CLASSIFICATION
AWS/SFA 5.29: E81T1-A1C,
ASME – IIC/SFA-5.29-E 81T1-A1M
DESCRIPTION
Tubular rutile flux-cored wire for single or multipass welding of 0.50 Mo heat resistant steels used for steam pipes of boilers of thermal power plant and similar types of steels, with CO2 shielding gas. The good weldability in all positions, excellent bead appearance, less spatter, a fast freezing and easy to remove slag. Deposited welds arc of radiographic quality.
