I’m an aircraft welder.. another tip would be to get yourself a copper plate, put it in the back making sure it’s tight and weld the hole in a circle one shot.. The weld won’t stick to the copper . Added advantage is that it will pull the heat out and helps with panel warping.

You need the right wire....use a gas wire, not flux core. Go a .6 or a .9 wire with Argon Shield gas set at around 10-12psi. The settings are all different on every welder but for sheet metal you'll be somewhere in the "1/4" region of your dial for amps and wire speed. Don't go more than a quick shot, work close to the metal, make sure it's clean bare metal and a good bare metal ground for your clamp.......and practice practice on spare stuff before hitting the piece you want to work on.

Here's a better way of filling holes... punch out circles of metal the correct size, then TiG or flame weld them in. If you must use a MiG, use .023 wire to weld in the metal circle. If the holes are on the small and fiddly side, drill them out with a step drill to a more manageable size and punch out the appropriate sized metal replacement disc.

I know here in the states "plug welding" is basically drilling a hole in a piece (like a floor pan replacement) so you can rosette (simulated spot weld) it to the frame rail, or something like that. This was a helpful video, but the person who asked about plug welding may have meant something other than the topic of this video.

I want to build a custom roof hatch on my van but wanted to know if I cut a 30x20 hole and push up a 2"x2"x 1/4" stainless steel angle frame from the inside if the ridge can be welded so that it's water tight and rust proof? The idea is at that clear hatch with weather striping where it makes contact would pressure down on the roof and water would have to penetrate that seal and climb up. Basically I would be using the top part of the hatch only and would secure t the welded frame..... Possible? Asking in that most hatches require a mess of caulking, drilling and backing and the space around the seal always looks like sloppy house roof work.

I learnt how to do this by accident trying to use a flat copper pipe as a backer which was extremely difficult and tiring trying to reach around to the other side of the fuel tank sump. I ended up just barely pulling the trigger and found that I could kind of "melt" a thin layer over the sheet metal then "blob" a weld and build off that fresh metal. You kinda end up chasing the blowout hole but eventually you overtake it and end up with a plug. It's more about having a really flat direct angle and touching the tip...let it arch and just dab the weld....don't try to actually weld it. Fractions of a second, jerk the trigger...then once you've got enough weld in there hit it with a proper shot and the weld will fill what void is left. It only works on the weld metal, not the think sheet metal.

The rest i did were ok but that warpage and big hole I made frustrated me. I waited away for now. Can't get behind this area so it'll need to be pulled out with pins and a knocker. I haven't welded this much in 30 years, I should've practiced a few days first.

To do a plug weld with two pieces, make sure one is flat and one has a hole. Both pieces MUST be clean bare metal and where you clamp your ground. Use welders vice grips to clamp the piece tight together. Set up your welder for the metal thickness and wire...sheet metal usually takes a .6 or .8 even .9 wire. A gas wire with Argon is much easier and cleaner to use. Get the wire speed right, the amps right for the thickness, get the wire close and almost vertical and pull the trigger. Work it around the edge then into the centre....you might need to try twice or three times because it'll heat up and risk blowing through before you fill the hole. Once you've filled it, use an 80 grit flap disc on an angle grinder and grind it down flat....take it easy, grind...back off...grind...reassess...grind etc. You'll then have something similar to a spot weld.....practice on some spare pieces until you're comfy with the settings and technique.

Jonathan Cooling In many cases using a flux cored wire will help with rusty metal. In my opinion about 50% of the problem with mig on rust is that getting a good circuit is almost impossible. A wire feed welder keeps feeding wire at a constant speed even when the ground breaks up or the wire makes poor contact at the puddle. If you use like NR-211 wire you weld with electrode negative. So if you get the area cleaned up good that you are going to ground to it will help. There are always 2 sides to your grounding clamp. The side that the cable leads into is the more conductive side. Always hook the more conductive side to the spot you cleaned. I know that sound obvious to the point of being stupid but I have seen many welders do it wrong.
@mariataylor276

What usually happens with this blobbing it does not allow weld to go deeper that the thickness of the panel when you grind it back flush you still have a hole albeit smaller, meaning there must be parts of the hole that are thin !
