Integrated computational materials engineering (ICME) principles can be applied to model thermo-mechanical material behavior in joining and additive manufacturing applications. Demonstrations and examples have been presented in several recent EWI publications.* The ICME framework can also offer a solution approach to modeling microstructural response in similar applications. EWI Principal Engineer Michael Eff and Senior Technology...

Part 1 in our GMAW series, Gas Metal Arc Welding Basics, Part 1: Welding Current and Voltage, discussed how variations in both welding current and welding voltage affect the penetration profile and bead profile of a weld.  In this installment, the variables of travel speed and contact tip to work distance  (CTWD) will be discussed...

For nearly a century, gas metal arc welding (GMAW) has been a mainstay of industrial fabrication. In this GMAW overview, we cover a range of topics that are critical to understanding and achieving potential applications from a detailed gas metal arc welding definition to the difference between GMAW and FCAW. What Is Gas Metal Arc...
