GTAW In-process Monitoring Techniques for Electronic and Medical Device Applications
Electronic and medical device manufacturers not only require joining processes capable of producing small-scale welds of high quality, but also reliable methods of nondestructively assessing them. While real-time monitoring is well-developed for small-scale resistance welding, small-scale laser welding has no viable option. Gas tungsten arc welding (GTAW) presents an alternative welding approach with greater potential […]

The Art of Narrow-groove Welding
Narrow-groove (NG) welding is defined, in part, by the American Welding Society (AWS) as “a variation of a multiple-pass welding process with filler metal, using a small root opening and a V-groove with a small groove angle”. This yields a weld with a high ratio of depth to width. Narrow-groove welding techniques are well-established for […]

Orbital Welding: Don’t Be Afraid, It Can Be Your Friend
EWI is capable of performing orbital welding, a specialized welding process whereby the arc is rotated mechanically around a static workpiece such as a pipe in a continuous process. The technique was developed over 50 years ago, and with today’s modern technology is a sound, robust, and easy-to-use method of joining cylindrical components. These components can be […]

Material Properties for Arc-Based Additive Manufacturing of Ti 6-4 ELI
An area where EWI is expanding its knowledge is in characterizing and cataloging mechanical properties of additively manufactured metals (metals AM). The work described here was performed to obtain baseline mechanical property data for Ti 6-4 ELI weld metal buildups that were produced using hot-wire gas tungsten arc welding (GTAW-HW). The equipment used to weld […]
