11、f 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 steels. b) Part 2 covers stainless steels. c) Part 3 covers copper and copper alloys. d) Part 4
12、 covers aluminium and aluminium alloys and magnesium alloys. e) Part 5 covers nickel and nickel alloys. This Part of BS 2901 supersedes BS 2901-2:1983 which is withdrawn. In accordance with current practice, in deciding on the dimensions of wires and reels account has been taken of appropriate ISO (
13、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 and wires are not suitable for use with particular shielding gases. The chemical composition of the d
14、eposited 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 or wires are suitable for use with a particular shielding gas. Also for some applications a particula
15、r chemical composition may need to be selected from the range specified for the appropriate type of rod or wire. In this revision 14 new alloys have been introduced. Product certification. Users of this British Standard are advised to consider the desirability of third party certification of product
16、 conformity with this British Standard based on testing and continuing surveillance, which will be coupled with assessment of a suppliers quality systems against the appropriate Part of BS 5750. Enquiries as to the availability of third party certification schemes will be forwarded by BSI to the Ass
17、ociation 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 British Standard does not purport to include all the necessary provisions of a contract. Users of British Stan
18、dards 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, pages 1 to 8, an inside back cover and a back cover. This
19、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.

20、cope This Part of BS 2901 specifies requirements and chemical compositions for austenitic and ferritic/martensitic stainless steel filler rods and wires for gas-shielded arc welding, i.e. TIG-welding and MIG-welding. NOTEThe titles of the publications referred to in this Part of BS 2901 are listed o
21、n 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. If the delta-ferrite content in the deposited weld metal is important, then the purchaser shall indicate that he requires this to be determ
22、ined at the time of placing the order. NOTE 1The method to be used and the acceptable limits are to be the subject of agreement between the purchaser and the supplier. For the purposes of determining compliance with composition limits, any value obtained from the analysis shall be rounded to the sam
23、e 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 last figure to be retained shall be kept unchanged. b) When the figur
24、e 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 the figure immediately after the last figure to be retained is equal to
