WIRES FLUX CORED
KOBE FLUX CORED WIRE DW-100
For gas-shielded metal arc welding of mild steel and 50kgf/mm 2 high tensile steel.
Classification
JIS Z3313 YFW C50DR
AWS A5.20 E71T-1
Applications
Butt or fillet MAG welding of structures such as ships, bridges, buildings, or storage tanks, etc.
Characteristics on Usage
DW-100 is a titania type flux cored wire applicable for all positioning welding including vertical downwards by CO2 gas shielding. It provides excellent usability with soft and
stable arc, less spattering, better bead appearance, better slag removal, and less quantity of welding fume as the same as that of a solid wire. DW-100 provides very efficient
welding due to higher deposition rate particularly.

Notes on usage
In order to get enough penetration in the vertical downwards welding, maintain a little bit higher welding speed by straight manipulation for the first pass. Take the straight
manipulation on succeeding passes too as much as possible.

Applications
MAG welding of a dissimilar joint consisting of a stainless steel and a carbon steel or a low alloy steel. Under-layer welding on cladded side groove of cladded stainless steel, or
on a carbon steel or a low alloy steel where stainless steel weld metal is overlayed.
Characteristics on Usage
DW-309, DW-309L and DW-309MoL are flux cored wires whose weld metals contain comparatively much more ferrite in their austenitic structures, therefore, they provide
better weldability together with superior heat resistance and corrosion resistance. As larger amounts of alloying elements are added, they are suitable for dissimilar joints where
dilution from a ferritic steel takes place.
