7018 Open Root Challenge

#welddotcom
It's his first first time welding 7018 open root.
No research.
No advice.
Just a little prayer to the welding gods...

You also get serious porosity when long arc a 7018. Thanks for the promotion! Love your videos even more right now.

Some welder talked smack to an engineer and next thing ya know there was a blueprint with a 7018 open root pass

[tartssavage]

This is what we are taught to weld with here in scandinavia, 7018 all the way.
We almost always use remote controls in one hand while welding root and the basic tehnique for both pipe and plate is to repeat a U movement with the electrode within the groove and letting the root fill up. Awesome work guys!

First thing in the search engine after typing in “7018 stick welding open root” was literally Bob on Weld.com’s youtube

I welded pipe in Sweden back in the 90s. Swedish welders and most Europeans use a hand remote to control their amperage while running the root, filler and cap. If the root is done right, it will peel off just like a 7018 cap. The root should be 1/8” gap run on negative, using a diamond motion. Since, I’ve moved back to the West Coast 28 years ago, I have never seen a 7018 root in America. It kicks ass. Cheers TyT

[davidcraft]

finally someone who welds like me lol.

[jojorumbles]

We do this all the time with 7018's on the shipyard. It's always assumed back gouging will be necessary to get the slag and porosity out.

Hey Mancub, in welding school this week we learned to do this, you want to weave back and forth in a tight arc, with a 1/8th rod I was doing 85 amps cold, keep your stick at around a 100 degree angle and keep your wrist in the same position, trust me it worked really well for me.

[jonmiddleton]

7018 u need a tight arc. Stops porosity. 2.4 mm gap and land. Can hold it in at about 80-90 amps, DC Negative 😀👍🏻

[hiramwillis]

Awesome to see people be honest and teach about what they learned instead of just making it seem they are the Betty Whites of the industry. Love the videos and I recommend them often.

So at least from a pipe fitters perspective, we tack and do all open roots with 6010 not only because of its ability to weld rust, oil etc, but because it’s a fast freeze electrode. An open root with a 7018, being a fill-freeze rod would be very complicated because you’ll heat up and just start dumping metal out of the gap. The keyhole won’t be a keyhole because gravity takes over, and 7018s need more amperage, which means more heat. The instinct to whip out of the puddle is the biggest thing you’d want to avoid because you’re just whipping in all that flux, causing porosity. 7018s have to be steadily pushed, with electrode at leading edge of a steadily supplied puddle. There are probably people with more technical answers but that should be close.

I've done a lot of this welding. Set up that work for me : bevel edge 30-35 degrees, 1-1.5 mm landing, 3.5 mm gap, electrod 2.4 mm DCEP.

[davidthewelderman]

I learned to do this in my classes 30 years ago.... 7018 up hand cap heat, straight polarity, tight arc(pretty much walking the flux) and a straight in to a pulling angle to help smooth the backside. If you do it right when you buff the back you would almost say it was a tig root. Good luck

It's Justin Bartha from National Treasure.
This was too funny! 4:28 "and i'm pushing as hard as i can, it's not going in...oh, oh my god we got.... oh it's too big" 😂
the fact you guys video and post everything. Good to see you using the plate stand you made too.

[roybello]

I've done this but you have to reverse polarity to have a good penetration. I have to use 7018 as root pass bec. No available 6010 on-board for a time constraints projects.

[farmalltomf]

Mike, keeping it real is great. This shows how to work through and learn new techniques. Uncle Bob and Redbeard would be proud! Nice vid.

[quickshot]

Hey Mancub my welding teacher taught us how to do this these past few days, keep a tight arc and weave back and forth and keep your stick at about a 100 degree angle, you will be fine after some practice.

[venezuelanfest]

Look for Brazil welder, I think you need to keep it straight up, watch out for that key hole, Is a VERY difficult but not impossible

[Wild_Bill]

This is why I follow this channel shows me what to do and what not to do either way you learn

[dustinwolfe]

Props for posting the video despite the results
