Hello, I've been having issues welding a small 1" OD (wall 0.085") Ai. bung onto a 2.5" OD (wall 0.075") Ai. pipe. I cannot get the two pieces of alumimum to puddle together. I can get puddles on either pieces, but I cannot get them to merge. I cleaned both pieces thoroughly. Stainless Steel brush and acetone wipe.
Here are my details:
Everlast PowerTig 185
CK TL 26 Flex with SuperFlex line
3/32 2% Lanthanated Tungsten, sharpened to a fine point
1/16 and 3/32 4043 Filler
100% Argon - 2 Bottles
12-20CFH Tried a few different flow rates
#8 pink cup
Stubby Gas lens kit from CK
SSC Controls Foot Pedal
Eastwood Welding Table
Here are my machine settings:
Set to AC and High Freq. Start and connected to 230v
Amps set to 100A currently. Have adjust to 80A and all the way to max 185A. Have foot pedal.
Frequency set at about 120hz to 200hz.
A/C Balance set at 50%. Have adjusted plenty either way
1/4" stickout up to half inch. Cup gets in the way
Sharpened tungsten 1/16" away from root.
The machine starts at 20A, I can see the cleaning action going but its tiny. So I give it more pedal, at around 50A the Ai starts to puddle on one side or the other, but never at the same time and never right at the root, If I point the tungsten to the other piece, the current puddle cools. I cannot get both pieces to puddle at the same time to join them with filler. I can get a blob of filler on each side and then get them to merge that way.
