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
