In the assembly workshop, the blue light shot, and the welding flower splashed. A female electric welder wore a helmet, goggles, masks, and a thick workwear. On the six -foot -high workbench, she welded the middle beam of the railway truck skillfully.

She is Yi Ran, a senior technician of the Welding Welding of CITIC Changjiang Group Zhuzhou Vehicle Co., Ltd.

The hot sun, the temperature in the workshop is as high as 45 ° C. There are no air -conditioning or fans on the workbench, and the work clothes have long been soaked by sweat. Douda's sweat bead slid into his eyes from his forehead, Yi Ran put down the welding gun, wiped the sweat beads, and continued to work.

"This is gas protection welding, which cannot be blowing, otherwise it will affect the process." Yi Ran told reporters that some special materials need to be heated to 150 ° C to 250 ° C before welding. In order to complete the task on time, electric welders can only welcome the "fire".

The middle beam on the railway truck carries the weight of the whole car. The abdomen is an important part of the middle beam, and has the highest level of quality requirements for welding. Yi Ran dare not have the slightest care: "The abdomen of the railway truck should be welded together with 12 mm and 6 mm thick, respectively. Waiting for defects. "

In the summer of 2000, 18 -year -old Yi Ran graduated from Wuchang Technical School and was assigned to CRRC Changjiang Group Zhuzhou Vehicle Co., Ltd. to assemble the bottom of the assembly workshop.

For the first time on the six -foot -high turning platform, I saw 12 welding machines lined up. The 12 clusters of welding flowers fell one after another. The scene was fascinated and I felt pressure: "In school, I have only learned to welded, and I have never tried this semi -automatic gas protection welding."

With hard work and understanding, Yi Ran quickly applied the foothold with the largest welding volume and the most difficult working conditions in the workshop. work.

In just 3 years, Yi Ran completed the leap from "technical bronze star" to "technical Venus". It is the shortest employee who has set up the award for more than 20 years. In July 2005, 23 -year -old Yi Ran was successfully admitted to the group company technician qualifications with computer drawing first, implementation first, and second theory of more than 20 players, becoming the youngest of Zhuzhou Vehicle Co., Ltd. technician.

In 2007, the company's export orders increased, and Yi Ran was transferred to the new product trial class of assembly workshops. The trial production of product vehicles not only mastered the international general welding standards, but also became a highly praised "international welding worker", and has explored a series of international advanced welding techniques.

In 2007, the company exported railway trucks to Australia for the first time. The car is advanced in the world, and the technical standards adopt the European standard far exceeding the AAR standards. Yi Ran is responsible for the beam welding in the core component. The Australian monitoring experts demanded that the bite of all welded seams of the middle beam welded in the Macau is zero.

"Such accurate manual operations are equivalent to the fine standards of CNC robotics." During the one -and -a -half -month trial period, Yi Ran and another welding technician guarded the front line day and night. "At first we can't do it, we always need to keep working." In the aspects of the options of welding equipment, optimization of welding parameters, debugging of workstarial membranes, and breakthroughs in traditional operation methods, Yi Ran repeatedly tested and colleagues repeatedly tested the test , In the end, success.

"I created a new skill of filled the arc pits on the spot, and welded the first high -quality middle beam. Usually, the cold -frosty Australian supervisory expert was very satisfied and gave me a thumbs up." Yi Ran said, "I am the happiest It is not to create new skills, but to show the quality of Chinese workers and make 'Made in China' well -known world. "

Over the past 22 years, Yi Ran has completed more than 80,000 new vehicles and delivery of new railway trucks. She led the team to participate in the company's welding research projects of more than 100 items, more than 60 new material welding process and process assessment tests, completed 47 technological innovation of heavy -duty high -speed railway trucks, and applied for 33 national patents. In 2015, Yi Ran was rated as a model for labor, and was selected as the "China Good Man List" in December 2018.

"It is said that the hard welding is hard, young people are unwilling to work, and it is not suitable for girls. But I want to say that there are difficulties in traveling, but they have their own fun and value. Blooming and gorgeous life, adding color to the motherland in the struggle. "Yi Ran said.
