Hey Gary, I like the way you are paying attention to the important details such as improving the injector angle. Obviously the manifold is cast aluminum but what alloy are the bungs made from? And, which filler alloy are you using? 4043 or maybe 4047?
I appreciate your reply and also appreciate it that you’re sharing some of the cool stuff you’re working on. Regarding welding aluminum, I was also curious if you have a favorite type of tungsten and grind angle you prefer (or do you ball the tungsten)?
Sometimes I get to work on boring stuff and sometimes I get to do cool stuff...LOL... I'm trying to figure out what stuff might be good to put here on youtube and not put up a bunch or garbage that nobody is interested in. About the tungsten, I use 2% ceriated and 2% Thoriated. Usually the ceriated on DC and Thoriated on the AC (aluminum) stuff but honestly, I've used both those on both types of material and they work fine. I would say my angle is 30-40 degrees taper, I use an Inverter machine and the tungsten doesn't need to be "balled", the old school transformer type machines use a balled tungsten on the aluminum. I hope this helps answer your questions, Thanks again for stopping by my channel!!!
Gary, thanks for the additional feedback. I ended up needing to butt weld some 1/4” 6061 tonight and I ended up using a 2% lanthanated tungsten because that’s what I had laying around. I used 4043 filler and did one of the butt welds with a V groove on both sides and the other one with no V grooves. I welded both sides of each V groove and seemed like the one with the V grooves welded a lot better. From what I’ve read, the frequency should be between 60 and 150hz so I chose 85 hz. And the balance should be around 25 to 30 so I chose 27. Not sure if those were good choices though. I just don’t have any experience with welding aluminum so it’s a bit of a learning curve.
The metal is cooked bro.
You should add some helium into your argon. You can use less amps and the welds come out much better.
Try some hobart 4943. Great stuff.
I'll check that out!!!

The bungs are 6061 T6 and I’m using 4043 filler.
Thanks for the comment and thanks for watching. I appreciate your time!!

I have experience welding various types of steel but aluminum is fairly new to me
