TIG-680 | Dissimilar High-Strength Steel Buffer-Layer Welding Wire
TIG-680 โ Dissimilar High-Strength Steel Buffer-Layer Welding Wire
Suitable for joining high-alloy steel, spring steel, tool steel, and mold steel. It can also be used as a crack-resistant buffer layer beneath wear-resistant hardfacing deposits.
Typical hardness: HRC 25 - 28
Recommended processes: TIG welding and laser welding
Alloy / standard reference: Final alloy system shall be confirmed by the order and the corresponding batch material certificate.
Key Features
- Suitable for joining dissimilar and high-strength steels
- Provides a tough, crack-resistant buffer layer
- Supports precision joining, local repair, and surface restoration
- Final selection should be confirmed according to the base material, welding process, and service conditions
Typical Applications
- Tool steel
- Spring steel
- Mold steel
- Buffer layers beneath hardfacing deposits
Application guidance: Before welding, confirm the base-material grades, type of damage, heat-treatment condition, and subsequent machining requirements. Validate the final welding procedure on a test piece.
The information above is provided as a typical selection reference. Final supply condition, hardness, chemical composition, and welding procedure shall be confirmed by the order and the corresponding batch material certificate.
