Criteria for the selection of the appropriate level of quality requirements Except where a greater hardness is permitted in accordance with Appendix D, Item i , the hardness of weld-heat-affected zones shall be not greater than HV Health and safety in welding Technical Note Where matching weathering properties are required, refer to Table 4. Flame cutting of steels Technical Note 6: Low carbon steel electrodes for manual metal-arc welding of carbon steels and carbon-manganese steels superseded Part 2:

Repaired welds shall be reinspected to the same level as that originally specified. Welding of high strength quenched and tempered steels Part 5: Re-qualification is not required where the change in classification is due to a change in classification Standard and equivalence is established see Clause 4. A procedure as/ns for use with a carbon or carbon-manganese steel may be employed without further qualification testing on any other carbon or carbon-manganese steel, provided all of the following apply: Transverse guided bend test Method 5.

AS/NZS - Standards Australia

The transition shall be made by chamfering the thicker part or by sloping the weld surfaces, or by any combination of these as shown in Figure 3. Where flux is re-used, flux-recycling systems shall include suitable sieves and magnetic particle separators and shall be such that the flux remains in a satisfactory 1554. for re-use.

All reports, including calculations for fracture mechanics assessments of defective welds, shall be retained and made available for information purposes. Consumables with T grading, no limitation on arc energy for single-run or two-run technique.

Any segment of intermittent fillet weld shall have an effective length of not less than 40 mm. The main risk of tearing is with cruciform, As/nze 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 made.

ASAS The inspector shall have the opportunity to witness all testing of welding procedures and ws/nzs qualification tests that are required. This Standard is limited to the welding of steel parent material with a specified minimum yield strength not exceeding MPa.

We also welcome suggestions 15541. improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. Premature failure at the corners of the test specimen shall not be considered cause for rejection.

Licensee means the purchaser and user of the Product. Transverse butt tensile test Method 3. Xs/nzs Availability See publications the 15554.1 Subject 2. The minimum centre-to-centre spacing in a longitudinal direction on any line shall be two times the length of the slot. It should then involve a progressive reduction in frequency of testing, on the basis of achieving compliance with each test.

On the completion of the test, the dimension of any crack or other defect in the weld or the heat-affected zone shall be not greater than 3 mm, measured in any direction at the outer surface of the test specimen. Care should be taken in applying this Table to imported steels as verification tests may be required.

The width of the slot for slot welds shall be— a not less than the sum of 8 mm as/nze 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 containing the slot; and ii 2.

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. They should comply with the following, as appropriate: In special cases, metal temperatures cooler than the LODMAT may occur where there is 15554.1 insulation, minimum heat capacity, minimum radiation shielding or abnormally low local temperatures such as snow, ice and frost conditions.

The minimum spacing of lines of slot welds in a direction transverse to their length shall be four times the width of the slot. These records shall be kept and made available to those authorized to examine them.

Parent metal discontinuities which interfere with the examination should be reported to the principal and included in the test report. Provided that the fabricator has included sufficient information to correctly identify the trade name and previous classification of consumables used to qualify their weld procedures, the procedure tests do not need to be repeated with the adoption of the ISO based classification system.

Charpy V-notch impact fracture toughness test Non-destructive testing—Ultrasonic testing of fusion welded joints in carbon and low alloy steel Certification of welding supervisors—Structural steel welding Radiography of metals—Image recommendations for their use Resistance welding equipment—Single-phase a. Where the joint contains two welds, the size shall be the combined depths. 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 Such variations include transducer sizes and frequencies.

Where seal welding is required, Clause 3. The specimen shall comply with the requirements of Clauses 5.
