Schmelzschweißverbindungen an Stahl, Nickel, Titan und deren Legierungen ohne Strahlschweißen. However, the choice of an execution class does not necessarily have to be the same for all the requirements.

All copyright requests should be addressed to. Special provisions may be necessary for complex struc- tures. Please first before subscribing to alerts. This may be effected, for example, with the aid of optical devices, tubular water lev- els, span wires, floor plates, surface plates, and machine beds.Next
It is to be multi- plied by the length, in m, of the shorter leg. If smaller tolerances are needed or bigger ones are more economical, then these tolerances are indicated next to the nominal size. The quality levels refer to production quality and not to the fitness for purpose of the manufactured product. A comma is used as the decimal marker. Its principles can also be applied to partial-penetration butt welds. It is engineer responsibility to select the appropriate admissible level taking into account the importance of the welded piece and its destination.Next
Already Subscribed to this document. Standarden gælder for materialetykkelse over 0,5 mm. The applicable tolerances are always those which are stated in the drawing. The distances between the actual surface and the measur- ing plane shall be measured for example, see figure 7. This standard provides quality levels of imperfections in fusion-welded joints except for beam welding in all types of steel, nickel, titanium and their alloys. Tolerance class Z has been dropped. A structure can include several execution classes.Next
Fusion-welded joints in steel, nickel, titanium and their alloys beam welding excluded. They are applicable for all characteristics of the form elements accept cylinders, profiles of any line or surfaces, inclines, coaxiality, position and total movement.

For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.Next
Principperne i detnne standard kan også gælde for delvist gennemsvejste stumpsømme. Several types of loads are considered, e. In the following some considerations about the welding prescriptions are reported as per Eurocode norm. It applies to material thickness above 0,5 mm. If you have any questions or suggestions regarding the accessibility of this site, please.Next
You may delete a document from your Alert Profile at any time. This does not apply to temporary dimensions. By choosing a special tolerance class exactly the precision level common in workshops should be taken into account. Your Alert Profile lists the documents that will be monitored. The angular deviation may be measured in degrees and minutes, or in millimetres. A measuring plane shall be established parallel to the ref- erence plane and apart from the weldment, using the meas- uring devices referred to in 6.Next
This standard applies to manual, mechanized and automatic welding and for all welding positions. The quality levels refer to production and good workmanship. Tabular 1 Limits for linear measures Tolerance- class Limits in mm for nominal sizes in mm 0,5 to 3 above 3 to 6 above 6 to 30 above 30 to 120 above 120 to 400 above 400 to 1000 above 1000 to 2000 above 2000 to 4000 f fine ± 0,05 ± 0,05 ± 0,1 ± 0,15 ± 0,2 ± 0,3 ± 0,5 - m medium ± 0,1 ± 0,1 ± 0,2 ± 0,3 ± 0,5 ± 0,8 ± 1,2 ± 2 c coarse ± 0,15 ± 0,2 ± 0,5 ± 0,8 ± 1,2 ± 2 ± 3 ± 4 v very coarce grob - ± 0,5 ± 1 ± 1,5 ± 2,5 ± 4 ± 6 ± 8 For nominal sizes below 0,5 mm the limit measures are to be indicated directly at the nominal measure. Quality level B corresponds to the highest requirement on the finished weld. The actual size of an angle shall be determined by applying suitable measuring devices tangentially to the weldment, but away from the zone immediately influenced by the weld.
The principles of this standard may also be applied to partial-penetration butt welds. Standarden omfatter fuldt gennemsvejste stumpsømme og alle kantsømme. The deviation shall be derived from the difference between the nominal size and the actual size. Instead of specifying individual tol- erances, the tolerance classes according to this standard may be used. Subscription pricing is determined by: the specific standard s or collections of standards, the number of locations accessing the standards, and the number of employees that need access. Three quality levels are given in order to permit application to a wide range of welded fabrication.Next
They are designated by symbols B, C and D. General tolerances for form and position should be used while the tolerance principle according. By choosing the tolerance class precision levels common in workshops should be taken into account. It applys for material thicknesses over 0,5 mm. Tolerance class General tolerances for straightness and evenness in mm Range of specified size in mm to 10 above 10 to 30 above 30 to 100 above 100 to 300 above 300 to 1000 above 1000 to 3000 H 0,02 0,05 0,1 0,2 0,3 0,4 K 0,05 0,1 0,2 0,4 0,6 0,8 L 0,1 0,2 0,4 0,8 1,2 1,6 Tolerance class General tolerances for straightness and evenness in mm Range of specified size in mm to 100 above 100 to 300 above 300 to 1000 above 1000 to 3000 H 0,2 0,3 0,4 0,5 K 0,4 0,6 0,8 1 L 0,6 1 1,5 2 Tolerance class General tolerances for symmetry Range of specified size in mm to 100 above 100 to 300 above 300 to 1000 above 1000 to 3000 H 0,5 K 0,6 0,8 1 L 0,6 1 1,5 2 General tolerances for form and position are valid for form elements for which form and position tolerances are not indicated individually.Next
The length of the leg may also be assumed to extend to a specified reference point. This standard is also available to be included in Standards Subscriptions. The main crite- rion for the selection of a particular tolerance class should be the functional requirements which are to be met. The results of measurement may be influenced if they are obtained under unusual temperature or atmospheric condi- tions e. If the document is revised or amended, you will be notified by email. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, and conflicting national standards withdrawn, by February 1997 at the latest.
