I need to weld some brackets in a shipping container. There are some vertical joints and since the material is .065 wall I want to weld vertical down. I would like to use 6011 but I don't know if that electrode will work with the Corten material that containers are made of.

6011 works just fine, I've used it on containers myself. Built a jobsite fuel and lube service rig using a 20' can mounted on a set of Stellar roll-off rails. Mostly 6011 and 6010 work.
By the way, ventilate well when you weld inside them.

Ive added brackets to my container with both 6011, and 7014,never had any problems. Haven't found any cracking in the walls or ceiling, and nothings broken off, yet. I would favor the 6011 . It will perform even with a little rust, or paint still on the metal. Vertical down should go pretty quickly too...

It would depend on if your container or a customer container.

[QUOTE=Lis2323;8867882]Skip the welding. Lots of other pro looking options available JMHO of course
i avoided welding in mine, except for outer lock antitheft. alot can be done just using the fixed loops already there. mine is nice, luckily im close enough to the container dealers around the oakland ports, that i went and picked mine out. the price on them fluxuates as much as gasoline used too. dealing w/ them guys, is right down there w/ mobile home movers, auto junk yards, asphalt contactors, etc

add roofers to the list. My cop friend insists anytime an exceptionally heinous crime ( rape , murder) is committed the first thing they check is to see if the circus is in town.
Next on the list is roofing contractors as they attract a transient workforce.
Is vertical down considered acceptable for structural? Isn't it just for pipe?
All I remember is that in my community college course, the instructor said "there is no such thing as vertical down in the structural AWS code" -- only vertical up.
I have welded shelves and hangers in shipping containers we use on construction sites a bunch of times it's usually a down and dirty thing with 1/8 7018 or 3/32 if it's on the jobsite. This is not really code welding or welding to a print so i wouldn't say whatever gets you sound weld i would use mig or small flux core if I had it but we usually don't. Down beads are usually a very convex weld that's not particularly strong but 6011 can be run downhill easily so you just need to judge what is sufficient and meet whatever is on the print if there is one. The corten welds fine you will just lose the corrosion resistance in the weld zone so a good post-weld paint job is in order. I guess i would ask the question i usually ask is the a weld detail for this or do i just make it up for our sea container welding i already know the answer just weld the damn thing already. If you have any issues blowing through you need to back up and work it out. It has been said already but we often bolt and angle, or flat bar on the wall the container to weld hangers for leads, wire rope chokers, slings, and what have you to me that's a good practice.

Yeah, that makes sense, I guess I just always wondered WHY there was no "vertical down" in the structural AWS code. I mean, if it's going to be inspected and "test welds" will be destructively tested, what's the big deal? I don't think I ever asked the instructor that question... It makes me wonder whether "vertical down" can give welds that look good cosmetically but are no good underneath...

there is a clause in there, that allows downhill for ""fixing undercut ", and that is the only time downhill allowed. i been asked twice, in my time, by an inspector to do so
Downhill progression is approved for fixing undercut in D 1.1and for tube the welder can weld any direction they are qualified for. Downhill welds are also used in pipe welding and lincoln has the procedure in the book. I am not aware of any code that applies to welding brackets in a connex box. There are inspectors how have a real pet peeve with undercut so you have to accommodate them or fight with them which usually doesn't work out well. sometime with minor undercut you can just grind the base metal very lightly with a cut wheel at the toe of the weld and remove it without really digging in or disturbing the weld profile. There are some flux core wires that can't be welded vertical up and more that can't be welded vertical down. We had an issue with this on a job with brace tube where the inspector claimed he saw some downhill welding the Lincoln NR 200 series wire specs specifically stated all positions but vertical up but the inspector backed off when he was shown that tube can be weld in any position and progression for which the welder is qualified. Nobody wanted to show the inspector that the wire specs excluded uphill progression be we were all welding up except to fill some gaps before welding out.

If it's steel, use whatever rod you're comfortable with. Like Lis said, 6013 makes a prettier bead. 6011 will do just fine. With 0.065" wall thickness, you're going to want to use some pretty small rods. 3/32 is my go-to. 1/16" rods are really flimsy, so it can be sort of frustrating to re-strike an arc. You can get 5/64 rods, too. Might have to order them, depending on how well stocked your LWS is.

Vertical down doesn't have as much strength. Traveling down makes for a colder weld than traveling up.
Edit: I'm not saying it doesn't make for strong welds. Like Sberry said, if it's welded, it's welded. BUT if you weld two identical joints, one vertical up and one vertical down, then cut, polish, and etch them, the vertical up will have more penetration.
Well I will bet money that if they are welded in with 6010 or 7010 downhill you tear the cones and the brackets up before ukulele can get them off the wall properly welded downhill will work quit using 6011 and 6013 and you won’t have problems
