My step son is considering joining the USAF in the Aircraft Metals Technology (AFSC 2A7X1)?

We are looking for anyone with recent experience (within 5 years or less) as a Metal Techs that can tell us what the job really does on a day to day basis. The local recruiter had zero idea about the job and the “official” descriptions are not always (if ever) aligned with the reality on the ground. He is interested in welding and fabrication type work and has a couple of years of high schools welding. Also has achieved his 1G cert, working on his 3G cert. Thanks in advance for any info.
