TIG CARBON STEEL 11GA LAP JOINT AND RESTARTs

Making a good smooth restart is fundamental to tig welding as well as all other types of welding.

Lets face it, you are going to run out of rod, or need to sneeze, or whatever and you will need to make a restart.

And if you can make a restart where you can't even tell where you restarted, then you are freed up to weld the thing however you need to.

WELD PROCESS = TIG, GTAW, GAS TUNGSTEN ARC WELDING

METAL TYPE = CARBON STEEL

THICKNESS = 11GA

WELD TYPE = Fillet weld

JOINT TYPE = LAP JOINT

POSITION = 2f HORIZONTAL

AMPERAGE = MACHINE SET TO 100-125 AMPS CONTROLLED WITH PEDAL  115 AMPS SWEET SPOT

TUNGSTEN = 2% LANTHANATED, 3/32"

FILLER WIRE = 1/16” ER706

POLARITY = DCEN

GAS FLOW = 20 CFH argon

CUP SIZE =  8

ADDITIONAL SETTINGS =   

PRE FLOW = .5 SEC

POST FLOW = 7 SEC

TIPS: KEEP A TIGHT ARC ..practice restarts until they blend in

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
