Rutile flux-cored welding wire of type T 23 12 2 L / E309LMoT0 for GMAW of dissimilar joints of Cr- and CrNi(Mo)-
steels and non- or low-alloy steels, as well as weld cladding of un- or low alloyed base metals preferably in flat or horizontal
position. The wire offers a high safety against hot cracking even in the case of high dilution. For Mo-alloyed surfacing
the product is necessary for the 1. layer. This product achieves high productivity and is easy to operate achieving
excellent welding characteristics, self releasing slag, almost no spatter formation and temper discolouration,
smooth weld finish and safe penetration. Beside the major savings in time and cost BÖHLER offers a high production
quality level together with lowest probabilities for welding errors. Increased travel speeds as well as little demand for
cleaning and pickling provide considerable savings in time and money. Suitable for service temperatures of –60 °C to
+300 °C. BÖHLER CN 23/12 Mo-FD ø 0.9 mm is well suitable for welding of sheet metal (thickness greater than 1.5
to 3 mm, for out-of-position welding greater than 5 mm). The slag concept gives the opportunity to weld this diameter
in all welding positions. Wires with ø 1.2 mm can be used for wall thicknesses from 3 mm and up. Wire ø 0,9 mm is
designed for positional welding, wire ø 1.2 mm and 1.6 mm are recommended mainly for downhand and horizontal
welding positions, horizontal/vertical position as well as slightly vertical down position (1 o'clock).

Welding with standard GMAW-facilities possible, slightly trailing torch position
(angel appr. 80 °), when using 100 % CO2 as shielding gas it is necessary
to increase the voltage by 2 V. The gas flow should be 15-18 l/min.
