Field of application

Corrosion-resistant welding wire of grade ER 308 LSi is used for semi-automatic welding of stainless steels (19−9) in shielding gasses and their mixture, for manual arc welding of critical constructions made of austenitic steels: X12CrNiTi18−10, X10CrNiTi18−9 and identical to them that operate at high temperatures of 570−650°C and pressure. ER 308 LSi is also applied for welding of analogous grades of steels if there are no severe requirements to intercrystalline corrosion resistance.

Cassette with a weight of 15−18 kg (K -300). Bobbin with a weight of 5 kg (D-200). It is delivered in bobbins (85−100 kg), wire-frame metallic coils K415, K300, plastic coils D200, 300. Standard diameter of wire: 0,8 mm; 1,2 mm; 1,6, 2 mm, 3 mm (we can make a required diameter to order).

Advantages of application

— permanent diameter over length of wire, high characteristics of welded seam, layers tight winding;

— qualitative wire guarantees a stability of current contact jaws (contact point — wire) and regulates an arc burning.

Technological characteristics of weld metal

Deposit welding of metal is performed in argon environment (inert gas). Formation quality of filling, root, and facing seam layers depend on stable arc burning.
