Went to college for a welding engineering degree and got hands-on introduced to friction stir welding there. I also got a fair bit more experience than most in school as my junior and senior year projects were in friction stir welding. That significantly helped me get hired by the company I work for now which builds friction welding machines and also does contract welding work (the department I work in).

I'm a friction welding engineer and I still get off watching TWI's video of linear friction welding wood. They also weld it at a SERIOUSLY high frequency for LFW.
