JIS Z3313 T49 3 T5-1 C A-U H5
EN ISO 17632-A-T 42 3 B C 2 H5

Applications

AWS A5.20 / ASME SFA5.20 E71T-5C Flux Cored Welding Wire is suitable for welding of mild and 490MPa high tensile strength steels for shipbuilding, machinery structures, bridge construction and heavy plant facilities.

Characteristics on Usage

AWS A5.20 / ASME SFA5.20 E71T-5C Flux Cored Welding Wire is a basic flux cored wire with excellent characteristics and is suitable for steel with a tensile strength up to 600MPa. Deposited metal shows superior crack resistance, excellentat low temperature at -20~-30°C(-4~-22°F).

Welding Position                                   Current                          Shielding Gas

DC +                                                   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 One-side welding defects such as hot cracking may occur with wrong welding parameter such as high welding speed.

③ Designed for use with DC(-).④ Use 100% CO₂gas.
