Application
Corrosion-resistant welding wire of grade ER385 is manufactured according to RD 03−613−03, GOST 2246−70, and technical conditions 1220 -005−84, 823 540−2010. This wire is applied for welding of constructions made of different high-strength, low-alloyed and carbon alloyed steels. This wire is also utilized for edge-banding of steel goods in compound with austenitic steels. Welding of the most critical structures is performed with a help of austenitic steels of grades: 30ChGSN2A, 30ChGSA. It can also be performed with alloyed and low-alloyed steels without heat treatment in quenched state and their combination with low-alloyed steels. Wire is used for deposit welding (welding) and manufacture of different grades of electrodes (OK 63.30 and OK 67.62).
Supply
It is delivered in bobbins (85−100 kg), wire-frame metallic coils K415, K300, plastic coils D200, 300. Available diameter of wire: 1 mm; 1,2; 1,6 mm; 2; 2,5 mm; 3, 4, 5 mm (we can make a required diameter to order).

Welding and technical characteristics
Welding wire for deposit welding of metal is used in argon environment (inert gas) in order to increase a quality of formation of filling, root, facing seam layers and to regulate arc burning. Welding is performed with welding flux (OK Flux 10.93 and its analogues).
