SPECIAL FEATURES

Electrodes ZN-6L provide a weld metal that is resistant to corrosion and erosion in the environment of water and steam, and is resistant to galling.

MELTING PROCESS FEATURES
Surfacing produce preheater to a temperature of 300-400 ° C. Surfacing of small-sized products may be unheated. The heat treatment of large-size products is carried out directly after deposition. Mandatory calcination process before welding: 120-150 ° C; 1 h.
