PREMIUM MIG WIRES FOR WELDING AT THE EDGE OF STEEL
CARBOFIL TENSIMAX SERIES FOR EXTREME WELD STRENGTH
When performance reaches the limits of modern steel design, you need a filler metal engineered to go further.
CARBOFIL TENSIMAX is a premium MIG wire family developed for high- and ultra-high-strength steels in the 690-1300 MPa range, including grades such as S690QL, S770QL, S1100QL and S1300QL.
It delivers stable arc performance, controlled weld-metal behavior, and reliable mechanical properties required for demanding high-strength steel applications.
Meet CARBOFIL TENSIMAX - our next‑generation MIG wire range for the most demanding high‑strength steel applications.
Challenges in Welding High‑ and Ultra‑High‑Strength Steels
Even when strength classes align, real weld properties depend on how filler metal, base material, and heat input interact - a relationship far more complex than chemical matching alone.
High‑strength steels react sharply to slight variations in:
- heat input
- cooling rate
- welding parameters
Even small deviations can shift the weld microstructure, causing significant changes in toughness and strength.
These steels undergo major structural changes during heating and cooling. If the filler metal is not precisely engineered for this thermal cycle, weld integrity can suffer, especially in demanding or safety‑critical applications.
A filler wire may match the nominal strength class but still fail to deliver equivalent weld‑metal properties. True compatibility is metallurgical, not declarative.
Ideal test setups cannot replicate the variability of shop‑floor welding. The filler metal must consistently deliver required performance under actual working conditions, not just in controlled laboratory environments.
As steel strength increases, the metallurgical relationships between material, filler metal, and welding heat become more critical, and the acceptable tolerance window becomes significantly tighter.
