They should comply with the following, as appropriate: These zs are now consistent for all welding processes for which the harmonized ISO system has been applied.

The main risk of tearing is with cruciform, T- and corner joints and with complete penetration welds where high levels of strain are known to occur in the through-thickness direction in the element to which the connection is weldijg. The two weld categories shall be designated as follows: Welding power sources IEC Repaired welds shall be reinspected to the same level as that originally specified.

The extent, type and control of this documentation should be agreed prior to the commencement of the work see Appendix D.

Specifying weld sizes larger than necessary shall be avoided. The intention stductures that the designer select the category suited to the severity of the service and nominate this on the drawings.

AS/NZS 1554.1:2014 A1 Structural steel welding – Part 1: Welding of steel structures: Amendment 1

The minimum centre-to-centre spacing in a longitudinal direction on any line shall be two times the length of the slot. Hyperbaric dry welding Qualification testing of welders for underwater welding Part 1: See Appendix D, Item t and v.

Welded joints complying with the above Standards are the following: The objective 1554.1 this Standard is to provide rules for the welding of a wide range of steel constructions, and while it is expected that its main use will be for statically loaded welds, it applies also to some welds subject to fatigue. The holding of one of the following shall be accepted as evidence of these qualifications: The following are deemed to comply with this requirement: Diver-welders and welding operators for hyperbaric dry welding Licensed to Mr Vijai Moorthy on 31 March When applying this off for single-run and multi-run wwelding, consideration shall be given to the pre-heat requirements for combined thicknesses weldinv T1, T2 and T3, and the pre-heat requirements for the combined thicknesses shall be shown on the welding procedure specification WPS and on the procedure qualification record PQR.

This Standard requires that weld preparations, welding consumables and welcing procedures be qualified before commencement of welding. TM gradingno limitation on arc energy for single-run or multi-run technique. The width of the slot for slot welds shall be— a not less than the sum of 8 mm plus the thickness of the part containing the slot; and b not more than the greater of— i the sum of 11 mm plus the thickness of the part structtures the slot; and ii 2.

Where radiographic testing is used, 2 side bend or 1 face and 1 root bend tests are also required to qualify weld procedures and welders using either the GMAW or FCAW metal cored wire only processes.

Licensed to Mr Vijai Moorthy on 31 March Flux fused in the welding process shall not be re-used. Fracture mechanics Technical Note Visit our web sites www. Strructures a change in an essential variable for a welding procedure exceeds the relevant limits given in Table 4.

Where a non-destructive examination is specified, the drawings or other documents shall clearly state the methods to be used and the extent of testing to be carried out see also Clause 3. The appropriate steel type, suitable for the design service temperature and material thickness, shall be selected in accordance with Paragraphs B4.

structurds 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. We need your help to maintenance this website. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased.

Either— i the steel type number, as given in Table 4. Local strain due to weld distortion should be disregarded. Welding of high strength quenched and tempered steels Part 5: If any failure is due to cracking in the heat-affected zone or in the weld, the procedure shall be modified and a new procedure test plate shall be prepared.

Compression probes shall have a weldong frequency in the range 4 MHz to 5 MHz, and an essentially square or circular transducer in the size range 10 mm to 20 mm. For welds on material with a thickness of more than 50 mm, evaluation shall be carried out at Level 3.

These records shall be kept and made available to those authorized to examine them. Mr Vijai Moorthy Date:
