FCAW or Flux Core Arc Welding Wire

E71T-GS Welding Wire	E71T-11 Welding Wire
Description: Designed for single pass applications, this flux core wire provides smooth arc action and full slag coverage. This welding supply accessory features self-shielding and low spatter that makes welding and slag removal quick and easy! From body work to thin alloy, this flux core welding wire will ensure high quality welding on a variety of applications. Self-shielding, all-positioning, flux-cored welding wire for single pass applications Smooth arc action full slag coverage Easy slag removal Low spatter	Description: E71T-11 Welding Wire is a general-purpose self-shielded tubular wire that is designed for welding thin guage mild or galvanized steel. Suitable for single or multiple-pass applications, especially for fillet and lap welds, you will get outstanding welding performance as E71T-11 produces a smooth spray arc-type of transfer with good wetting action. Great for welding outdoors or in drafty conditions, this all-position wire also provides very low spatter levels, resulting in a weld bead that is excellent in appearance. Produces smooth arc ation Full slag coverage Easy slag removal Low spatter

Often Asked Qustions

Q: About AWE classifiy numbers of E71T-GS and E71T-11 flux core welding wire, What do they mean?

Answer:

• E: Electrode
• 7: 70 ksi or 70.000 psi
• 1: All Position
• T: Tubular Electrode
• G stands for “general” classification. GS stands for general, “single” pass only applications.

These usability designators can be sub-divided into the two main categories of electrodes as follows:

• Self-Shielded, Flux-Cored Electrodes: T-3, -4, -6, -7, -8, -10, -11, -13, -14, -G, -GS
• Gas-Shielded, Flux-Cored Electrodes: T-1, -2, -5, -9, -12, -G, - GS

Q: What is the difference between E71T-GS and E71T-11?

Answer 1: E71T-11 must meet certain mechanical properties and must be capable of multipass . As already mentioned but Hankj a GS and G suffix means that properties are "agreed upon " so it can be anything. There is NO mechanical testing required ( tensile , yield, impact, elongation etc ) It does not mean that the electrode is no good , it just means it does not have to to through any testing and meet any criteria.

They're both 70,000 psi tensile yield strength. You would think, considering the AWS numbers (actually, that’s something that I’m not that clear on, from what I’ve read the flux core should be E7t-11, what’s with the 71?), but if you look up the actual numbers you’ll find that the flux core has a yield strength of 62-62K psi and the S-6 has a yield of 72-74K psi (when shielded with C25). There is also some weirdness with the ratings, it appears that you have to keep the flux core weld at 200* for 48hours to get that rating where I don’t see anything like that for the MIG wire. The strength at that level is a mute point. I’m not sure I’m following there. As far as I can tell both have a lower yield then the steel that I’m welding (for that matter most decent steel is at about what the S-6 is listed at or stronger), and since I really doubt that I’ll get full penetration I suspect that I can take all the strength that I can get up to the strength of what it is welded to. It would be personal preference, I would think. I like the .030" fluxcore for versatility/portability. Cleanup is an extra step, though. Personally, I’m liking the .030” fux core for a number of reasons (that and I promised to fix a friend’s trailer on the way which should be an easier job with flux core and prevents me carrying an 80 bottle with me), but I will not compromise strength for convenience on the other setup (it’s not like it’s a lives hang in the balance thing, I just do not want to do it again). You can eliminate a "V" if you gap the joint. You can still acheive 100% penetration from one side. yea, I realize that, and do it all the time, but in this case we’re talking some ½” plate, and there is no gap in the world that will allow me to make a proper weld to that with a HH135. A V will (or at least get me close) if I weave or make multiple passes. There is a second reason why I’m avoiding Ving it deeper or gapping the rest, and that is right now I’ve got about a 3/16”-1/4 surface below the V that is a perfect fit and holds the two in alignment. If I V further or gap I will have to make a jig to hold things which will at the very least be very awkward.
