These documents govern the manufacture, assembly, and conformity assessment of steel and aluminum structures. Together, they set out requirements to ensure safety, reliability, and quality in construction products made from these materials. They provide requirements for design, qualification, fabrication, and inspection of welded aluminum structures. The AWS standards define welding procedures, qualification tests, criteria for evaluating weld quality, including visual inspection and nondestructive testing (NDT) and specify acceptance criteria for weld size, porosity, cracks, and other discontinuities.
This code covers the welding requirements for any type structure made from aluminum structural alloys, except for aluminum pressure vessels and pressure piping. Clauses 1 through 8 constitute a body of rules for the regulation of welding in aluminum construction. A commentary on the code is also included with the document.
Preface This is the second edition of CSA Standard W59.2, Welded aluminum construction. It supersedes the previous edition published in 1991 and CSA 5244-1969, Welded Design and Workmanship (Inert Gas Shielded Arc Processes), which was replaced by the 1991 edition. This edition represents a major rework of the Standard in both format and content. The following is a brief description of some of the most significant changes to the current edition of CSA W59.2: • the structure of this Standard has been modified to parallel CSA W59 where appropriate for ease of use; • Clause 3 has been revised to add several new materials; • Clause 5 includes new requirements for weld acceptance criteria; • Clause 7 has been reworked to provide clarity on roles and responsibilities for welding inspection; • Clause 8 has been added to provide comprehensive requirements for non-destructive testing; • Clause 10 has been added to provide requirements for friction stir welding; and • Annex A has been added to provide recommended joint geometries for aluminum welding. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 1.1 This Standard specifies the requirements for all types of welded aluminum construction with the exception of those types listed in Clause 1.2. Common requirements that are essential to all structures, including statically-loaded structures and cyclically-loaded structures, are included in this Standard. 1.2 This Standard is not intended to apply to pressure vessels or to structures governed by special codes such as those of the American Petroleum Institute, the American Society of Mechanical Engineers, or the American Water Works Association. 1.3 This Standard includes provisions for the following: a) gas metal arc welding (GMAW); b) gas tungsten arc welding (GTAW); c) plasma arc welding (PAW); d) friction stir welding (FSW); and e) stud welding (SW) by arc and capacitor discharge processes. 1.4 This Standard applies to the welding of base metals 2 mm (1/16 in) and thicker. 1.5 This Standard does not address safety problems associated with welding and welding practices. Note: CSA W117.2 addresses safety in welding, cutting, and allied processes, and should be followed in addition to any applicable workplace health and safety legislation in effect. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. 1.6 This Standard does not address underwater welding activities. 1.7 In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.8 The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
This European Standard specifies requirements for conformity assessment of performance characteristics for structural steel and aluminium components as well as for kits placed on the market as construction products. The conformity assessment covers the manufacturing characteristics, and where appropriate the structural design characteristics. This European Standard covers also the conformity assessment of steel components used in composite steel and concrete structures.
This European Standard specifies requirements for execution of structural steelwork as structures or as manufactured components, produced from:- hot rolled, structural steel products up to and including grade S700;- cold formed components and sheeting up to and including grade S700 (unless coming within the scope of prEN 1090-4);- hot finished or cold formed austenitic, austenitic-ferritic and ferritic stainless steel products;- hot finished or cold formed structural hollow sections, including standard range and custom-made rolled products and hollow sections manufactured by welding.For components produced from cold formed components, and cold formed structural hollow sections that are within the scope of prEN 1090-4, the requirements of prEN 1090-4 take precedence over corresponding requirements in this European Standard.This European Standard can also be used for structural steel grades up to and including S960, provided that conditions for execution are verified against reliability criteria and any necessary additional requirements are specified.This European Standard specifies requirements, which are mostly independent of the type and shape of the steel structure (e. g. buildings, bridges, plated or latticed components) including structures subjected to fatigue or seismic actions. Certain requirements are differentiated in terms of execution classes.This European Standard applies to structures designed according to the relevant part of the EN 1993 series. Sheet piling, displacement piles and micropiles designed to EN 1993-5 are intended to be executed in accordance with respectively EN 12063, EN 12699 and EN 14199. This European Standard only applies to the execution of waling, bracing, and connections.This European Standard applies to steel components in composite steel and concrete structures designed according to the relevant part of the EN 1994 series.This European Standard can be used for structures designed according to other design rules provided that conditions for execution comply with them and any necessary additional requirements are specified.This European Standard includes the requirements for the welding of reinforcing steels to structural steels. This European Standard does not include requirements for the use of reinforcing steels for reinforced concrete applications.
