Great power Craftsman: 80 after welding master Wang Feng for Chinese missile perfect seam "blood vessels"
source: observer network
will be 4 mm diameter (cell phone charge line size), wall thickness of only 0.5 millimeters, different curved shape, easily deformable The stainless steel pipes are welded together. The weld needs to meet the standard of the first level of the space of the space (higher than the national standard) and control the deformation so that the steel ball with a diameter of 2 millimeters is passed smoothly. What is this level?
this is the masterpiece of Wang Feng, master of welding after 80. A seamless "suture" for a variety of complex zero components of the missile has been made, and the finished product must be resistant to high pressure, corrosion resistance and air tightness. It is difficult for surgeons to suture blood vessels and skin. With the spirit of hard work and excellent technology, the success rate of a welding problem with a previous success rate of only 30% was 100% in his hands. In May 19th, Qianlong Network reported the story of "the first welding torch" of the 283 factory of the second Aerospace Science and technology factory.
"surgery" master Wang Feng
Wang Feng, 36 years old this year, Beijing Pinggu people, with a yearning for space space, a graduation to the second Institute of space science and technology to work in the second Institute, has been 15 years. As the welding master and senior technician of the 283 factory, Wang Feng is skilled in argon arc welding technology, and is more complex than the complicated parts.
15 has been involved in all types of welding tasks in the second house. In the development of a complex and difficult welding attack, Wang Feng became the first welding torch for manual welding in the workshop.
nibbling down this "hard bone"
a day before the Qianlong Network reporter came to the workshop of 283 factory, when he saw the "first torch" Wang Feng, he was welding a part. The blue arc is glinting, and a smooth uniform silver seam welds the two parts together.
putting down the work at hand, Wang Feng told reporters that aerospace products are characterized by zero defects due to their particularity. Many complex parts can not be completed by automatic welding machine, and can only rely on manual welding. The stringent quality standards put forward higher requirements for the welding technology of their operators.
Wang Feng told reporters, before, the welding of a shell was a big problem that plagued their 283 factory sheet welding shop, which was called the most difficult work to do in the years. "According to the requirements of the product, the weld must reach the first grade weld of the space standard and carry out the one hundred percent - ray inspection. At the same time, it needs to pass the strength test. Only two items are qualified and the welding is qualified."
Wang Feng said, because the product is a special material, a little careless in the welding process will appear blowholes and slag, forming welding defects, the former welding qualified rate can only reach 30%. When he took over the task, he felt heavy burden on him. "It is either a success or a product abandonment. We must be cautious and not make any mistakes."
in order to chew down this hard bone, in nearly 1 years, Wang Feng repeatedly carried out welding tests. In order to master the change of welding pool in real time, the eyes must be fixed to the solder joint when welding, and a seam down 3 minutes without blinking.
in order to meet the requirements, Wang Feng trained continuous welding for three minutes without blinking hard Kung Fu
"welding attention, eye to, hand to hand, hand eye coordination is very important." Wang Feng finally found the knack by pondering, trying and improving over and over.
the heavenly body! In the past, the appearance difference of the weld can be identified by naked eyes. After Wang Feng's continuous improvement, the weld is more and more beautiful, and the quality is good. There were no quality problems in the hundreds of shells welded by Wang Feng's hand, with a pass rate of 100%.
becomes welding "the first man"
one of the noteworthy details is that Wang Feng's work is particularly fine. Before each welding, he always scrubbing the platform carefully and scraping the spare parts clean and clean. The gloves for his welding are always snow white and never see his work clothes. A little bit of oil. He said that we must take every detail seriously and decide the success or failure in detail.
with this strict and serious attitude, these years, he has conquered a number of difficult tasks, some of the welding tasks in the factory only he can complete, become the workshop recognized welding "the first person".
as a "first person", there must be something else.
in a workshop interview, many of Wang Feng's colleagues told reporters that Wang Feng's popularity was that he could weld multiple stainless steel pipes with a diameter of 4 millimeters (the size of a cell phone), a wall thickness of only 0.5 millimeters, different curved shape, and easily deformable. Higher than the national standard), and control deformation, so that the diameter of 2 mm steel ball passed smoothly.
excellent technology is only one of them. What's more, Wang Feng always pays attention to the combination of "diligently" and "perseverance". According to Wang Feng, in order to ensure quality and efficiency, in order to ensure quality and efficiency in a project, he worked from 8 a.m. until second a.m. at 2 a.m. for 18 hours. In addition to eating lunch boxes in a hurry, he continued to work. After the
task was completed, he went to have a snack with the workshop workmates. Wang Feng, who never drank, drank three bottles of beer in one breath. Everyone was surprised. Wang Feng was embarrassed to say, "I am very dizzy. I forgot to drink water all day, and the tea was too hot. I was thirsty."
Wang Feng is not only very famous in the factory, but many enterprises and research institutes are also looking for the door, so that is to ask Wang Feng to help weld some complex products.
in a major project, the Institute for general design has been in contact with a number of units, and eventually the product processing task is handed over to Wang Feng's unit, of which Wang Feng's excellent welding skills have played an important role in it. Finally, in the workshop and Wang Feng's research, the product was delivered on schedule, and the task was completed.
the international competition shows "real work"
it is particularly worth mentioning that Wang Feng is not only famous at home. He also showed the Chinese real Kung Fu in the international welding competition.
2013 August, the Tenth International Welding competition in Ukraine was held in Odessa, a black sea pearl. The competition invited 64 top players from China, Ukraine, Belarus, Russia, Bulgaria, Czech and 6 countries. Wang Feng was lucky to be one of the players.
on the final day of the situation, Wang Feng is still fresh in memory. In a square, a game less than 6 square meters is closely linked to each other, forming a square playing field, separating the stadium from inside and outside the stadium. Wang Feng's match time is 12:30-13:30 noon, and the temperature has climbed to more than 30 degrees.
"at that time, I was wearing a sky blue welding suit, while I was quick to do the welding preparation, while fast thinking of the possible conditions of welding, assembly, fixation, grinding, welding, one ring link..." Wang Feng recalled to reporters that at that time, hot weather and intense competition made him totally wet through.
he said that the first time he stepped out of the country to participate in the international competition, in addition to the lack of experience, he had to overcome the difficulties with the host and the referee's language. At the same time, foreign welding technical standards, competition rules and domestic differences made him more difficult to deal with the competition. "
" is different from that in China. There are specific rules for every welding time in foreign countries. Some welding requirements are different from domestic welding habits and are difficult to adapt to. Wang Feng told reporters that, in addition, the tungsten argon arc welding project in this competition in the competition because of the number of competitors, high technical content has become a big hot, at the same time, the project has been the traditional strength of foreign players, Chinese players want to stand out to get the place of great difficulty.
great power craftsman "spicy chicken silk!"
finally, Wang Feng, who won the runner up with solid fundamentals and stability, showed the excellent welding level of Chinese skilled workers. When Wang Feng got on the podium, the overseas players shouted, "spicy chicken shredded chicken, spicy chicken shreds!" Russian translated as: "good, good!" The applause expressed the praises of the overseas Chinese to the Chinese athlete.
although Wang Feng has gained many honors and achievements over the years, he has never stopped struggling. In Wang Feng's view, a good environment is very important for the realization of dreams. Space has given him the stage to dream and let his dream illuminate reality.
talk about the future, Wang Feng said that it will climb the peak, grasp all the time to study the domestic and foreign frontier technology, step by step accumulation and innovation, to contribute to the missile manufacturing, and constantly improve the level of welding skills.
