Some people can weld the steel plate as thin as kraft paper without any leakage, and some people can control the sealing accuracy to one fiftieth of the hair of the head. This is not the magical power in fairy tales, but the most common work experience of Gao Fenglin, a senior technician in the rocket assembly plant of the First Academy of China Aerospace Science and Technology Corporation. He drew a rocket welding heart, and was the first person to think of welding. 0. 16 mm, which is the width of a solder joint on the rocket engine; 0. 1 sec is the allowable time error of welding. No matter how many times I watch such a difficult welding skill, I can't help but sigh whether it is skill or art, skill and art, spirit and work, and sometimes it is in such years that it is carved into the acme of beauty and * * *.
Li Wanjun: His "one gun, three welds" po solved ZTE's "leg and foot" problem, and a welding torch created China's speed. Participated in the trial welding of dozens of domestic urban rail vehicles and EMU bogies, summarized and formulated more than 30 kinds of bogie welding specifications and operation measures, and tackled more than 50 technical problems, of which 27 were granted national patents. More than 30 bogie welding operation measures, such as his "right-hand welding method", have saved funds and created costs of more than 80 million yuan for enterprises.
Wang Shujun, an ordinary maintenance worker, broke into the forbidden zone of foreign high-tech equipment maintenance, broke through the technical blockade, bravely reformed the design defects of the core components of imported production lines, and produced a high-power and low-energy-consumption engine independently developed by China, which made China stand on the same level as the world's top players in the field of heavy-duty diesel engines. He is a maintenance worker and a designer, more like a soldier who will never obey! Begging for mercy in times of crisis is only for the sake of the country's heavy weapon and cannot be controlled by others. He vividly described the character of craftsmen in China.
Chen, 29, told us that a person's greatest pride is that the world doesn't have to know who I am, but what I do surprises the world. The national defense industry represents the highest level of manufacturing in a country. The craftsman in it has to hit the limit of his skills countless times. In the field of new numerical control machining, Chen Hangxing always turns possibility into energy. This is another extreme challenge. Thin shells will be used in cutting-edge weapons and equipment, and the 50% pass rate is always insurmountable in China. To this end, Chen revised the programming, adjusted the tool, sorted out the parameters, changed the tool path and clamping method countless times. His efforts finally made the product pass rate reach 100%.
Looking back on 20 18, China has contributed too many outstanding achievements and miracles to the world. In this area, the Hong Kong-Zhuhai-Macao Bridge is undoubtedly the most brilliant one. It is the longest sea-crossing bridge in the world at present. Known as the bridge world's Mount Everest, the Great Wall on Water. Its construction period is 15, creating the best of seven worlds. The Hong Kong-Zhuhai-Macao Bridge is one of the seven wonders of the new world. Behind this world-shaking project, the wisdom of more than 30,000 China supporters has been gathered to tackle key problems collectively. Maybe we can't remember everyone's face, but they have a resounding name-China craftsman!
Touching stories of great country craftsmen and vivid practical notes, only those who love their jobs, are down-to-earth, diligent and hard-working, can achieve a career and expect to expand the cost of life. As a railway supporter, I deeply realize that I should give full play to this craftsman spirit in my post, and I should pass it on.
