Description

  1. TASK 70-26-00-260-501 General Instructions On X-ray Inspection Procedures

    WARNING

    RADIATION IS VERY DANGEROUS TO PERSONS. YOU MUST MAKE SURE THAT ALL SAFETY PRECAUTIONS AND INSTRUCTIONS, BOTH NATIONAL AND LOCAL, ARE OBEYED. THE MAXIMUM DOSAGES FOR PERSONS MUST NOT BE MORE THAN THE SPECIFIED LIMITS.

    WARNING

    YOU MUST NOT GO INTO AN AREA WHEN X-RAY EQUIPMENT IS IN OPERATION. PERSONS WHO ARE NOT APPROVED MUST NOT GO INTO AREAS WHERE X-RAY EQUIPMENT IS USED.

    WARNING

    ALL SAFETY DEVICES MUST BE EXAMINED BEFORE THEY ARE USED. THIS INCLUDES DOOR INTERLOCKS AND AUDIBLE AND VISUAL WARNING DEVICES.

    1. General

      1. Radiological inspection with X-rays is a non-destructive inspection procedure to find defects (Such as cracks, inclusions and porosity), on and below the surface of parts. The procedure can be used on parts made of metal and other materials.

      2. The radiological inspection procedure to be used must always be fully specified in the related instructions.

      3. The radiologist who prepares and applies the inspection procedure and the person who examines the radiographs must be fully approved for the type of work to be done.

      4. Non-film radiographic techniques: The use of non-film radiographic techniques is permitted, provided the method used is sufficiently sensitive to resolve the required quality level. A detailed inspection must be provided, correlated to the film technique.

    2. Safety Precautions

    3. Preparation of the Parts

      1. To get the best results, the area to be radiographed must be clean and dry. There must be no oil, grease or unwanted material, such as a weld underbead.

      2. When possible, a weld underbead must always be machined smooth and level with the base metal. But, in general, this is not possible with assemblies made from a sheet material. There must be no unwanted material on the two surfaces of a joint; because it can damage the radiograph, or cause an incorrect indication to be made.
