Are there any operating procedures for flaw detection?

operating rules of nondestructive flaw detector (1) ultrasonic flaw detection 1. before using the instrument, the wires, plugs and other related equipment and tools must be inspected, and they can be used only after passing the inspection. The instrument must have a reliable grounding wire. 2. The power supply of acoustic emission flaw detector should use rubber cord or light mobile cable. 3. In the workshop where flaw detection is often needed, a standby fixed power supply should be installed near the switchboard, and the flaw detector shall not be arbitrarily connected. 4. When working in the workshop, there must be more than two people working at the same time. 5. When working at heights, safety protection measures should be provided to prevent people and instruments from falling from heights. 6. The local lighting voltage in the workplace must be safe voltage below 36V. (2) Magnetic flaw detection 1. Before operation, carefully check the contact and insulation of electrical equipment components and power supply wires, and confirm that they are in good condition before operation. 2. The room should be kept dry and clean, and the bolts connecting wires and conductive plates must be solid and reliable. 3. When clamping or taking down parts between electrode tips, the power must be cut off and the parts must be fastened. 4. When charging and magnetizing, the power supply is not allowed to exceed the allowable load. When doing the above work or opening and closing the main power switch, the operator should stand on the insulating mat. (3) fluorescent penetrant inspection 1. The operator wears a mask and turns on the ventilation equipment. Dangerous goods in the fluorescent room should be properly stored, and fireworks are strictly prohibited. 2. Spray the mixed solution of magnesium oxide powder and alcohol or inspect the parts under ultraviolet light. Protective equipment should be used correctly. Paint should be sealed and kept in storage. When working, the exhaust equipment should be turned on. 3. Don't eat and drink in the operating room. Wear protective glasses when working under ultraviolet light. 4. After the work is finished, the liquid tank must be tightly covered and locked, cut off the power supply, clean up the site and close the doors and windows. (4) X-ray flaw detection 1. Before taking pictures, first turn on the cooling water and check whether the water flow meets the performance requirements of the X-ray machine. 2. Turn on the main power supply, check the rotation of cooling water and oil pump electrodes, turn off the power supply in time when problems are found, and notify the maintenance personnel for timely maintenance. 3. It is forbidden to stay indoors when taking pictures. Protective fences should be set up outdoors, and there should be enough protective distance when working outdoors. Hang a warning sign, and no one is allowed to pass. 4. When controlling the exposure conditions of the X-ray machine, the equipment operation procedures must be strictly observed. 5. After the filming, the cooling water and oil pump should continue to run for 1 ~ 15 min before cutting off the power supply. 6. In the photo studio with an electric turning table indoors, be sure to pay attention to whether there is power and wires on the track before the battery car starts. 7. When washing the room with water, do not spray it on the electrical appliances. 8. Always check whether the grounding and zero connection of the equipment are normal, and wear pressure rubber shoes when operating. 9. When filming, you must turn on the power supply of the fan to ensure smooth air flow. 1. The protection of X-ray flaw detection room must be approved by relevant departments before it can be put into work. The protection of flaw detection room must ensure that the direct penetration of rays and scattered rays cannot exceed the allowable amount of safe measurement of rays. Ozone produced by ionization in flaw detection room must be discharged to places where no one works and lives. 11. Staff should have regular physical examination (usually 6 months). 12. Other relevant matters shall comply with the relevant provisions of the safety technical operation procedures for radioactive workers.
