Prequalified joint preparations, welding consumables and welding procedures are also given in the Standard. See Appendix D, Item a.

The ultrasonic sensitivity to be used for parent metal scanning in weldung where welds are to be made should comply with ASi. V-notch impact test is required for heat-affected zone Where practicable, it is recommended that the principal resolve any problems with the fabricator, before work is commenced.
The transition slope between the parts shall be not steeper than 1: These standards are developed through an open process of consultation and consensus, in which all interested parties are invited to participate.
Details of typical compound welds are shown in Figure 3. For deep penetration fillet welds made by fully automatic arc welding processes, provided that it can be demonstrated by means of a macro test on a production weld that the required penetration has been achieved, an increase in design throat thickness shall be allowed as shown in Figure 3.
Should discontinuities be later detected in the weld heat affected zone it should be remembered that imperfections of parent metal origin are not considered a cause for rejection of the weld see Clause 6. The two weld categories shall be designated as follows: Table B1 may be used without modification for welded members and connection components that are not subjected to more than 1. The nominated representative should be suitably qualified to deal with the technical issues of this Standard.
The depth of the filling of plug welds shall be as set out in Table 3. This Standard is limited to the welding of steel parent material with a specified minimum yield strength not exceeding Strictures.
Where welds fail to meet the criteria of Table 6. Larger fillet welds are not permitted unless a compound joint see Clause 3.
AS/NZS 1554.1:2014 A1 Structural steel welding – Part 1: Welding of steel structures: Amendment 1
Licensed to Mr Vijai Moorthy on 31 March A completed welding procedure sheet WPStogether with records of tests carried out constitutes documentary evidence of prior experience. The system A classification though remains consistent with the method used for other consumables types.
Any coating on the electrodes or filler wires shall be continuous and firmly adherent. For welds on material with a thickness of more than 50 mm, evaluation shall be carried out at Level 3. For information about these services, users should contact their respective national Standards organization. Where the weld is full size throughout its length, no reduction in effective length shall be made for either the start or crater of the weld. This Standard was published on 25 November Where imperfections in excess of the limits in Table 6.
Welding positions shall comply with AS see also Table 4. The following are represented on Committee WD Transverse guided bend test Method 5. Where this is not possible, additional gain shall be added in accordance with Table 6. The main area of change affects the former type 12 and 13 designations which will now become type 13 although some type 13 consumables with good impact resistance due to the presence of basic minerals in the flux coating will most likely be classifiable as a type 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.
The Standards Council of New Zealand is the national authority responsible for the production of Standards. Welded joints complying with the above Standards are the following: Thursday, 31 March 4: The centre-to-centre spacing between plug welds shall be not less than four times the diameter of the hole. If the weld does not comply, the location and extent of the defects shall be given. The minimum centre-to-centre spacing in a longitudinal direction on any line shall be two times the length of the slot.
Examples include but are not limited to a change from V-shape to U-shape, a change from V-shape to bevel-shape. See Appendix D, Item k. Where a slot weld is made by completely strictures partially filling the slot i. In welds made from two sides, specimens shall be taken from the first welded side. This Standard, in catering for structures subject to setel conditions as well as statically loaded structures, provides two categories of welds with weldig differing levels of weld quality assurance associated with the different types of service to which the welds are subjected.
Where the consumable used to qualify a weld procedure has been identified on the weld procedure using its trade name and classification, the fabricator should append a note on the original procedure qualification record PQR noting the change of classification for the welding consumable. Premature failure at the corners of the test specimen shall not be considered cause for rejection.
See Appendix D, Item d. Guidance as to the extent of non-destructive examination is given in Table 7. This Standard does not apply to the welding of pressure vessels and pressure piping.
Thank you for interesting in our services. The objective of 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 sfeel to some welds subject to fatigue.
Where the weld complies with the relevant test requirements of Clause 4. Either— i the steel type number, as given in Table 4. For the purposes of Table 6.
Where the manufacturer makes specific recommendations covering conditioning and pretreatment of flux prior to use, such recommendations shall be followed. The appropriate steel type, suitable for the design service strel and material thickness, shall be selected in accordance with Paragraphs B4.
