how the factory welded ?

Here's the opposite end of the rail I posted earlier. I'd say it was a two man job, sober worker on one end, after lunch buzz on the other!

That's a huge difference.

DC low voltage and small rod will weld sheet metal.

If you can find 1/16 rods possibly 6011 that would be good for thinner sheet metal. Using straight polarity which gives less penetration is another option. Ive welded stainless commercial sinks using 1/16 rods. Vertical up requires a higher skill level however on that thin a material. MIG is really the only good thing and I've only seen guys gas weld panels in if they didn't have a MIG welder. Depends on what thickness sheet metal were talking. 1/8" plate is referred to as 10gauge and goes from there. Im basically referring in this thread to thinner sheet then 10,11,12 gauge
