This is particularly relevant when the direction of loading is normal to the plate surface Z direction.

Please fill this form, we will try stewl respond as soon as possible. For welds on material with a thickness of more than 50 mm, evaluation shall be carried out at Level 3. Provided each preparation complies with the requirements of Table E2, Appendix E, for double-V, double-bevel, double-U or weldig welds, preparations of unequal depth shall be deemed prequalified also.

Repaired welds shall be reinspected to the same level as that originally specified. Thursday, 31 March 4: Inspection aids and measuring devices shall be sufficient to enable the inspector to detect imperfections that could occur on welds and test pieces.

AS/NZS – Standards Australia

To maintain their currency, all Standards are periodically reviewed, and new editions are published. In all other cases or where equivalence cannot be 15554.1, it will be necessary to requalify the weld procedure in accordance with the requirements of this Standard. Weldability of steels Technical Note 3: Where the manufacturer makes specific recommendations covering conditioning and pretreatment of flux prior to use, such recommendations shall be followed.

The connections shown in Figure 4. 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. Unless it can be proved otherwise for the remainder of the test plate e.

Shear probes shall have a dominant frequency in the range 2. Strucutres by other portions of the Medium restraint: This Standard does not cover the design of welded connections or permissible stresses in welds, or the production, rectification or repair of castings. The inspector shall make a careful and systematic check to ensure that no welds called for in the drawings are omitted.

The inspector shall have access at all reasonable times to all relevant phases of the work, and shall be given reasonable notice in advance of the start of welding operations. For plate thicknesses of less than 15 mm, the transducer size may be reduced to 8 mm and frequencies increased to 5 MHz. For MMAW consumables, the situation is more complex as impact energy requirements for system B classified consumables follows the current AWS practice of defining minimum requirements for each electrode class and composition.

In special cases, metal temperatures cooler than the LODMAT may occur where there is minimum insulation, minimum heat capacity, minimum radiation shielding or abnormally low local temperatures such as snow, ice and frost conditions.

The ultrasonic sensitivity to be used for parent metal scanning in areas where welds are to be made should comply with Weldimgi. Typical joint preparations for connections butt-welded from one side are shown in Figure 4. Joint identification Close-joint square butt weld, welded both sides Manual metal-arc Submerged arc t 3 max.

The change of shape shall be gradual, with no evidence of splitting or cracking in the flattened portion. 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 as to the extent of non-destructive examination is given in Table 7. In addition to the abovementioned structures, the Standard applies to the welding of cranes, hoists and other dynamically loaded structures, the welding of road and pedestrian bridges and the welding of steelwork in applications other than structural. Where the joint contains two welds, the size shall be the combined depths. Filters for protection against radiation generated in welding and allied operations Hot-rolled steel flat products Cold-rolled, unalloyed, steel sheet and strip Welding cables Qualification of welders for fusion welding of steels Structural steel—Hot-rolled plates, floorplates and slabs Electrodes that do not comply with the above Standards may be used, provided they are qualified in accordance with the requirements of Clause 4.

Where there is a root gap, the size shall be given by the lengths of the legs of the inscribed triangle, reduced by the amount shown in Table E3, Appendix E. Both retests shall comply with the test requirements. See Appendix D, Item d.

The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected. Filler wires shall be dry, smooth and free from corrosion or other matter deleterious either to satisfactory operation or to the weld metal.

Where matching weathering properties are required, refer to Table 4. Where a change in an essential variable for a welding procedure exceeds the relevant limits given in Table 4.

Classifications shall also comply with the relevant strength and impact designations shown in Table 4.
