Applications

All position welding of shipbuilding, bridges, building and structural fabrication.

Characteristics on Usage

AWS A5.20 / ASME SFA5.20 E71T-1C/-9C/-9C-J Flux Cored Welding Wire is a titania flux cored wire for all position welding with high amperage. Its impact value is very good under high heat-input, arc is smooth and slag detachability is excellent .

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.
