GAS SHIELDED FLUX CORED WIRE
TM - 811N3 offers excellent arc stability and low spatter using CO2.
These weldability features, combined with low diffusible hydrogen levels and good impact values, make the TM - 811N3 a superior choice for shipbuilding, offshore drilling rigs, HSLA steels, and weathering steels where color match is not required. The wire is recommended for single and multiple pass welding in all positions using CO2.
Product Characteristics:
• Superior welding characteristics in all positions.
• 2% nickel weld metal promotes good CVN* impact properties. *Charpy V-Notch test or toughness test.
• Can be used with 100% CO2
• Capable of being used to weld several HSLA* steels.
*(HSLA steels are also more resistant to rust than most carbon steels because of their lack of pearlite – the fine layers of ferrite (almost pure iron) and cementite in pearlite [citation needed] HSLA steels usually have densities of around 7800 kg/m3).

Weld Test Parameters:
TM-811N3 .052” diameter electrode was welded using 100% CO2shielding gas with flow rate of 40 cfh, 200 amps (251 IPM), DCEP, and 25 volts with 3/4” electrical stickout and 250 deg ± 25 deg F interpass temperature. A total of five layers were welded, two passes each for Layers 2 through 5, one pass on Layer 1. The direction of travel was reversed for each layer.
