Hurry up and call them over, especially Shen Jiayue, she is afraid of the cold. During the lunch break, sipping the hot health tea that had just been boiled and chatting about the newly learned gastronomic skills, several girls in the soldering team of the Punching Rubber and Plastic Branch of China Hangfa West Control Technology immersed themselves in a short relaxation.
As members of the soldering class who undertake the irreplaceable manual work of the enterprise, the five female generals with an average age of more than 30 years have become a model for a new generation of Western controllers with the mentality of "doing it to become a boutique" and "living a delicate life". They make parts at the heart of the aircraft engine, which require extreme precision and are subject to high temperatures and pressures.

5 team members in exchange discussion
Solo
On the morning of April 15, in the soldering class, team leader Hui Shanshan held tweezers in her left hand at a level of 180 degrees, and held a soldering iron in her right hand at a 90-degree vertical, carefully staring at the filter less than 5 mm in diameter in front of her. The tweezers extended her fingers, and the strainer turned lightly with the weld under her tweezers.
Such a "shape" makes Hui Shanshan more comfortable and the processing efficiency is higher. In just one minute, more than 20 filters have been hung up. She conveniently put 10 oil filter components on the scale, and when she saw the result showing 0.219 grams, Hui Shanshan smiled very easily: "Hang the tin evenly, OK!" ”
This is not a routine way to check the quality of filters, but it is her long-term confidence and experience as a soldering team leader.
The parts made by the soldering team are very small micro parts, no more than ten centimeters long and only three or five millimeters short, which must be placed in the palm and fingertips for processing, and the production process is extremely difficult. If you are not careful, the parts will be scrapped, and the heavy parts will hurt themselves, which can be called a solo dance on the fingertips.
Due to the particularity of manual work and the high standard of part accuracy requirements, team members often have to take off protective gloves for processing. "Long-term exposure to liquids such as acetone and alcohol makes the skin on their hands become rough and dull, and some even their fingerprints become blurred." Wang Yongbo, deputy secretary of the party branch of the branch and chairman of the trade union, said.
Li Qing is the old man's hand of the team, her hands have been "full of holes", and the molting and cracking of the fingertips are the norm.
Perfect
The welding task of oil filter components has tens of thousands of pieces a month, and each team member has to complete thousands of pieces. But the filter in each person's hand will eventually enter the "heart" of the aircraft engine and will not tolerate any flaws.
The new filter processing is coming, and the time is tight and the task is heavy. In a hurry, Hui Shanshan and Hu Linmei divided their work and cooperated, one welding the first and third processes and filters, and the other welding the second process and cap cap, with cross-drying. One person has to do four days of work, two people work together, one day to get it done, and the mutual inspection is interspersed into the operation process, which not only relieves the personal tension, the efficiency is greatly improved, and the quality is more guaranteed.
"Quality is '1', there is no '1' in the front, and no more '0' in the back is in vain!" Team member Hu Linmei said.
Although the soldering class is "pure hand", "high precision" is still a "hard standard". One day last summer, a special processing task for tiny filters came. "The process is complicated, the size is huge, and it is a hard bone to gnaw!" Hui Shanshan said.
That day, Hui Shanshan borrowed a bunch of molds with her apprentices and explored them one by one. Although I processed several prototypes before leaving work, I always felt unsure. To verify the retired master, "It is very important to draw silk, about 12 to ensure its size." Master Liu Wen's words made Hui Shan Shan Dai enlightened, and she quickly processed a set of components according to the master's instructions, until it was accurately assembled, and she had a bottom in her heart.
"One afternoon, a group of people were trying all kinds of filters the size of fingernails, how could they not be tired?" Team member Shi Liqun joked that every time they faced a tense task, they also wanted to be lazy. But for everyone, the best "laziness" is to achieve 100% quality at once.
Inheritance
Pure handmade, irreplaceable, which is not easy for 5 girls. Aside from lunch and going to the bathroom, their basic state is welding.
When processing a certain product, the filter and sleeve are not satisfied, which can upset Hui Shanshan. "Although my master has retired, I still made a video call to her." Hui Shanshan said. The master said, "Put on a bakelite board and make a circle." According to the master's instructions, the filter and sleeve are like children who can understand the words, and they are immediately obeyed.
The team is passed on by such a "primitive" word of mouth.
As the fifth generation of the team' inheritors, Shen Jiayue, a member of the post-00 team, under the cultivation of master Li Qing, not only achieved hands-on operation in just one year, but also achieved the current efficiency of five or six pieces per minute.
"On the first day of entering the factory, Master Hui Shanshan told me that the 'power dream' relies on generations of inheritance, and we must not only know how to inherit, but also always remember and carry it forward." Shen Jiayue said.
Without craft photos, it is difficult to accurately pass on the essence. As the fourth generation team leader, Hui Shanshan has not only undertaken the task of cultivating new people over the years, but also led everyone to summarize the previous difficulties and skills, and through repeated study of various component process specifications and tooling fixtures, each step of the processing process was intuitively displayed in the form of pictures, and the standard operation instructions for each oil filter component were written, from traditional language teaching to writing books.
A number of tasks have just been successfully completed, and new tasks have arrived. Rough and dull, even fingerprintless hands affect the beauty of their bodies, but they can't hide the delicacy that is being created on their fingertips.
