Topic Welding Industry / Technical Discussions / A709 Gr.50 vs A588 By sbruno Date 08-31-2005 22:44 Can A588 be subsituted for A709 Gr. 50 in a D1.5 bridge PQR plate. By CHGuilford Date 09-01-2005 10:15 A588 is equivalent to A709 Gr 50W. The A709 Gr 50 is equivalent to A572 Gr 50.
AASHT M270-50 Material, anyone familier w/ it??Jul 04, 2008 SA709Grade 50 Togo weldingnbsp; SA709Grade 50 Togo welding#0183; SA709Grade 50 Togo welding#32;ASTM A 709 Gr. 50 is basically A 572 Gr. 50 plus Charpy requirements. A 709 and M 270 explicitly state that particular grades meet or exceed the requirements of A 36, A 572, A 588, A 992, etc. D1.5 discusses the AASHTO SA709Grade 50 Togo weldingamp; ASTM specs. D1.1 doesn't mention AASHTO specs at all; I guess they figured only the bridge people would ever be messing
AWS D1.1 lists minimum preheat for Pre-Qualified WPS's with ASTM A709 Gr 50 3 to 20 mm inclusive = 0 degrees C (if base metal is less than 0 it shall be preheated to 20 degrees C minimum) Over 20 mm through 38 mm inclusive = 10 degrees C Over 38 mm through 65 mm inclusive = 65 degrees C Over 65 mm = 110 degrees C Hope that helps, Regards, DD
ASTM A709/A709M-18 - TechstreetGrade 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.

Guide to Industrial Aluminum WeldingAug 24, 2020 SA709Grade 50 Togo weldingnbsp; SA709Grade 50 Togo welding#0183; SA709Grade 50 Togo welding#32;The thickness of aluminum in industrial welding applications typically ranges from 1/8 inch to 16 gauge, but you may be welding up to 3/8 or 1/2 inch in some cases. Gas and filler metal selection, as well as proper technique, may differ depending on the material thickness and the goals of
heat treated, length restrictions of 50 ft. (15.2 m) max. may apply); widths to over 150 in. (3.81 m) depending on overall weight; refer to ArcelorMittal USA Plate offices. Welding Because HPS 50W is produced to a lower carbon content than 50W, it is expected to be
How to Weld Aluminum:The Beginners GuideJun 15, 2020 SA709Grade 50 Togo weldingnbsp; SA709Grade 50 Togo welding#0183; SA709Grade 50 Togo welding#32;Laser beam welding is great for fast, clean welds and is ideal for materials sensitive to cracking, such as aluminum. Resistance welding:This type of welding joins metals by applying pressure and passing current through the metal areas being joined. It can be used for aluminum, however the welder must be aware of the high thermal and

Dec 21, 2006 SA709Grade 50 Togo weldingnbsp; SA709Grade 50 Togo welding#0183; SA709Grade 50 Togo welding#32;The selection of PWHT should be 1100 deg F, which is about 50 deg F less than the original fabrication heat treatment (min 1150 deg F) for this material. You need to use low hydrogen weld electrodes and keep the interpass temperature during welding at or below 450 deg F. Your preheat should only be 150 deg F if at or under 1.5 in plate
