Bridge steel plate is specially used for erecting railway or highway bridges. welding of a 572 grade 50, bridge steel plate is required to have high strength and toughness to bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate used for bolt welding bridge should also have good welding performance and low notch sensitivity.
A572 Gr.50 steel pipe is a kind of high strength low alloy niobium vanadium structural steel in American standard ASTMA572/A572M-07.The welding of A572 Gr.50 steel pipe has the tendency to harden, it is easy to produce cold crack, and the toughness of heat affected zone decreases, so A572 Gr.50 steel pipe is sensitive to welding heat input.

A992, grade 50 welding of a 572 grade 50 Steel Material Types - Definitions A572 Grade 50 uses combinations of columbium, vanadium, and/or nitrogen to provide strength. Formability is good. Welding in the low and medium carbon grades is excellent. Used in transmission towers, auto parts, and truck trailers. M33 = Commonly known as Max 33 for its maximum carbon consistency of .33. Used in applications where physical and welding of a 572 grade 50
metal or the weld, the weld may be the lower strength element. For example, A572 Gr. 50 with matching strength E70 filler metal may have matching, undermatching or overmatching rela-tionships, based on actual properties. In theory, specified service loads would be limited to some percentage of the minimum specified yield or ten-Table 2. Search - Hobart Brothers Performance Welding Products 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.

Factors to Consider When Welding Dissimilar Strength Carbon welding of a 572 grade 50 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. Base Metal Grouping for Welding Procedure and Performance welding of a 572 grade 50 This publication is an extract of AWS B2.1/B2.1M:2014 , Specification for Welding Procedure and Performance Qualifi- cation , and is identical to Annex C, Base Metal Grouping, in the 2014 edition of that standard.
A572 gr. 50 is a micro alloyed columbium-vanadium steel grade having wide applications in ship building, bridges, oil/gas vessels, offshore structures, agricultural and construction machines etc.. As per the applications and requirements, welding process can provide desired bond between surfaces ASTM A572 welded with E71T-1m FCAW - American Welding Society The M indicates that it's for mixed gases. E71T-XM is a prequalified filler metal (Table 3.1) for A36 and A572 Grade 50 base metals, as long as the 572 is Grade 42, 50, or 55. I assume that you have Grade 50, which is the most common in structural applications. If it were Grade 60 or 65, that would complicate things a little. ASTM A572 Grade 50 Steel Equivalent, Gr 65, 60 Properties welding of a 572 grade 50 ASTM A572 Grade 50 Steel. ASTM A572 grade 50 steel is a low-alloy high-strength structural steel with a yield strength of 50 ksi (345 MPa) and a tensile strength of 65 ksi (450 MPa). It has better mechanical properties than ASTM A36 steel. ASTM A572 contains 5 yield point grades: Grade 42, Grade 50, Grade 55, Grade 60 and Grade 65.
E. ASTM A572 Grade 50 (50 ksi min yield) 1. High Strength Low Alloy Columbium Vanadium Steel Plates, Shapes and welding of a 572 grade 50 SEEK ADVICE BEFORE SPECIFYING WELDING DETAILS ON welding of a 572 grade 50 Welding metals of dissimilar strengths Some standards specify the chemistry properties required for certain material grades; other standards give mechanical property requirements; and some standards give both. For instance, you may need to weld 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 welding of a 572 grade 50 Welding ASTM 572 grade 65 - CR4 Discussion Thread At that time, we even detected cracks on tubular support structures (T-K-Y joints) made of pipes material. All are ASTM A572 material (if not mistaken is Gr 50). The repairs later are monitored fully using heating element, close monitor of WPS and Inspections by welding inspectors and UT & MPI carried out later after 72-hours minimum.
