The parts were marked using a 20 Watt Pulsed Fiber Laser using a 160 mm lens. The 3 small samples were annealed to create bright contrasting marks with the power of 12 Watts, frequency of 35 kHz, and speed of 4" per second. The gauges were etched using 12 Watts of power, frequency of 35kHz, and speed of 15" per second. The big gauge was lightly etched resulting in shorter cycle time of 1.14 second comparing to the small gauge cycle time of 2.23 seconds.
