3210 (unassigned)Duplex SS material.What precautions should they take when welding these materials. What welding rod should they use.It looks like 80ksi filler material should be used, preheat min. 50 F.

    Welding A 572 to itself and to A 36 carbon steel with the thickness stated above- minimum preheat 70 deg F, using SFA 5.5, E7018 H4 weld rod (SMAW process). The specified minimum YS for this rod is 60 Ksi. Keep the interpass temperature below 600 deg F. Now for the A 572 Grade 60 to the duplex, you need to use SFA 5.4 E309MoL weld rod. Minimum preheat as above, and keep the interpass temperature below 350 deg F.
    What is the material application and code of construction? I've been dealing quite a bit with these specific materials as of late, and various requirements and specifications, depending on project and industry, can drive you towards consumables other than those that metengr has suggested. Depending on code, there are some prequalified procedures that can often be taken advantage of using 80 series electrodes. Additional precautions can also be taken based on whether any supplemental requirements for the duplex are invoked.

    Please don't use 80-series filler. May cause problems, especially cracking if small root passes are made in cold weather. metengr's recommendations will develop the full strength of your 60-series material. He has given you very good advice.
    Duwe6: Please take a look at the AWS material groupings. If the OP is being driven by structural codes (D1.1 for example), and he or his contractor intends to use prequalified procedures, he would be required to run an 80 series filler (such as a Ni1) when welding the A572-60 to itself (Group III to Group III). For the dissimilar carbon steel welds, then I would agree with the 70 series recommendation. I've also been pushed to 80 series wires with processes other than SMAW when certain impact requirements were invoked that a 70 series wire couldn't meet. All dependent upon the application it's being applied to.
    For AWS D1.1 -- Prequalified WPS's, Mr168 is correct: Use 80-series filler, as per Table 3.1 For a WPS that you will be making a PQR coupon for, like all ASME [or for welding w/o a WPS] metengr and I are correct. Stay away from overmatching filler to basemetal. You will have cracking start at preheats that would have been sufficient with a matching filler.
