Which nondestructive checking method is commonly employed to verify swaged-type terminal installation on control cables?

• A. Ultrasonic testing
• B. Use of a terminal gauge to check the diameter of the swaged portion
• C. Magnetic particle inspection
• D. Radiographic testing

Answer: (B)

The use of a terminal gauge to check the diameter of the swaged portion is a commonly employed nondestructive checking method specifically for verifying swaged-type terminal installations on control cables. This method involves measuring the dimensions of the swaged terminal to ensure that it meets the required specifications for safety and performance. Swaging is a process that involves deforming the terminal around the cable, and an incorrect dimension could indicate an improper installation or a failure that could lead to cable failure. By using a terminal gauge, technicians can quickly and accurately assess whether the swaging has produced the right diameter, confirming that the installation has been done correctly and that the terminal will perform safely under stress. Other methods like ultrasonic testing, magnetic particle inspection, and radiographic testing are generally used for different applications and materials, making them less suitable for evaluating the specific characteristics of swaged terminals in control cables. Therefore, the terminal gauge method is favored in this scenario for its precision and relevance to the task at hand.
