Welding Engineering senior Jacob spent his summer at an internship with a medical device company.  Here is his report.

Greatbatch MedicalOver the summer of 2013, I participated in a welding engineering internship program in Buffalo, New York, with Greatbatch Medical.  The scope of products there range from batteries used in medical devices, drilling rigs, in NASA designs, to catheters and orthopedic implants. In the Buffalo facilities, batteries, capacitors, medical devices, and feedthroughs are the main focus.

Welding processes incorporated here are ultrasonic, laser, and small scale resistance welding.  Additionally, some brazing has been applied to certain projects.  Materials used in the various products include titanium, molybdenum, aluminum, stainless steel, nickel, platinum, gold, and lithium.

For my major project I was able to work on a scanning electron microscope (SEM) for microstructure analysis and composition mapping.  I found the exposure to these exotic materials and complex processes very interesting.  My co-workers were both knowledgeable and very friendly, helping me through whatever was necessary in my projects.

 

Senior students in the Ohio State Welding Engineering program are required to finish their year with a year-long senior capstone project.  The projects are usually done in teams, with the support from companies such as John Deere, Lincoln Electric, Caterpiller, General Electric, etc.   Here, seniors Dorian, Brian, and Paul show their advisor how a small robot welder works.

Paul explains:

We are studying the effects of shielding gas combinations on the weld properties.  We are testing four different gases, each primarily argon mixed with different levels of carbon dioxide or oxygen.

There are two different types of metal and three thicknesses of each steel being tested.  The main goal is to find the shielding gas combination that gives the best properties of the weld.

The use of a robot is essential in creating consistent welds and eliminating human error.

As seen in the video, a simple horizontal fillet weld is being made.  The testing with the robot just began and the exact parameters aren’t dialed in yet, which can be seen/heard in the video.  The robot is an education robot cell from Lincoln Electric and is very useful for small scale testing such as what we’re doing or for learning robotic welding in classrooms.


Hi, my name is Lucas Crumley, and I’m a 4th year student in Welding Engineering.

Instead of talking about my classes, I want to tell you about my job as an Engineering Ambassador. As an ambassador, I give tours to prospective high school students, but instead of covering all of campus like the University Ambassadors, I get to focus on the best part of campus: the College of Engineering!

On my tours, I show students some of the labs and classrooms that Engineering students at Ohio State typically use in their first year. I also talk about my specific experiences in classes, dealing with professors, campus life, and how and why I ended up coming to Ohio State, studying Welding Engineering.

Each ambassador is required to be able to talk about all of the Engineering Majors offered at Ohio State, but we have the freedom to promote our own majors specifically.

If you are a prospective high school student, I highly encourage you to take one of our tours because you not only get to learn about why Ohio State is an AWESOME university to attend, you get to hear our stories, experiences, and tips while seeing all that the College of Engineering has to offer.

So if you do come for a visit and attend our college overview and tour, you might get the joy of having Kristen Hammer, the only other Welding Engineering major Ambassador, or me as your tour guide – especially if you say that you want to study Welding Engineering.
