MIG WELDING CARBON STEEL HANDRAIL PIPE FITTING 3/16" THICKNESS

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

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

THICKNESS = 3/16”” 1-1/2” PIPE SCHED40

WELD TYPE = groove

JOINT TYPE =open butt

POSITION = 1G ROLL OUT

VOLTS = 18 volts

WIRE SPEED = 230 IPM

WIRE SIZE = .030"

POLARITY = DCEP

GAS FLOW = 20-25 CFH C25 GAS

CTWD = 3/8”-1/2"

FILLER METAL = ER70S6 .030"

ADDITIONAL SETTINGS =

TIPS: A TEST PIECE OF 1/4" PLATE BEVELED TO 30 DEG WAS USED TO VERIFY SETTINGS BEFORE WELDING PIPE AND FITTING

A relatively short stickout aka contact to work distance CTWD of 3/8” to 1/2" makes a big difference.

The technique shown is a very slight side to side motion while keeping the arc on the front edge of the puddle while not far enough to shoot wire thru the gap.
