My Son Came Home With a Brand New Spool Of .035
Solid Welding Wire That Was Given To Him,Ive Been
Welding With .032, What Difference Would I See
Welding Say a Patch Panel With The .035 vs .032
Pro's Or Con's, Would I Get More Buid-Up If I Was
Welding Say a Gap Between a Fender and Door? And Wanted To Build Up The Seem on The Door Or Fender
To True It Up? just Curious!
Thanks,
Allen

larger wire diam. takes more amps to melt and tends to result in more heat transfer to the area surrounding the weld, thinner wire tends to melt faster and impart a bit less heat to the surrounding area, obviously weld gun movement speed and wire feed speeds and amp settings can vary the results also, but smaller diam. wire tends to localize the heat to some extent, thats one reason youll tend to use thinner wire on thinner sheet steel as your going to use less average amps and less over all heat on a smaller area to generate the molten weld pool.

It depends on the situation. Generally speaking - as long as you don't have huge gaps between the edges of the patch panel and the vehicle, the smaller wire will make a smaller puddle - which is easier to grind. If you have larger gaps or you aren't that experienced welding, you can go with the larger wire.
It is better to use something like ESAB's EZ grind welding wire (ESAB is a company that produces welding products) that is specifically designed for sheetmetal repair. Using any old welding wire is likely to cause a lot more work for yourself.

Back in another life before I retired, I bought .023 for sheetmetal and .035 for heavier metals such as hard frames.

I Must Be Getting Dyslexic Cause I Use .023 Not .032 (To Much Teflon On The Brain, Nothing Sticks
Anymore).
Anyway Thank You All very Much For The Feed Back!
Grumpy, Makes Total Seance About Applying More Heat, Thank You,
I am Familiar With ESAB and Did Not Know About Their Wire Being More User Friendly In Grinding It Down I'll Have To Check It Out!
Thanks Guy's

I tried the EZ Grind once and couldn't tell the difference.

I usually use a 1/16" thick 3" diameter cutoff wheel in an air die grinder (either straight or 90º) on sheet metal. I've tried both cheap and more expensive discs. The more expensive discs last longer but they don't cut better, and it's a tossup on cost. In other words, does a disc that cost twice as much last twice as long? Yeah pretty much. Your mileage may vary.
After the grinding, I use 36 or 50 grit Rolocs on the 90º air die grinder. Sometimes a flap wheel. You can't switch to a sanding disc too soon as you'll cut into the surrounding metal.

Years ago when I first started playing with a mig, I had an old timer (no offense Vaughn) tell me to start out with the bigger wire and then after I got the hang of it, switch over to the smaller wire. I never understood why but damn, now I get it. Duh, hey?

I tried that myself and actually thought it was harder to grind. the cost was a little high, if it was easy may have been worth it.

Rick, I've noticed similar results. But the added benefit to the more expensive discs (I typically use the ones rated for stainless) is that because the disc lasts longer, you'll have much less brown abrasive particulate floating around in the air, and less frequency in changing out the discs. When I see the no-name discs at flea markets any more I don't even slow down to look..

I'll try those if I can find them reasonably.
Thanks.
I never really thought about the amount of aluminum oxide and resin in the air vs. steel "dust". I'm not convinced there's anything noticeable.

If you use some of the flea market specials, you'll notice considerably more "brown haze" floating about.

Hal, I'm sure they could be found online, but my local welding supply is normally in line with pricing found on the net, so I just keep the business local.
