Qualification of NDE technicians see Clause 7.
Ze a The inspector shall have the nzd to witness all testing of welding procedures and welder qualification tests that are required.
Correction of faulty defective welds and cost of weld repair and associated NDE see Clauses 6. The size of an incomplete penetration butt weld shall be the minimum depth to which the weld extends from its face into the joint, exclusive of reinforcement. Restart the weld from the top of nxs taper slope.
Specifying weld sizes larger than necessary shall be avoided. Ultrasonic testing Clause 6. Any recommendations of the manufacturer, covering protection during storage and use, conditioning and pretreatment of electrodes or filler wires prior to use, shall be followed. In welds made from two sides, specimens shall be taken from the first welded side.
Any segment of intermittent fillet weld shall have an effective length of nz less than 40 15554.1. It is used as replacement for long bolts as well as for concrete anchors and foundation bolts.
Provided each preparation complies with the requirements of Table E2, Appendix E, for double-V, doublebevel, double-U or double-J welds, preparations of unequal depth shall be deemed prequalified also.
Excessive preheating should be avoided. Edge preparation Welding direction Range qualified Preheat temperature Method and check method 15541. temperature max. Any imperfections observed may be assumed to extend the total length of the weld, unless additional sections are taken to show the extent of the imperfections.
International Involvement Standards Australia and Standards New Zealand are responsible for ensuring that the Australian and New Zealand viewpoints are considered in the formulation of international Standards and that the latest international experience is incorporated in national and Joint Standards.
Guidance on appropriate post weld heat ws may be found in AS All reports, including calculations for fracture mechanics assessments of defective welds, shall be retained and made available for information purposes. The Charpy V impact test temperature of the other steel is not colder than that of the steel used in the qualified procedure.
AS 1554.1 & AS/NZS 1554.1
Either— i the steel type number, as given in Table 4. Hardness tests for the qualification of procedures employing consumables not prequalified shall show that the weld metal does not exceed the parent metal hardness by more than HV Visit our web sites www. In welds made from two sides, specimens shall be taken from the first welded side.
Flux fused in the welding process shall not be re-used. Only Sections U, X and Z apply to unequal-width rectangular hollow sections. The minimum spacing of lines of slot welds in a direction transverse to their length shall be four times the width of the slot. Placing pieces of metal in the root gap for bridging the gap is not permitted.
In order to assist us in reducing spam, please type the characters you see: These records shall be kept and made available to those authorized to examine them. A change in welding direction between vertically up and vertical down shall require separate qualification.
This strain arises from the shrinkage of the weld metal as it cools.

A Appendix D, Item f. For additional requirements for hollow sections, see Clause 4. Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of this Standard.
We need your help to maintenance this website. If any failure is due to cracking in the heataffected zone or in the weld, the procedure shall be modified and a new procedure test plate shall be prepared. Statements expressed in mandatory terms in nzz to tables and figures are deemed to be requirements of this Standard.
Under certain circumstances, such as an unusual joint configuration, it may be necessary to prepare two test pieces for different purposes, one as shown in Figure 4. Control of lamellar tearing Technical Note 7: Provided each preparation complies with the requirements of Table E1 for double-V, double bevel, double-U and double-J welds, preparations of unequal depth shall be deemed prequalified also.

Where welded joints in these structures are governed by dynamic loading conditions, the Standard applies only to those 15541 joints that comply with the fatigue provisions of ASAS or NZS See Appendix G for guidance on the relationship between these steels ws material group numbers utilized in other Standards.
Eccentrically Braced Frames with Removable Links – Design Example Steel eccentrically braced aw are expected to sustain damage during a design level earthquake through repeated inelastic deformation of the active link. Typical flattened circular hollow section joints are shown in Figure 4. Documentation required All welding and fabrication work must be performed using qualified procedures. Please address your comments to the Chief Executive of either Standards Australia or Standards New Zealand at the address shown on the 154.1 cover.
Based on records during the years to as supplied by the National Institute of Water and Atmosphere Research. Electrical Certification of welders and welding supervisors Diver-welders for hyperbaric wet welding Part 2: Where a change in an essential variable for a welding procedure exceeds the relevant limits given in Table 4. A fillet weld shall be used throughout. See Appendix D, Item t and v. St The gap between parts shall normally not exceed nnzs mm. With the assistance of a W.
Fire precautions Part 2: For other steel types not listed in Table 3.
