Welding Electrodes

Welding ElectrodesWelding electrodes with basic coating UONII-13/55, designed especially for welding important structures made of carbon and low-alloy steels, when the metal welds are increased requirements for ductility and toughness. Recommended in particular for welding structures operating at low temperatures (-40 ° C). Wire rod of CB-08, CB-08A according to GOST 2246-70. The diameter of electrodes produced 2.0, 2.5, 3.0, 4.0 and 5.0 mm.

 

The special properties of the electrodes UONI-13/55:

 

The weld metal has a high resistance against crack formation of crystallization and low hydrogen content. Welding should be done by a short arc bearing. Welded edges shall be free from mill scale, rust and oil.

 

The use of welding electrodes UONI-13/55:

 

Welding of critical metal working under dynamic loads in freezing conditions, the vessels working under pressure, shipbuilding steel. Welding of thick metal. Welding casting defects.

 

Technological features of welding electrodes UONI-13/55:

 

Produce short arc welding on the edges cleaned.

Calcination is required before welding: 150-180 C, 0.5 hours
