O/T Welding Oil Feild Pipe

Royboy · Jan 16, 2015

Looking to build my G/daughter a "T" type swing set for her as well as for adults. I was thing of usinf oil pipe 3". My question is can I weld it with a Lincoln A?C buzz box and use 6013 or 6013. Planning on a6' or 8' crossarm. Thanks

Bad choice of rod for something that might hit your ghrandaughter on the head if it breaks. I don't know the composition of oilfield pipe but I would use 6010 and top it with a nice pass of 7018 .

LAA · Jan 16, 2015

I'm sure you can weld it with your rig, a lot of used oil field pipe is magnetized. I personnaly would not fool with it, most areas where there is used oil field pipe available their is also plenty of new ''reject'' pipe available, just as cheap or cheaper.

jon f mn · Jan 16, 2015

I don't see any reason why you can't do it your way. More important than specific welding methods would be a properly designed structure and if you post some drawings of what your doing I would be happy to offer advice to make sure your design will hold up. 6010 and 7018 are dc only rods unless you buy the special 7018ac.

Hank ABAB · Jan 16, 2015

E7018 can be used on AC or DC.
The reason you have trouble welding with it on your "buzzbox" type AC Welder, is because it has a very low OCV (open circuit voltage). Check it out on your NAMEPLATE.

If you would have a better AC welder with a higher OCV, it will work just fine.

The E7018 that is sold for use on an AC machine, is more expensive and contains more "arc stabilizers" in the coating. That is why this electrode works better on your AC machine.

I have welded a bunch of new oil field 4" and 6" pipe. I used 7018. I wouldn't know why the 6013 would not work though. The thing to remember when joining to pieces put the end of your bare rod between the two pieces for a gap. I did it mostly in the air with the pipe in hangers. I didn't have a pipe welding vise to hold the ends so I clamped a piece of angle iron to hold it in place before starting to weld to get it held in place.

old · Jan 16, 2015

My self I would use 7014 rod with a good grinding of the metal to make sure you have a good weld. Or if your good at welding the 7018 is also very good but I say 7014 because not all guys can strick and arc well

PJH · Jan 16, 2015

I know nothing about your structural design, or your welding skills, but yes, it can be welded with your Lincoln welder and 6013.

Pete Hall · Jan 16, 2015

Yep 6013 good for AC machine
Don't worry about breaking if you get good penetration!!!!!!
Ac not my choice of welding but Ive seen a lot of 6013 welded on Ac machines
I would trust MY life on IT
Ive worked in 3rd world countries with AC welders only and it does WELL
Go for it!!!!
7018 is better but Very hard to weld in AC mode

Pete Hall · Jan 16, 2015

7014 is flat position rod only,very hard to use on ROUND pipe
Yes it puts out a pretty weld
Not my choice for this application

Been using it for 40 plus years and never yet had any problems with it and done tons of welding jobs

IH2444 · Jan 16, 2015

(quoted from post at 14:31:34 01/16/15) I know nothing about your structural design, or your welding skills, but yes, it can be welded with your Lincoln welder and 6013.

Yep I have welded many things including tractor drawbars and such with 6013 and have yet to have one break. And yes I have even ran with scissors! I have even welded cast iron exhaust manifolds with 6013 and they held forever as far as I know.

Pete Hall · Jan 16, 2015

Old,
Hey Ill give it a shot
I love 7014 but in industry welding they frowned on 7014 for anything but flat welding
Ive welded 40 years also but I learn EVERY day
any secrets on different positions??
Thanks
Pete

old · Jan 16, 2015

I am a believer in high heat settings so that you get good penetration. On most of my welds you can look at the back side of the weld and see right where the bead was laid. A good friend of mine who was a pipe line welder told me years ago 7014 works well for most jobs and most of the time when I weld things I can move it around so I do most of the welds with the project laying flat. and another key is grinding it the correct way

Ron in NS · Jan 16, 2015

Here is what I usually refer to.
electrode guide

Pete Hall · Jan 16, 2015

Old
Yep,I too have best luck moving around to get best position
not always possible
Like I said I learn every day
Thanks

I started out welding when I was 15 or 16. Got one of them $19.95 Lincoln welder you saw in the Popular Mechanic's mags back in the early 70. What a piece of junk it was but it did weld sort of. Then when I was in the Navy one of my friends was a Hull teck so he taught me how to weld.

