EnDOtec® DO*23 welding wire
Developed for assemblies or rebuilding on cast irons with Maximum Safety Margin. Joining cast iron to steel.
Gas shielded welding cored wire.
EnDOtec®’s composite cross sectional design automatically produces a higher current density in the electrode’s metallic periphery over solid MIG/MAG wires of the same diameter using the same welding amperage. This ensures over 30% faster electrode fusion without sacrificing weld quality giving record weld deposition rates over MIG/MAG and Manual Metal Arc processes. Thanks to EnDOtec®’s intrinsic higher current density, a cored wire can always be welded at lower amperages than a solid wire whilst keeping a stable metal transfer across the arc due to ionising elements in the core.
Lower heat input means that EnDOtec® welds have better bonding, lower dilution, superior microstructure properties and minimal heat affected zones for maximum service performance.

Features and benefits
- Tough nickel-iron matrix dispersed with fine spheroidal graphite.
- Low heat input reduces Heat Affected Zone.
- Preheating & Postheating normally not required.
- Highest resistance to hot & cold cracking.
- Dissimilar joining capability between cast irons & steel.
- Reduced residual stresses allow thick welds (~3cm).
- Slag free, machinable deposits.
- Rust resistant welds.
- Deposits can be chromium plated.
