Hi Lynn
3 MM seems thin, check my math guys that would be .11811 inches thick that's less than 1/8 of an inch. Floor plates in CMP cab are thicker than that.
I've welded 1/4 inch diamond plate very successfully with Mig welder using CO2 or CO2-Argon with a 110 volt machine. As suggested weld in short sections to prevent warping. If you can find an old brass kick plate I have had very very good luck using them as a heat sink behind the weld to prevent warping. Brass or copper are good because the weld won't stick to them. If you don't have brass plate I've been using scrap copper pipe just slit it and flatten it out.
Another good heat sink trick is wet toilet paper scrunch up and stuck to the steel about an inch from weld.
Before and after pictures of the repair would be interesting.
Cheers Phil
