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.

From a welding stand-point, the specified upper limit on yield strength in ASTM A992 signifi-cantly reduces the possibility of the weld metal becoming under-matched. This in turn reduces the potential for brittle fracture. Also, ASTM A992 is a prequalified base metal per AWS D1.1:02 Table 3.1. Designers should specify it is be-

Understanding MIG Gun Liners BernardBirdnesting:If the welding wires path of travel through a MIG gun is blocked while the wire feeder is pushing it, a tangled mess of wire called a birdnest could be the result. A birdnest can be caused by a liner that is trimmed too short, clogged, or the wrong size (too small or large for the wire diameter).
Jul 10, 2008 SA709Grade 36 Liberia weldingnbsp; SA709Grade 36 Liberia welding#0183; SA709Grade 36 Liberia welding#32;Typically you'd use the same electrodes you'd use for welding A 36 to itself. A 36 is essentially the same as A 709 Gr. 36, so you can look up the tables in AWS D1.5. Another way to look at it is that A 709 Gr. 50 is essentially the same as A 572 Gr. 50, so if you have experience welding A 36 to A 572, it's the same as that. Hg
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
