Pursue the ultimate practice“Craftsman's unique skill”
2002，Meng Wei graduated from Xugong Technical School with excellent results.，Enter XCMG Heavy，Soon after, he became the first batch of CNC lathe workers in the factory with his excellent lathe skills.。
Having never been exposed to the knowledge of numerical control, he relied on his tenacity.，From the most basic《NC programming and machining》Start learning，In order to realize the machining of complex parts,，He's still deadPro/E、CADAnd other kinds of drawing software.，Study hard and practice hardCAMAnd other computer-aided programming software，From the computer“Xiaobai”Become an expert.。
In addition to hard study，Meng Wei also actively participated in skills competitions at all levels.，Promoting Learning by Competition and Widening the Vision of Skills。He won the national technical expert in one fell swoop.、Provincial champion and many other honors，He has been employed as the National Communist Youth League for three consecutive years.“Revitalization Cup”Skills competition expert。
Strive for perfection“Accuracy of heavy device”
November 2021，XCMG Heavy Duty 5 100-ton ClassCSeries of new products released。As a landmark product of localization of high-end all-terrain crane，In lifting performance、Dynamic performance、Intelligent level、The maneuverability level has reached the world's leading level.，And all parts are made in China.。
This is the first time in the industry to realize the complete localization of large-tonnage cranes.，Behind it，Meng Wei's efforts are also indispensable.。
Meng Wei led the team through the dual-slot knife partition control technology.、Radial integrated automatic clamping technology，Have successively conquered the single-cylinder bolt cylinder head、Central body of revolution、Difficulties of 6 core components such as cable drum for length measurement。After millions of wear and load tests，The test performance of 6 kinds of parts fully meets the design requirements.，Its performance has reached the international advanced level.，Break foreign monopolies，Completely get rid of foreign technical constraints.。
September 2, 2022，New Jin“The world's first crane”——XCA2600 andXCCThe 2600 came out，Made in China Stunning the World Again。The key components of the 2600-ton crane，They are all from Meng Wei and his team.。
In the process of research and development，The bearing capacity of the original super-lift transfer structure has reached the limit of the 2000-ton crane.，The newly designed heavy duty switching structure is too complex.，Industry can not overcome the problem of processing accuracy，As a result, the global crane tonnage can not be broken through.。
For this reason，Meng Wei did the left before and after.、18 kinds of non-standard cutting tools such as right one-way forming cutter，Pieced together a new switching structure bit by bit.。Tested，The transfer structure processed by Mengwei fully meets the demand of 2600 tons.，Meng Wei once again contributed to Made-in-China with the ingenuity of pursuing excellence.。
Dare to be the first“Make a top soldier with wisdom”
In recent years，Rapid development of digital technology，Meng Wei takes the initiative to embrace the opportunities of the intelligent era。2018，He led the design and manufacture of the first intelligent production line of parts in the industry.。
Nowadays，Parts intelligent manufacturing production line has been successfully in 8-Application of 2600t series wheel crane in the process of automatic processing of fixed body，Forming the first multi-product and multi-model mixed production in the industry、Intelligent seamless production scheduling、Discrete Intelligent Machining Line for Deep-hole Parts with Over 100 Steps，And reach the international leading level.。
After the application of intelligent production line，Meng Wei further shortened the seven processes to three.，The processing cycle is shortened by 2 days.，The efficiency is improved by 300％。
Do not change the original aspiration to build“Innovation team”

December 2017，Meng Wei was selected as the fifth batch of industry professors in Jiangsu Province，He was employed as a practical tutor in three higher vocational colleges such as Jiangsu Institute of Safety Technology.，Horizontal scientific research projects have been carried out with Jiangsu Institute of Safety Technology.《Optimization and training of robot flexible welding process for core components of new generation crane》And other projects，It adds new types of work and specialties to the school.，It has also trained reserve technical talents for the company's welding machine.。
Meng Wei has compiled more than 30 textbooks on the advanced operation methods he has mastered.，Among《Machining Technology and Tool Application of Digital Turning》《Advanced Operation Application of CNC Lathe》Five books have become the designated teaching materials for the training of multi-skilled workers in enterprises.。Under his guidance and cultivation.，Fourteen people won the first prize in the national skills competition.、22 people were evaluated“National technical expert”、Six people won“Jiangsu province skill champion”、Nine people were promoted to senior technicians.、25 promoted to technician。
Meng Wei participated in the compilation《National Vocational Skill Standard for Grinder》，Compilation《Construction of Provincial Question Bank for Lathe Workers》，The healthy development of standardization in the whole industry.。Meng Wei also volunteered.，There will be stunts in the company.、Trick、The first-line backbone elites with unique skills come together.，Establishment of Meng Wei Skills Master Studio，To build the studio into a craftsman talent“Incubator”。July 2017，Meng Wei Skills Master Studio was rated as the national level“Skill Master Studio”。
