Description
The welding consumable Böhler DCMS Ti-FD is a low alloyed, flux-cored wire with rutile filling,
primarily designed for the welding of 1 % Cr and 0,5 % Mo alloyed creep-resistant base metals,
that are used for the fabrication of vessels, high-pressure storage tanks and pipe systems.
Due to the fast freezing slag system this flux-cored wire provides excellent positional welding
characteristics and allows fast travel speeds to be used. This flux cored wire is for welding with
normal power sources on DCRP under Mixture gas (82 % Ar +18 % CO2).
