Ten advantages of the GW®-HPS-Technology compared to state of the art

Only one welding pass applied, thus reducing the source of defects through binding problems between the layers or inclusion of slag.

The layer is completely homogeneous due to the extreme perfect mixing of base material and additional supplied alloyed powder.

Equal hardness within the complete wear-resistant coating.

Equal and homogeneous chemical composition of the complete layer.

Built-up thickness can be used without any restrictions.

Layer thickness up to 11mm on radius is possible with one welding pass.

Perfect longlasting lifetimes, due to homogenous structure only minimum depth of fire cracks and therfore only minimum cut for overhaul is necessary.

Flexible use of different base materials for rolls.

Highest flexibility regarding the chemical composition of the wear resistant layer. Taylor made chemical compositions of welding layer can be achieved by simply adjusting cored wire and alloying powder.

Due to the cooling effect through the alloying metal powder the increase of temperature while welding is only minimal, which allows increased layer thickness with equal hardness.
