welding a572 grade 50 to a36

ASTM A36 versus ASTM A572 GR50 American Welding

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.Welding metals of dissimilar strengths The FABRICATORUnfortunately, welding AR plate to softer or lower strength steels (usually A36 or A572) brings with it the potential for cracking in the heat affected zone (HAZ) of the AR plate. Here, you need to use a joint design such as a short, small fillet weld that can reduce heat input and overall residual stresses on the AR plate, and also find a 8. METALLURGY & WELDING SAC SteelExcluding 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. It should also be noted that approximately 50% of the material actually incorporated in a project will have yield strengths that exceed these mean values.

The weld to the 6" diameter shaft should be post weld heat treated. Successful welds can beIf this is a rotating part, PWHT!!!Yes, fillet welding to the plate. It only pivots or turns to fold up the machine for transport purposes. The shaft is greatly over sized and not asThe plate will then be removed after transport? If so, I would not PWHT, espeacially with a torch. I might give it a dehydrogenation treatment thouNo, I was mentioning why it probably wouldn't need to be heat treated or hardened there after the pin always stays in the joint and only rotatesAssuming that the "pin" is the shaft and is lightly loaded, the 8620 to carbon steel weld need not be subject to PWHT. A 300 F preheat is recommendThanks I guess backing up a bit, if hardness and wear isn't an issue, but just want something relatively strong to weld to using typical wireI have given you the welding filler metal with the SMAW "stick" process. Do you intend to use another welding process? If so, which process will yuPreferably weld with a MIG and wire. So recommended gas mixture and wire.As others noted you can weld 8620 round bar to A36 mild steel plate if you use the proper filler wire, preheat, etc. But it would not be practicalA572 Grade 50 ABER STEEL GRADEASTM A572 50 plate has a higher yield and tensile strength than A36 plate, combined with a lower weight. A572 50 plate is ductile and easy to form. It can be successfully machined with the appropriate techniques and is easy to weld.

A572 gR.50 steel APPLICATIONS ASTM A572 Grade 50 is considered a "workhorse" grade and is widely used in many applications.ASTM A36 Carbon Steel vs. ASTM A572 Grade 50 :Both ASTM A36 carbon steel and ASTM A572 grade 50 are iron alloys. Both are furnished in the as fabricated (no temper or treatment) condition. They have a very high 99% of their average alloy composition in common. For each property being compared, the top bar is ASTM A36 carbon steel and the bottom bar is ASTM A572 grade 50.5 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. ResultsManufacturers recommendationArcelor Mittal states that for their ASTM A572 Grade 50 (BethStar® 50) no preheat is necessary when the steels initial temperature is 0F or above.

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.8. METALLURGY & WELDING SAC SteelCommentaryThe 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.
