"The heart is in one art, and its art must be worked; the heart is in one post, and its duty will be lifted." Huadian Energy Jiamusi Thermal Power Plant Steam Engine Branch Comprehensive Team Leader, Heilongjiang Province Senior Welding Chief Technician Wen Wu, since 1987 to participate in the work for 34 years, has always adhered to the power plant welding post, hard training technology, overcome difficulties, rapidly grew into a technical expert in the field of enterprise welding, many times won the Jiamusi City and Huadian Energy Company welding professional and technical experts, has won the "Jiajia Craftsman", "Huadian Energy Craftsman", "Longjiang Technical Expert" and "Longjiang Craftsman", He became the first person to obtain the title of high-skilled talent with special allowance from the State Council in the 83 years since the construction of Jiamusi Thermal Power Plant.
Diligent study and hard work, forging craftsmanship
Welders are the most ordinary craftsmen. At the beginning of the work, WenWu wore heavy canvas overalls, buttoned closed welding caps, and tempered his will with his co-workers in the smoke and fire. In order to master the excellent technology, he humbly asked the teacher for welding skills, while practicing the basic skills, taking chopsticks to practice the action of sending silk when eating, practicing stability with a tank filled with water when drinking water, holding an iron block to practice endurance when resting, from the preparation before welding, to the ratio of protective gas, debugging voltage and current, selecting welding rods and welding angles, Wenwu has been repeatedly practiced hundreds of times. The welding torch sprayed flames of several thousand degrees Celsius, instantly melting the steel. In the middle of summer, mars splashed in the workshop, the smoke was thick, the sound was harsh, and the smell was choking. Welding sparks sometimes fall from the collar to the stomach and neck, and burns are very common. At the same time, because welding requires concentrated operation, sometimes the clothes are burned, and even if it catches fire, he does not realize it. The welder is a very hard and tiring job, but Wenwu loves it and studies it. In order to deepen his memory, Wen Wu will carry a "small book" with him every day, which records every question and answer he encounters that he does not understand, as well as the welding angle, current, welding parameters, etc. during the operation, and will read and review it in his spare time in order to fully grasp it. The factory issued a set of overalls every two years, but he had to wear out more than one set a year. The masters all said that the child was persistent and asked too many questions. It is with this momentum, whether it is fire welding, electric welding, argon arc welding, or flat welding, horizontal welding, vertical welding, back welding, he has repeatedly practiced to master freely, this spirit of not afraid of hardship, not afraid of being affected, good at observation, the courage to study, so that Wenwu has accumulated energy and become a welding expert.
Engaged in welding work for more than 30 years, Wenwu has carefully welded every weld. All the dirty work in the class was tiring and hard work, drilling the hearth, drilling the gutter, climbing the toilet, and the work with water and steam was rushed to the front to do it. The cutting-edge work and key work in the factory are all looking for him, and every urgent, difficult, dangerous task, he bravely picks the beam. In the installation process of the 300MW unit, due to the high-pressure cylinder bolt locking, which seriously affected the construction progress, engaged in thermal power installation for many years, experienced teachers and masters also had no idea, and the construction unit was helpless. In times of crisis, the true colors of heroes are revealed. Wen Wu was in danger, and he used the non-destructive cutting method to solve this problem in just one day.
Overcome difficult problems and interpret the spirit of craftsmanship
Over the past 34 years, he has cultivated a strong skill with his diligence, positivity and self-confidence, and won the confidence of leaders and comrades with his love, heart, care and humility. Excellent technology and dedication to welding technology have become the whole connotation of Wenwu's "responsibility".
After years of diligent study and hard work, Wenwu has trained welding technology into a divine way. For large and thick, small and thin pipes can be welded freely, as long as the welding sound is heard, Wenwu can judge the size of the current and voltage, the width and narrowness of the weld, and the quality of the welding.
With increasing skill, he naturally embarked on the road to overcome technical problems. Factory No. 1 boiler water-cooled wall burst pipe, in order to shorten the construction period of the metal proposed the use of alkaline welding consumables welding process, which requires high welder skills, must be strictly in accordance with the welding process specifications to operate, otherwise it will not be able to ensure the performance and use requirements of the water-cooled wall pipe after welding. Faced with technical difficulties, Wen Wu gladly accepted the work, he saw the tricks, braved the high temperature, with his exquisite welding skills to complete the task overnight, the metal non-destructive testing of the welding part was fully in line with the requirements.
