One of the best sheet metal welding videos I have seen. Thanks.
Wow, thanks ! Glad you enjoyed the video. If you deem me worthy, I'd really appreciate it if you could share out my channel on your social media so I can help more people. Thanks for the watch and welcome to the channel!
Thank you! I'm soon to start making the metal wings of a sculpture and your video will help me HEAPS!
Glad I could help! Good luck with your sculpture! Thanks for the watch and welcome to the channel!
Great video! Not sure if I've seen anyone else on YT show the air cooled welding technique. I never thought about the actual physics of why thin metal warps which was interesting. I would like to have seen a demo of "hammer welding" tack welds while they're still hot to flatten them.
Thanks Vince! Yeah the heat is what warps everything up so minimizing the heat, minimizes the warp. I was thinking I might do a hammer welding video with gas welding but MIG would work too. Thanks for the idea and welcome to the channel! Cheers!
Following the full series and learning a boat load every time, thanks x 200%
Awesome dude! Glad to hear you're loving the series! If you deem me worthy, I'd really appreciate it if you could share out my channel on your social media so I can help more people. Cheers!
Thanks a lot for these videos. In depth and very educating for us beginners and even those further along. Best regards from Iceland.
I'm happy you're enjoying the channel dude! Glad to help everyone out and share my experience. If you deem me worthy, I'd really appreciate a share out on your social media so I can help more people. Thanks in advance, cheers from Canada!
Awesome and very helpful video on welding sheet metal. Thanks so much for taking the time to do this!!!
Glad you enjoyed the video Jim! It's all about learning new skills! Cheers!
Once again an excellent video! Thank you for making these.
Glad you enjoyed the video, thanks for the watch!
Outstanding. Thank you for sharing the excellent tips and demonstration
Cheers Jonathan! I'm glad you're enjoying the content and my teaching style. If you deem me worthy, I'd really appreciate it if you could share out my channel on your social media so I can help more people. Thanks in advance and welcome to the channel!
Fantastic video! I rarely leave a comment but this is going to come in so handy for my E30 restoration! Quick question, is there any benefit in doing the flange/spot weld technique along with running a tack, pause and move technique along the flange join?
So a combination of method 2 and 3 from the video? I hope this makes sense
Thanks! Glad I could help you out and you're enjoying the content. If you deem me worthy, I'd really appreciate it if you could share my channel on your social media so I can help more people. You won't gain much for fully welding the seam as well as the plug holes, unless your vehicle has major horsepower and your twisting panels. You're going to seam seal those seams after to keep it water tight so there's no need to weld it water tight. Thanks for the watch!
On the spot weld and flange technique how would you hold down say a replacement floor pan panel? Would you apply light pressure by hand?
Yeah that works. You could add heavy weights, temporary screw, magnets, or a clamp through a hole if it's there. Just make sure the 2 pieces are tight before you plug weld. Cheers!
The best!!! Emile? Both a pick-up line and a name in one.
A meal? Emile!!! lol.
So if she says no... you say, what you mean no? Izza ma name! Emile!
I crack myself up.
Never thought of my name as a pick up line....
Chill blocks?
Yup, you can use them. On thin sheet metal, you'll still need some technique or it'll blow through and chill on back side.
can I use my century 90 flux cord machine on 18GA sheet metal?
Technically...yes. I'm not a real fan of flux core as it never looks as nice plus you have slag to chip off. Same rules apply as it is easy to blow through and tougher to seal holes with porosity. Thanks for the watch!
@@wayofthewrench so would it be best for me to use a thicker gauge metal?
@@wayofthewrench Making a Batman mask!
Easier for sure but I would give it a try and see.
Yeah dude, that sounds epic!
