MIG Welding 3g Vertical Open Root Plate Test

for a detailed article on this topic go to goo.gl/abO4Pi
visit the store here weldmongerstore...
this Mig welding test is used mostly as a preparation for pipe welding. The settings that you get dialed in for plate will also translate just fine over to pipe welding. Downhill root and uphill fill and cap is pretty common for pipe shops.

That looked awesome. Your definitely an inspiration to us younger generation welder. Every video you post has helped me in my welding career. I am working for Huntington Ingalls shipyard and everyday I try my best to become better and a Master of my craft. I just want to thank you on behalf of all the younger welders that have been truly inspired by your work and techniques. Thank you!

[@nightelf4161]

in welding school and that is the most beautiful weld ive seen yet

[@kalebmoore7290]

an alternative to a root with more penetration using a tighter gap like that would be to crank the voltage up to 18-19 volts & turn down your wire speed! like 18.5/180-190. was tricky learning that the longer i can keep the puddle molten, the more wire i can feed into it before it sets. when i started i just tried to turn it down & throw as much wire in there as i could do long as the machine ran well & what you start to realize is the roots sets faster the colder you go & the increased wire speed only fills the gap faster so it doesn’t necessarily give you time to break down the walls & let the puddle soak up any wire.

Welds look good. Some diffrences in what you are showing and what I was taught in the boilermakers apprenticeship no down hill all verts and that also includes root pass. Most of the time we are allowed a backing plate but sometimes they want it to be an open joint. Caps are done in 3 passes. One in the center and then one on each side.

In my school we are certifying with 4x7x3/8 plate in the horizontal position with a bevel (one flat, one prepared) with a 33 degree angle can you possibly make a video for that it'll be very helpful

[@JellyGrease]

I think its way better if u do the root uphill. Not only u can control much better the puddle and the wire at the tip of it, but u get a waaaay better penetration behind. Just my way to do it. And if possible, ill use solid wire for the penetration and flux for the filling! Nice welds!!

[@senuolicak7097]

why you need to go uphill and get penetration since it's an OPEN root ?? isn't more difficult to do so ?? may be uphill just for fill & cap ?

Hi Jody; Going back to your Stick Welding Tips Vertical 7018, you said some testers were not allowing weaving because of too much heat input causing grain growth failure, how does it or will it apply to the weave when doing a mig vert. up, like in this video. It seems to have similar heat input to the work and if it causes a problem with stick welding, why wouldn't it cause a problem in mig welding also?Thanks again for your videos, your channel is great.

[@guitarsinatra4718]

I know that welding vertical up is not the only way to do it, but why did you chose to do it down? What is the difference between up and down? Does up have more penetration? I am on a welding school and about to certify and need to know as much as I can! I enjoy all your vids thanks !!!!!

Jody, I'm getting ready to weld up side strips that go around the perimeter of a table top. It's aluminum, and I'm not sure how to approach this thing in terms of avoiding distortion. I want the table to be flat when I'm done, but will be welding this strip all the way around the perimeter. It may not be a problem, but it sounds like a recipe for distortion. I've got ideas as to how to keep distortion down, but I'm curious if you have any general ideas on how to approach this thing. I watched your video on distortion, but don't know how that would apply to what I'm doing. After all of these years I have to thank you for the zillions of excellent videos you've made.

[@4spida2fingaz0]

I also noticed at the very top of the plate that it gets almost too hot and the puddle recedes and draws the plate metal creating a divit per se at the very top. This is a problem I've had welding plate GMAW or smaw in the past. how can you prevent this while having well enough amperage to get good penetration but without causing that? Maybe sacrifice a solid bead for a tie in mid section hit it colder on the final segment? What do you say?

Idk how to figure out this problem hope it's not a bad machine can anyone help thanks.

[@Tyykjen]

where i work i got told that we should never weld downhill. I weld the rootpass on 6g and 3g uphill. is that wrong?

[@iw63boomer]

Not at all. A lot depends on the thickness of material, process, gas mix (if applicable), and ultimately, what does the WPS say. Up hill is a structural weld. Manufacturing uses a lot of down hand, some kind of wire feed process; usually with a spray transfer which allows the welder to use higher voltage and wire speed. Learn both, but if you have the uphill in control, the down hand should come to you without too much effort. But put some practice in on down hand, in case you run across a WPS that calls for it.