Pete Hall · Jan 16, 2015

Old
I was a millwright for 30+ years and done my share of welding
Thank you for your insight on 7014
I will try using it more as I told you before,
I love the flow and ease it welds
Just never thought of it as all purpose
As I said before,I learn every day!!!!

Bayou Dave in Ms · Jan 16, 2015

Laa is correct, not only is a lot of used oilfield pipe magnetized, but more than likely radio-active to some degree. Can be demagnetized by wrapping the hot lead? around the pipe while welding if I recall correctly.

Ultradog MN · Jan 16, 2015

One thing that has not been addressed here is that a lot of oil field pipe is highly magnetized - depending on what it was used for.
Magnetized pipe can be welded but you might get a lot of arc blow. The arc will walk off in odd directions.
It can be welded though. If you get a lot of blow try taking your ground lead and wrap a couple/few wraps around the pipe you are welding.
If it blows worse, wrap it the other direction.
Experiment with it.
I welded a lot of oilfield pipe and that is how we did it.

old · Jan 16, 2015

Never been a mill right but was a maintenance man at Tracker Marine back in the late 80s where I learned to mig and tig weld. Had a number of months where I worked the night shift so had lots of time to stand around and play so started playing with soda cans and tig welding and after a while got to where I could weld on up and hold water. after I had cut it in half then welded it back together.

old · Jan 16, 2015

Some of the newer 7018 AC rod is getting to the point it is pretty easy to weld with. Me I pretty much keep 2 types of rod on hand 7014 and 7018. Lots of stuff I weld I do put my life on the line since I build a lot of deer stands from scrap iron

Pete Hall · Jan 16, 2015

Your a better welder than me old
I am Very good at Mig but never could see that puddle in the TIG welding
I still appreciate the info on 7014
Im going to play more with that
You say run her HOT?
I love this site!

old · Jan 16, 2015

Ya run hot. I run it at 135-150 amps on 1/8 inch and up. I make a lot of deer stands out of old water pipe and bed frame and what we call slick rod and most of it as been done with 7014 and I have 22 or so stands and same are 20 plus years old and still holding up just fine

RodinNS · Jan 16, 2015

On a crackerbox I'd use 6011 for the root pass and 7018AC for the surface pass... That's more or less what they do in the field.
Leave the 6013 alone.

Rod

Pete Hall · Jan 16, 2015

Darn it old
Bed frames that's some hi carbon steel
I still appreciate the info
I am going to try more of this 7014
Still the best lookin weld

If its strong
I want to LEARN
Im not being a smart ---
Just interested!!!!!!
pete

Ron in NS · Jan 16, 2015

7014 is all position rod.
7024 is for use in flat or horizontal positions only.

The 1 signifies all position
The 2 signifies flat or horizontal positions only

shaun wallace · Jan 16, 2015

I have seen a lot of 2 3/8 and 2 7/8 with a lot of paraffin buildup. And radioactive from rust which is not harmfull if left in open for awhile.

old · Jan 16, 2015

I understand where your coming from. My friend who was a pipe line welder/instructor. Was the one who told me to go with 7014 and use a high heat.
As for my deer stands yep bed frame plus water pipe plus barbeque grill parts. Some stands even have swivel boat seats on them.

john in la · Jan 16, 2015

Welding it should not be a problem.

In some parts of the country old drill pipe is radioactive.

Under current law the oil companies are suppose to check the pipe before selling it for recycle; But I would still take a piece of the pipe to a scrap yard and let them check it with a Geiger counter.

Pete Hall · Jan 17, 2015

Ron
You are correct,my mistake
Sorry Old
I will try some 7014
Thanks for the info
