@Wroger Wroger Don't think so. Just changing the gun angle will affect both the penetration and bead profile. I bet there will be some interesting differences between these wires.
@Patrik Einarsson Disagree. Process will change the bend characteristics. Spray transfer, the wire is sprayed into the melting weldment. The wire never touches the metal. Also gas changes will affect properties of the weld when you bend it to failure.
@@alienpoker So what's your point here? Would it be a bad thing to perform penetration and bend tests while comparing these wires? At least in my shop the structural properties of the weld is of great interest as well as getting the most bang for the buck. Also you don't need to school people who watch this particular video on how the processes work. I bet most of us are here because we have a professional interest in welding.
@S14kabuild Yes. This is exactly why some further testing would be cool. Also in my experience gas shielded flux core equals deeper penetration. So, there must be more to this than just different deposition rates by weight. However interesting that is in it's own regard.
After studying the history of welding in America it good to aee flux core is still holding it,s own. I keep 1 machine loaded up with fluxcore. Great vid Men.
I used to work at a shop on second shift when I was going to trade School. We ran 060 flux core wire. 30 volts and 275 on wire speed. This was required. It made great welds just like the ones you just tested. Thanks for the educational videos.
Our shop is right in the middle of moving from flux core to pulse metal core. A large percentage of what we do is out of position but if you learn to pulse that stuff vertical up you're golden. Thanks for a great video, very informative.
Wish there was a way to like a video more than one time, what an absolute gem; so full of information and well thought out production. The knowledge level and articulated way of putting it into words that almost everyone can understand makes it even better to enjoy, no personal preferences or BS beating around the bush just cold hard facts backed by solid data, thanks a lot guys.
Thank you for sharing. Very satisfying to hear the chiselling and see the melting process of the welding. That is the sight, sound, setting, angle I am trying to embedded or etch in my want to be welder of mine. cheers!
electrode efficiency for solid wire on spray transfer is incorrect: 10.5/10.7= 98.1% efficiency. For metal-cored wire, deposition rate cannot be higher than the melt-off rate. Assuming these got mixed up, then 10.62/10.92= 97.3%.
Wow now that was an awesome video you guys!!! The numbers really tell it. But it’s so cool to be able to do a comparison that way. I kind of suspected some of this with the tests that I’ve done. Of course they were nowhere near this detail though! Thanks
That was a really neat video, a lot of time and effort was put into setting everything up and recording data, and you guys did a really good job with it, Kudos
To make the test complete you should cut/polish/ets the samples and look at penetration, many a bend test. But overall a super interesting video! Well done guys keep them coming!
I’m on FCAW-G right now. I just passed t-joints yesterday so today when I go in I’ll start on my plates. At my school we use a 22.5 bevel on both with a ¼” gap. What I’ve realized is that you can’t be afraid to experiment with the settings a bit to figure out what settings fit best for me. Just turning up my wire speed 10 and I went from having spatter everywhere to not having everywhere.
Gotta admit you guys are BY FAR the best welding channel on youtube...keep up the great vids! :D Learning TIG atm but its been too long since iv'e done MIG....might give flux core a go or just mig anyway with the argon i have already :P
The shop I work at we use almost only Hobart metal core. We weld a lot of 1" thick up to 6" a514 at 29.5v and 350 wfs with .045 wire and 90/10 gas. I would say we get an almost excessive amount of spatter.
That makes sense because they're getting that wire to spray at 25.5v in the video, that extra 4v is just turning wire into spatter. Try turning the voltage down and bumping up that wire speed.
Shouldn’t the relationship of the deposition rate to the melt off rate coincide with the electrode efficiency? I’m coming up with 98.1%, am I missing something?
We tested metal core SMAW at work. A code shop. Running the wire wide open I could not get over 720 amps with 1/8 inch wire. The deposition efficiency and rate is crazy. Still think the solid wire looks better.
I'm behind the times! Although I have heard the term metal core wire, I just figured it was a fancy way of saying solid wire. Thanks for the video because I did a little research to find it's a very interesting product. Something that I probably won't ever run through my 40-year-old miller wire feed though.
Why do you limit solid wire to 5/16” and less(just curious)? I work in a machine shop and weld 1/2” and 5/8” plate all the time with ER70s-6 I normally run around 33/34 volts and around 600 IPM (my machine uses number dials for WFS :( ) and my amperage dial normally shows around 320 amps give or take with a short stick out. I’ve cut and etched scrap plates of this thickness before when I’ve had some down time to see if i need to adjust my settings. Needless to say i was fairly satisfied with the results, root and fills all looked good, so did my fillets.
⁵/¹⁶ is the filet weld size maximum for single pass. Not the material thickness. If you try welding a ⅜ single pass filet it doesn't penetrate as well because of how slow you have travel
Yeah, majority of the Flux Cored wire small shop or hobbyists use is gas-less. Dual shielded is what larger job shops will use. You have to get a specific Flux cored wire to do it that way.
I don't know what they did there. According to their numbers, they deposited 0.162 lbs of weld, using 0.278 lbs of wire. Doesn't add up, that'd be 58% efficiency...
Great info, thanks. Just one question: Why do you never (rarely?) ever use or mention gasless flux cored? Perhaps you could do a video explaining why you don't use it in a professional environment. As a retiree (AKA hobbyist) I find gasless to have a number of advantages for the small amount of welding I do these days.
Amazing and educational video. I suggest two improvements for future videos: 1- Use international units too ( you got worldwide audience strugling with unit online converters). The AWS recomends use it in the Welding Handbook and is a common scientific practice. 2- Cut, polish and Nital etch a cross section, to compare penetration.
