TIG Welder Settings for 1-1/2" socket weld

WELD PROCESS = TIG, GTAW, GAS TUNGSTEN ARC WELDING

METAL TYPE = CARBON STEEL

THICKNESS = WALL THICKNESS 1/4”

WELD TYPE = Fillet weld SOCKET WELD

JOINT TYPE = SOCKET WELD

POSITION = IN VISE 2F HORIZONTAL

AMPERAGE = 120 AMPS FOR ROOT, 133 FOR SECOND PASS

TUNGSTEN = 2% LANTHANATED, 3/32"

FILLER WIRE = 3/32” ER70S2 FOR ROOT 1/8" ER70S2 FOR SECOND PASS

POLARITY = DCEN

GAS FLOW = 20CFH argon

CUP SIZE = 8

ADDITIONAL SETTINGS = LIFT ARC

PRE FLOW = TORCH VALVE

POST FLOW = TORCH VALVE

TIPS: 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. Keep the hot tip of the filler wire shielded by the argon envelope from the tig cup

SNIP THE END OF WIRE EVERY RESTART

Socket welds are part of most pipe welding jobs on paper mills, power plants, and any other job where process and power piping is done. In this video I used a scratch start setup with a valve torch because that is commonly done on socket welds on the job site. I used 120 amps for the root pass with 3/32" er70s2 filler rod and 133 amps for the cover pass using 1/8" er70s2. a #8 cup with 20cfh argon along with 3/32" 2% lanth electrode and a TIG Finger XL.
