5、tional foreword This document (EN ISO 9013:2017) has been prepared by Technical Committee ISO/TC 44 “Welding and allied processes” in collaboration with Technical Committee CEN/TC 121 “Welding and allied processes” (Secretariat: DIN, Germany). The responsible German body involved in its preparation

6、was DIN-Normenausschuss Schweien und verwandte Verfahren (DIN Standards Committee Welding and Allied Processes), Working Group NA 092-00-07 AA “Equipment for gas welding, cutting and allied processes“. The DIN Standards corresponding to the International Standards referred to in this document are as

8、lasma cuts has been extended from 0,5 mm to 150 mm; b) the scope for laser cuts has been extended from 0,5 mm to 32 mm; c) the definitions for “cutting”, “cut” and “cutting speed” have been revised; d) a definition for “start of cut” has been included; e) the figure for form and location tolerances

9、of a sheet plate has been revised; f) 6.2.3 “Procedure” has been rendered more precise; g) Tables 6 and 7 have been extended by two columns for dimensions of 4 000 mm to 3 6 0,36 10 0,610 20 120 40 1,540 100 2100 150 3150 200 5200 250 8250 300 10The characteristic value of the mean height of the pro

10、file, Rz5, shall be determined within a limited area of the cut surface and the mean height of the profile, Rz5, shall be measured at 15 mm from the start of the cut in the advance direction. The measurement shall be carried out at the point of the maximum surface roughness of the cut surface, accor

11、ding to ISO 4288, using a device as described in ISO 3274.6.2.3 ProcedureThe characteristic values for the cut surfaces will be determined, according to the type of measurement, by means of the corresponding instruments listed in Tables 1 and 2.The mean height of the profile, Rz5, shall be measured

12、at 15 mm from the cut length in the advance direction. The measurement will take place in accordance with ISO 4288 using a tester as described in ISO 3274.If a measuring wire or sensor for coarse measurement of the perpendicularity or angularity tolerance cannot be introduced in the gap between shif

In the case of molten edges with unfinished projection, the latter will be considered in the perpendicularity or angularity tolerance.For cut thicknesses below 2 mm, the measur

14、ing procedure to determine the perpendicularity or angularity tolerance specifically has to be agreed upon.For cut thicknesses below 2 mm, the measurement of Rz5 is carried out at a distance of 1/2 of the cut thickness from the upper cut edge.With regard to all thermal cutting processes, the piercin

15、g area and/or the start section of a cut will be excluded from the measurements. The same applies to the end of the cut.7 Quality of the cut surface7.1 Characteristic valuesThe quality of the cut surfaces of thermally cut materials is described by the following characteristic values:a) perpendicular

16、ity or angularity tolerance, u;b) mean height of the profile, Rz5.The following characteristic values may be used in addition: drag, n; melting of top edge, r; possibly occurrence of dross or melting drops on the lower edge of the cut.7.2 Measuring ranges7.2.1 GeneralFor quality, the ranges for perp

17、endicularity or angularity tolerance, u, and mean height of the profile, Rz5, shall be indicated in the order u, Rz5. Where no value is fixed, a “0” (zero) shall be indicated.Isolated faults, such as gouges, the unavoidable formation of melting beads on the lower edge of the cut at the start of cuts

18、, or oxide remainders on the cut surface have not been considered when defining the quality values of this document.At multi flank cuts, e.g. for Y, double V or double HV seams (see ISO 2553), each cut surface shall be evaluated separately.7.2.2 Perpendicularity or angularity tolerance, uThe ranges

The limit deviations specified in Tables 6

24、and 7 shall apply to dimensions without tolerance indications, where reference is made to this document on drawings or in other documents (e.g. delivery conditions).They are only applicable to flame cuts and plasma cuts on work pieces with a length-to-width ratio (length : width) not exceeding 4:1 a

25、nd for lengths of cut (circumference) of not less than 350 mm.For work pieces cut by flame and plasma cutting with a length-to-width ratio greater than 4:1, the limit deviations shall be specified by the manufacturer following the principles set out in this document.For laser cutting, the maintainab

26、le dimensional tolerances depend essentially on the length-to-width ratio, the geometry and the pre-treatment conditions of the work piece.The given classes do not apply to the start and end of the cut and can only be achieved with serviced machines and trained operators.Material grade and the sheet

27、 temperature in comparison to the machine temperature needs to be suitable to meet the requirements of the allowed material elongation or contraction, e.g. due to the relief of residual stresses and thermal elongation during cutting.If necessary, the limit deviations may be agreed upon separately.Th

28、e limit deviations for the cut surface quality (perpendicularity or angularity tolerance) are treated separately from the limit deviations for the dimensional deviations of the work piece in order to emphasize the different influences on the work piece.NOTE The limit deviations do not include the de

29、viations from perpendicularity or angularity. As the definitions for the limit deviations are based on the independence principle, it was deemed not to be necessary to explain this fact once again by the additional indication of the tolerance according to ISO 8015 on the drawing. This avoids any mis

30、understandings with regard to a possible elimination of the independence principle if there is no reference to ISO 8015.If other form and location tolerances, e.g. straightness tolerance, perpendicularity tolerance in cut length and cut width direction, shall be maintained, they have to be agreed up

The

37、 nominal dimension of the part to be cut results from the assembly dimension (= drawing dimension), reduced by the limit deviation (see Figure 14). The real dimension of a component produced by a thermal cutting process always corresponds to the greatest dimension at outside dimensions and to the sm

38、allest dimension at inside dimensions.This kind of tolerance is normally required at welding joint preparation, as the work piece has to fit into an assembly.KeyA assembly dimensionB nominal dimension of the cut partGoupper limit deviationGulower limit deviationu perpendicularity or angularity toler
