Impact energy (ISO-V) (J)
Electrode for welding dublex (ferritic-austenitic) stainless Cr-Ni-Mo steels. Especially used in welding of acid tanks and pipes, in chemical, petrochemical, paper, shipbuilding and desalination industries. Suitable also for welding dublex stainless steels to carbon steels. The delta-ferrite content of the as-deposited weld metal amounts to approx. 25 to 35 %. The high-strength and ductile weld metal exhibits good resistance to pitting, crevice corrosion and stress corrosion cracking in chloride-bearing media. For operating Temperatures of up to +250°C. Possible to use equally well both with AC and DC. Fine metal droplet transfer, good fusion of joint faces, finely rippled bead surface, easy arc striking, restriking and slag removal.

Impact energy (ISO-V) (J)
Electrode with special covering for welding aluminum-silicium alloys and for joining dissimilar aluminium alloys. Used with DCEP. In welding, hold electrode perpendicularly to workpiece, with a short arc. Wall thickness greater than 10 mm and larger workpieces will require preheating from 150°C to 250°C. Since slag residues are corrosive, they must be completely removed from the weld bead. Electrode serves well as consumable in oxyacetylene welding. The covering being hygroscopic, electrodes must be stored in an absolutely dry location, or redried if required.

Electrode with special covering for welding aluminium-silicium cast alloys. In welding, hold electrode perpendicularly to workpiece, with a short arc. Wall thickness greater than 10 mm and larger workpieces will require preheating from 150°C to 250°C. Since slag residues are corrosive, they must be completely removed from the weld bead.
