MIG welding class info

Decided to stop my hush of the TIG welding thread.

To those of you signed up for the class, thank you for your interest in MIG welding!

We will begin in a classroom (I believe it will be classroom 3.) and go over some fundamentals. Then we will move to the hotshop where everybody will get a chance to practice what we have talked about. I want everybody to get a chance to see what good welds feel like and also to experience some issues, so that when they happen in real life, you’ll recognize that something isn’t right.

We’ll go over what welding is and what welding isn’t. We will talk about materials and processes. Even though the focus is on MIG welding, we’ll talk about how welding processes differ from one another.

Please wear appropriate clothing for the class. I encourage the use of PPE, of course. While it is common to find people, myself included, welding in short sleeves and shorts, it is not a best practice, so for the purposes of encouraging safe welding, I would like everybody to wear the following if possible.
Long sleeve shirt - preferably not synthetic
Long pants - preferably not synthetic
Closed-toe, leather footwear

We have the following at the space, but feel free to bring your own as it may be in better condition and more comfortable.
Welding gloves
Hearing protection
Safety eyewear
Welding hood

We will have the exhaust fan running, but dust can/will still be in the air, so if you wish to use a dust mask, we have (or at least had) some in the cabinet, but you can bring your own if you desire.

I will supply metal for welding and all example materials.

I’m looking forward to seeing everybody Saturday evening. If you have any questions before then about the class or expectations, please feel free to reach out to me on the forum, via email, or by phone/text.

Thanks to all who participated in the class tonight. Hopefully it was informative and fun. Let me know if you have questions as you begin your welding journey!

For those that did not have a waiver on file, I didn’t figure that out until last night after the class so I will send a link to that waiver to be filled out.

I also realized trying to get through the whole class in a 3-hour window that I skipped over the most practical way to test a weld. Well etching the weld is a good way to test penetration and look for porosity, to test the strength of a weld is much simpler. A bend test does that. Commercially a bend test would be done in a fixture with a hydraulic press but a simple bend test can be done by putting the weld piece in a vise and hitting it with a hammer to see if the weld breaks. There are YouTube videos that show how this is done or if you would like more information on it just reach out to me.

Thanks again. It was a great class.
