9、d in a drawing or a technical supply specification or if its application is agreed as part of other specifications.If the drawings or other specifications (e.g. those of the responsible engineering departments or rework catalogs) contain individual deviating stipulations, then these shall have prior

10、ity. Likewise, a component-specific test specification has priority over this VW standard if this is defined in the drawing.The joint types described in this standard are ideal representations. Welded seams that are not shown are to be treated analogously.The standard is divided into evaluations of

11、type A and type B. If the index is not given in the drawing, type A shall be used for the evaluation.Type B stipulates slightly lower requirements for some evaluation criteria. The responsibility for allocating joints to type B rests with the engineering department.2 Requirements and evaluation OK e

12、valuati on:The test according to VW 011 06-3 is evaluated as OK if the welded seams comply with thelisted evaluation criteria. Conditionally OK evaluation:The test according to VW 011 06-3 is evaluated as being conditionally OK if max. 2“soft ”evaluation criteria according to Table 2:, Table 4:, Tab

13、le 6: or Table 8: are not OK. The evaluation criteria according to table 1, Table 3:, Table 5: and Table 7: as well as the porosity evaluation according to Table 9: must be OK under all circumstances. Steps must be taken to ensure that the items that were not OK are rectified. Not OK evaluation:The

14、test according to VW 011 06-3 is deemed not to be OK in all other cases.3 Test3.1 Characteristics for the external findingsAccording to Table 1: and Table 2: by visual test.The dimensions, position, number and presence of seams are evaluated according to the drawing and the evaluation criteria set o

15、ut in Table 1: and Table 2: in a visual test.The test is performed with the naked eye. In case of doubt, other suitable test procedures and/or equipment must be used (e.g., magnifying glass, stereo microscope, dye-penetration procedure).3.2 Characteristics for the internal findingsAccording to Table

16、 3: to Table 9: by evaluating microsections.page 6VW 011 06-3: 2002-043.3 SamplingUnless otherwise agreed between the engineering departments, metallographic microsections shall be taken from each welded seam at the specified points, cross-wise to the direction of the seam (e.g. defined in TLD sheet

17、s, PVs or ground section plans).The microsections are sawn, ground and polished.Additional microsections can be taken in the direction of the seam if required.Recommended specimen removal:Seam length 50 mmSeam length 100 mmSeam length 10 mm4 EvaluationcriteriaThe evaluation takes the form of a visua

18、l inspection of the seam (section 4.1), a test of the seam and penetration geometry (sections 4.2 to 4.4) and a test of the porosity (section 4.5). A reflected light microscope must be used for evaluation as per sections 4.2 to 4.5. The use of a stereo microscope can also be agreed; however, impairm
