E-Book Overview
American Iron and Steel Institute (AISI). Handbook Series # 9 002. 2002. 18p. The purpose of this booklet is to help designers and manufacturing engineers achieve a better understanding of the welding characteristics of stainless steels, so they may exercise better control over the finished products with respect to welding. In addition to welding, other ancillary joining methods are discussed, including soldering and brazing.
