Hi Roy,
Thanks for your video's so far. Seemingly not much feedback yet. I'll throw a few ideas for what I'd like to see.
To set the scene. I live on the east coast of Australia. Small farm, small town away from everywhere. I've owned my TIG inverter for about six months. I weld several times each week and completely taught by Jody Collier, Bob Moffat, Mr TIG and Justin. It's going OK.
1) Thin material. Steel, stainless and Aluminum. eg. I have some 1mm cold rolled sheet steel in the shed. I have an old land rover with door frames that need attention. I'll be replacing rusted sections etc with that sheet. Old material to new. Thicker vs thinner. Interested in your thoughts. Maybe some examples of thin material and sheet metal.
2) Once again on that Land Rover (Aluminum body panels), I have a split of the material on a rear door. The door skins are commonly replaced but I'd love to weld it. I could send a photograph if that assists. Cleaning up the paint. What about the any corrosion in the crack which I can't get to. Do we risk increasing the gap to clean it out?
3) Gap filling. Things are far from perfect around here. That being said, I'm always trying for the best outcome considering time. Any examples of gap filling techniques would be appreciated.
4) Thicker material, commonly steel. My inverter is 200 Amp. It wasn't my intention weld thicker material but, the results seem pretty good with multiple passes. Jody has covered this in some video's. It's always good to see someone else.
Just a quick note. Sometimes is the small things you may add that register the loudest. Your advice on the choice of silicone carbide strip disks for example. Brown vs blue. Jody was welding up some steel tube in one video here. Don't get the pool too hot. The contaminants will come in from the back side. They are eureka moments for me. I see that pool swirling with contaminates sometimes.
5) Preparation. I'm about to weld some steel stub axles into some galvanized steel pipe. That's all we have in the steel rack. I'll obviously be grinding back the zinc but how far? Do I really need to do the inside? :-) Of course I do... but what does it look like when I don't? Spatters all over the tungsten and my nice new gas lens.
6) Filler rod feeding. Brad did a segment on that which I appreciate. It's always a struggle, particularly when you're not welding every day. While I may practice feeding with a glove, the moment I'm welding, things are different. The moment I concentrate on filler feeding, my arc length mysteriously increases. It's automatic. What are your filler rod feeding tips.
7) Anything difficult. Anything not guaranteed of a good outcome. Sometimes I think my outcomes are not so good.... but are they really bad for the time invested? There's an episode of Mr TIG welding a replacement head light surround. Lots of tacks, then welding between the tacks. Lot's of time spend cooling the material. The outcome was not consistent.... but very effective. Was it ever going to look like a machine weld? What are realistic expectations.
Anyway, there's a few ideas of where I'm coming from. Hope this helps.
Regards,
Michael Kearsey
