China News Service, Lanzhou, January 28 (Reporter Wei Jianjun and Li Yalong) "Let every steel plate be seamless." As a welder super operator and senior technician of Lanzhou Lanshi Group, 30 years of welding flowers in the workshop , So that Wei Benqiang has the titles of "Golden City Craftsman" and "Gold Medal Worker of Gansu Province". He said that in the field of welding, there is no limit to learning, and innovation is still needed to move forward.

  The predecessor of the Lanshi Group, the Lanshi General Factory, was founded in 1953. It was once China's largest production base for oil drilling machinery and refining and chemical equipment.

China's first pressure vessel was born in Lanshi, the cradle of China's petrochemical equipment industry, and a place to train and bring up "big country craftsmen".

  In December 2020, the Gansu Provincial Model Workers and Advanced Workers Recognition Conference was held in Lanzhou. Wei Benqiang, director of the first workshop of professional manufacturing and welding of Lanshi Heavy Equipment Refining and Chemical Company, was awarded the title of "Gansu Province Model Workers".

"This is the honor of the past, but also the starting point of innovation." He said.

  "Master Ma Qiang once represented Lanshi in Beijing to participate in the National Pressure Vessel Welder Skills Competition, and won the first place!" Wei Benqiang recalled that in 1990, the 22-year-old was assigned to Lanshilian after graduating from the welding major of technical school. He became an electric welder in the chemical factory, and Ma Qiang was his guide. "The older generation of masters not only taught me technology, but also passed on the fine tradition and spirit of model workers."

  With the welding flowers flying in the workshop, Wei Benqiang has been working here for 30 years.

According to statistics, there are thousands of pressure vessels welded by him.

He has grown from an ordinary technician to a national-level electric welding operation skill "master", and led the studio members to devote themselves to technical research and innovation in the field of super large pressure vessel welding, to overcome production problems and promote enterprise technology upgrades. .

  Wei Benqiang also actively explored the training model of high-skilled talents, established a unique "step-wise progressive training system", imparted modern welding processing technology to his students without reservation, and trained more than 1,000 employees. He has completed nearly The welding work of one hundred domestic leading major new equipment has obtained the utility model patent certificate for the "gas shielded welding gun bracket device".

  Wei Benqiang said that although the welding work is hard, dirty and tiring, there will be a certain sense of accomplishment when actually welding a beautiful work.

It's just that the safety measures decades ago have not been perfected, and it is often necessary to pay the price of welding spatter flying into the clothes and being burned.

"A welding rod head that was hot red at the time. When it was replaced, the welding rod head fell on the shoe and burned a five-centimeter long stamp."

  "If the welding is not good, what are the consequences?" Wei Benqiang always puts safe production and quality assurance in mind.

He said that the past products were simple, and the current products are complex, irregular shapes, and welding difficulties have increased. The welding materials have also been expanded from a single material in the past to a variety of materials and some special materials. This requires skilled workers. The skill level has to be continuously improved.

  On some occasions when welding, Wei Benqiang will also shoot some wonderful videos, post them on the Internet, and share them with colleagues and apprentices.

"Now the skills of individual apprentices have surpassed me, and I am honored." He said that the company will often hold some welding competitions to learn welding skills, on the one hand to improve skills, on the other hand to find work day after day Have fun.

  In recent years, Wei Benqiang has taken the lead in participating in many research projects and has contributed to the advancement of China’s welding process technology. Lanshi first solved the problem of dissimilar steel welding in China, and at the same time filled the domestic nickel-based welding wire automatic welding technology. blank.

He proposed the "rigid fixation method surfacing" and "preserved deformation method surfacing" operation methods, which overcome the problem of tube sheet surfacing deformation.

  He presided over the preparation of technical documents such as "Selection of Groove Processing Forms", "Welding Methods and Techniques", and "Interpretation of Welding Work Standardization", which played an important role in production after application.

  In Wei Benqiang’s model worker innovation studio, the reporter met with one of his apprentices, Xie Wanfa, who is already the deputy director of the company’s second professional manufacturing and welding workshop. He met his master Wei Benqiang when he entered the factory in 2008. “The school learned pure theory and practice The job is different, and the master teaches it by hand.” One year later, under the leadership of the master, I started welding very skillfully.

  Xie Wanfa said that at first he didn't know anything about welding, and the quality of welding was particularly poor. The insiders felt like "chicken shit" at first glance, which was particularly ugly.

From vertical welding to horizontal welding, the master teaches them hand in hand, allowing them to grow up quickly. He has grown from a junior worker to a backbone of the business. "Now the works can be used as works of art, just like the master said. Yes, make every steel plate seamless."
