| Application and Properties: |
|
Heavy coated basic type
electrode producing tough and crack-free welded joints.
Suitable for welding fine grained structural steels and
steels with yield strength up to 900 N/mm². Weld deposit
is of extremely high metallurgical purity and very low
hydrogen content. Due to it's double covering (up to 3,2
mm), the electrode features a stable and concentrated
arc, rendering it well-suited for positional welding.
Welds are of X-ray quality. |
