  • Patent number: 3956694
    Abstract: A table top, table frame and tank combination. The table top has a flat topped surface made of a rectangular steel plate. Insulating bars are supported on the table top and extend radially from the center and a bar made of an electrical conductor is supported on each of the insulating members providing a space for magnetic flux to flow therebetween. The table frame is made up of four angle irons that are welded together at the corners to form a frame and an angle iron leg is attached to each corner. One leg of each angle iron lays in a common plane with one leg of each other angle iron, defining a flat surface designed to hold the different sizes of table tops in required position. A fluid tank for the purpose of containing a fluid to be pumped to the part to be inspected is supported below the frame. This apparatus can be used with any equipment of the type generally used for magnetic testing capable of producing the proper magnetizing current.
