Airman 1st Class Jeremy Halcomb, 60th Maintenance Squadron Aircraft Structural Welding shop metals technologist, uses a mig welder Sept. 15, 2014, for the finishing touches on the frame of a training obstacle that will go to the 60th Security Forces Squadron Military Working Dog canines at Travis Air Force Base, California. The MWD unit saved nearly $30,000 by using the Airmen welders to fabricate the frame instead of purchasing from a contractor. (U.S. Air Force photo/Senior Airman Madelyn Brown)
