Airman 1st Class Joshua Soucy, 28th Maintenance Squadron aircraft metals technician, welds metal sheets together at the welding shop on Ellsworth Air Force Base, S.D., Aug. 15, 2013. When the sheets crack, they are welded back together to ensure their structural integrity, which also prevents the Air Force from having to buy an entirely new part.
