Welding Electrode | Flux Cored | Low temperature Steel | Chosun Welding CSF-71S

Applications

• Butt, fillet welding of 490N/mm2 class high strength steel and low temperature steel of structure such as ships, bridges, buildings and storage tanks etc.

Characteristics

• (1) CSF-71S is a titania type flux cored wire and designed for all-position welding by single pass & multi pass with CO2 gas shielding.
• (2) It provides the excellent usability with stable arc, less spattering, good bead appearance, better slag removal, and less quantity of welding fume comparable to solid wire.
• (3) It provides a good welding efficiency thank to high deposition rate particularly.
• (4) Weld metal has good impact properties at -40℃.

Notes on usage

• (1) The optimum flow of CO2 for shielding is 20~25ℓ/min.
• (2) The distance between tip & base metal is to be 20~25mm.
• (3) Protect the weld with a screen to prevent blowholes caused by wind where the wind velocity is 2m/sec and more.
• (4) Thick heavy plate should be welded under proper preheating & interpass temperature.

Shielding Gas

• 100%CO2
