"I want to use my innovative technology in a wide range of welding work to make the job better. On December 19, 2023, the worker who is introducing innovative invention technology at Huaneng Dezhou Power Plant is Cheng Ping, from an ordinary welder to winning the "Shandong Provincial Model Worker", he uses welding flowers to interpret the craftsman spirit of the new era. In his ordinary position, he interprets the professional value and life pursuit with perseverance, perseverance and innovation.
The welding difficulty is welded by mirror reflection, and the weight is controlled below 125 kg all year round
At present, Cheng Ping serves as the leader of the welder squad of the maintenance department of Huaneng Dezhou Power Plant. "With solid basic skills and rich experience, we also need to further break through ourselves, such as encountering some welding difficulties can not use the inherent 'stupid' method, at this time we must combine the actual innovative operation. ”
In the summer of 2013, Texas was at the peak of electricity consumption, when the medium temperature reheater leaked, and the damaged pipe should be welded and the damaged pipe should be destroyed in a large area, and the pipe should be cut off layer by layer from the outside, and the leakage point should be repaired and then restored from the inside to the outside. Because it is summer, Cheng Ping considers that the time of electricity consumption is not allowed, and there must be a large number of welds in the welded pipe, and the more welds, the more leakage points will appear. In the end, Cheng Ping climbed to a gap of about 40 centimeters, crawled into it, and used the mirror to reflect the leaking pipe for welding, which took 3 hours.
Cheng Ping made welding his career, and in order to keep his body flexible and able to drill into some narrow pipes, he never ate staple food for dinner and had to do several sets of push-ups and sit-ups every day. "I have 1.74 meters, but since I was 18 years old, my weight has been around 125 pounds. ”
An innovation studio was established to innovate new welding processes for many times
In 2017, Cheng Ping Innovation Studio was established, and "Innovation, Make You and Me Brilliant" became the golden sign of Cheng Ping Innovation Studio. He led the team to innovate new welding processes and technologies, and successfully completed various urgent, difficult, dangerous and heavy welding work, and successfully dealt with more than 30 welding technical problems.
During the Spring Festival in 2020, in order to ensure the resumption of work and production on schedule after the holiday, the key project of Hualu Hengsheng 12.6 billion yuan green chemical project in Shandong Province, in the face of the severe epidemic prevention and control situation, Cheng Ping led 3 commandos to fight for 5 days and nights, used up 240 kg of welding rod, and completed the set goal ahead of schedule.
In addition, Cheng Ping independently innovated the welding process and successfully solved the welding problem of PB160 titanium alloy stator of the key project of national deep-sea exploration and the pressure bearing problem of the welding parts of the rear swing hose of the engine of the aerospace Suzaku 2 launch vehicle, making outstanding contributions to the development of China's deep-sea exploration and aerospace industry.
It is worth mentioning that after more than a dozen tests of tensile, bending, impact, cladding, etc., Cheng Ping's team independently innovated the new technology of "Stellite cemented carbide vacuum water-cooled surfacing repair process", which increases the service life of the joint surface of high-pressure valves by 3 times compared with the traditional process, and saves about 500,000 yuan in costs per year. In addition, the team used cold welding and other processes to weld the fracture along the large shaft of the pump, repair the holes of the large cast iron screws of the secondary filter volute, improve the process of plugging the high internal leakage of the 300 MW unit, and repair the fan caliper to increase the efficiency of the enterprise by 12 million yuan.
A number of innovative processes have been applied for patents, and the automatic wire feeder fills the gap in the international welding industry
In 2020, Cheng Ping led the team to submit 10 international and national patents such as invention patents such as welding rod convenient strip extractor and manual argon arc welding automatic wire feeder, among which the manual argon arc welding automatic wire feeder filled the gap in the international welding industry.
In addition, Cheng Ping and his team have applied for a patent for the folding welding slag fire umbrella invented. "At that time, the original intention of inventing the fireproof umbrella was to prevent fires caused by falling welding sparks during high-altitude work, and the invention of the fireproof umbrella could play a good role in fire prevention. Cheng Ping explained.
In the past, welding was covered with fireproof cloth, so laborious and laborious, after the invention of the folding welding slag fireproof umbrella, it can be folded up and taken away at any time, and the folding umbrella can be opened during high-altitude welding operations. Cheng Ping introduced that in 2021, the folding welding slag fireproof umbrella and arc light collection and reuse mask were selected as the first major craftsman display and promotion products, and are currently purchased and used by many enterprises.
Cheng Ping said that innovation is endless. "I will lead my team to overcome difficulties, take on the responsibility and mission of 'welding craftsmen', and cultivate more skilled talents for the construction of a strong industrial province. ”
