MIG vs. Flux Core vs. Metal Core

#welddotcom
We are comparing solid wire spray versus gas shielded flux core versus metal core today with a little help from Jerry Mathison at Select Arc. To compare the 3 wires we're going to calculate:
Wire efficiency
Heat input
Melt off rate
Deposition rate

    @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.

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.

    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%.

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?

    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...

    Science! Cool. Can you bend test those coupins and see if there is any difference in strength? Cut/etch/bend ?

    Would have like to have seen cross sections to show the penetration of each process.

    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.

    SirFuseable check out some of our other videos. We’ve done a bunch on self-shielded flux core. Thanks for watching man.

    Would the solid test be .035 or .045? Just curious

    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?

    Im curious about the cost of using gases, esp vs. flux no gas.

    Flux core rocked this test. Production cost?

    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.
