MIG Welding Tips: Exhaust Tubing V8TV

http://www.v8tvshow.com - Here's a quick tip on welding exhaust tubing with your MIG welder... do it HOT and FAST! This technique shows how to burn deep-penetrating, low-profile welds that look great on their own or can be easily dressed for polishing or coating. The secret is to use high amperage (or heat) and a series of quick tack welds, and give the work time to cool between each tack! Resist the urge to seam-weld the whole tube... you'll have to run your welder too "cold" to prevent burn through, resulting in welds that are stacked high on the tubing, not only looking poorly, but also not penetrating as deep as you'd like.

Porosity much?

[V8TV]

@hypnolobster Nope! And not one has cracked or fallen off!

Hello there.

Thanks for the tip & i got also a MIG200 machine and after watching this video i did a better job on thin metalsheets, i was thinking it would go thru the metal but by shuting off the gas & using more heat (like you told) it helps ...

THANK YOU BROTHER!!!

[V8TV]

@ttaattuuaaddoo71 Sounds great, but I wouldn't recommend shutting off the gas, just keep the gas flow set around 20 psi to keep the welds clean. Glad we helped!

[ttaattuuaaddoo71]

@V8TV OOPS my fault...

It wasnt totaly shut, i just copy-paste your settings, so 5 mainheat, 0 pausetime, wire speed 5 1/2 & weldtime 1/2 :"P

Maybe my tags did not look as good as yours but after grinding it looks good & i had no open spots... Thank you very much!!!

[V8TV]

@ttaattuuaaddoo71 Gotcha. Feel free to play with those settings a little to make them match your material, you might have something a little thinner or thicker than we had. We'll be posting a video on how to set your MIG welder quickly and easily soon. How do you like the MIG 200? Ours is one of our most-used tools, and it's been going strong for almost 6 years now! Great machine.

fuck get your cone closer, your gunna go through a shit ton of contact tips welding from that distance

way to much heat you would get the same result with a consistant weld with the right aperage your machine should have the right settings what happens when your weld is to hot it gets brittle think of steel when you have cold roll steel you can work with it , it can bend and be worked.. hot roll steel is like what you are doing is like glass sort of it is weaker and can shatter... a good weld is a good weld and your method has way to much penentration... just my advice i weld all day long...

Man you guys have the most interesting videos anywhere on Youtube, glad I discovered this channel. Most of this stuff is over my head but I still love it. Subscribed.

Wow You are profess

[sibedogg]

Wont to much penetration make it britle as fuck and make it break again tho?

I used my Miller 251 at 19-Volts 120 wire speed tapping the trigger.. Very little cleanup and came out MINT! - I linked over to your Video also.. Thanks! -Rob

Great Vid! Thanks!. Quick question: What is the advantage of sand blasting after the weld? I have a sand blaster, so I am able to do that. I hope it's not a dumb question....(smile).

Thanks in advance! I subbed your channel. Lots of good stuff on there!
