In no particular order, these are the channels I like and why....
ChuckE2009. - Just cool as hell, very informative and 1st place winner in number of weld vids.
Weldingtipsandtricks - Jody because he's a pro and an excellent teacher.
Kevin Caron - A gifted metal artist that stands above all others. (See his website pics). A great teacher.
WeldFever - an up and coming new YouTuber that has a lot of potential for his welding vids.
DarrlingtonFarms - just a down to earth Farmer that welds and makes neat videos.
FieldRes - One flew over the cuckoo's nest, albeit a bad azz welder!!!!!!
Musher Deeds - A small one man shop welder that has made some damn good videos.
xAZAZELx13 - The BEST mass produced pipeline welding videos you'll ever see on YouTube.
Alvarez Metal Works - Another one man shop welder trying to get his star on YouTube. Great channel.
TheProRancher - This guy has made a limited number of welding vids, but they're descent. But, he makes kick azz vids about working on a real ranch! Plus he makes custom branding irons and is a hunting/gun fanatic. :drinkup:
Last but not least......
SV Seeker - The most incredible self taught and determined fabricator/welder I've ever witnessed on the internet! He's documenting a gigantic welding job on his front lawn!!!! He's making a huge all steel "battle ship" (okay, a pleasure vessel) on his front lawn with his wife. They've been at it for a few years and it's obviously their "life's mission. Noah would even have envied this Ship of fabricated steel and beauty. He has hours of video documenting this enormous task with this monster metal sea vessel. Heck, prior to this, he built and "sailed" a metal submarine!!!! He knows how to follow blue prints and build everything from bulkheads to fabricating his own bronze propellers! Plus, he's doing the majority of the welds with a Miller suitcase welder!
