Characteristics
NC-309MoL is a lime-titania type electrode for all-position welding, which have good usability and good weldability. Good resistance against dilute sulfuric acid compared with that of VSS-309.
Weld metals provide excellent corrosion resistibility and heat resistibility in the as welded condition.
As VSS-309L-Mo is of low carbon content, it can be used for welding of extra-low carbon stainless steel which contains Mo and for under laying of mother plates which contain considerably high carbon content.
Notes on usage
(1) Keep the arc as short as possible and choose the welding current as low as possible.
(2) Weaving width should be within two and a half times of electrode’s diameter.
(3) When the electrodes have absorbed moisture, dry them at 250-300˚Cb for 60-90 minutes before use.
