Is MIG Welding Downhill As Strong As Uphill?

[@JamesPuckett-t6i]

Uphill or downhill, either works great. In 34 years of mig welding in a pipe fabrication shop, never had a problem running downhill on roots.

[@AustinHargett]

1000 percent

[@artv787]

@JamesPuckett-t6i Same here 37 years of Tig and mig fabrication. I've had no problems with downhill mig welding

[@beams_garage]

Great video, I just spent 16 weeks at local MIG school and cert'd on spray transfer. Nice to see the results on short circuit up and down hill. Always learning....good stuff!

[@Backfire10]

As a non-professional welder, this is a really good explanation of up hill and down hill. Hope you both are coming to Fab-Tech. Great job gentlemen.

[@AustinHargett]

We both will!

[@blueweld75]

Pretty dope my dude. I had to see it to believe it. And its wild to me. Open Roots all day can be done with short circuit mig . But its wild to me, seeing thicker plate not have lack of fusion in the side wall. I know folks have procedures out there in the wild . But its just so hard for folks to get GMAW-S to weld repeatedly over and over and over with out failures in thicker bits , after an open root. Very rad my dudes, I have failed a lot GMAW-S welds that where in thick plate . It was super rad to see one passed. Now I am going to have to go try one after this outage I am working .

We're currently welding a project in pairs and my partner is a much more senior welder. There is a part of it we need to weld where we can choose whether we go uphill or downhill. I weld downhill, but my partner welds uphill and keeps insisting that I should too. He had his uphill weld fail twice on the UT (in the year since we're working together), while mine hasn't failed even once, but the stubborn old goat just keep nagging me about it. Sometimes, if the sheet allows it, you just go for whatever's easier for you, and if its good enough to pass inspection, don't let anyone talk back at you about how you're going about it!

Thanks. Great content and the proof was in the pudding! Just as good when done correctly👍🇬🇧

Thanks for watching!

[@atomichydrogenweld2823]

great video guys,,,,,,loved seeing those bends....

[@ypaulbrown]

Austin, you never mention wire diameter , at least up to 7:38.....We think that may be helpful for your viewers..... otherwise, great information here......hope to see you at Fabtech......cheers from Orlando, Paul 'Paulie' Brown

[@philmurray1359]

I was surprised at the low voltage. Good to know, i will definitely try that.

[@peetky8645]

what size wire were those settings for? 035, 045?

[@darrellolsen1204]

Great video 😎👍

[@jray1298]

Man I work in a production shop we run mig and flux in everything from 2 1/2 inch all the way up until 14 inch and then we do mig and sub arc all down hill beads and pass cray everytime

[@ReBeksonn]

Both are good,but downhill is harder to master. Cold weld is a real problem with downhill

[@blackwaterrepair10]

@@ReBeksonn it's quicker and easier imo when you getbthe hang of it

[@MCPr0m0]

I would say downhill is easier, you aren't working against gravity.

[@JamesPuckett-t6i]

@@ReBeksonn the great thing about gravity is, it can work for you, the bad thing is, it can work against you

[@peetky8645]

Do you have an idea of what wire size they would be using for an 18V open root MIG weld? They left that out of the presentation and it is kind of an important piece of information. 18V and 180 ipm seems like what i would weld 16 gauge tube butt joints with 030 wire?

[@phillip-cl8bk]

great video! great work!

[@rudyrivera7426]

Thanks for sharing! 👌👍

[@atomichydrogenweld2823]

9:43 he mentions bumping up the heat a little bit by raising the voltage from 18.5 to 19 volts, and then bumping up the wire to match the voltage, I thought amps were the heat input in welding, like stick or tig, and the voltage was the force behind the arc to jump the gap ? does mig not consider amps to be the heat ? or am I missing something......thanks in advance, Robert

[@dotark]

no with mig and flux your amps is same as wire speed

[@atomichydrogenweld2823]

@@dotark the amps are not the same as wire speed, due to the different thickness of wires.....only .045 wire is a direct translation, 100 ipm equals 100 amps.... .045 at 100 ipm divided by 1 = 100 amps .023 ipm is divided by 3.5, .030 ipm is divided by 2 .035 ipm is divided by 1.6 [160 ipm = 100 amps]

[@dotark]

@atomichydrogenweld2823 thank you for the fix my comment was poorly worded and I kept it to simple. What I should have said was wire speed correlates with amps. More amps more wire ( and a colder weld because to much filler to fast. Not the best way to cool a weld but it can) this is why even on the name brands like Miller and Lincoln you will see some wire feeders use wps for wire speed and some are labeled as amps

[@peetky8645]

@@dotark you were correct in general. increasing WFS will increase the amps and heat of any weld while decreasing will do the opposite.

[@RIPSlawd]

Only matters on structural welds, you’ll never be given a WPS with downhill on anything structural. If you can’t uphill something, get some more hood time until you can

[@furstngomambi]

New to Mig welding informative video,i just bought a Mig welder it only has voltage and Amperage knob how do i know my wire speed?

[@LibertyDankmeme]

just a guess but it's probably voltage and wire speed - you shouldn't have an amperage setting

[@furstngomambi]

​@@LibertyDankmeme thank you

[@peetky8645]

I assume amperage is your wire feed speed(WFS). You can test this by holding the gun in the air and pulling the trigger for a 6 second count, measure the wire length with a ruler and multiply by 10 will be your wire/minute speed.... then change the amp knob and re measure.

[@SouthernGround]

Depends on thickness, as long as you get adequate....... yea.

[@robinsonsmotorcycleandauto3929]

Now bend the roots without any other welding done.

[@MrRNTV]

It’s nice to see a professional sweat alil bit on a bend test. Lol

[@blkcoupequattro]

Uphill makes some sense visually, but minimal difference if any in strength of the weld.

[@AustinHargett]

Same wire and same basement, same strength.

[@YR7A]

I feel like this channel has gotten a long way away from where it was when Bob was doing the presentations. It felt organic, simplistic, and got the point across without any filler. The videos now all feel so flashy and fast paced with all of the jump cuts and edits.

[@LibertyDankmeme]

the beard mic tho lol

[@ChiefChizzy]

Don't even wave to watch, the answer is no, but yes.

[@SleepyChihuahua-ip4kn]

When it comes to mig or tig it doesn’t matter if you’re going up or downhill, there’s no flux to get in the way and that molten metal don’t care if it’s going up or down

[@AustinHargett]

Biggest issue is carrying to much metal. As long as you watch it. Like you say, all is fine

[@peetky8645]

@@AustinHargett do you have any idea what wire diameter they were using for the 18V root?

Learned to never weld downhill bc it wont hold
