Fixing Stainless Steel Heat Tint and Discoloration
Stainless steel discoloration and heat tint occur from oxidation during welding when insufficient shielding gas protection allows atmospheric contamination. Prevention requires proper backing gas, controlled heat input, and complete gas coverage.
Prevention Steps
- Use backing gas protection. Apply argon or forming gas to the root side to prevent oxidation.
- Control heat input. Lower amperage and faster travel to minimize time at elevated temperatures.
- Ensure complete coverage. Adequate torch gas flow and proper technique to protect heated areas.
- Use trailing gas. Extended gas coverage during cooling prevents late oxidation.

FORMIER® + CRONIGON® 2
Complete ProtectionWhy this combination works: FORMIER provides excellent root protection while CRONIGON 2 gives optimal face side shielding, eliminating heat tint and maintaining corrosion resistance.
