CSM-550

For 520N/mm2 class high tensile strength steel


Applications	Butt, fillet welding of 520N/mm2 high tensile strength steels of structure such as ships, bridges, buildings and storage tanks etc.
Characteristics	(1) CSM-550 is a metal type flux cored wire for flat & horizontal fillet welding with CO2 gas shielding. (2) Its deposition rate is 10~30% higher compared with a solid wire, so total cost is saved. (3) It provides excellent usability with stable arc, less spattering better bead appearance and less quantity of welding fume comparable to solid wire.
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
