Welding is awesome! I think it is a great skill to learn, fun, and once you know how to do it you can find all sorts of useful things to make. I’ve only done a little bit of welding, but I’d second the recommendation to find a local community college class or something similar. Learning from an instructor and getting direct feedback helps a lot. Also, practice is really important. Whichever way you learn, get plenty of material to practice on, and do as many practice welds as you can.
I’m not an expert by any means, but I’ve seen some you tubers doing pretty horrible welds. So, if you watch videos for tips, try to find people who have experience, not someone who is just starting to learn themselves.
