(Go to the grassroots in the New Year) The last Spring Festival travel of Guangxi train "detective": tiny cracks cannot escape his hands
Chinanews.com, Liuzhou, January 16th, title: The last Spring Festival travel of Guangxi train "detective": tiny cracks cannot escape his hands
Author Liu Juncong
On the 15th, in the bogie workshop of Liuzhou Locomotive and Rolling Stock Co., Ltd., 59-year-old Xiao Guangxin held an ultrasonic probe to detect a wheel set of a railway vehicle.
As the arm moved repeatedly, the ultrasonic pattern on the computer screen kept beating, and he stared at every change calmly.
"The abnormal ripples are fleeting, and there is often a tiny crack behind them. We have to maintain a high degree of concentration, staring at the screen for a long time every day, and 'dealing' with these silent ripples." Xiao Guangxin said.

The wheel set of railway vehicles is a key part of the operation of railway passenger and freight vehicles. During the manufacturing process, there may be defects and cracks that cannot be detected by the naked eye. It is necessary for flaw detection technicians to use ultrasonic flaw detection equipment to detect and detect them according to the size and shape of the reflected waves.
Xiao Guangxin is a flaw detection technician for passenger and freight wheels in the company. He is tall and thin and has been engaged in flaw detection work for more than 30 years. He has never had a wrong or missed detection accident.
Xiao Guangxin is often affectionately called the train "detective" by his colleagues because he can always accurately find the "clues" of cracks in various parts of the wheel set.
"Cracks in the wheelsets of railway vehicles are not a small problem. Even a crack of 0.1mm may cause a broken axle when the train is running at high speed, resulting in irreparable consequences." Xiao Guangxin said.

Xiao Guangxin once served as a hygienist in the army and saved many wounded soldiers from death. In 1984, after retiring from the army, he worked hard to become a train flaw detection technician in the company.
Xiao Guangxin, who has experienced two "life-related" jobs, has a deep understanding of the sense of responsibility for life.
"We overhaul more than 60 pairs of railway vehicle wheels every day, and the probability of cracks in the wheel set workpiece is only a few ten thousandths." Xiao Guangxin said.

Although Xiao Guangxin has been engaged in flaw detection for decades and has a lot of experience, he still firmly believes that the probability of this happening is one in ten thousand. Once his keen eyes catch the abnormal ripple, this wheel set will be re-detected by him again and again. If there is another exception, it will be returned directly for processing.
"This work cannot be done based on experience alone. Now that the speed of trains is getting faster and faster, working condition problems that would not have occurred before may occur now, and there should be no fluke mentality." Xiao Guangxin said.
Over the past 30 years, through flaw detection, Xiao Guangxin has killed countless potential safety hazards in the cradle.
Today, Xiao Guangxin is about to retire with honor, and this year is the last Spring Festival he will protect.
"Seeing that everyone can go home safely for the New Year, although our work is dull and boring, it is also very meaningful." Xiao Guangxin said.