This European Standard specifies requirements for the execution of aluminium structural components and structures made from:a) rolled sheet, strip and plate;b) extrusions;c) cold drawn rod, bar and tube;d) forgings;e) castings.NOTE 1 The execution of structural components is referred to as manufacturing, in accordance with EN 1090-1.This European Standard specifies requirements independent of the type and shape of the aluminium structure, and this European Standard is applicable to structures under predominantly static loads as well as structures subject to fatigue. It specifies requirements related to the execution classes that are linked with consequence classes.NOTE 2 Consequence classes are defined in EN 1990.NOTE 3 Recommendations for selection of execution class in relation to consequence class are given in EN 1999-1-1.This European Standard covers components made of constituent products with thickness not less than 0,6 mm for welded components not less than 1,5 mm.This European Standard applies to structures designed according to the relevant parts of EN 1999. If this European Standard is used for structures designed according to other design rules or used for other alloys and tempers not covered by EN 1999, a judgement of the reliability elements in these design rules should be made.This European Standard specifies requirements for surface preparation prior to application of a protective treatment, and gives guidelines for application for such treatment in an informative annex.This European Standard gives options for specifying requirements to match project specific requirements.This European Standard is also applicable to temporary aluminium structures.
This European Standard specifies requirements for the execution, i.e. the manufacture and the installation, of cold-formed structural steel members and sheeting and cold-formed structures for roof, ceiling, floor, wall and cladding applications. This European Standard applies to structures designed according to the EN 1993 series. This European Standard applies to structural members andsheeting to be designed according to EN 1993-1-3. This European Standard may be used for structures designed according to other design rules provided that conditions for execution comply with them and any necessary additional requirements are specified. This European Standard also specifies requirements for the execution i.e. the manufacture and the installation of structures made from cold formed profiled sheeting for roof, ceiling, floor and wall applications under predominately static loading or seismic loading conditions and their documentation. This European Standard covers sheeting of structural classes I and II according to EN 1993-1-3 used in structures. This European Standard covers structural members of all structural classes according to EN 1993-1-3.
This European Standard specifies requirements for the execution i.e. the manufacture and the installation of cold-formed structural aluminium components made from profiled sheeting for roof, ceiling, floor and wall applications under predominately static loading conditions or seismic loading conditions and their documentation. It does cover products of structural class I and II according to EN 1999-1-4 used in structures. Structural elements are understood here to mean profiled sheeting, such as trapezoidal, sinusoidal, liner trays or cassette profiles (Figure 1), that are produced by cold forming. Perforated and micro profiled sheeting are also covered by this part. Welded sections are excluded from this part and are covered by EN 1090-3 except seal welding in low-stress areas. This standard also covers spacer constructions between the outer and inner or upper and lower skins as well as supporting members for roofs, walls and ceilings made from cold-formed profiled sheeting and the connections and attachments of the afore mentioned elements as long as they are involved in load transfer, it also covers connections and attachments of these elements. A combination of steel and aluminium structural elements are permitted, e. g. liner trays made of steel, stiffened by profiles made of aluminium. In this case, EN 1090-4 and this document apply. Composite structuralelements where the interaction between dissimilar materials are an integral part of the structural behaviour such as sandwich panels and composite floors are not covered by this standard.
