Application Area. OZR-1 Welding Electrodes.

OZR-1 metal cutting electrodes are intended for: – cutting, gouging, piercing of holes; – removal of defective areas of welded joints and castings, edge preparation and root pass removal; – performing other similar works during fabrication, installation and repair of parts and structures made of steels of all grades (including high-alloy), cast iron, copper and aluminum, and their alloys.

Welding Technique. OZR-1 Welding Electrodes.

Cutting is performed at increased parameters with the electrode tilted in the direction opposite to the cutting direction (forehand angle). The electrode must perform reciprocating movements: “back and forth” or “up and down”.

When piercing holes, the electrode is positioned perpendicular to the surface of the part with pressure. The position of the part being cut should ensure free drainage of molten metal downward.

Main Weldable Materials. OZR-1 Welding Electrodes.

Cutting, gouging, piercing of holes, removal of defects in welded joints and castings, edge preparation on steels (including high-alloy), cast iron, copper, aluminum and their alloys.

Special Properties. OZR-1 Welding Electrodes.

OZR-1 electrodes provide a clean cut without burrs, flash or drips of molten metal on the surface. Due to the special coating, they have very high heat resistance, allowing for a powerful and stable arc at increased currents. They create strong pressure on the molten metal, ensuring rapid removal of melt from the cutting zone.

No special surface preparation of the part being cut is required. High productivity: cutting time for reinforcement with a diameter of 16 mm is 2–3 seconds, with a diameter of 40 mm — 14–16 seconds.
