JIS Z3313 T49 4 T1-1 M A-U H5
EN ISO 17632-A T46 4 P M 1 H5

Applications

All postion welding of building, shipbuilding, bridge construction machinery, and vehicles.

Characteristics on Usage

① AWS A5.20 / ASME SFA5.20 E71T-9M-J Flux Cored Welding Wire is a titania type flux cored wire for all position welding.
② AWS A5.20 / ASME SFA5.20 E71T-9M-J Flux Cored Welding Wire It provides excellent notch toughness at low temperature.

③AWS A5.20 / ASME SFA5.20 E71T-9M-J Flux Cored Welding Wire It provides an exceptionally smooth and stable arc with a fast freezing slag system.

Welding Position                                   Current                          Shielding Gas

DC +                                              Ar + 20~25%CO₂

Notes on Usage

① Proper preheating 50~150℃(122~302℉) and interpass temperature must be used in order to release hydrogen which may cause cracking in weld metal when electoredes 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 Use Ar+20~25%CO₂gas.
