AWS A5.20 / ASME SFA5.20 E71T-5M-J
JIS Z3313 T49 4 T5-1 M A-U H5
EN ISO 17632-A-T 42 4 B M 3 H5
Applications
Mild and 490MPa high tensile strength steels for shipbuilding, machinery structures, bridges and
heavy plant facilities.
Characteristics on Usage
AWS A5.20 / ASME SFA5.20 E71T-5M-J Flux Cored Welding Wire is a basic type flux cored wire with excellent characteristics and is suitable for steel with tensile strength up to 600MPa.
Deposited metal shows superior crack resistance,excellent toughness at low temperature of -20~-50°C(-4~-58°F).
Welding Position Current Shielding Gas
DC + Ar+20~25%CO₂
Notes on Usage
① Proper preheating(50~150°C)(122~302°F) and interpass temperature must be used in order to release hydrogen which may cause cracking in weld metal when electrodes are used for medium and heavy plates.
② Use Ar+20~25% CO₂gas for welding.
