Main Features

1) Deposits are extraordinarily resistant to corrosion, cavitation, erosion, and metal - metal wearing, mainly in the presence of sea water.
2) High mechanical resistance.
3) Quick melting electrode for fast welding of dense, smooth and poreless weld beads.
4) Very easy to use.

Aplications

ARGENTA 812 has been specially formulated for aluminum brass welding of the Cu-Al, Cu-Al-Mn, Cu-Al-Ni alloy family and similar. Typical examples are welding and reloading of shipping propellers and shaft propellers, Welding and building of turbine engines. For reloading of carbon steel parts, weakly alloyed and stainless steels, Cu alloys. Restoring of coupling bearings for laminating rolls.

Well recommended for the reparation of body pumps under wearing caused by turbulent and saline fluids (cavitation).
