Daniel Dorriety
My name is Daniel Dorriety. I am a fabricator slash welder by trade. I worked for General Electric. I’ve been there for 24 years. Prior to that, I worked in some other Welding Fab [Fabrication] shops. But G.E. has been the most of my career.
Haley Hansen
You said you’d been working there for 24 years?
Daniel Dorriety
Yes, ma’am.
Haley Hansen
Can you walk me through like a typical workday?
Daniel Dorriety
Sure. So, we build gas turbines. At Greenville, I work for the repair engineering side. I am part of the special process team for repair engineering. So I focused on the joining development, which means all the parts on the gas turbine that get fixed; I handled the development of the welding, the braising, and the laser cladding repair of these parts. I have, typically, a dozen projects at a time that I work intermittently between each other. Today was more admin, catching up on documentation, more than anything. I kind of plan that out, because I’m on vacation in the next two weeks. Typically, my role specifically now is for laser repair. So, I run a C.N.C.[Computer Numerical Control] laser clatter; I do 3D Adaptive repair of gas turbine components that are by definition, unweldable. Hence why we’re using a laser. This is a fairly new change for me; that’s something I picked up about two… two years ago. The 22 years prior was all welding and brazing, and then, welding on gas turbine parts my entire stance; we did new mate manufacturing the first few years I was there, and then I switched to repair. So, I’ve been repairing and refurbishing gas turbine parts for nearly 20 years now.
Haley Hansen
For someone who doesn’t know anything about the industry, can you elaborate on the difference between welding and laser repair?
Daniel Dorriety
Sure. So, welding is it’s a manual process, and you’re using just a welding machine, and has a lot of human interface. So it’s, it’s a lot of variability between operators, not all welders are the same, right? So, it’s hard to establish control critical guidelines, you know, if you have to have a very stable process, it’s hard to control that when you have the human factor involved. And gas turbines are made of components that are very difficult to weld. By nature, they are super strong, and they hold up the very high temperatures in the engine. And that equates to alloys that don’t like to be welded. So they’re in a nutshell, very brittle and a crack. So, the difference between manual welding and laser is that laser is a more controlled process. It’s a C.N.C.[Computer Numerical Control] process that has a program driving it, right? So, you can control your heat input, your travel speed, the amount of filler that’s added, you can control all those precisely, and the density of a laser is so much more precise that your heat affected zone is smaller, which just means that you’re not going to introduce stress and cracking into the base metal nearly as much as you would with a manual welding process. Plus, it’s faster. And it’s an automated process, right? So, you can control it. You can’t weld everything with a laser, but we try to focus on the parts that are the most critical. Everything else, is pretty much a manual repair from that point.
Haley Hansen
How did you end up in the field that you’re working in, right now?
Daniel Dorriety
I always had a passion for welding. I went to Career Center in high school, took some welding classes, and loved it. I’ve always been the kind of person who likes to work with his hands. So, I knew that’s what I wanted to do. I like to build things. The fabrication side is not just welding, but it’s building structures. It’s, you know, whether you’re building a trailer or building a house. I’m building my second house now, and I’m doing all the work myself, right? I just liked that work with your hands and have something to see when you’re all done. Welding was something that I was good at it. I was always kind of into art. When I was young, I did a lot of drawing. And I think that helps me with welding.
Daniel Dorriety
You know, it’s a lot of hand-eye coordination, just fell in love with it. I stuck with it. And this is where I’ve ended up.
Haley Hansen
Being able to like to visualize the finished product I imagined helps a lot.
Daniel Dorriety
Especially on the artistic side. Yes. You know, typically, in my field, they give you a drawing, and you have to make it, right? So, there’s not a lot of visualization in that. But outside of G.E., I know I do gifts for people. I do fire pits. I built fire pits and that’s where the vision comes in, right? You have to have an idea in your head and then create it.
Haley Hansen
Did you, go straight into professional welding right out of the career center and like high school?
Daniel Dorriety
Pretty much. Yeah, I started in a [work] Co-oping in my senior year of high school. That would be my second year at the Career Center. So, instead of going to class my senior year, I went straight to work, Co-op, and then, when I graduated, I was hired full-time into the company I was working for welding, and then I continued on at Tech[Horry Georgetown Technical College] and got my associate’s degree. Then, eventually, I switched over to General Electric and have been there ever since.
Haley Hansen
What was your associate’s degree in?
Daniel Dorriety
Industrial Technology, with a major in Welding.
Haley Hansen
Do you have, like, a defining moment in your career or your creative journey where you realized, like, that was what you wanted to do for the rest of your life?
