 Print Sheet


CLASSIFICATION: E80C-B2 per AWS/ANSI A5.28, ASME SFA 5.28

A metal cored, low alloy steel electrode, Select 80C-B2 is designed for both single and multiple pass welding of certain chromium and molybdenum steels.

APPLICATIONS: Select 80C-B2 is intended to weld materials such as ASTM A335-11 pipe and A387 Grade 11 plate. The weld metal is designed to withstand the high temperature service of the base materials.

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

SHIELDING GAS: 75-95% Ar/balance CO2, 95-98% Ar/balance O2, 40-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Provides higher deposition rates and increased penetration.
  • Greater deposit weld consistency than solid wire.
  • Lower spatter and faster travel speeds mean reduced welding costs.
