دانلود کتاب Specification for Fluxes for Brazing and Braze Welding

This Specification prescribes requirements for the classification of brazing fluxes used with brazing or braze welding filler metals and is essential to today’s purchaser and welding professionals. Fifteen fluxes for brazing and braze welding are classified according to the filler metal, form, and activity temperature range. Classification is in accordance with a new classification system that employs the designator “FB” to indicate fluxes for brazing and braze welding applications. In addition to selected tests for each classification, major topics include general requirements, testing procedures, and packaging requirements. The Appendix suggests some general application guidelines. Content: Front Matter • Statement on Use of AWS American National Standards • List of Tables • List of Figures • Table of Contents • 1.
