MESSER SOLUTION
As a rule, so-called forming gases, nitrogen/hydrogen mixtures, are used. The hydrogen component provides more security against residual oxygen. High-quality forming, however, requires only very low hydrogen content.
Advantages:
- Protects the root side
- No reaction of the melt with air components
- No changes in colour or slag on the root side
- Better corrosion resistance for CrNi-steels and nickel alloys
