Day 2 was all about stainless. We began the day at 8am with approximately 90 minutes of lecture. We started with some basic metallurgy and went over the different families of stainless. We then talked about some of its physical characteristics and really focused on its thermal conductivity and why stainless wraps the way it does. Then we went into machine settings and techniques. Pulse was introduced and we were encouraged to experiment with high frequency pulse to reduce heat input and (hopefully) warpage. A little Q&A and then we were off and running. Bob cruised around all of the booths and did some demos for us. But really, it's been all about booth time. I've been skipping lunch and staying late. The six straight hours of uninterrupted practice has been fantastic. Here are some photos. Please be kind. With only a tiny bit (maybe an hour total) of previous experience, these are some of my first attempts at welding of any kind. The entire album can be seen

There's a lot of photos showing a ton of nasty welds in that gallery link I posted above. Fun stuff.
Thanks for reading!

That's cool! Looks like your first tubing attempt went fine. Stainless steel is difficult to weld as it is thin, and one mistake could scratch its flawlessness. Apparently your welding class experience was a hard one. But it will be worth it if you'll be learning stuff like this.

Hobart welding helmets combine performance with style and value while offering a welding helmet solution for every type of welder. here
I have missed your first welding class, could you please share the tutorial URL with me please? Do you have any youtube channel where you post your updates? I like your class very much. Thanks in advance.
It offers clean and fast welding with very less amount of smoke and minus any spatter. While looking for a TIG Welder, you need to consider a wide variety of factors. It is much more than just looking at the appearance or price point. You need to choose a welder that is fit for your purpose, is strong and durable and has the best price tag for your myhelmetsguide
