Horizontal V-Groove MIG Welding

[@spelunkerd]

Bob has given a demonstration of excellent technique. With the voltage and wire speed exactly right, he didn't get into trouble with burn through and secondary key hole effects. The bead on the back of the weld was exactly uniform. In a way, it would be educational to see how he deals with real world problems -- Often you have only one chance to get it right, using an unfamiliar machine and nonuniform materials. Also, a demo of the same weld with stick would be useful. Thanks!

Thank you, I'm watching from BRAZIL, and this knowledge has tremendous value for me that I am studying to follow this fascinating profession!

Bob is a Master, best wishes to Germany from USA....Paul

[@xRaw381]

i agree, i work as a fabricator and quarry fitter and welder, and some peoples idea of welding is so 'college orientated' its unreal. theyl get a shock when there lying on a cold dirty floor in the winter welding overhead and getting showered with sparks

[@ericartis6960]

Comes with the environment when your getting paid.

[@trigger0403]

Well that's what leather jackets and balaclavas are for ....

[@DragonsAurora]

Floor. Do that in a rock drive out along road in 37 degree and rain. Lol the sparks are ok they help warm you up till you catch fire hahaha

[@DragonsAurora]

@@trigger0403 lol. That helps keep fire on you to burn longer

Very nice job guys! Thanks for the demonstration.

[@eliasrudnitsky3884]

how about gmaw spray arc transfer mode using hard wire doing a 2G horizontal for a bend test? using .045 or .052 Lincoln hard wire

[@socialistpete]

I've been searching for the same thing. In all these globular videos they run so slow.

[@eliasrudnitsky3884]

plus spray at pretty hot settings is a lot more difficult than globular, and id like to see the plate bent until it cracks so its not just a visual pass or visual test but a stress test

[@joedrums1987]

You can run the GMAW-Spray 2G test with backing and at spray arc settings depending on what gas mix you are using. The higher the CO2 content the higher the voltage will need to be. If you are using 90Ar10CO2 try 350-420 IPM and 27.5-28.5 Volts with .045 diameter wire. The Spray arc is hotter but is not difficult as long as you are not carrying too much weld metal. I always try and keep the 1/4" weld size through out my tests.

[@isiahgarcia1652]

Bob Moffat is badass

[@antonijebrkicvukelic8298]

Bob is a legend! We want his videos

[@michaelj6645]

Half bevel flux core welds. Need information on Heat settings, travel speed, push or drag. Plate has no backing strap but has a "strong back" on 3/4"-1"

[@raynellmoore68w]

I do more smaw and gtaw than anything but rule of thumb if you have slang you drag. Now going uphill il push slightly at about 10 -15 degrees

[@JaacoS1KRR]

Travel speed 4, amps 24.5, i prefer push on my hotpass drag on my caps

[@holdmybeer]

Great video. I would like to hear advise from Bob on vertical welds.

[@klee97516]

Bob reminds me of my mentor, very knowledgeable 👨‍🏭👍

[@ericartis6960]

If your welding the same material,are you suppose to use a backing plate if you was to use spray arc transfertechnique.If your using same voltage/wire speed?(This is a question.)

[@ypaulbrown]

this is open groove, a backer is not used in this test....spray arc is not used in the 2 G position, only 1F and 2F

[@davidhester8597]

I was taught to push mild sreel wire and pull flux.

[@youbetyababy]

Great! Thanks a bunch guys.

[@kaieteurcanada]

Amazing... that the top plate didnt tend to fold over inward with all the heat in the middle....?

[@jaymiller7986]

Thank you for the video. I have alot in common with you both. I have been in the industry for 33 years and still learing almost daily. We are currently working in introducing pulse spray stainless mig welding into our manufacturing process here. I am currently trying to qualify a process to pulse spray horizonal on 3/16" plate. A36 to 304ss with an open root. Anybody got any reccomendations here or links to videos ? thank you

You guys should show some videos of SMAW Fillet & V-Groove welds! :D

[@maintmech1245]

How about a 6010 root pass on pipe (any position)?

[@tater357]

Today I'm doing a 2g horrible using a .052 MetalCore with a 1/4" gap. Not sure if I'm ready but it's gonna happen

[@jeremiahbullfrog1844]

did it happen?

[@chadclark1344]

Please tell me your exact settings for dragging your stringer, and the gap size

[@devinf783]

I'm doing a 2g d1.1 type weld test for work. They want me to run around 245-260 amps for a 1" plate with a 45* bevel and a 1/4" backing plate. I'm using rapid arc with .45 70S6 and I'm having a hell of a time. I can't do more than 3 passes before things start melting away on me and rolling over. I try to give it a little time, but it's takes 9 passes minimum to fill this b***** up. After 4 passes my height somewhere along the groove is mismatched. At this point, I'd much rather do 3g.

