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). Field Welding Inspection Guide - Pages(A709-Grade 36, 50, 50W) When the base metal temperature falls below 32 degrees F the base metal shall be heated to at least 70 degrees F. No welding shall be done when the ambient temperature around the weld joint is below 0 degrees F. Preheat can be checked by the use of a Tempstick. 9 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.)

As additional welding processes and consumables are evaluated, the HPS Fab Guide will be updated to include those recommended for welding HPS 70W steel. All references made hereafter to AWS D1.5 shall mean the AASHTO/AWS D1.5M/D1.5:2002 Bridge Welding Code. 1.1 Fabrication With HPS The superior toughness of HPS 70W steel, Just plain carbon steel What is it? - The FABRICATORMar 09, 2010 · The A709 Grade 36 is denoted as bridge material with the same basic chemical, mechanical, and physical properties. Carbon adds to strength and hardenability of steel. A36/SA36 is less than 0.30 percent carbon and will not harden appreciably. MIG wire for autobody work - Miller Welding Discussion Oct 14, 2009 · ASTM A709 grade 36 has a yield strength of only 36 ksi, but an ultimate tensile strength in the range of 58-80 ksi. A709gr30 would be more easily bent than A992, even though they have about the same ultimate tensile strength.
shall be ASTM A709 Grade 50 or 50W (AASHTO M270 Grade 50 or 50W). ASTM A709 Grade 36 (AASHTO M270 Grade 36) steel may be used for miscellaneous applications, such as, anchor bolts, expansion joints, rods etc. All miscellaneous steel hardware exposed to weathering action shall be galvanized. 6.4.3 Bolts, Nuts and Washers 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 a709grade 50w//a709grade 36 low alloy steel by Xinsteel a709grade 50w//a709grade 36 low alloy steel - Sell offer Click to View Original Image.
