AA R500

Category 
type 
Seamless micro-alloy rutile flux-cored wire with rapidly solidifying slag for gas-shielded welding with mix-gas Ar-CO2 and CO2
applications 
Onshore and Offshore. Ship-, pressure vessel- , bridge-, pipeline and general steel construction. General engineering. Heavy transportation and rail construction, etc.
Properties 

Excellent modelling ability, therefore excellent forced position welding in all positions at high amperage. Down to -60 °C very good impact values are achieved. Particularly suitable for MAG orbital welding and for welding on ceramics in all positions. Low spatter losses, easily removable slag. CTOD tested to -20 °C Extremely low diffusible hydrogen content (on average below 3 ml / 100 g) in the weld metal. For the entire storage and processing time <4ml / 100g are guaranteed according to AWS.

redrying temperature 
No re-drying necessary due to the closed production of the filling tube. It is strongly discouraged because it can lead to high quality problems! Storage without special requirements, analogous to solid wire, taking into account strong temperature fluctuations and their effects (dew point) in original packaging then unlimited possible.
