AWS A5.20 / ASME SFA5.20 E71T-1C/-9C

JIS Z3313 T49 3 T1-1 C A-U H5
EN ISO 17632-A-T 42 2 P C 1 H5

Applications

All position welding of building, shipbuilding, bridge construction machinery, and vehicles

Characteristics on Usage

AWS A5.20 / ASME SFA5.20 E71T-1C/-9C Flux Cored Welding Wire is titania type flux cored wire for all position welding. It has extra low hydrogen levels(H5) and provide an exceptionally smooth and stable arc with a fast freezing slag system.

Welding Position                                   Current                          Shielding Gas

DC +                                                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 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 Use 100% CO₂gas.
