Composition of BÖHLER metal powders - Tenica

Flame spray weldingFlame spray welding is a surface coating process. From ashort distance, via a torch the metal powder is sprayed ontothe base material and simultaneously fused. This producesfusion between the sprayed layer and the base materialcomparable to welding.With flame spray welding, the surface of the workpiece hasto be cleaned thoroughly of rust, grease and oil. The rougheningof the metallically clean surface should be effected byblasting or rough grinding in order to facilitate a good bondof the sprayed layer. Spraying should immediately be carriedout after surface preparation.This method is suitable for applying thin layers to smallareas, edges and repair work. Low and high alloy steels,stainless steels, cast steels, malleable cast iron, flake andspheroidal graphite cast iron can be sprayed. Powder basedon with additions of Cr-Si-B and powder-mix qualities areavailable.Flame spray welding with BÖHLER metal powder Niborit 4-P.Schematic representation of the flame spray welding.Acetylene oxygen mixturePowder containerSpraying powderLever forpowder supplyNozzleFlameOxygenAcetyleneCoatingBase materialAdjust oxygen supplyAdjust acetylene supply10
