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-position welding including vertical downward 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:

1. In order to get enough penetration in the vertical downward 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.

2. Use CO² gas equivalent to JIS K 1106 Gr-3 or CO² gas purified for shielding in welding.

3. It is very important to control mixture ratio when mixture gas of Ar + CO² is used because the fluctuation of mixture ratio may effect adversely on usability.

4. It is suitable to use shielding gas of 20 to 25 I/min.
