Mig Welding Carbon Steel 11ga thick lap joint uphill high inductance

scroll down for detailed settings

If your mig welder has an inductance setting, setting it very high can help with very low wire speeds to slow things down and still maintain a smooth arc.

For 11ga steel, normally downhill would be used because uphill would tent to crown up excessively.

with a high inductance along with a very low wire speed, uphill was no problem.

WELD PROCESS = GMAW, SHORT CIRCUIT MIG, GAS METAL ARC, BARE WIRE MIG

METAL TYPE = CARBON STEEL, COLD ROLLED STEEL, AISI 1010

THICKNESS = 11ga

WELD TYPE = Fillet weld

JOINT TYPE = lap joint

POSITION = 3f vertical uphill

VOLTS = 19.5 volts

WIRE SPEED = 190 IPM

WIRE SIZE = .035"

POLARITY = DCEP

GAS FLOW = 20-25 CFH C25 GAS

CTWD  = 3/8”-1/2"

FILLER METAL = ER70S6

ADDITIONAL SETTINGS = inductance set to maximum

TIPS:A relatively short stickout aka contact to work distance CTWD of 3/8” to 1/2" makes a big difference.The technique shown is simple series of triangle shapes that traces the leading edge of the puddle
