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!
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
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
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"
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
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.
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.
@@dudemanbro2714 yes, that is right, I am the fun police, does Dante Crudo mean the Devils Dirt? have a little respect for others, in case you did not know, Mr Tig, Wyatt Swaim was killed last week in a vehicle accident....save your negative comments for the ones you hang out with, not the ones who are sharing information for the betterment of others,
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.)
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
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.
Main India se hoon or 10 year experience in welding field i do mig, tig , spot , gas welding i want to do job in foreign countries like automobile if any recruitment please inform me thanks all
@@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. 🤣🤣🤣
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
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?"
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.
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.
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....
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
+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.

Comes with the environment when your getting paid.
Well that's what leather jackets and balaclavas are for ....
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
@@trigger0403 lol. That helps keep fire on you to burn longer
Lol
Regards from good old germany. I saw 1 of the best welding-videos ever. Thank you so much for publishing !
Bob is a Master, best wishes to Germany from USA....Paul
Very nice job guys! Thanks for the demonstration.
Bob reminds me of my mentor, very knowledgeable 👨🏭👍
Bob is a legend! We want his videos
Bob Moffat is badass
Great video. I would like to hear advise from Bob on vertical welds.

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"
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
Travel speed 4, amps 24.5, i prefer push on my hotpass drag on my caps
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
I've been searching for the same thing. In all these globular videos they run so slow.
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

Great! Thanks a bunch guys.
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
did it happen?

You guys should show some videos of SMAW Fillet & V-Groove welds! :D
Amazing... that the top plate didnt tend to fold over inward with all the heat in the middle....?
“Bob before you continue, stfu.” “Hi, I’m Mr tig and it’s all about me but today, I’m required to let this peasant show you how to mig weld.”

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
Great and helpful for us lefties!!
I know that's right, kinda messes with the rights......cheers, Paul
Thank goodness for bob. Don't know what happened to the channel. Why is that kid on every video now?
I wonder if this just looks good or does it actually pass a bend test?
It’s it’s a bob Moffatt weld, It’s gonna pass a bend test.
@@rocketsauce420 you got that right........Bob is the MAN...
Awesome!
Please tell me your exact settings for dragging your stringer, and the gap size
How about a 6010 root pass on pipe (any position)?
Thank you sir nice ...
Please also to record a video in FCAW process in position 2(horizontal v-groove),
it just has slag clean it
what filter is on that camera during the welding, its like, BLUE. its amazing, any welding hood filters this color?? ITS AMAZING HELP
This is shot through a special camera filter, however there is a Blue Cobalt welding lens that gives a blueish effect similar to this.
i heard they stopped making those a long time ago. if not WHERE CAN I GET ONE I NEED ONE ASAP
Michael Conigliaro I heard they stopped making them as well.
@@hotsaucenchick3n the lincoln 3350 is blue filtered.
does anyone know what settings he was using
He did not clean the silicone deposits before doing the cap?
How come hes dragging it ive always been told to push when using bare wire ??
This is an open root. If you were pushing the wire it would just shoot into dead air space.
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
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.
thanks !
What were the settings ?
Please do a recording on Flux Core 2G weld.
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
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...
Main India se hoon or 10 year experience in welding field i do mig, tig , spot , gas welding i want to do job in foreign countries like automobile if any recruitment please inform me thanks all
I don't know, but, I found vertical up, spray transfer, to be more difficult than anything horizontal. Just saying.
not a recommended way to weld, how id it come out, was it a fillet or groove weld
@@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. 🤣🤣🤣

if you are a welder and this is your least favorite weld. then you have an EXTREMELY EASY WELDING CAREER.
That weld is a1,
But he pushed it on every run ?

why does miller run stringers instead of this ?
what?

Watching 2024
This mig weld is in not horizontal, this is in minor angle to weld on horizontal what I that!!????
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....
why is the plate at that angle? it's like the bevel of the bottome plate is already sitting flat
Edwin Yu ...bro that's horizontal position...
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
I prefer pushing technic rather than drugging
mehmet balta right and it's easier to see where your puddle is
how much open grove D1:1 do you weld pushing?
Mig welder, not 7018 😅😅
what are you talking about.....yes, it is MIG or GMAW or MAG....who ever said anything about SMAW 7018
@@ypaulbrown dude been breathing in too much of them welding fumes 🤣
That old man he doesn't know anything 😀😀
sounds more like you are the one who knows nothing.....
수직으로 세워. 해야지요. 현장에 서 수직이 많아서
He could've just used the wire wheels lol
I think the reason for using the grinding wheel was to smooth the bead out for the hot pass......not to remove the silicon islands
This one actually is not that hard to do.
This weld is kicking my butt, some people just have a natural ability to pass this with no problem, this video will help me a lot :)
