A very common mistake beginners make when learning to TIG weld aluminum is to add filler rod before the puddle is ready.
This short video shows the difference in cleaning action from the arc...
and the actual molten aluminum puddle.
When you are learning how to tig weld aluminum, one mistake beginners often make is to add rod too early...before the aluminum is formed.
WELD PROCESS = TIG, GTAW, GAS TUNGSTEN ARC WELDING
METAL TYPE = ALUMINUM 6061
THICKNESS = .063"
WELD TYPE = BEAD ON PLATE TO DEMONSTRATE DIFFERENCE BETWEEN CLEANING ACTION AND ACTUAL PUDDLE
JOINT TYPE = BEAD ON PLATE
POSITION = FLAT
AMPERAGE = 60-70 AMPS
TUNGSTEN = 2% LANTHANATED, 3/32" FILLER WIRE = 1/16” 4043
POLARITY = AC
GAS FLOW = 15-20 CFH argon
CUP SIZE = 8
ADDITIONAL SETTINGS = AC BALANCE 35% CLEANING, AC FREQ 110HZ
PRE FLOW = 1 SEC
POST FLOW = 10 SEC
TIPS: A COMMON MISTAKE FOR BEGINNERS IS TO ADD ROD BEFORE THE PUDDLE IS READY.
WAIT TO SEE THE SHINY WET AREA BEFORE ADDING ROD.
KEEP A FAIRLY TIGHT ARC AND WATCH TORCH ANGLE
Aim for an arc length that is equal or less than the diameter of your tungsten electrode. Torch angle can be forgiving provided your arc length is tight.