He loves to ponder and study, and likes to gnaw on the "hard bones" at work. Whenever he was entrusted with the work, he always racked his brains to think about how to improve the working methods, improve the accuracy of the work, and ensure the high quality of the work tasks. The sealing surface of the high-temperature and high-pressure steam valve of the No. 1 machine is corroded, and if the replacement valve production and processing cycle is long, the cost is also very high. He proposed the use of imported welding consumables D547, surface alloy surfacing treatment, valve surfacing fully meet the requirements of use. When the steam turbine unit is overhauled, the final arc blade is broken, and if the blade is replaced, the cost is large and the construction period is long. After repeated research on finding domestic and foreign materials, he invented small membranes and entered fine welding, which solved this problem and saved more than 650,000 yuan for the enterprise. At the beginning of 2017, the factory installed and ordered the Shandong Zibo Jingao used steam turbine, inspection found that the steam pipe flange weld root has serious unsolder penetration, adjustment valve sealing surface grooves are serious, part of the thrust tile Ujin shedding and other major defects, in the construction period is tight, difficult, he after three consecutive days and three nights of fine welding, so that the problem has been completely solved, after the steam drive heat network circulating water pump into operation, the heating period can increase the daily power of the Internet by about 8kWh. In a unit overhaul, the internal cavitation of the water ring vacuum pump equipment after the repair welding cracks appeared, he through the use of new nickel-based welding consumables, local heating ring cooling and other processes, to ensure the quality of post-welding, the annual saving of standard coal 144.41 tons, reduce carbon dioxide emissions 336.37 tons.
With superb welding experience and skills in non-ferrous metals, Wenwu has been dispatched by the factory to Participate in important external welding maintenance work in power plants such as Binhai, Hegang, Qitaihe, Liangzihe, Jiutai, Jilin, Hunan Tongguan, Hunan Shimen, Huachuan and other power plants for many times, and has completed the task excellently and added glory to the enterprise.
Preach and teach, and gather the talents of craftsmen
Monofilament does not form a line, and a single tree does not become a forest. The martial arts in the body of the skill also take into account the heavy responsibility of imparting skills, he is willing to be a ladder, unreservedly will be his mastery of the operation skills and welding theory knowledge, pour out all to the young welders, as long as others are willing to learn, he will tirelessly talk, hand in hand to teach. For more than 30 years, he has trained more than 50 qualified welders, under his careful and meticulous guidance, many apprentices have been rated as technicians, senior technicians, factory labor models and advanced figures, becoming the technical backbone of the enterprise, the mainstay, and making outstanding contributions to the development of the enterprise.
Diligently seeking in skills, knowing things, meticulous and perfect in details, teaching each other in inheritance, and sparking the original, this is the best annotation made by Wenwu for the spirit of craftsmanship. In 2019, with his superb welding skills and unremitting pursuit, he made the Wenwu Skill Master Studio pass the provincial recognition and financial support of Heilongjiang Province, and since then, Wenwu has opened a new journey in life. Through the establishment of the studio, he conducted in-depth exploration and research on the application of new welding technology in the production technology of thermal power plants, and filled the relevant technical gaps in the field of welding of electric power enterprises. At the same time, with the creation of the studio as a platform, we will continue to "pass on" wisdom, "help" out of growth, and "bring" out of culture in the way of "passing on help", and cultivate and cultivate more talents with high-quality welding operation skills.
He led the members of the studio to invent the pipe welding argon filling protection device through continuous research and exploration. The use of this device not only reduces labor and engineering costs, improves the welding pass rate, saves the amount of argon gas, and has considerable economic benefits, and has now applied for a national patent. It also solves many problems such as T23 small tube welding technology public relations and reheater tube welding (12Cr1MoV/TP347H) and "power station steam valve sealing surface alloy layer repair welding". His paper "12Cr1Mo/VTP347H Xeno Steel Welding" was published in the national journal "Industry", and he participated in the compilation of Heilongjiang "Welding Training Textbook" as an associate editor.
Craftsman spirit is the craftsman's spirit concept of meticulous craftsmanship and excellence in their work, and constantly pursues perfection and perfection in welding work. People cannot do without pursuit, and only when the pursuit of life is synchronized with the needs of society can they truly reflect their own value and the meaning of life. Wenwu is based on his own post, hard work, love and dedication, with inheritance and research, relying on concentration and tempering, with his superb operation skills and a high sense of responsibility, the spirit of craftsmanship is vividly displayed.
