This Standard incorporates Amendment No. 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.
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 also to some welds subject to fatigue. Although this Standard has been specifically prepared for steel structures, it may be usefully applied to machine frames and other types of steel constructions.
This edition incorporates the following major changes to the edition: This Standard requires that weld preparations, welding consumables and welding procedures be qualified before commencement of welding. Prequalified joint preparations, welding consumables and welding procedures are also given in the Standard.
This Standard, 15554.1 catering for structures subject to fatigue conditions as well mzs statically loaded structures, provides two categories of welds with two differing levels of weld quality assurance associated with the different types of service to which the welds are subjected. The intention is that the designer select the category suited to the severity aas the service and 11554.1 this on the drawings.
Where a structure contains both categories, this nomination of appropriate categories will ensure that appropriate levels of supervision and inspection will be applied to the relevant parts of the structure. Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of this Standard. This Standard is limited to the welding of steel parent material with a specified minimum yield strength not exceeding MPa.
Where welded joints in xs structures are governed by dynamic loading conditions, this Standard applies only to those welded joints that comply with the fatigue provisions of ASAS or NZS Welded joints complying with hzs above Standards are the following: In addition to the abovementioned structures, the Standard applies to the welding of cranes, hoists and other xs loaded structures, the welding of road and pedestrian bridges and the welding of steelwork in applications other than structural.
This Standard does not apply to the welding of pressure vessels and pressure piping. This Standard zs not apply to underwater welding. This Standard does not cover the design of welded connections or permissible stresses in welds, or the production, rectification or repair of castings. Documents referenced for informative purposes are listed in the Bibliography. Where the structure is not subject to statutory jurisdiction, the principal is deemed to be the inspecting authority.
The nominated representative should be suitably qualified to deal with the technical issues of this Standard. See Appendix D, Item a. The two weld categories shall be designated as follows: Welds nominated as Category SP, but not complying with the requirements of that category, may be considered as Category GP welds, provided the requirements of the design Standard are satisfied and the principal has agreed.
For certain conditions prescribed herein, the welding procedure is deemed to be prequalified and may not require full qualification testing see Clause 4. ASAS In particular, due consideration shall be given to the control of emitted fumes, especially when welding through paints, primers and other surface coatings. Any steel type from any of the above Standards may be welded to any other steel jzs from any Standard listed above, provided the requirements of this Standard are met for each of the steels.
AS 1554.1 & AS/NZS 1554.1
With the exception of quenched and tempered steels, parent materials not identified to a Standard nominated in Item c above may be used, provided one of the following requirements is met: Temporary backing material of any type may be used for welds, provided the finished weld complies with the requirements of this Standard. Electrodes that do not comply with the above Standards may be used, provided they are qualified in accordance with the requirements of Clause 4.
Filler wires shall be dry, smooth and free from corrosion or other matter deleterious either to satisfactory operation or to the weld metal. Any coating on the electrodes or filler wires shall be continuous and firmly adherent. Any recommendations of the manufacturer, covering protection during storage and use, conditioning and pretreatment of electrodes or filler wires prior to use, 5154.1 be followed.
Where the manufacturer makes specific recommendations covering conditioning and pretreatment of flux prior to use, such recommendations shall be followed.
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 condition for re-use. Flux fused in the welding process shall not be re-used.
Joint details that minimize stress intensity on parent materials subject to stress in the through-thickness direction shall be used where practical.
Specifying weld sizes larger than necessary shall be avoided. 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 the joint contains two welds, the size shall be the combined depths.
Licensed to Mr Vijai Moorthy on 31 March 15554.1 Appendix D, Item b. Where such penetration is achieved, 11554.1 size of the weld may be correspondingly reduced. 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 Ss 3.
Asnzs Compliance Requirements | Blog | Global Welding
The transition slope between the parts 1554.1 be not steeper than 1: Larger fillet welds are not permitted unless a compound joint see Clause 3.
Where there is a root gap, the size shall be given by the lengths of the legs of the inscribed triangle, reduced by the ass shown in Table E3, Appendix E.
For deep penetration fillet welds made by fully automatic arc welding processes, provided that it can be demonstrated by means of a 155.1 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.
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. Any segment of intermittent fillet weld shall have an effective length of not less than 40 mm.
Details of typical compound welds are shown in Figure 3. The size of seal welds shall comply with Clauses 3. See Appendix D, Item c.
Where seal welding is required, Clause 3. The centre-to-centre spacing between plug welds shall be not less than four times the diameter of the hole. 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. The depth of the filling of plug welds shall be as set out in Table 3.
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 containing the slot; and ii 2.
The ends of the slot shall be semicircular or shall have the corners rounded to a radius of not less than the thickness of the part containing it, except for those ends that extend to the edge of the part. The minimum spacing of lines of slot welds in a direction transverse to their length shall be four times the width of the slot. The minimum centre-to-centre spacing in a longitudinal direction on any line shall be two times the length of the slot.
The effective area of a slot weld shall be as for a fillet weld of the same size and effective length. Where a slot weld is made by completely or partially filling the slot i. See Appendix D, Item d. The fabricator shall establish a welding procedure and list the applicable parameters in the welding procedure qualification record also known as PQR or WPQRwhich shall be held as a record and shall be available for examination. A welding procedure specification shall be developed from the PQR, based on the limits of the essential variables of Clause 4.
