    5/64" 7018

    Has anyone here used it? I have seem some talk of people on the web using it on thinner things like 14 gauge. I however can not find a supplier for it. I see hobart makes 1/16" in 1# packages but that is too small. Does anyone know where to find it? I have been told to use some utp612 because it is some kind of magic rod and I do have some and like it but it is just glorified 6013 and still has crappy dynamic load properties. Maybe I need more practice with 3/32 on 14 gauge but it is a bear it seems. Any one have any ideas?

    With other welding processes available to you why bother with 5/64 rods?

    What Jay said, either your 252 or little lincoln will be faster and way easier on 14 gauge than any stick electrode. I have never ran 5/64" 7018, but I have ran lots of 3/32" and its smaller than 5/64", and does pretty well down to 10-12 ga. or so.

    3/32 = 6/64, 6/64 > 5/64

    Tractor Supply and Sears sells 1/16" 7018 if you can't find 5/64" easily. That would be one alternative to 5/64" rods if all else fails. I know I saw someone selling 5/64" 7018 awhile back when trying to locate 1/16" 7018 for someone here, but I can't find that source tonight for some reason. I think Tractor Supply might have had 5/64" 7014 as another alternative for you.

    Re: 5/64" 7018

    Thanks for the replies guys. I was thinking more in line with 50# cans of the 7018. 3/32 7014 is probably what I will end up using since I can run it on thin stuff and it has the best mechanical properties of any non lo-hi rod. Why not wire feeds? I have a project coming up that will not fit in the shop and will have to build outside. It doesn't require a lo-hi process but I do want it to have welds that can handle some dynamic loading in sub zero temps. They don't make a flux core that is small enough with any ratings that would work on this thin. One other solution is to build it in pieces in the shop then assemble outside using sleeves in tubing which would behave as a backing and could then easily use the bigger rods. I could gas weld it I guess. Ha, that would probably be best solution for this situation. However for some field repairs it would be nice to have a smaller 7018 and I just wonder why no one makes them in larger packages of the various sizes.

    Since none of the major manufacturers offer 7018 in sizes smaller than 3/32, I am a bit suspicious of the quality of any 5/64 that you might find. Also it will probably be hard to find in packages larger than 1 or 2 lb.

    OTOH, while 6010 is not a low-hydrogen rod, it does meet low-temp. impact specs and is not too hard to use on thin material. You should be able to weld steel as thin as 16ga with a 3/32" 6010 at 50A or so.

    Also, even though the AWS specs for 6013 and 7014 do not include low-temp impacts, Lincoln's spec sheets for theirs (Fleetweld 37 and Fleetweld 47) do show CVN numbers at -20F.

    I was also thinking that the smaller rods would be questionable at best also. The hobart 1/16" are apparently made by a third party for hobart. I have looked at the numbers and and I know they list at -20 but at that temp the non lo-hi electrodes have very low numbers compared to any other process. In my experience the other processes and lo-hi are much tougher and less likely to crack from flexing. I was thinking more about gas welding it and many of the 14 gauge pieces will attach to 1/4" tube which will make the gas welding hard since I will likely warp the 1/4" badly. However runing the 3/32 would be easy except in the vertical which could equal blowing holes. How about 7016? Without the iron in the flux do these run a little cooler? Maybe 3/32 7016 could work? I can't say exactly what the project is but it is similar to a 6' tall truss that is 35' long but will not be loaded like a truss. However it will see cold temps and lots of flexing from wind. It could be over built and rid of all of these problems however the lighter material is perfect and allows less stress on adjacent structure. So how do 7016's compare?
