Last week EWI had the first EWI ShipIt! Days. Employees were given 24-hours to do anything they wanted that wasn’t related to their regular job. The catch? You have to deliver something at the end of the 24-hours. This commercial about EWI is what my team delivered. Enjoy!!   [youtube http://www.youtube.com/watch?v=VF41VzcjpZ4]   If you areRead more

Should you Solder it or Braze it?

By Steve Massey on Thursday, February 20th, 2014 in Advanced Energy, Aerospace, Automotive, Defense, EWI – Company, Government, Laser Processing, Materials Engineering, Soldering and Brazing. No Comments

We receive  many questions about the difference between soldering and brazing.  They are very similar joining techniques, both involving the melting of a filler metal to join two or more components without melting the base material of the components.  The American Welding Society (AWS) defines brazing as such a process which involves a filler metalRead more

Material Properties for Arc-Based Additive Manufacturing of Ti 6-4 ELI

By Steve Massey on Tuesday, May 21st, 2013 in Aerospace, Arc Welding, Defense, EWI – Company, Government, Materials Engineering. No Comments

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 weldRead more

EWI Celebrates Engineer’s Week 2013

By Steve Massey on Wednesday, February 27th, 2013 in Advanced Automation, Arc Welding, Defense, Events, EWI – Company, Materials Engineering. 3 Comments

We just finished celebrating National Engineer’s Week 2013 here at EWI. After all, our engineers are our products, and their knowledge and abilities are great reasons to celebrate. Our Staff Association did a great job of putting together a fun week of activities to celebrate our engineers. On Monday we had Chris Cakes come toRead more

Ultrasonic Metal Welding for Lithium-Ion Battery Cells

By Steve Massey on Thursday, January 17th, 2013 in Advanced Energy, Aerospace, Automotive, Consumer Electronics, Defense, Government, Materials Engineering, Ultrasonic Processes. 3 Comments

The three most common metal to metal joints in a lithium-ion battery pack are foil to tab, tab to tab, and tab to bus. All three joints pose joining challenges, but of the three, welding multiple layers of foil to a tab is the most challenging. The joint is often made up of dissimilar metals,Read more

Welding Automation for Heavy Fabrication

By Steve Massey on Tuesday, January 15th, 2013 in Advanced Automation, Arc Welding, Automotive, Defense, Government, Heavy Industry. No Comments

More and more, robotic welding is becoming a viable option for use in heavy fabrication. The sophistication and capacity of modern robot systems is suitable for large structures which require multi-pass welds. Processes used for heavy fabrication such as preheating, gas metal arc welding (GMAW), flux cored arc welding (FCAW), tandem gas metal arc weldingRead more

Arc Welding Aluminum at High Speed

By Steve Massey on Tuesday, December 11th, 2012 in Advanced Energy, Aerospace, Arc Welding, Automotive, Consumer Electronics, Defense, Government, Heavy Industry. No Comments

Gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) are both regularly used for welding aluminum. GTAW is a slow process when compared to GMAW and GMAW is typically used when extremely high weld quality (with respect to porosity) is not required. GMAW works well for welding aluminum in structural, automotive, or thickRead more
