Last winter the department received an email from Kristen, a 2012 Welding Engineering alumna working at SpaceX, who wanted to know if there were any Welding Engineering juniors interested in doing their summer internship in California and working on some projects with her and with Jon, another OSU WeldEng alumnus.  It didn’t take long for Bob to submit his application and get hired for the gig.   Here is an update on his experiences so far.

It is extremely exciting to work for a company like SpaceX that is at the forefront of commercial space flight, and that has tremendous goals like colonizing Mars.  SpaceX has high expectations of its interns, so I get to do worthwhile work that will benefit me greatly in my career. Also, SpaceX uses technologies and materials that are at the cutting edge of industry. I get to work with processes like electron beam welding, friction stir welding, robotic tig and mig welding, as well as with materials like titanium, Ni-based alloys, and niobium alloys. It’s an opportunity I wouldn’t have had at another internship.

SpaceX is trying to increase production so they can increase the number of launches per year.  In order to do that the manufacturing processes have to be made more efficient, and welding is a huge part of the manufacturing.  If you need a welding engineer you come to OSU.  Two of the engineers working on welding here are Kristen and Jon, both OSU WE alums.  When they needed an intern, Kristen contacted OSU to find one, and I guess I qualified and did enough to convince them that I could do the job.

A number of my Welding Engineering courses directly relate to what I am doing at SpaceX.  Some of my responsibilities include qualifying welding procedures, so I do some metallurgy work which we learned about in the Materials and Processing Lab. The Welding Engineering Design courses addressed maximum allowable heat inputs allowed, as well as the codes necessary to understand what is required in a Welding Procedure Specification and supporting Procedure Qualification Records.  Other classes have aided in my understanding of how to evaluate a weld procedure and to improve upon it.  I’ve had to teach myself a lot of what will go on in Welding Metallugy II, but Dr.  Lippold’s stainless steel and Nickel-based alloy text books have come in very handy.

Solid State Welding Demo

Throughout the summer high school students in various camps will visit Ohio State’s College of Engineering to learn about the different engineering majors offered.  Today, a group of rising high school sophomores and juniors learned about Welding Engineering and Materials Science and Engineering.

Here, a Welding Engineering student uses a drill to weld an aluminum bit to a larger piece of aluminum. This use of friction to weld metals is a type of  “solid state welding.”
