St For single-run fillet welds and butt welds made with a single run or a single-run each side and where weaving is used during the run, welding consumables selected in accordance with Table 4. Licensees are permitted to use the Aa the following extent: The two weld categories shall be designated as follows: If the weld does not comply, the location and extent of the defects shall 5154.1 given. Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of this Standard.
Flame cutting of steels Technical Note 6: Qualifications of welders see Clause 4. The transition slope between the parts shall be not steeper than 1: Equal width rectangular hollow sections Where the end of a rectangular hollow section member is welded to the surface of another rectangular hollow section member of equal width, the welding procedure shall be qualified in accordance with Clause 4. A procedure qualification on a double-J butt weld shall also qualify for welding a single-J butt weld that has been welded on both sides.
This Standard requires that weld preparations, welding consumables and welding procedures be qualified before commencement of welding. A change in welding direction between vertical up and vertical down shall require separate qualification.
AS 1554.1 & AS/NZS 1554.1
For system A classified consumables, consumables of the former positional class D are equivalent to position designation 3 including 4 and P are equivalent to designation 1 including 2 to 5. Standard quality requirements Bolted Column Splices with Minor Axis Bending In multistory construction columns splices are provided for convenience of fabrication, transport and erection.
The system A classification though remains consistent with the method used for other consumables types. In this article guidance is given on the modifications required to previously published 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.
Similarly, procedures qualified for category SP may be employed without further qualification for category GP of this Standard. To extend the validity of weld procedures qualified under previous classification systems to utilize consumables classified under the harmonized ISO based classification system, the procedure described in this Appendix should be adopted, and where contractually required, agreed between the fabricator and principal prior to the commencement of welding to minimize the need for the fabricator to requalify weld procedures.
High Strength Bolting Training Course. Where either of the two additional spots fail, the entire weld should be radiographed or replaced. Checklist for Imported Structural Steelwork The globalisation of the structural steel supply chain has sparked concern over the quality of fabricated steelwork in New Zealand building projects when sourced from low-cost countries.
Where the joint contains two welds, the size shall be the combined depths. Co py rig ht The Charpy-V test temperature shall be the lower of the relevant temperature given in Table 4.
The Licensee isLearn grantedabout a non-exclusive and non-assignable Licence to use the Product. Advantages of steel construction.
AS & AS/NZS – Australian Welding Institute
Structural steel ss Part 1: Where the root is to be gouged back to sound metal, the root tolerances given in Table 5. Test reports for non-destructive examination shall comply with the appropriate Australian Standard and shall include the following additional information: Where the weld complies with the relevant test requirements of Clause 4. This edition incorporates the following major changes to the edition: 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.
All t 12 max. Temporary backing material of any type may be used for welds, provided the finished weld complies with the requirements of this Standard. Licence means the right to access and use the Product.
Welding to AS/NZS of Boron Containing Steel
When applying this qualification for single-run and multi-run fillets, consideration shall be given to the pre-heat requirements for combined thicknesses of T1, T2 and T3, and the pre-heat requirements for the combined thicknesses shall be shown on the welding procedure specification Nza and on the procedure qualification record PQR.
Home As NZS Electrical Non-destructive testing—Penetrant testing of products and components Cast steels Co py rig Methods for destructive testing of welds in 15554.1 Method 2. Where non-complying welds are detected during a spot examination, two additional spots, each of the same length as the original spot, should be examined.
Guidance as to the extent of non-destructive examination is given in Table 7. Placing pieces of metal in the root gap 5154.1 bridging the gap is not permitted. A welding procedure qualified by another fabricator, see Clause 4. See Appendix D, Items g and h.
Specifying weld sizes larger than necessary shall be avoided. The rating SP compared with GP concerns weld quality and how it is inspected.
Guidance on appropriate post weld heat treatment may be found in AS See Appendix D, Item v. Any coating on the electrodes or filler wires shall be continuous and firmly adherent.
