| Application and Properties: |
|
Heavy coated basic type
electrode producing tough and crack-free welded joints.
Suitable to use in welding fine grained structural
steels. Weld deposit is of extremely high metallurgical
purity and very low hydrogen content. Due to it's crack
resistance even under difficult operating conditions
such as dynamic loads, high and low environmental
temperatures, it is suitable for use in steel
constructions, pressure vessels, tanks, boiler and
special fabrications and in their root pass applications
with safely. 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. |
