Take root in the "North Pole" without fear of hardship.
Bai Weidong was born in Bayan County, Heilongjiang Province. At the age of five, his father who followed the army to change jobs responded to the call of the state and came to Mohe outpost forest farm, which is known as the "cold forbidden zone". Because of his parents’ poor health, he chose to work after graduating from junior high school in order to reduce the economic burden on his family. In 1992, he went to Heimotui No.351 to work on ship machinery, and became the youngest chief engineer in Sanjiang in just three years. After that, I engaged in the maintenance of forestry machinery and equipment, disassembled and assembled all kinds of forestry machinery and equipment, and had an extraordinary obsession and love for mechanical principles.
In 1996, Mohe IKEA Wood purchased the most advanced automatic production line equipment of laminated timber from Taiwan Province at that time, and was in urgent need of an equipment maintenance technician. He applied to IKEA Wood as a repairman. To maintain the equipment well, he needs to have rich knowledge of electromechanical and electrical integration, but he only has junior high school education. Therefore, he ate and lived in the workshop, studied mechanical principles while studying accessories against drawings and equipment, and spent two months studying the equipment thoroughly with a thorough and persistent tenacity, and the equipment integrity rate remained above 99%, which was praised by the county bureau and company leaders.
Enthusiastic research and development achievements "great country craftsmen"
With the development of deep processing of wood, the demand for large-scale load-bearing wood beams and columns is increasing, and the requirements are getting higher and higher. However, the existing universal wood processing equipment in the industry can’t meet this demand. He used the valuable theoretical knowledge and practical experience accumulated in practice to design and manufacture YJ12500L special-shaped load-bearing wood beam splicing machine, which was successfully put into production and obtained a patent for utility model. The first wooden beam produced on this machine tool was exhibited at the National Forest Expo, and was personally nominated as "the first wooden beam in China" by Jia Zhibang, former director of the State Forestry Administration.
He presided over the completion of the project "Manufacturing Technology and Application of Special-shaped Load-bearing Wood Beam Splicing", and developed 25 sets of wood component processing equipment, which can save more than 30% of wood. Over the past few years, it has created accumulated benefits for enterprises of 63 million yuan. In particular, the finger joint technology and hollow technology can be widely used in large-scale wooden buildings and long-span bridges, filling the international gap. The project won the second prize of National Science and Technology Progress Award (Workers Group) and Heilongjiang Science and Technology Progress Award. Lijian, an academician of China Academy of Engineering, commented on this: The research results of this project are innovative, comprehensive, strategic and applicable. Promoting the development of wood structure industry will greatly boost the development of low-carbon economy in China and build beautiful China.
Bai Weidong’s mind was not carried away by the successful achievements of technological transformation, and Do not forget your initiative mind made great efforts to move forward. He led the design team to skillfully overcome the technical difficulties by using the thinking of "flexible contraction", and manufactured a hydraulic round-splicing machine for hollow wooden columns, which can produce hollow wooden columns with any diameter and length within 300 mm-1,200 mm, filling the gap of similar equipment at home and abroad, and won the invention patent and the second prize of the second China Forestry Industry Innovation Award.
Keep learning and become an industry expert.
He taught himself professional knowledge such as "Steam and Hydraulic", "Mechatronics" and "Forestry Lifting Conveyor", consulted more than 500 documents and made more than 200,000 words of reading notes. At the same time, humbly consult and learn from well-known domestic experts in Harbin Institute of Technology, China Academy of Forestry and other scientific research institutes, and study hard to solve technical problems in the field of wood structure production and construction.
In 2011, he led the team to undertake the national "Twelfth Five-Year Plan" science and technology project — The project "Design Research and Demonstration of Larch Structural Nodes" participated in the national "Twelfth Five-Year Plan" project — Research and development project of energy-saving wood skeleton wall materials. The paper "Design of Bending Test Device for Larch Plywood Beams" was published in Mechanical Engineer. As the main drafter of the national standard "Code for Design of Wood Structures" GB50005-2017, it provided important data and technical information for the formulation of national standards. In 2014 and 2017, through the transformation of existing patented technology and application results, it applied for Daxinganling Shenzhou Arctic Wood Co., Ltd. to become a "high-tech enterprise". "Shenzhou Arctic" wooden house has passed the CE certification of the European Union.

Reject temptation and dedicate to forest cause.
With the achievement of various scientific and technological achievements, some enterprises have been optimistic about his ability and technology, and they have taken the initiative to come to the door and hired him at a heavy price. Every time, he politely declined. He often said: "It is the green forest in Daxing’ anling that has nurtured me, and it is the pure land in Mohe, the Arctic that has cultivated me. Enterprises are in a period of transformation and development. How can I forget the benefits!" Re-tempting conditions, and then generous treatment; It can’t change his love for his hometown and his dedication to the enterprise.
On the way to chasing dreams, there are both the joy of success and the profound pain. Eight years ago, when welding the frame of L-shaped wood beam splicing machine, he accidentally caused a serious sprain and dislocation of the elbow joint of his right arm. In order to catch up with the work progress, he missed the best treatment time because he didn’t see a doctor in time, leaving a permanent wound on his arm, which has not been able to straighten up so far, and he often feels dull pain at night. He has been working in hard conditions for a long time and has not eaten in time, which has caused him to suffer from stomach diseases and arthritis. However, he knows that the road to innovation is full of thorns and bumps, and it is inevitable to pay and sacrifice! If scientists, technicians and craftsmen are compared to the three inseparable links in China’s creation, then Bai Weidong is the link of "Longjiang craftsman". He said, "I would like to contribute all my wisdom and strength to the revitalization of Longjiang! Polish the brands of "Made in China" and "Created in China" with the spirit of "great country craftsman" and make our ordinary workers take the responsibility of the times for realizing the Chinese dream! "
