Typically, I would prefer a 1/16" (1.6mm) electrode and filler for this test but I decided to experiment and used 3/32" for this video.
Root pass penetration seemed much smoother with 1/16" filler
After sending hundreds of these tests for X ray testing, the best results seemed to come from simply doing these steps
Fixtures like the Abom79 fixture used for this weld are common in the aerospace industry.
The hold down chill bars on the Abom fixture are adjustable and that is a good thing because different metals respond better to different rates of chill.
The closer the chill bars, the more rapid the chill factor.
Since aluminum is already highly conductive...less chill factor helps with x ray results.
too rapid chill factor often results in more porosity
slightly slower than normal travel speed and less chill factor allows a bit of time for contaminants to outgas before the puddle solidifies.
I recently added these kits to my store at weldmonger.com
These TIG Pro kits have cups for just about every situation.
Genuine CK Worldwide and Furick parts.
CK Worldwide / Furick Cup Genuine parts
What Comes in this kit?
You'll be getting genuine parts from two of my favorite American manufacturers:
With all the most popular Furick Cups, along with high quality CK worldwide gas lens cups…
let me just say that this kit has you covered for practically every possible Tig welding situation.
Need to walk the cup on sanitary stainless tubing? Large diameter CK gas lens cups are great for that.
Make some cluster welds on 4130 chromoly tubing with a 1” stickout? A Furick Ceramic Fupa 12 or Jazzy 10
is perfect for that.
Outside corner on 3/16” 3003 aluminum tread plate? Standard #5 cup, #8 Furick pro, or #6 CK gas lens works great for that
Exhaust collector on inconel 625? Jazzy 10 ceramic might be a great choice
Titanium pie cuts? A Furick BBW rules for that.
Anything from a standard #5 cup for thin aluminum to large gas lens cups for walking the cup on pipe, …
This kit has you covered.
A super convenient way to have every cup for every situation all in one TIG Pro Tackle box.
