Just like we did with Carbon Steel. This video covers some good tips on how to build muscle memory without filler metal before you do the real thing.
Aluminum will often crack when welded without filler metal but dont be too concerned about that right now....this is a learning exercise before progressing to adding filler metal.
Its also a good practice to use 2 separate plates so that one of them can be cooling off while you practice on the other.
.125" 3.2MM THICK aluminum
3/32" 2% lanthanated electrode
#6 cup with 12-15 cfh argon gas
It's time to take what we learned from EP09 and lay down some beads with filler metal on Aluminum.
11ga thickness is used in the video so amperage was around 120-140
We've covered how to TIG Weld Aluminum, so let's look at some things to avoid when TIG Welding. If you're the kind of person, who doesn't like to see things done the wrong way, just skip this one!
Build your skills with "The Aluminum Drill" laying lots of beads and learning from your progress/mistakes.
This is one of the very best skill drills you can do to improve your overall TIG welding skills.