[@senuolicak7097]

is this even possible ?!!! I was searching for videos doing uphill mig on rootpass but it's sooooo rare ! why is that ?? I heard that downhill is avoided because the lack of fusion and inproper penetration, but since it's an OPEN root I can't see why ??, without mentioning that you increase the risk of shooting the wire through and thus you loose the arc, I think it's more difficult.

[@lenjohnson4574]

great video Jody. I do have 3 questions for you tho. on a plate test like that, is going down-hill acceptable only in open root? in school they only allowed us to go uphill on the 3G plate test, but that's with a backing plate, not open root. can up-hill be done 3G open root? and grinding... when you want to grind a weld for aesthetics or looks what's the rule or proper way of doing that? I have ground down some welds for looks before, but only ended up weakening the weld and having it break loose or fail. thanks in advance

[@joseibarra-oo7wd]

Looks great have a question I have to do vertical on 3/16 plate form my job cant get my weld to look good its not the best looking ones haven't had them break on me but can you do a video on thinned plats than you

[@joopterwijn]

I "learn" welding the hard way; just do it. It was not included in my school training (other direction) :-) I wonder if you could do a video (serie) on mig for rookies. For instance my machine does not have a gideline chart on wire speed and current with material thickness. So I just try and if I do not burn trough I think I should be ok. When do I use a bevel, or when not! What does a sputter mean, more wire speed? More gas less gas... I enjoy watching your video and am great full to you for putting them online, THANKS!

Why don't you use a slight drag angle on your uphill passes? It should carry a hotter puddle and increase penetration.

I did this one vetical up on an open root and also the over head open root on a two pass...

[@DubYOUUP]

So why downhill for the root pass is that just the best way to do it? what would happen if you would to do a uphill travel for the root? another thing for the second pass I notice your doing a z weave motion and it came out extremely good my settings must be wrong when I try doing an uphill travel with a z weave motion I get a lot of buildup and ends up dripping how do I counter this? try going a little faster? maybe change my voltage or wire speed? cheers & great video

[@juwancummings6945]

Increase wire feed speed.

[@gizmo75000]

Go faster, spend just enough time in the middle to keep the puddle moving, spend the majority of the time on the toes. Hardwire mig doesn't like to do uphill without drooping, with practice it will become smooth. This was the first weld I ever did with mig, most of my experience was with stick at the time, took me 2 weeks to get it perfect

try a down hand root on a full pen inspected weld in california and youll be shown the door if you ovwerheat any part of the material "heat effected zone"youll fail the piece will failand if any of those passes are wider than 3/8 youll fail and who uses hard wire on a weld test 71m 71t dual shield with straight co2 is all you need which produces a slag but there is no easier wire than dual shield 0.52/.0.64,even after you get your certs in our shop you will take another when you apply and if you run a cover pass as wide as that youll not make it in Cali 3/8 is as wide as they let you go ive welded 1"plate tro w36x120 with a full pen with open root 1/8 and a single 30 deg bevel with and without ceramic backing bars,they can eliminate the need to carbon arc the backside and your talkingf a 1"weld and that was at least 15 passes

[@johnt9810]

Hey, I finally got consistent running my MIG root up hill. I had problems with either lack of penetration or blowing out. Played with all kinds and combinations of gap and landing dimensions. Here's what worked for me: 1/8" landing with 1/8 gap. 18.5 volt and .035 wire set on 3 of 10 on our Miller wire feeder (sorry, no Ipm) For me the 1/8" landing was the big break through. Tried a 3/32" but I had problems with the gap shrinking closed on me so I went to a 1/8". I feather in my tacks to help with tying into them but I don't grind them so much as to weaken them. I use a "Z" pattern going from the corner formed by the landing and the bevel on one side to the opposing corner letting the puddle tell me when to move. Gun is at a 15° push angle. If/as I see the gap shrinking closed I tighten my weave and try to make sure my puddle is flowing into the gap. "It's what worked for me"
