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 for weld quality assessment solutions. EWI Senior Engineer Tim Frech has written Gas Tungsten Arc Welding In-process Monitoring Techniques for Electronic and Medical Device Applications to provide an overview of EWI’s investigation into real-time monitoring of gas tungsten arc welding using commercially available equipment.
