GB/T3197.-2001
This standard is a revision of GB/T3197-1982 Aluminium and alloy wires for far welding purpose3. Compared with B/T3107-108, this standard has the following changes: the new national standard character system alloy grade code and the addition of commonly used foreign gold-containing grades; the wire diameter allowable deviation is divided into two levels: ordinary and commercial grades. This standard replaces G13/T319-1982 from the date of implementation. This standard is mainly issued by the China Nonferrous Metals Industry Association. This standard is also the responsibility of the China Nonferrous Metals Industry Standardization Quality Research Institute. This standard is mainly drafted by Northeast Light Alloy Co., Ltd., the North China Light Alloy Factory, and the National Institute of Standardization. This standard is interpreted by the National Nonferrous Metals Standardization Technical Committee. Scope