This is an AWESOME test! What did you do with the wire in the whip? Didnt see that on the scale? Now that you have the samples, I'd love to see part 2, bend test/ penetration differences.
Absolutely invaluable information here, thank you guys for it. If it's not too much to ask would you be able to cut and etch them to show weld nuggets?
Very informal, I just got a Lincoln 140 HD from Home Depot And will be doing around the house jobs for myself. I was a combination welder in the industry in Houston Texas for right at 20 years. Most of my welding was heliarc and stick welding and very little MIG welding. I'm kind of leaning towards the MIG welding part of my wire feeder because I feel like it has a much cleaner weld verse flux core. I didn't know that there was a difference between MIG welding and flux core welding just that the flux core had flux on it. And Mig you can use C25 from what I'm told. What do you think?
Very good video thanks. One question,when you run double shielded flux you don't or can't reverse polarity,right? Where regularly on plain flux core single shielded ,no bottled gas you reverse polarity,correct?
One of things I’ve always wondered.. between flux core and using a gas , which requires more ventilation when welding. Could I use mig with gas and weld in a closed garage ? Thanks Gobear
A smart human would ventilate and wear a good respirator every second of hood time. You don't want to breath the fumes from any process. Just how I roll.
They both require ventilation, flux core you “see” the need more than you do with argon. The fumes and smoke from flux core go up right at your face and mask. There is less smoke and fumes produced when your using argon or C25 when mig welding but it is still produced. Argon and Co2 are heavier than air and will “fall off” your welding table and down to the floor. While the gases are falling away from you they can and will fill low lying areas displacing the available oxygen in the space. If you have an attached garage those gases can go into your house and displace the oxygen inside there. While it takes a fair amount of gas to completely displace the oxygen in the garage enough could accumulate to be a hazard to small ground level children and pets. Venting by drawing fresh air in from up high and blowing old air our from low when using gas shielded is always a good idea. Sometimes just leaving your garage door open a few inches and running a fan may give enough air exchange if you don’t have a hood or exhaust system in your garage. Additionally if you are using a respirator as good practice to filter out metal particulate or fumes you still must ensure that you have proper ventilation. I have seen body recoveries due to a respirator being used in an oxygen deficient environment.
Do you have a video that shows 'The Complete Welding Overview' ? It would be good for subscribers to be able to refer back to a complete overview. That would explain all the different processes (stick, tig, mig, pulse, with shield, without shield gas??) , transformers vs inverters, mobiles and how you would or wouldn't be able to add a mobile suitcase welder into your shop and truck. Great channel!! Thanks
We run metal core in all positions and on scale. What is the disadvantages? Is it a bad thing to run it in all positions? I would love to know. We run .45 hobart fabcor edge
This is the part of welding I like everybit as much laying down a beautiful bead! Gimme the "nerdy" stuff all day long! Metallurgy videos would be nice too! 😉👍✌️
For the gas shielded flux core test your wire feed was to low, voltage to high, and stickout to short (it is kind of hard to tell but unless you have rebated the tip into the nozel a fair distance it seems you are running about 3/8-1/2 inch of stickout, where as 3/4-1 inch is what most manufactures reccomend. if you were to run similar setting to what Lincoln, ESAB and BOC reccomend with they're FCAW-G wires you would be at around 600 IPM and 27-28 volts with 1 inch of stickout for 280ish amps, and that would drastically change the outcomes here I think. Also running the FCAW-G with the wire that low at 29 volts I strongly sustect would have slag inclutions in the root of the weld, as there isnt enough arc force to drive it into the corner despite the surface of the welding looking great.
How is your deposition rate higher than your melt off rate on the metal core? Possibly got your numbers switched? with the numbers as they are, your electrode efficiency should be 102.8%...
You would be suprised by how much the change in gas affects the process.. Also your voltage "legnth of arc" will also affect this more than you would think...
I was wondering the same and had to do some searching and reading. Solid is just solid wire with usually a plating to reduce oxidation during storage. Metal core has a core of a blend of metals in powder form, the outer sheathing is there to provide a current path for the arc.
Great information and very clear, tell you both are very knowledgeable. I would of been interested to see the self shielded wires used in this test also as comparison, i use a lot of shielded wire myself due to my workspace and price of gas in my area but its good to know both sides :)
So I was wondering, economy wise, are the throath thicknesses all the same? I imagine that with all parameters the same that one should be smaller with flux core
I am disappointed. As you mentioned in your introduction COST. Therefore why did you not add two columns. One for the cost of the wire and the second for the cost of the gas? And why did you run gas with the flux core wire? Does it not defeat the purpose? All this said, I did enjoy it to it's value. And thank you for posting and creating those videos for us the viewers!
Lol. I was about to say the same about 2 columns, but as far as the gas goes, flux core doesn't achieve spray without it, what got me was setting the mig to 40... flux core needs that, but mig only needs about half that... massive difference between consumption of gas, but as far as I can tell flux core wire is about $10/lb and mig is around $2-$3/lb... not sure about metalcore but I have heard its expensive stuff
I never run my Flux core that high. 30 tops... Dang thing most likely ice up. Cost of Flux core has a huge swing... Co2 is a cheaper gas the ag o2. But this was awesome to watch.

