Welding to AS/NZS of Boron Containing Steel

Prequalified joint preparations, welding consumables and welding procedures are also given in the Standard. Thus, such instructions should be agreed between the fabricator and principal. For certain conditions prescribed herein, the welding procedure is deemed to be prequalified and mzs not require full qualification testing see Clause 4.

Where welded joints in these structures are governed by dynamic loading conditions, the Standard applies only to those welded joints that comply with the fatigue provisions of ASAS or NZS Table B1 may be used without modification for welded members and connection components that are not subjected to more than 1.

Where a change in an essential variable for a welding procedure exceeds the relevant limits given in Table 4. For the purpose of this requirement, a digital or scanned image is considered to be the equivalent of a photograph.

Where a consumable is not prequalified in accordance with Items abc d or e above, but the fabricator can produce relevant data, properly documented, of satisfactory prior experience in the use of the consumables with a qualified procedure, the data shall be taken as sufficient evidence for deeming the consumable qualified for that procedure see Clause 4. The inspector should be certified as 1554.1 to inspect at the level required by the Principal or Inspecting Authority.

The following are represented on Committee WD Tearing at the ends of imperfections shall not be considered for the purposes of assessing the depth or height of imperfections.

Where routine testing reveals imperfections requiring further consideration in accordance with Section 6, Clause 6. Gouged areas requiring re-welding shall have a root radius of not less than 5 mm and sufficient width to allow the welder reasonable access to reinstate the weld. Where imperfections in excess of the limits in Table 6. Care and conditioning of arc welding consumables Technical Note 5: The size of a complete penetration T-joint or corner joint butt weld shall be the thickness of the part that butts against the face of the other part.

Where lack of root fusion is evident, the inspector is required to assess the approximate depth of the imperfection.

The effective area of a plug weld shall be the nominal cross-sectional area of the hole in the plane of the faying or contact surface. All new WPS documents should then refer to this modified classification. This Standard is limited to the welding of steel parent material with a specified minimum yield strength not exceeding MPa. 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.

The change of shape shall be gradual, with no evidence of splitting or cracking in the flattened portion. Examples include but are not limited to a change from V-shape to U-shape, a change from V-shape to bevel-shape. In most cases extending the procedure qualification will be particularly if both the trade name and classification of the welding known.

Well these standards are created to make sure all parties have a foundation, a level playing field, to work on as an absolute minimum guarantee of a certain level of quality.

For calculation of the loss of cross-sectional area, internal imperfections are estimated from the macro test specimen. Ze a Surfaces and edges to be welded shall be uniform and free from fins, tears, cracks and other defects that would adversely affect the quality or strength of the weld.

AS 1554.1 & AS/NZS 1554.1

For critical joints, bead placement should be carefully considered by the fabricator when developing the welding procedure specification. 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 Weld joint hardness test Method 7.

Based on records during the years to as supplied by the Australian Bureau of Meteorology. In particular, due consideration shall be given to the control of emitted fumes, especially when welding through paints, primers and other surface coatings. This Table identifies nearest equivalent designations.

Test reports for non-destructive examination shall comply with the appropriate Australian Standard and shall include the following additional information: The two weld categories shall be designated as follows: See Appendix D, Item b. Weld joint hardness test Method 7. For information about these services, users should contact their respective national Standards organization.
