AWS A5.20 / ASME SFA5.20 E70T-1C/-9C

JIS Z3313 T49 3 T15-0 C A H10

EN ISO 17632-A-T 42 2 R C 3

Applications

welding of building, shipbuilding, bridge construction, machinery, vehicle using mild and 490MPa class high tensile steels.

Characteristics on Usage

AWS A5.20 / ASME SFA5.20 E70T-1C/-9C is a flux cored wire for Flat & H-fillet efficient welding with CO₂shielding gas.
As deposition rate is very high, highly efficient welding can be performed.Weld metal has good impact properties at -30°C (-22°F).Slag is uniform and easy to remove.

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 Use 100% CO₂gas.
