This document provides manufacturing and process router instructions written by James H. Howard for General Electric Aviation. It includes over 50 process sheets for brazing and furnace brazing cycles, heat treatments using vacuum and inert gas, chemical bath processes, machining, welding, and other miscellaneous processes. The instructions cover areas such as thermal barrier coating removal, brazing alloys, etching solutions, hot isostatic pressing, and gas tungsten arc welding of jet engine components.
