2222 M Stick electrode Ø 4.0mm

2222 M

The basic coated stick electrode produces a Ni-based weld metal that is resistant to cracking and corrosion. No risk of embrittlement due to the formation of σ phases, carbides or nitrides.
Residual welding stresses are reduced by plastic deformation. High ductility. Good gap bridging properties, good suitability for root welding.
Insensitive to long-term temperature stresses and heat treatments. Scale resistant.

1.4922 - X 20 CrMoV 12-1,
1.4935 - X 20 CrMoWV 12-1,
1.4961 - X 8 CrNiNb 16-13,
1.4981 - X 8 CrNiMoNb 16-16
1.4961 - X 8 CrNiMoNb 16-13,
2.4816 - NiCr 15 Fe,
2.4858 - NiCr 21 Mo

as well as corrosion-resistant steels, e.g:

1.7380 - 10 CrMo 9-10.
Also for buffering and corrosion-resistant coating of steel and iron materials.

Processing instructions
Remove cracked and otherwise damaged material. Clean welding areas. Re-dry at 350 °C / 2 h. During welding, adjust the heat to the component, its material and dimensions. Use line bead technique with low line energy. For workpieces with shrinkage
workpieces, first alloy the flanks.

Welding positions: all, except PG (f)
Type of current: = (+)
