| Application and Properties: |
|
Electrode producing tough
and crack-free welded joints. Suitable to use in welding
low alloy high strength steels and fine grained
structural steels. Weld deposit 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, making it
well-suited for positional welding. Welds are of X-ray
quality. On request, electrodes may be furnished with
special quality assurance to KTA 1408.2. |
