CLASSIFICATIONS: E81T1-A1C, E81T1-A1M per AWS A5.29, ASME SFA 5.29

A low alloy steel electrode for flux cored arc welding, Select 810-A1 is intended for single and multiple pass welding, in all positions, of certain carbon-molybdenum steels where the addition of 1/2% molybdenum is required in the deposited weld metal.

APPLICATIONS: Select 810-A1 is ideally suited for welding certain C-Mo steels used in the fabrication of boilers and pressure vessels such as ASTM A161, A204 and A302 Gr. A plate and A335-P1 pipe.

DIAMETERS: .035", .045", .052", 1/16"

SHIELDING GAS: 100% CO2, 75% Ar/25% CO2
, 35-50 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Quick freezing slag facilitates all position welding.
  • Excellent fluxing action.
  • Increased productivity – up to 3 times the deposition rate of covered electrodes – up to 2 times that of solid wire.
