4、chuss Schweitechnik NAS (Welding Standards Committee). It is intended to submit this document to CEN/TC 121 “Welding” as a proposal for a European Standard. Amendments This standard differs from DIN 2559-3:1990-10 as follows: a) Dimensions and tolerances have been harmonized with DIN EN 10217-1:2005

5、-04 and DIN EN 10217-2:2005-04. Previous editions DIN 2559-3: 1990-10 1 Scope This standard specifies matching dimensions for butt joints welded from one side, with joint preparation as in DIN EN ISO 9692-1, for welded steel tubes having dimensions and tolerances as in DIN EN 10217-1:2005-04, 8.7 or

6、 DIN EN 10217-2:2005-04, 8.7. This document helps ensure proper matching of diameters and wall thicknesses without extensive corrections being necessary. This document may also be applied to other cylindrical hollow bodies, by analogy. 2 Normative references The following referenced documents are in

Before welding, the weldability of the joint shall be established on the basis of the permissible edge offset. If the edge offset conditions are not met

21、, another manufacturing process shall be chosen, e.g. reducing, deposit welding, or widening. If the inside diameters of a joint to be welded are comparable, it is only necessary to match the smaller inside diameter to the larger inside diameter, taking care that the remaining joint wall thickness i

The wall thickness may only be smaller than the tpvalue specified in Tables 5 and 6 if further calculations show that the remaining wall thickness is within the specified limits. If, when welding tubes having the same

23、 nominal dimensions, the inside diameter of one side does not match, this diameter shall be measured again. If the re-measured value is smaller than the matching diameter required for this particular joint, then the measured smaller diameter shall be adjusted to match the larger inside diameter of t

The adjusted wall thickness may only be smaller than tpas in Tables 5 and 6 if further calculations show that the remaining wall thickness is within specified limits. DIN 2559
