Advanced Methods for Highly-Portable Field Repair Welding and Assessing Phase Stability and Aging of Alloys in Service

Abstract

New welding consumables and practices for weld repair are being investigated. Special attention was given to the repair of light metals (aluminum and magnesium alloys). Metal powder filled cored aluminum wires to be used with microwire GMA spool hand held guns were being developed. The use of strip-to-wire mill to make powder metal-cored wires was being perfected as an effective methodology for making specialty alloy welding consumable wires. These wires are for repairing technical assemblies made of specialty alloys. New non-destructive electronic property measurement techniques were investigated to assess the service life of time-dependent alloys, to determine the residual stress associated with welds and to assess the corrosion life of structures.
