EWI’s Green Laser Capability for Electrification, Copper Welding, and DED By Jacob Hay The use of industrial lasers for manufacturing has been gaining popularity for decades as laser sources have improved in efficiency and reliability. A properly selected laser energy source combined with the right system can offer great flexibility, providing varying energy densities, wavelengths, and...

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...