Daniel Dorriety
I guess the only thing I can really remember, is that my uncle had a fabrication shop. He built trailers. I found that fascinating when I was young; pretty young. I was probably in middle school, and I would go over to his shop and see what he was building and see all his tools. I just thought that was fascinating. And I wanted that for myself. And I think that’s how I kind of went down this road. 30 years later, I now have my own shop, and I’m starting to do stuff freelance on the side with a goal of eventually being self-employed, but G.E. is a pretty good job. So, I’m gonna stay there for a while.
Haley Hansen
I’m sure they’re glad to hear it. [Dorriety laughs] What would you say was the biggest adjustment or challenge you faced when you started your current role?
Daniel Dorriety
Maybe working with people? You know, all the different kinds of personalities.
Haley Hansen
That would do it.
Daniel Dorriety
You know, being a welder, especially the first place I worked at, you kind of got a rough crowd. I worked with a lot of field hands, guys that are used to working on the road and a lot of different personalities. And then, switching over to GE, a much more professional environment. So, that was definitely better. And then migrating into working for repair engineering, where I’m working with all very professional people, you know, that are engineers, and PhDs, and again, very different personalities, right? So, it’s learning how to fit in the world from one extreme to the other.
Daniel Dorriety
So, one of my primary jobs is, developing a repair but also transferring that repair to the shop so that they can do the repair. And then I have to train the operators, right? So, I’m the interface between the operator on the floor doing the work, the engineering staff that controls the process, and then our engineering staff that owns the process, right? So, it’s working with a vast difference in personalities is probably the biggest challenge. And we’re global too. So, we work with people in Singapore; we work with pink people in Saudi Arabia, shops all over the place, language barriers, and cultural differences. So, I’d say people. People are the biggest challenge.
Haley Hansen
Kind of related to that, can you recommend any specific skills that someone aspiring to your profession should develop?
Daniel Dorriety
Practice. It goes just along with everything, you know, if playing a guitar, for instance, I can’t play but I imagined that the more you do, the more you try, the better you get. And the same things for welding; I mean, you’re not going to grow and have better opportunities. If you don’t try be the best you can at it, right? You’ve got to put in the time, and you got to put the effort in; it takes a lot of practice to get good at welding; it’s not something you can just learn in three weeks; it literally takes months to years to get proficient, much less expertise. If somebody chooses to be a welder, I’d say that patience and practice. And a lot of it.
Haley Hansen
Are there any organizations or programs, or maybe, like, annual events that you would recommend for folks who are interested in your field, in South Carolina?
Daniel Dorriety
Well, the tech centers are bringing back trade schools. I went to Greenville Tech, their program was pretty decent. There is a private organization called ArtLabs that has a more intense and faster program that’s more specific to getting people employed and getting into work faster, versus going to Tech[Horry Georgetown Technical College], that kind of, kind of drags things out because they want to add extra classes to your workload and things that don’t get you into a job shop faster, right? So, I would probably lean towards art labs, they come with a very good reputation for their program. You know, other than that, working with people, making connections with experienced people, I’ve had a lot of people come up to my place that wants me to do things for them, and that are fascinated, and they want to watch and they want to learn and then they come back and I help them. Not necessarily a school, but this kind of gets them started just enough, where, they can do things at their house, and they can practice.
Haley Hansen
Do you have any advice for current students or young adults who are pursuing a creative career in welding?
Daniel Dorriety
Just don’t be afraid to try. Don’t let the fear of the unknown hold you back, I think I would have probably been freelance much earlier. If while, one, I had a family, so I had to have a steady income and benefits. So, that kind of helped me where I was. Still, the fear of the unknown kind of holds me back because I do have a stable good job. And I hate to walk away from that and struggle, right? So, I’ve been trying to build my own thing on the side.
Daniel Dorriety
In addition to keeping my stable pay slash benefits, who knew the day I enjoy making things? I do a lot of retirement gifts for people at G.E. I’ve probably made 30, 40, 50 of them over the years. Some of them have turned out really good, very artistic. Some of them are okay, but in the day, it’s fun. But I’m afraid if I get in a position to where it’s a consignment job, or I have to do it to make a living, that the fun will disappear.
Haley Hansen
Oh, I know that feeling.
Daniel Dorriety
Yeah. So, I don’t want to get in that position to where I don’t enjoy it, right? So, I don’t know. It’s the fear of the unknown that still gets me. I don’t know how to compress that yet. Small doses I guess.
Haley Hansen
Before we end, is there anything else you think is important that you say here?
Daniel Dorriety
Just, I always told my daughter that if you can find something that you enjoy… that you can make money at it. Then you never really have to work for a living. I never quite figured that out for myself, but I hope she does. So, just try to follow your passion and make some money at the same time.
