High speed camera video of welding electrode

Thought some of you might find this interesting. It's a video of 1/2 a second of mig wire stretched slow motion into 2 minutes. Enjoy?

Well... Listening to Yo Yo Ma was good.

 

That was educational, I've learned a lot.

 

Lol

 

That was a cool video.

 

Now you get out the grinder and grind off the metal caterpillar, can we see a nice flat TIG or Gas weld on sheetmetal as well? Bob

 

Was that a mig? Is that a magnified image of the wire itself or an arc weld (stick) electrode? No explainations offered, just a slo mo vid.

 

i think it's def a arc rod.

 

cool vid, thx

 

Not sure, I stumbled on the vid by accident

 

I'm alot more impressed by the technology behind the actual filming of the process.
Consider the arc-light created at 3500° ...

.

 

That looks more like a stick rod than a mig processes.

Now somebody needs to get that camera over to Brown Dog Welding's shop

 

Apparently, you people have never taken a close look at welding rods and mig wire.

Rods are coated, mig wire is not.

Still can't wrap you head around it? Look at the little round balls that are forming at the cold part of the welding process, they are cooled and sit on top of the cooler metal around the molten bead just like you find in every day mig welding.

In a word, fantastic.

 

cool..

 

Perhaps a comparison of bead size to electrode size would be a clue?
In the video, That certainly is not the cup or gas nozzle of a mig gun, that certainly isn't the tip of a mig gun and that certainly isn't the mig wire itself. Its slow motion not micro scopic.

The metal appears to be coming out of the center or barrel of the rod & going down to tge parent metal and as the coating leaves the rod it sits on top of the bead. Its clearly two different colors and two different paths of travel. Rod consumes and deposits from the center producing a hollow barrel.

The video is also titled welding electrode.

I've been looking at it for over 30 years.

 

Turn up the wire speed

 

Cool...


Some vids of MIG welding

 

No it's not MIG. I have slo mo videos of the various transfer methods you can do with MIG. Much more going on during a MIG weld. Unfortunatly it's all copyrighted and I'd get my tit in a wringer big time if I posted it.
Cool video none the less.

 

The electrode is being drug across the metal as opposed to being pushed. Therefore stick as opposed to mig.

 

Titled wrong, see the seam? I say flux core MigUpon second view I`m wrong no seam, electrode

 

Oh brother !
This is going to be one of those threads.

 

Are you saying you can't pull a mig weld?

Good videos Metal shapes. Similar to the I-CAR curriculum I use at school.

 

Nor push a stick rod

 

Humm....interesting. If that's the case all my curriculum is wrong. Not trying to argue just asking.

 

Arc welding electrode, melting from the inside of the coating.....
Seen it up close for over 35 years.........

weld on ............

 

You can push a stick or drag a mig if you want. Maybe after 40 years I've
been doing it wrong and never knew it.

 

Just asking. Might be metal thickness. My curriculum deals with thin materials. I push or pull depending on the application. Always have.(maybe I've been wrong all these years ) I teach primarily to the I-CAR certification test. As I tell my students " I don't care if you hang upside down from your tails to weld, as long as your welds pass visual and destructive test!" Might be different for other applications, but either way seems to work just fine for what I do.

 

I think the statement was more about the fact that an assumption was made. The operator in the video could be doing it "wrong". I've seen many many people drag MIG. I don't do it myself except ER70s6 on thin metal in the vertical position.

Personally, I think the coating resembles a stick of 7018 (or similar), and that's about the right angle to run it at. Even the spatter looks 7018 to me. Tough to be definitive without more to go on though.

 

I agree. Most of my welding was on structural steel usually with .045
wire or 5/32" 7018 stick. Only time we drug a mig would have been down hand.
Pushing a stick never works.
Like you say, whatever works is fine.

 

Thanks Second, that's what I was thinking. We use mostly .023 on material from 24 ga to 18. I push most all the time myself.
