I Think About This Stuff All The Time

By Kirk Cooper on Tuesday, November 1st, 2011

The joint design for a particularly challenging project had been on my mind for several days.  Joining metals and ceramics is almost always a dicey business, but when the components are large cylinders with joint integrity requirements that mirror those of an implanted medical device, it can be daunting.  I had sketched out several options, taking into account the various joining approaches we had considered and the huge difference in thermal expansion coefficients that could tear the assembly apart.  Each approach seemed to have a fatal flaw.

Now, lying in bed, I awoke with a fresh idea that seemed to address all the challenges. I rolled over and glanced at the clock; it was 4:07 am.  My alarm would go off in an hour, but my mind was already 100% awake and churning away with details of the joint and the process we would need to make it.


I would like to say this is an uncommon occurrence for me, but it isn’t.  I also suspect that I’m not the only one here that has these early morning brainstorming sessions for our clients.  Are we crazy?  Perhaps.  But bring one of your particularly vexing materials or joining challenges to EWI and you can rest easy, knowing that you may be keeping some of us awake all night.
