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.

I take a piece of copper pipe and hammer the end flat, then bed it to whatever angle I need to reach the backside of the hole. This gives a nice long reach into confined spaces

he explained at the beginning that he will usually do that but sometimes you can't get behind what you're welding. which makes sense to me since a lot of welds on autobody panels are closed on the backside.

Great quick tip style video and nice demo also. Thanks for helping people and making videos with the real techniques welders use to handle tougher jobs. No matter what anyone wants to say this works well.

That video is a blessing! My friend told me about that and then she showed me that trick! Very useful! May Kemppi bless you!

Thank you so much. I’m a novice welder and this was really helpful. Straight to the point. Thumbs up and subbed.

Hey man, just want to say that I recently picked up a gas mig welder, and you single handedly have taught me more than any other KZreadr BY FAR. Every time I type in a how to on welding your videos are the only ones I watch

I just did this today on my project car, it was my first time welding for real. Someone riveted in those ugly rubber strips on my Mk2 jetta so I had to close them up. I figured out to use this exact method after blowing out a few holes. I thought it was wrong but its nice to know it was an acceptable way to do the repair.

This will help me so much during the restoration of my 83 Chevy k10 pickup. Someone probably decades ago drilled 8 holes on both sides of the bed for what I assume was bed rails. Thanks so much

Very cool. I have a bunch of holes that were drilled in my M38 Willys. The techniques you demonstrated will help me get started. I'm going to start with something that's out of plain view and then proceed to the outermost panels. From Texas, thanks for the fun. :-)

When i first started i remember all the fun i had chasing holes round a panel just don't generate to much heat just takes a little practice like anything but a good technique to have in your box of tricks

This is awesome. Im working on my 73 Lincoln Mark IV and did away with the vinyl top and it's chrome trim. Been trying to fill all the holes and ended up blowing a few holes so going to try it again and get it sorted! Thanks!!

Thanks. I’m filling in the trim holes on my father’s big window Ford uni-body truck that’s getting a coyote swap. Super helpful

I figured this technique out last night by trial and error of blowing holes it worked really well and it keeps a lot of heat off the panel to prevent warping

Brilliant. Ive learned this already the hard way ha ha ha and its good to see a very talented fabricator do this so precisely!

Great tip, I’m currently in the process of doing a “shaved engine bay” will definitely try this technique out.

Glad I found this video! Technique worked with flux core. Keep up the great work!

@110WeldnSteelworx

I believe, and correct me if I'm wrong, flux core is a pretty hot method of wire use. I would lean towards 7525 mix for carbon steel. possibly run a little more cup and stick out away from material to keep it cool. I'm getting ready to add louvers to a Jeep Hood, a little sketchy about warping no concern with filling the holes. I wanted to see if urch touched on it.

I am new to welding this tip was really helpfull. Thank you!!

Thanks for this I'm going to be practicing on an old car door soon doing spot welds.

Great short video, I really appreciate your awesome!!

Great real word demo of whats possible.

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've been using this technique to fix hole I blew through doing some rust repair on my truck. Thanks!

great video.. thank you very much..

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.

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.

Any chance you can explain further on the MIG settings? Thanks ever so much!!

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.

Use copper block in back myself,works perfectly

good tip about the aluminium

Thanks!!!

Nice.

Thank you.

I just did this this afternoon and figured out the same process but wound up getting a good warp and a sizeable burn through hole in one of several drilled holes I was filling on a 40s Chevy quarter panel area. 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.

Those are nice clean holes. Now assuming most people have rough rust holes is it best to drill through them to create a good clean hole? Helps to remove bits of rust too......

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.

Helpful video as usual, thanks. What did you use on the grinder to smooth the welds please?

What wire speed are you using?

I noticed that the metal you are using is a lot thicker than what they have on car fenders now days. In fact my fender is so thin that it looks like tinfoil. How are you going to weld that?

New to welding, only had it a couple weeks. I am wanting to plug some holes in my trunk on my 93 Miata where the old rack was. What would be a good ballpark for my welder's settings? Any and all help would be appreciated!

@olivedrabgarage6243

4 жыл бұрын

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.

How do I make the rust not come back? Lol...getting a wheel well repaired with new metal and people keep saying the rust will come back. Esp at the weld spot in future because water will somehow get in...really bummed about this because I just got the car smh.. can I Plasti dip over the repair to ensure no water ever comes into contact with the weld repair again? Lol. Best options to make sure the wheel well doesn't rust again at the weld spot ? Thanks for any replies. Need some optimism lol. Going to be paying $800 for a wheel well repair ( cut out old metal and weld in new )

Top tip. I tried this on a rusty lawn mower deck. It was ok on the surface, But rusty beneath the surface so kept blowing holes as iron oxide messed up the weld. Any tips for this scenario?

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.

Can you be further away next time?

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 !

But what about the gas reaching the weld when you hold the torch that far back??
