Does anybody have experience stitch welding 24 guage 1018 cold rolled steel sheet with a mig welder?

Thanks,

Pete
 
Mig welding 24 ga. anything (steel, stainless) isn't going to be easy with most mig guns. With something that thin, blow-out is a big problem, but it can be done. Heli-arc/tig might be the way to go.

Try to weld down-hill. Try short arc with 90/10 Ar/CO2.
Go fast-kick up the volts.
 
.023" Diameter mig wire is available that should weld 24 gauge.

Other diameters may work but with more effort. Butt joints will be difficult. Laps or edge joints may be easier.

Welding 24 ga. 1018 can be problematic. Our answer was to forgo speed of welding this type of material(Mig)for inspection/vs. quality welds.That would be Tig welding with small diameter electrodes,filler metal if required.
A good Tig welder should be able to make up the produtivity that would be lost switching from Mig to Tig welding.
We have been able to do so,with no outlay other than needed equip. for small dim. steel. Hope this was helpfull.

If this is an automotive application (i.e highly automated), I would look at low current Plasma Arc Welding. You get all the same advantages of GTAW (TIG or Heliarc as some say), but you get better arc starting. In some GTAW applications at low current you can blow away base metal when the arc transfers. PAW equipment is just slightly more expensive than GTAW and automation is often less difficult.
