Pipe fence problems with cracks happening

[@paulmeersa7162]

You have high Carbon Cr Mo V drill string pipe there cobber, then you have a 6010 hydrogen rich filler rod. Now you have the classic case of H2 delayed cracking, to a tee. This fault is nothing to do with magnetism it is everything to do with a high carbon equivalent and hydrogen. Preheat 95 Deg C and use a properly preconditioned E7018, clean the INSIDE of the pipe too. Wait two days for it to crack. If it doesn't you are good to go for loading it with beefies.

[@mattbuck8087]

Yep he's using wrong rods this shit ain't ment to be welded in the first place 6011 on pipe fence completion production pipe nothing else

[@gusferguson8353]

That's drill rod isn't it? It's work hardened and magnetized. You need to get it blazing hot, let it cool a bit, and weld it while it is still pretty hot. And use 7018.

[@godwinwelding7172]

Thanks I have had to do that ina different situation before

[@mperry2384]

What? Bro travel speed was too fast. A few beads were seated in there with only hopes and wishes touching the parent metal. Fit up was bad or u tacked all horizontals and by the time u got to the top it spread that bad. Next time there's a loud pop when welding grab a square and poke around for a few

[@mperry2384]

Cracks cleaner than mine. Lol gap was to big and arc force was focused on the vertical post. Gotta weave when gaps bigger than rod....

[@bjen2005]

@godwinwelding7172 - I saw something like that year ago, not in a fence, but a piece of flat steel. Engineer told me it was something to do with the magnetic signal properties in metal . Didn't really understand all that he was talking about but, I would say you are spot on talking about the pipe being magnetized and causing the crack. I wonder if welding on the AC side would make a difference if you switched to 6011 instead of 6010?

[@godwinwelding7172]

That’s interesting 🤔 I’m gonna have to give it a try. Thanks

@@godwinwelding7172 Couple of ways to deal with magnetized pipe. 1 - Smack it with your BFH to knock the magnetization out of it prior to the arc. 2 - 5 opposing wraps of the leads on either side of the weld

Switch to lo-hy (7018). Either cold cracking or brittle material, or both. Peen your welds. Read up on lamellar cracking in the HAZ.

[@deerussell7088]

Metal expands in heat and subtract in cold weather drill holes in the bottom of the pipe to relieve the pressure.

[@zombieresponder]

I'm a machinist with heat treat experience that also welds. I would say that particular pipe is probably high carbon and other alloying elements. Your weld heated the steel enough to harden it, and then when it cooled and contracted the stress was enough to start a crack in the heat affected zone. Grind a v in the crack, heat it with a torch, weld it, then heat again with the torch. Check the hot zone with a magnet. Once it's no longer magnetic, critical temp has been achieved and it should be slow cooled to prevent it from hardening again. Personally, I'd probably wrap it with a welding blanket to keep it from cooling too quickly. If the ambient temperature is above 80F or so, and there's no wind, you can probably get by without that.

[@godwinwelding7172]

That’s exactly what we did to fix it!

[@koreywhitt9484]

If it really cold outside it can do that. Never happened to me, but I’ve heard of it happening on the pipeline.

[@JH25780]

I’ve see it happen a couple of times. I’ve had luck welding it with 7018 and it not cracking but I also had one that would split the pipe after a 7018 weld. It’s a gamble with used pipe.

[@godwinwelding7172]

Yes I have learned it does what it wants to. Thanks for watching

[@samevans4525]

It looks like it’s acting like cast iron does and pulling too much carbon into the heat affected zone, maybe a good preheat ??

[@sashagertzina5558]

в этом металле много углерода . нужен предварительный нагрев

[@arthurborrego4738]

Thats why i use 6011 on ac mostly on pipe fence .... sometimes you cant tell theres magnetism and 6010 dc or 7018 will lay on it just fine uphill running hot but it will crack sometimes ... could be a bunch of things .... on gates and such i do 6011 ac then 7018 usually heating it up with the first pass will get rid of the magnetism enough to lay some 7018

[@chadkennedy529]

It's induction hardened pipe it does that. You need to get it slightly red let it cool weld and post heat it slowly.

[@godwinwelding7172]

Thanks for the info. We will have to try that next time!

[@stoneroastery]

Heat the pipe 1st then weld it. 7018 rod use a temp stick try 250f

[@derekbryant6137]

Magnetized plate and pipe will do that best way around that is an AC stick welder but not too many people use those anymore

[@darulalquran2960]

I remember when I was in the academy , the cheif use to put some of the pieces that he hd just welded in the oil directly after welding , he said the reason why cause this type of metal , is combined with other elements , it shrinks by the high heat , then it expands after the piece cool down , thats why it crack need to stay in hot temperature till it cool down slowly to not crack , thats why he put the peice welded in oil cause it guard the temperature ,

[@darthwelder652]

I believe its a combination a few of the conditions mentioned in prior coments. Also how long is the fence, too much cooling/ contraction would add another condition to failure. There is a coment in here about high carbon content from comination of the pipe alloy an electrode type. High carbon to me in simple terms means brittle material. But the distance between the crack and weld points to brittleness in my opinoin. Weld on yall. My the weld hold you

[@Hjfvvdst]

Stress Crack. Right at the edge of the heat effected zone. It appears like the horizontal pipe was much cooler than the vertical pipe. The horizontal pipe sucked the heat away too fast, and that is why it cracked. The way I have seen this done that I think is better is weld a stub on the vertical pipe slip the horizontal pipe on it leaving about 2 inches of slip. When the heat is up or down it allows the horizontal growth to not effect the vertical posts.

[@rodmzn007]

You need to warp your ground around the pipe a bunch of times to get rid of the magnetic charge in the pipe .

[@michaelschulz4317]

Were you using new rods or old ones? 7018 with moisture in it possibly? Ive welded lots of pipe but ive always used t-11 wire but 6011 with really rough pipe.

[@CarlosMorales-jd5hb]

6013 and an AC buzz box

[@channelview8854]

Magnetism has nothing to do with this. It only causes arc blow during welding. You have gotten hold of some very highly alloyed pipe and the heat of welding plus hydrogen in the rod has made the heat affected zone hard and brittle. You are gonna have to pre and post-heat and use a low hydrogen rod, properly conditioned in a rod oven. I have successfully welded a leaf spring on a farm trailer by pre and post heating and using that MG600 rod. It's deathly expensive but it can get you out of a jam.

Magnetism. We run into it once in awhile. Usually happens more when it starts getting colder at night and hotter in the day, towards fall time of the year. But magnetism is your culprit. A chain can fix it. There’s a couple other ways too.

[@godwinwelding7172]

Yeah we have tried all kinds of old school myths with not much luck on magnetic pipe. I’ve just never seen it crack that far away from a weld before. Crazy stuff.

[@FLYWHEELPRIME]

Everybody in here telling you pre and post heat is correct, but you don't need blankets and all that fancy garbage. Just anneal it with a torch (assuming you run one) and weld that bastard hotter than normal. You'll be good if you get at least 3 inches annealed wherever your connection is

[@wildnfree223]

You know to properly anneal you must slow cool it right ? ...... heat above upper critical (loses magnetism) and slow cool

I think its the material you using I was kinda thinking maybe that could be 1 1/4 chrom or higher I don’t think it’s from being magnetized Though it will weld kinda wild, not wanting to tie in right and may leave porosity if it’s magnetized I think that material is not one hundred percent carbon steel You see chromo gotta be preheated and cooled slow by wrapping in with K-wool or some sort Or it will crack most definitely
