I am new to welding. Only took me 74 years to get it around to it.
Bucket list.
You are a great teacher.

Thanks

Great advice. I'm a big fan of thin-wall square tube to make brackets and carts out of, usually 14-16 gauge. The only other tip I would give others for this kind of work is always tack EVERYTHING first before fully welding a joint. So long as you can get the MIG gun in position to make the weld, tack EVERYTHING, as in the whole structure together. It will pull/distort a lot less when there is "no where to go". Obviously when things are clamped tight to a fixture table it helps, but something high off the table might not be able to get properly secured like a part down close to the table. So even then, tacking every single corner will really help things. Simply avoid wanting to just get-in-there and start welding overboard; it will kick your butt in the end when things pull and you have all sorts of gaps in other places you didn't anticipate.

I’m new to welding. Building a few side gates out of 16g square tubing. Thank you for putting these most informative videos on your channel.

As a beginner Tim is my go-to guy to get me started. Gets right to the point and makes it clear and easy to understand.

Really good information. My son and I are just getting started in welding, and have never really MIG welded, but just purchased one. I did some Stick welding in High school over 40 years ago. Now my son is fixing to take a class also. Thanks so much, really appreciated! 👍👍⚡️

Clear, concise, thorough. Another great video. Thank you, Tim!

Thank you so much for these videos. I'm rewatching this one after welding a piece like this for a job and was just offered it. I haven't worked with tubing before and can't wait learn to do these better.

Thanks Tim for another excellent video. I'm still learning and slowly getting better with your help.

Nicely shown. You make it look easy. People simply refuse to practice, I find.

[apexcustomsmokers]

Great info as always Tim, I use heavier tubing for my smokers and forget how easy thin wall stuff blows out lol. But that's where the practice welds come in like you mentioned, no shame in laying down some practice welds if you haven't welded a certain metal, joint, thickness, etc. It's actually silly not to in my opinion. 👍

Fanstastic work 👏👌 thanks my friend👍👍👍👍

[nicholasqa]

I would love to know more about figuring out the best welding sequence Tim!

Something i noticed about the welds @3:45 is that you are faster in the middle of the weld then at the ends, which while the metal is still molten looks concave and not even. Does that mean the welds are stronger/have more penetration at the ends than the middle?
