My name is Connor, and I have been working as an intern in the Welding Engineering department at The Ohio State University this summer. I am currently a student at Metro Early College High School.

During the school year, I had an internship at Battelle under a Materials Engineer/Tribologist there, Dr. Merriman, and he was the one who originally got me interested in Materials and Welding Engineering — before him, I didn’t even know it was a field of engineering. I then found out about the internship opportunity the Welding Engineering department offered through my FIRST Robotics Team’s Coach, Dr. Bruening. I was very interested because I had previously been exposed to this field of engineering.

After some interviewing, I got the position and started working under two graduate research associates, Jansen Lenzo and Michael Orr. I have been studying solidification cracking in nickel and cobalt based alloys in addition to high manganese steel. Day to day I bounce between preparing metal samples, working with microscopes, compiling data and observations, and studying/discussing welding engineering concepts. Before this internship, I was dead set on doing Aerospace Engineering, because for the last two years I have been the Lead Designer/CAD Guru on my Robotics Team. But, welding engineering has proven to be a grand slam of every field of science I have come to enjoy.

I really love my job, the community at the welding engineering department is fantastic and the experience and information I have gathered here is invaluable. Michael and Jansen are real all-star mentors and it has been awesome to have two people so dedicated to promoting my ambitions and accelerating my career. I would recommend this opportunity to any other young engineer.

Go Buckeyes!



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.

 

If the bachelor’s degree isn’t enough, there also are the master’s and PhD programs in Welding Engineering.


Summer internship update from OSU Welding Engineering senior Dorian M.

Southwest Research Institute

I have been working in San Antonio TX for Southwest Research Institute (SwRI) in the Mechanical Engineering Division. Within that division I work in the department of Sensor Systems and Nondestructive Evaluation Technology. My  work in ultrasonic testing is in two technologies: EMAT (Electromagnetic Acoustic Transducer) technology, and Magnetostrictive Sensor Technology.

I’ve been working on developing methods of permanently joining the magnetostrictive “transducer” to heavy pipe and plate for long-term structural health monitoring while in-service at temperatures above 500F. The magnetostrictive material I have been working with is a thin strip of an Iron-Cobalt alloy that is extremely difficult to join.

Currently I have developed procedures and methods for soldering, brazing, and adhesive bonding without affecting the magnetostrictive properties of the FeCo alloy.  Based on my research here I was asked to give a seminar to the Mechanical Engineering Division on soldering, brazing, and adhesive bonding of this alloy for use in non-destructive testing.


Ben

Working as a lab assistant has enabled me to be exposed to a number of projects that I otherwise would not have had the chance to be involved with. Along with valuable work experience, the exposure to these projects has also provided useful knowledge for my coursework. I plan to finish my BS in Welding Engineering in the spring of 2011 and would like to attend graduate school soon after.

Daniel

As a freshman I enrolled in the College of Engineering undecided on a discipline, however, by the end of the year I had chosen Welding Engineering as my major.

In Summer 2009, I completed an internship with Trinity Marine Products, Inc., a barge-building plant located in Ashland City, Tennessee. During my internship I worked to help reduce the amount of welding required to construct the barges, resulting in very large annual savings.

Adam

I am currently a senior at OSU, and plan to graduate in 2010. In spring of 2008 I started working with the Welding and Joining Metallurgy Group.   I have done a lot of work with nickel-base alloys, determining solidification cracking susceptibility of various alloys.
