CLASSIFICATIONS: E80T1-B2C per AWS A5.29, ASME SFA 5.29
Select 81-B2 is a low alloy steel electrode for flux cored arc welding.
This electrode is designed for single and multiple pass welding
in the flat and horizontal positions of certain chromium-molybdenum
steel and pipe grades, where 1 1/4% Cr and 1/2% Mo are required
in the weld deposit.
APPLICATIONS: Select 81-B2 is an excellent selection to weld
steels subject to high temperature service such as ASTM A387, Gr.
11 plate and A335 P11 pipe. These materials are employed in the
fabrication of boilers, heat exchangers and pressure vessels.
DIAMETERS: 1/16", 5/64", 3/32"
SHIELDING GAS: 100% CO2, 35-50 cfh
WELDING POSITIONS: Flat and Horizontal
CHARACTERISTICS:
Promotes spray-like arc transfer with very low spatter.
Bead profile exhibits minimum of convexity.
Resists creep and maintains strength at elevated temperatures.