Would be cool to see a side by side penetration test and a bend test.
@Wroger Wroger Don't think so. Just changing the gun angle will affect both the penetration and bead profile. I bet there will be some interesting differences between these wires.
@@GAIS414
Ers70-6 wire is rated for 70,000psi, flux is rated at 72,000psi
That's only a 1/35th difference between the two

@Swampy Inhaling argon is really bad? Really? Really. I guess that's why we all die then eh, because 1% of the air you're breathing is Argon.

may i ask what feeder do you have on your dc400

Are the deposition rate and melt off rate switched on the board for metal core?
Rerunning the numbers. I think we may have just swapped the two when we recorded them on the whiteboard.
What is the difference between solid core and metal core wire? I have never heard the term metal core until now. Great video as always.
For the gas shielded flux core test your wire feed was to low, voltage to high, and stickout to short (it is kind of hard to tell but unless you have rebated the tip into the nozel a fair distance it seems you are running about 3/8-1/2 inch of stickout, where as 3/4-1 inch is what most manufactures reccomend. if you were to run similar setting to what Lincoln, ESAB and BOC reccomend with they're FCAW-G wires you would be at around 600 IPM and 27-28 volts with 1 inch of stickout for 280ish amps, and that would drastically change the outcomes here I think.
Also running the FCAW-G with the wire that low at 29 volts I strongly sustect would have slag inclutions in the root of the weld, as there isnt enough arc force to drive it into the corner despite the surface of the welding looking great.
This was a good video, agree with all your points, well done
How is your deposition rate higher than your melt off rate on the metal core? Possibly got your numbers switched? with the numbers as they are, your electrode efficiency should be 102.8%...
I weld with the metal core at work every day. its crazy to see the difference between man and machine
You would be suprised by how much the change in gas affects the process..
Also your voltage "legnth of arc" will also affect this more than you would think...
Great video, I sure wish the US would finally convert to metric though!

OK, I think I missed something - what is the difference in solid wire and metal core? I've heard of solid and flux core(s) but never metal core...

@@abpsd73 Yea... I think I'm looking at the same googled site you are. I'm reading the same thing. Funny I've never heard of metal core before...
Metal core is a cored wire that has alloy in the core rather than flux. Check out Select Arc's website. They have some good information.
@@Welddotcom So it's a metal coated by another metal? Isn't that the standard MIG wire? Where there is a protective copper like colored ER70S-6?
@@danl.4743 No. The core is not solid like a standard solid wire MIG
Great information and very clear, tell you both are very knowledgeable. I would of been interested to see the self shielded wires used in this test also as comparison, i use a lot of shielded wire myself due to my workspace and price of gas in my area but its good to know both sides :)
So why shield the flux core wire? I know double shielding makes for way cleaner welds than flux core alone but what was the point of it here?
So I was wondering, economy wise, are the throath thicknesses all the same? I imagine that with all parameters the same that one should be smaller with flux core
Flux core rocked this test. Production cost?
Does the 3.5 volt difference have an effect?
Pat ogarrety It probably does a little bit. The arc length should be a little bit shorter, but probably not noticeable when welding free hand.
Great video, very informative! 🤘🏽 anyone know the instrumental playing in the background during the arc shot? 😅
I am disappointed.
As you mentioned in your introduction COST. Therefore why did you not add two columns. One for the cost of the wire and the second for the cost of the gas?
And why did you run gas with the flux core wire? Does it not defeat the purpose?
All this said, I did enjoy it to it's value. And thank you for posting and creating those videos for us the viewers!
Lol. I was about to say the same about 2 columns, but as far as the gas goes, flux core doesn't achieve spray without it, what got me was setting the mig to 40... flux core needs that, but mig only needs about half that... massive difference between consumption of gas, but as far as I can tell flux core wire is about $10/lb and mig is around $2-$3/lb... not sure about metalcore but I have heard its expensive stuff
I never run my Flux core that high. 30 tops... Dang thing most likely ice up. Cost of Flux core has a huge swing... Co2 is a cheaper gas the ag o2. But this was awesome to watch.
Cause gas shielded flux wire not self shielded
