7018 storage

Postby mpete53 » Sun Apr 09, 2017 9:29 am

I have never used 7018 rod but want to give them a try. I keep reading about the need for a rod oven to keep it dry, but since 5lb of rod would last me a year or more that would not be practical. I was thinking about making a rod storage contained out of PVC pipe and rubber end caps to keep the moisture out and storing them in the house. Would this be enough to keep the rods fresh for a year?

Yes. I use the commercially available plastic rod holders with a rubber sealed cap to keep rod dry while it's on my truck.
I have more questions than answers

7014 is a very good alternative and no rod oven issues.

A screw cap rod container is only about $9 and all that is needed for most rods.
Your 7018 will still pick up moisture but it won't matter for home use on mild steel.
In my opinion.

Mark, I'm in Sennett, outside Auburn. If you're nearby you can swing by and get some 7018. I have 1/8" and maybe some 3/32" on hand.

If the 7018 has been exposed to air or dampness I notice more spatter and a somewhat rougher bead but I've never cut and etched a weld to check to see what the difference is in penetration. I have my 7018 rod (the remnants of a 50# can) in a big military surplus ammo can with desiccant bags. The bags get swapped out and dried in the oven every now and then. I also have a stainless steel 120 volt counter top convection oven in the shop like you sometimes see grocery stores making samples with. It gets to 550 degrees and I use it to dry the rods for anything other than a quick down and dirty weld.

If I was gong to weld anything truly structural I'd use fresh rod though.

Thanks for the reply's

I am a home welder and don't do serious structural work. I will pick up a plastic rod container and give them a try.

Lance, thanks for the offer but I am in Staten Island part of New York City.

Thanks again

Its per code you need to keep them in an oven, structural code I believe.

Since you are not doing structural code type work, you don't have to worry about it. That's where it comes from.

Any effort you make to keep them dry and such is not going to hurt them, it will only make it better. I have heard that when the can is opened its pretty much over and they start to absorb moisture. I guess the flux is rater hydroscopic so its bound to happen but by keeping them really hot in the oven, you make them low hydrogen again; which is what is required by code.

Home hobby use, don't even worry about it.

If you have a Harbor Freight near you, the orange plastic tubes are $4. They have a rubber seal, and even in the South Texas heat, they have yet to dry rot on me.

Yeah, I've got 7018 in those orange cans that have been in my garage for 5+ years and it welds just fine. I'm careful to keep the cans snugly closed, and when I need some sticks, I just very briefly open it and take out what I think I'll need.

I've got some 7014s on the go at the moment. They are very good. (This brand anyways.)

I was reading a post somewhere where a guy made his own holders out of plumbing pipe with a tubeless car valve on the bottom where he would put argon in the bottom via the valve and could open it to get out his rods as needed without the worry of any air or moisture being in there as is argon being heavier than air.
He would top up the argon every so often.
