MIG CARBON STEEL 1/4” THICK UPHILL 5F TUBE PLATE

scroll down for settings

A 5F weld test is sometimes used to qualify a welder for all positions but only for fillet welds.

Usually some cross section macro etch testing is done to check for adequate penetration into the root of the joint

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

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

THICKNESS = 1/4” .250, 6mm

WELD TYPE = Fillet weld

JOINT TYPE = tee joint

POSITION = 5f vertical uphill

VOLTS = 17.7 volts

WIRE SPEED = 289 IPM

WIRE SIZE = .035"

POLARITY = DCEP

GAS FLOW = 20-25 CFH C25 GAS

CTWD  = 3/8”-1/2"

FILLER METAL = ER70S6

ADDITIONAL SETTINGS = 

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 V shapes that traces the front leading edge of the puddle
