Today at BTEC I started of I helped one of the employees to get equipment to some people working for BTEC in the field at a Railroad yard and was taught another testing methods that BTEC uses, Magnetic. MT (Magnetic Testing) uses a magnetic powder to spray onto a piece of metal where there is most likely wear on metal, then they use a strong magnet against the metal. The powder reacts to the magnet in such a way that the powder will reside in even the most microscopic cracks making them visible to the naked eye. MT doesn't test the metal's wear rate or how much of the metal has been worn down to certain inch like UT (Ultrasonic Testing) it only finds surface cracks in the metal. After that I helped my mentor take a tire off of a skid steer for repairs. For the remainder of the day I was introduced to Autocad a little more. Not only was learning about autocad and how incredible it is I was literally drawing, labeling, and doing the whole process of actual pipe at an actual facility in Texas.
