welding processes (Page 4)

By Henry Cialone President & CEO, EWI EWI is quickly approaching our 40th year in business. These decades of experience have been filled with accelerating technological revolutions, dramatic market shifts, and major political changes worldwide. Staying ahead of the evolving needs of industry is something EWI prides itself on. In recent years, a request that...

Precise control of the wire electrode or “tool-point” position is critical in gas metal arc welding and arc directed energy deposition. Newly developed elliptical wire technology (EWT) offers improvements in tool-point control. Recently, EWI completed a study of EWT, comparing many of its features against standard round-wire electrode feedstock. The promising results are discussed in...

Integrated computational materials engineering (ICME) is an ever-growing field of study providing tools that can be directly applied to a range of manufacturing processes. Analytical modeling frameworks for assessing thermal excursions comprise a key element of welding ICME.  A useful subset of these frameworks can be employed to understand thermal excursions in welding and joining....
