10、 of the Welding Standards Committee, supersedes BS 5465:1977, which is withdrawn. As with the 1977 edition the basis of the standard is the chemical composition of the deposited weld metal which, as before, has been aligned with BS 2926. However, in addition chemical compositions of electrodes are n
11、ow introduced and where possible these align with those given in BS 2901-2. This standard has been written in a manner that will not inhibit developments in wire/flux combinations. Factors other than weld metal composition can influence the suitability of any wire/flux combination and these have to
12、be taken into account relative to the particular fabrication, e.g. weld contour, penetration and appearance. The user is advised, therefore, to carry out welding procedure tests to simulate his product application. Although combinations of wires and fluxes supplied by different companies may comply
13、with this standard, individual wires and fluxes are not necessarily interchangeable. It has been assumed in the drafting of this British Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. A British Standard does not purport to include all th
14、e necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii,
15、 pages 1 to 8, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. Licensed Copy: sheffieldun sheffieldun, na, Fri Dec 01 14:45:07 GMT+00:00 2006,
16、 Uncontrolled Copy, (c) BSI BS 5465:1987 BSI 09-19991 1 Scope This British Standard specifies requirements for bare electrode wire (solid or cored), strip electrodes and fluxes for the submerged arc welding of austenitic stainless steels based on weld metal composition. NOTE 1Information on flux typ
17、es for submerged arc welding and surfacing and process characteristics is given in Appendix A. NOTE 2The titles of the publications referred to in this standard are listed on the inside back cover. 2 Information to be supplied by the purchaser When ordering an electrode and flux combination that com
18、plies with this standard, purchasers shall state: a) the number and date of this British Standard, i.e. BS 5465:1987; b) the classification according to the composition of the weld metal (see clause 3 and Table 1); c) the size of electrode (see clause 4) and the dimensions and mass of coil (see clau
19、se 6); d) whether test certificates are required for flux and/or electrode composition (see clauses 9 and 10); e) whether certificates are required for initial and/or periodic weld metal analysis tests carried out by the manufacturer (see 11.3); f) whether any additional tests are required, e.g. fer
20、rite content, mechanical properties and confirmatory weld metal analysis on the batches of electrode and flux supplied (see clause 12). NOTEWhere a purchaser orders electrodes without specifying the flux to be used, the designation for electrodes and composition limits given in Table 2 may be used a
21、nd reference made to this standard but the weld metal classification should not be quoted. If electrodes and flux are ordered separately (whether from the same or different manufacturers) it should not be assumed that the weld metal deposited will comply with a particular classification given in Tab
22、le 1. In such circumstances the purchaser is recommended to seek guidance from the manufacturer(s) or carry out his own tests to ensure the electrode/flux combination meets his particular requirements. 3 Classification The classification of electrode/flux combination, according to the composition of
23、 the deposited weld metal, shall be indicated by the following coding, as relevant, each figure in the following sequence being separated from the next figure by a full stop (see Table 1): Example: Weld metal with the following composition will be classified as follows: NOTEManufacturers of electrod
24、es and flux combinations which comply with this standard should provide on request current lists of their product range with details of compliance. Additionally they should provide guidance on the weld metal composition and properties likely to be achieved in circumstances where dilution with parent

32、however, the figures to be discarded fall exactly midway between two alternative prospective round values and there is no evidence to indicate in which direction to round, choose the even round value. For example: 0.105 rounds to 0.10; 0.95 rounds to 1.0. b The nickel content is usually analysed as
33、nickel plus cobalt; for some applications a limit for cobalt may need to be agreed between the purchaser and the manufacturer. c The niobium content is usually analysed as niobium plus tantalum; for some applications a limit for tantalum may need to be agreed between the purchaser and the manufactur
34、er. d Electrode designation is that normally used to achieve the corresponding weld metal composition when welds are made with a flux recommended by the manufacturer. e In cases of high restraint, or where fully austenitic weld metal could arise, a lower limit should be agreed between the purchaser
35、and the manufacturer. f When a low delta ferrite content is required, the maximum nickel content may be increased. g Where the weld metal will be in service above 650 C there may be a risk of catastrophic oxidation at molybdenum levels of 0.5 % and a lower level should be agreed between the purchase
36、r and the manufacturer.
