Nertajet HP High Plasma - Air Liquide Welding

CPM 400-450NERTAJET 150/300/450In many industries, the cutting of ferrous and non-ferrousmetals is a major operation for which the requirementsfor quality, productivity, availability and efficiency ofinstallations have a significant effect on the businessperformance. Cut quality in this respect is a key elementthat determines the choice of production equipment.Major sectors of activity which cut metal sheets:boiler fabrication, shipbuilding, railroad, rolling stock,road vehicles, agriculture, agrifoods, ventilationand air conditioning, sheet metalwork, pattern cutting,street furniture, lamp posts…Main cuttingquality criteriaVarious characteristics can be evaluated to understand the cutting quality.EN standard ISO 9013 retains mainly three:- geometric accuracy- surface roughness- angle/concentricityThis last criteria determines, based on the thickness, the perpendicularitytolerance in five classifications (ranges 1-5).Regular kerfa = angle and concentricity2Tolerances of perpendicularity or angularityBurrsRz = roughnessGeometricprecisionWeldabilityAngleTolerance u, in mm1,510,500 5 10 15 20 25 30Cutting thickness in mm54321RANGE2
