Interim Guidelines Advisory No. 2 SAC 99-01 Metallurgy & Welding 8-5 Table 8-4 Table 8.1.3-2 - Statistics for Structural Shapes1,2 Statistic A 36 Dual A-36/A572-50A-36/A572-50's strength, form-ability, and excellent welding properties make it suitable for a large variety of different applications. A-36/A572-50's yield strength is increased to 50,000 psi (higher than that of a normal A-36). Because of this, A-36/A572-50 is often used in structural applications that require higher strength than standard A-36.
A709 grade 36 low alloy steel plate is mainly used for built steel bridges.HSLA steel plate A709Gr.36 owned minimum yield strength at 250Mpa and tensile strength between 400 and 550 Mpa.For the delivery condition of steel plate A709 Grade 36,As rolled,Control rolled,TMCP with or without accelerated cooling,or quenching and tempering is all ok.Xinsteel stock different thicknesses low alloy APPENDIX F GUIDELINES FOR WELDING STRUCTURAL 2. Welding Operator - definition. a. A person who operates automatic welding equipment. b. Shop Welding Operator:(1) A person employed by the Contractor or fabricator to operate welding equipment in a fabrication plant. (2) Must be qualified by tests conducted at the plant and witnessed by an independent inspection agency. ASTM A36 steelASTM A36 Carbon Structural Steel Plate ASTM A36 steel plate is the most widely used hot-rolled steel product. As a kind of carbon structural steel product, its relative products are round rod steel, angle bar, and steel sections such as I-Beams, H-beams, angles, and channels.
Typically, for wind turbine towers DNV standards are invoked for design and AWS D1.1 is invoked for welding. RE:ASTM A709 - Preheat for Grade 50 brimstoner (Materials) it's neatly tucked away in Table 3.2 as a Category B preheat material, along with grades 36 and 50W. RE:ASTM A709 - Preheat for Grade 50 brimstoner (Materials) (OP) 28 May ASTM-A709 Standard Specification for Structural Steel Grade 50W [345W], or HPS 50W [HPS 345W] shall not be substituted for Grades 36 , 50  or 50S [345S] without agreement between the purchaser and the supplier. 1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. Bridge Plate MTR's - American Welding SocietyDec 29, 2008 · Topic Welding Industry / General Welding Discussion / Bridge Plate MTR's AASHTO M270 and ASTM A709 both contain structural steel for bridges in grades ranging from 36 ksi to 100 ksi. By Joseph P. Kane Date 12-24-2008 18:02 Eekpod You are wise to be aware that there can be a difference. I wouldn't worry about ASTM A-709 material where AASHTO
Jun 26, 2009 · Welding current. Some electrodes can be used with only AC or DC power sources while other electrodes are compatible with both. To determine the correct current type for a particular electrode, refer to the fourth digit of the AWS classification, which represents the type of coating and type of compatible welding current (see Figure 1). Filler Metals - Lincoln Electricdesigned for high speed, single pass welding on 12 gauge and thicker steels. (18) Innershield:NR-203MP, NR-203 Ni(1%), NR-232, NR-305, NR-311 Ni. (Exception:NR-311 Ni is not approved for use with any A709 grade when AASHTO/AWS D1.5 is appliable.) (19) Innershield:NR-203 Ni(1%). (21) For vertical down applications, NR-207 or Preheat and Interpass Temperature for - WELDING When the base metal temperature is below 32°F [0°C], the base metal shall be preheated to a minimum of 70°F [20°C] and the minimum interpass temperature shall be maintained during welding. For ASTM A709 Grade HPS 70W and ASTM A852, the maximum preheat and interpass temperatures shall not exceed 400°F [200°C] for thicknesses up to 1-1/2 in