[@Mr215Alive]

I wonder if this just looks good or does it actually pass a bend test?

[@rocketsauce420]

It’s it’s a bob Moffatt weld, It’s gonna pass a bend test.

[@ypaulbrown]

@@rocketsauce420 you got that right........Bob is the MAN...

[@hotsaucenchick3n]

what filter is on that camera during the welding, its like, BLUE. its amazing, any welding hood filters this color?? ITS AMAZING HELP

[@Welddotcom]

This is shot through a special camera filter, however there is a Blue Cobalt welding lens that gives a blueish effect similar to this.

[@hotsaucenchick3n]

i heard they stopped making those a long time ago. if not WHERE CAN I GET ONE I NEED ONE ASAP

[@glenny150976]

How come hes dragging it ive always been told to push when using bare wire ??

[@Welddotcom]

This is an open root. If you were pushing the wire it would just shoot into dead air space.

[@half_thai_guy4221]

couldn't he have pushed it with the same gun angle he was using, or would it be almost the same thing as dragging it? i think to, I've learned to push it instead.. i think im gonna try it this way though

[@Bodyperfection101]

If you push rather than pull you run the chance of the puddle running ahead of you. This can cause two problems, one lack of fusion and two possible cold lap at the very end, also your penetration will be far less with a push than a pull.

[@half_thai_guy4221]

thanks !

[@lamerariataaaaa]

What were the settings ?

[@turtlewax3585]

He did not clean the silicone deposits before doing the cap?

[@jeepncolo]

I am curious to know if he stayed at 230wf / 18volts for the fill and cap.

pretty much sure he did.....he would have said different if he did not...

[@armoredwelder6677]

Awesome!

[@KastigoKSJ]

I don't know, but, I found vertical up, spray transfer, to be more difficult than anything horizontal. Just saying.

[@ypaulbrown]

not a recommended way to weld, how id it come out, was it a fillet or groove weld

[@KastigoKSJ]

@@ypaulbrown seriously? My comment is from 9 years ago! Say, Paul, what did you have for breakfast nine years ago? Hope it wasn’t a pound of bacon and a dozen eggs because the surgeon general doesn’t recommend that. LOL. 🤣🤣🤣

[@tgkg]

Please do a recording on Flux Core 2G weld.

[@luisbonilla8306]

its about the same as welding 2g solid wire mig just hotter and a little more perpendicular to the plate just keep a tight arc and you should be fine

[@JujuiLuv]

why does miller run stringers instead of this ?

[@ypaulbrown]

what?

[@johnweslyjohnwesly443]

Thank you sir nice ...

[@glenny150976]

But he pushed it on every run ?

[@ypaulbrown]

put your glasses on, it is a drag weld, and even he did push it, it would be acceptable .....and just as strong, they have videos done later that compare the differance between drag and push with GMAW....check them out

[@joachimsingh2929]

Thank goodness for bob. Don't know what happened to the channel. Why is that kid on every video now?

[@JoshuaZiesmer]

yup, college welding and real world two different things. when your forced to weld out of position, or doing repair work while hangen upside down under a semi trailer trying to weld with an arm that's fallen asleep, you gain a unique perspective; suddenly all the welders that spend their entire carers with their ass on a cushion start sounding like your fifteen year old son in drivers ed telling you that your doing everything wrong, and your like, " was I that annoying when I was in school?"

[@An_Urban_monk]

josh ziesmer I'd venture to say bob moffat could kick your welding ass any day dude. Post a video and show us the exact same weld done by you. You can can let the world decide. College profs who write on a black/whiteboard all day are worlds apart from dudes who actually do the work as shown here. The proof is in the pudding not the trolling.

[@SpAcEjAmZ]

why is the plate at that angle? it's like the bevel of the bottome plate is already sitting flat

[@johnweslyjohnwesly443]

Edwin Yu ...bro that's horizontal position...

[@ypaulbrown]

3 reasons, 1, it is allowed in the specifications for D1:1 code AWS and 2, it makes filming easier and 3 for students learning, [it is in a college setting] it makes it easier to learn

[@carlosnunez2729]

This mig weld is in not horizontal, this is in minor angle to weld on horizontal what I that!!????

[@ypaulbrown]

you are mistaken Carlos, it is a 2G weld which is a horizontal open groove weld.....it is tilted about 10 to 15 degrees which is in the AWS specification for a 2G weld, D1:1 structural weld code....

[@siimtuulik6344]

Too cold welds, no preheating, not enaugh cut in, starts are weak as hell, and the end part is crooked as F cause didn't take the upcoming distortion/pulls into account when tack welding it in place.

+Ricky Ramirez check out overhead videos as well they have similar difficulties. I find it helps to say stay ahead of the puddle with MIG. I have to go slow with stick but get moving with MIG.
