MIG Welding Thick To Thin
#welddotcom
We had an epic debate in our FB Group about MIG settings in welding 1"plate to some 1/8" plate so our advisor Chris decided to test all the suggested settings!

I was told by some old head, Thick to thin is all about where you aim and how you wash that heat over into that thinner plate. And since you spend a majority of time on or pointed at the bigger plate, u need to be hot enough to melt in. :) helped me a lot even with tiggin thinner stainless etc.

Sounds like good advice to me. I teach the same thing. Set your machine for the thicker piece to ensure penetration, and then focus heat there, and use your movements/puddle manipulation to work it into the thinner piece as much as needed, without blowing holes.

Top notch vid! Good explanation of the limits to globular transfer at 24V and 400 WFS. Yikes!! Excellent, excellent.
I generally shoot for somewhere between the settings for the two thicknesses, but air on the side of the thicker plate settings and use my aim to avoid blasting through the thinner plate.
Interesting , thanks.
Outstand Mr Ewing, I really like your presentations.....cheers from down in Florida.....Paul...hey wait, I sure don't remember giving any recommendations....but maybe I did???? Chris Wentela and I used to work together ....he is a great guy....

What's the best welding you can do on these levels of thickness with a cheap Harbor Freight Flux Core welder?
@chrisewing3272

Best thing... tie a long rope to the welder, and use it as a boat anchor Not helpful, I know. Those machines are generally only good for up to 1/4", and so your only chance would be to max it out on the heat setting (voltage) and find a wire speed that doesn't just bounce material off of the top, then do multiple stringer passes until you've reached the desired weld size, making sure to clean the weld between each pass.

you might get away with 5/16 or 3/8 plate if you ran vertical uphill and maxed the machine out. Otherwise you have to bevel it and make multiple passes.
so now u just have to cut them open and see how much each was pening LoL
It's definitely possible. I did it for years. Work your puddle into the thick then float in the thin.
Many a true word…
Did I miss it or did you not mention...what size wire were you using? thanks.....Paulie Brown

@@chrisewing3272 I rewatched, and yes, it was not in there.....kind of important, as you can figure the amps if you know the IPM and diameter....give me a shout on whats, and I will give you the formula if you do not know....Paulie...or should I post here so all can see how to figure amps, not every machine will have an amp meter, and some that do, you have to be watching as welding, it is handy to know in advance just how much heat you will be using......and amps are heat......
That first setting is .5 VOLTS* higher and 20 inch/m slower than what I would use welding 18 guage sheet metal together. Some othe others I'd use welding 1/8" or 1/4" angle to sheet metal. The setting you suggested is what I would have used E: fixed a word

Pieshka, you mention .5 amps, where is the amp setting on that machine??? you do know that amperage is controlled by wire feed speed....and is not a setting on a CV welding machine like a CC tig or stick machine

@@pieshka4509 I think the disconnect Paulie is highlighting is that you're talking Volts, not amps. I agree that those settings were on the low side for sure. Amperage is controlled by wire feed speed, but also affected by wire stickout, as a greater distance increases resistance. If you watch your machine in real-time while it's welding, the IPM will often display AMPS.

Tig would absolutely be preferred, and I'd pre-heat the 1/4" first. Not to say that it "couldn't" be mig welded, but it would certainly be a bit more challenging.

Ive done similar with MIG, I had to run it very low, with a small weave to spread the heat around. I havent tried it yet but I think you can run hot and just travel REALLY fast, tricky to get the puddle established and keeping that small bead though.
I don’t really understand why you’re dragging your runs when there’s no access issues or anything.

I think it has to do with the preference of the presenter and unless they are doing a comparison between push or pull, you will get one or the other....

Dragging has a tendency to increase penetration and buildup, while pushing generally leads to the opposite. I suppose I could have chosen either way, but in an attempt to be "scientific" I simply wanted to ensure they were all done the same way to get the best comparison. Great question though... guess I gotta go do another one now, lol.
