Automated Inspection Systems.
The penetrant inspection process can be adapted for use with semi and fully automated processing equipment. Semi-
automated systems consist of a conveyor belt or table for moving the parts through one or more of the processing steps.
Applications of penetrant, emulsifier or remover, rinse, or developer are manually performed. In fully automated
systems, all of the processing steps are mechanically performed without an operator. Automated equipment allows
large numbers of parts to be rapidly processed with a minimum of personnel and time. Automated equipment also
provides a more uniform, though not necessarily more sensitive, testing process. The inspection interpretation can be
performed manually, semi or fully automated.
