10、T+00:00 2006, Uncontrolled Copy, (c) BSI BS 2901-5:1990 ii BSI 01-2000 Foreword This revision of this Part of BS 2901 has been prepared under the direction of the Welding Standards Policy Committee. BS 2901 is published in Parts covering the following types of consumables. a) Part 1: covers ferritic
11、 steels; b) Part 2: covers stainless steels; c) Part 3: covers copper and copper alloys; d) Part 4: covers aluminium and aluminium alloys and magnesium alloys; e) Part 5: covers nickel and nickel alloys. This Part of BS 2901 supersedes BS 2901-5:1983 which is withdrawn. In accordance with current pr
12、actice, in deciding on the dimensions of wires and reels, account has been taken of appropriate ISO (International Organization for Standardization) specifications. Although the rods and wires specified in this Part of BS 2901 are all suitable for some form of gas-shielded arc welding, certain rods
13、and wires are not suitable for use with particular shielding gases. The chemical composition of the deposited weld metal is not specified because this depends on the shielding gas used and the particular welding conditions. It is necessary, therefore, to ascertain from the supplier whether the rods
14、or wires are suitable for use with a particular shielding gas. Also for some applications a particular chemical composition may need to be selected from the range specified for the appropriate type of rod or wire. In this revision six additional alloys have been included. Product certification. User
15、s of this British Standard are advised to consider the desirability of third party certification of product conformity with this British Standard based on testing and continuing surveillance, which may be coupled with assessment of a suppliers quality systems against the appropriate Part of BS 5750.
16、 Enquiries as to the availability of third party certification schemes will be forwarded by BSI to the Association of Certification Bodies. If a third party certification scheme does not already exist, users should consider approaching an appropriate body from the list of Association members. A Brit
17、ish Standard does not purport to include all the 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 fron
18、t cover, an inside front cover, pages i and ii, pages 1 to 6, 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 sheff

NOTETh
20、e titles of the publications referred to in this Part of BS 2901 are listed on the inside back cover. 2 Chemical composition The rods and wires shall have a chemical composition in accordance with Table 1 for the particular type ordered. For the purposes of determining compliance with composition li
21、mits, any value obtained from the analysis shall be rounded to the same number of decimal places as used in this standard in expressing the specified limit. The following rules shall be used for rounding. a) When the figure immediately after the last figure to be retained is less than five, then the
22、 last figure to be retained shall be kept unchanged. b) When the figure immediately after the last figure to be retained is either: 1) greater than five; or 2) equal to five and followed by at least one figure other than zero; then the last figure to be retained shall be increased by one. c) When th
23、e figure immediately after the last figure to be retained is equal to five, and followed by zeros only, then the last figure to be retained shall be left unchanged if even, and increased by one if odd. In cases of dispute regarding the chemical composition of the rods and wires, sampling and check a
