Penzaelektrod expands the range: electrodes of the UONI 13/55 and UONI 13/55 series are on sale.

Welding electrodes of the UONI 13/55 and UONI 13/55 series from the Penzaelektrod manufacturer are designed for manual arc welding (MMA) of particularly critical structures made of carbon and low-alloy steels in all spatial positions except vertical from top to bottom. They provide a high-quality weld with high mechanical properties, which guarantees the reliability and durability of structures even at operating temperatures below -60 °C.

Features

• Low content of diffusively mobile hydrogen, sulfur and phosphorus with optimal content of alloying components.
• The rods are made of an alloy of iron, nickel, chromium and magnesium.
• The end of the electrode has a graphite tip, which improves the initial ignition.
• Gorenje rod is accompanied by a stable arc, which does not change with increasing or decreasing current.
• The slag follows the bath and hardens quickly. When cooling, it looks like dark glass and easily separates from the cooled metal.
• It is possible to work at sub-zero temperatures, which does not affect the quality of the seam.
• The electrodes are sensitive to the cleanliness of the surfaces to be welded. Before welding, the parts must be thoroughly cleaned to avoid sticking of the rod.
• They should be stored in a dry place. Immediately before welding, it is advisable to perform calcination in a special furnace at a temperature of 350-380 ° C for 1-1.5 hours.
• Welding electrodes UONI 13/55 and UONI 13/55 fully comply with the requirements of GOST 9467 75 and GOST 9466 75.

Scope of application

The electrodes UONI 13/55 and UONI 13/55 are designed for welding any structures made of carbon, low-alloy structural steel. They are in demand in shipbuilding, the oil industry and mechanical engineering. They are suitable for welding thick metal, which will be subjected to strong deforming loads.
