Metal Shrinking disc 

Fantastic job Roger! I think those welds look beautiful and the finish is second to none. Thanks for sharing my friend.

See Carter Auto Restyling. That's some great example of everything without Bondo. Amazing metal work with simple tools and elbow grease

I’m on a similar journey, your instincts are good. You’ll have it figured out in no time. 👍

I mostly TIG outer sheet metal, what I found is unless you are by an edge you will have to work it a bit. Some tips on your weld looking at it quick is and honestly it looks good but some small criticism..... You are using too much filler for 18 gauge thats where the too much heat is coming from melting the filler wire. I get my puddle formed and walk it down the edge and add only when I know it won't hold. Speed is your friend here like others said, if you see any of my welds the heat affected zone starts off and ends the same, yours seems to keep building so speed up or lower amperage as you keep going to keep it consistent.. I usually run 45-50 amps foot pedal controlled, 18 gauge but I have videos where when I am TIG welding running it down to 20 amps to control the heat. There is a lot of examples on my youtube from covering door handles to gapping whole cars using mostly TIg. I also don't use pulse. Try a 1/16 inch filler wire I know it larger then assuming the .030 your using but you only have to dip so less often and can drag the puddle further with that filler. you 1/8 inch tungsten? I like a number 5 cup 10 cfh flow and I am also a bit spoiled with a water cooler but have got the same results with a #17 air cooled torch. Good luck its just practice

Check out Carter Auto restyling on RU-vid. He is chopping a 1950 Chevy pickup and obviously the metal is going to be a little thicker but same principles apply and he uses TIG for all of his finished welding.

You are becoming a Master :) Good to see you Roger.

Tig welding you want the best fitment you can possibly get small tac everything in place then single weld from one end to the other. Tig is very different from mig the way that it cold and its hardness

Brother! You are obsessing! That looks great for a guy who is just starting out. I am no expert, but my buddies who are, always say TIG welding is really about rhythm and feel. Takes a long time to really catch the groove. I've seen pros that can't do that well on thin metal. Only advice I would give on the welding is just do shorter bursts. 3/8" instead of 1". Smaller D's. Smaller filler rod will also help with the build height, but you will need to move fast. Also always start your weld puddle on a tack bridge or the end of the previous run. But overall that is a fantastic outcome. Head high Roger!

Watch Karl fisher make it kustom , pacific arc welding

I also did see in one of his videos on this car (maybe the one I linked) he used the air saw to open up a gap between the panels as well.

You are a visual learner💪👍

You will have everything figured out for your next car

Channel: retropower, Video:auto focus episode 2 butt welding panels, this is a pro shop so knows their stuff in tig welding car panels! Worth looking at their channel because they restore cars to the high quality ok it british stuff but they do nice stuff!

Bauer 20V 4.5" grinder from harbor freight runs at 7000 rpm. that may work better.

I also forgot about ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TV1qyVftTy0.html he does a lot of tig work, and it comes out great. Your techniques look very similar.

What are you using for filler wire? Next time run some wire out of your mig and use it takes much less heat and doesn't add so much metal!

Blah blah blah... get to the part of the shrinking disc. As the title suggests.
