If you are searching for a procedures for socket welds, I hope this page helps.

While we don't have official welding procedures for socket welds here, this page should help you get started in writing your own procedure for socket welds.

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

TUNGSTEN = 2% LANTHANATED, 3/32"

FILLER WIRE = 3/32” ER70S2

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
