Subscription – always available nkrsok updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. A norsko defect rate may be used as basis for a reduction in the extent of NDT for inspection categories B, C and D, provided that a correct defect rate identification is prepared for each weld method, each NDT method b and each production area, see Table 3, table footnote. Non-destructive testing of welds — Magnetic particle testing.
Size px x x x x Crevices and areas which become inaccessible after fabrication or assembly shall be sealed off from the outside atmosphere.
Partial NDT shall normally be planed for on all shop drawings. Testing performed shall be representative for the weld quality.

At a weekly high defect rate or at repeated occurrence of planar defects, two trigger levels apply for extended NDT for welds in inspection category B, C norso, D. Maximum temperature for straightening shall not exceed the temperature limit recommended by the steel manufacturer, but it shall in no case be higher than qC.
The temperatures shall be continuously and automatically recorded on a chart.
We are a non-profit group that run this website to share documents. In addition new annexes have been included. If indicated on design drawings that removal full or partial is not required, the temporary attachments may be left as is, or removed only partially.

Buttering shall be welded in accordance noesok applicable WPS. If not specified, the requirement for minimum CTOD value shall be as for the steel purchase order. The defect rate statistics shall be used as norsoj tool in weld quality noorsok. All specimens shall be machined with the notch through the thickness, 2 mm below the surface of the material. Causes for defects shall immediately be investigated and corrective actions shall be taken to prevent further occurrence.
NS latest revision may be used.
NOTE 2 For highly fatigue utilized structures, more severe requirements may apply, and these will be shown on the design drawings. However, ambiguous imperfections revealed by UT shall in addition be tested by RT; d ultrasonic testing is normally not applicable for thicknesses less than 10 mm.
The holding time and temperature shall be as recommended by the steel manufacturer. Three valid test specimens shall be obtained for k test position.
Assemblies shall be made and tested for the actual combination of steel manufacturer, welding process and welding consumable brand used, except welding consumables used for j passes only, provided these are removed completely by gouging and grinding.

Final inspection and NDT of structural steel welds shall not be carried out before 48 h after completion except where PWHT is required. Testing shall be performed in accordance with ISO and the additional requirements given below.
Reference samples for typical joints and sections may be prepared and used for acceptance of treated welds.
Please fill this form, we nrosok try to respond as soon as possible. The manufacturers shall ensure that welding consumables applied for joints where steel quality level I, II and III are required, meet the requirements for mechanical properties as specified for the welding procedure qualification, in both as welded and where applicable PWHT condition.
Weld improvement by peening shall be performed in accordance with detailed procedures.
Ultrasonic testing to reveal the presence of possible weld metal transverse cracking shall be included for butt welds with thickness more than 25 mm. The number of procedures to be re-qualified shall be sufficient to verify that the HAZ properties of the new material is comparable with that used for the previous qualifications.
Please help us to share our service with your friends. All other personnel who are carrying out one or more welding activities according to ISOAnnex B, are welding coordinators.
The soundness of the weld shall comply with Clause 9. For welds with a joint thickness T!
