This, this, this is the standard "fish scale welding", which is very beautiful, and this kind of weld can only be welded by a highly skilled welder.

"Wow!"

Some people exclaimed, everyone is a person in the machinery industry, not ignorant of anything, everyone knows that this is extraordinary as soon as you look at this weld.

This appearance is simply ......

Liu Jiang was the first to take it, happily, and said loudly: "Little boss, this is one of the most beautiful welds I have ever seen, typical fish scale welding, maybe those welders in the Red Star Factory are not at your level." ”

Hearing such words, Tang Fei was naturally overjoyed in his heart, but he didn't expect that just a small show would cause such a big reaction from everyone.

After taking a serious look, Tang Xuewen immediately became excited, and said loudly: "Xiaofei, it's amazing, the weld is not only very beautiful, but also doesn't seem to have any signs of blackening, what's going on?"

Everyone can see that this weld is not only beautiful, but also not black at all, on the contrary, it is as bright as new, with the characteristic metallic luster of aluminum alloy.

Visual inspection is called visual inspection, and visual inspection alone is not enough, and the weld must be further inspected with penetrant and contrast agent. Next, there was no need for Tang Fei to do it, Xiao He hurriedly checked it, and used the penetrant and contrast agent special for checking the weld, and the weld was completely qualified!

Tang Fei also smiled happily, it was successful, the weld was fully qualified, and it was beautiful and beautiful. Tang Fei, who was in a happy mood, immediately explained what was going on.

"Dad, the previous weld looked black, it was the cause of the welding environment, the temperature and humidity were not up to standard, the weld was full of dense tiny holes, these holes were very small, invisible to the naked eye, but when the light hit these holes, the light was absorbed and did not reflect, so the weld looked black. ”

After listening to Tang Fei's explanation, Tang Xuewen nodded, thinking in his heart, it turns out that this is the case. Xiao He, the welder next to him, asked himself that he had a lot of experience, but it was also the first time he heard that the blackening of the weld was the reason.

Tang Fei said: "The humidity in the plant is a little excessive, and the welding is temporarily carried out here, and the inner board is put outside for storage after the welding is completed."

Qingjiang City belongs to the south, in the summer, high temperature and humidity, the air humidity is very large these days, there are some places on the ground are damp, full of water droplets, and the welding of aluminum alloy is very strict and demanding on the environment, the humidity is a lot, the water vapor in the air forms dense tiny holes in the weld, and the weld is not black.

The reason is clear, Tang Fei also formulated strict welding standards, temperature control at 20 to 25 degrees, humidity within 40 percent, according to this environmental standard, the next welding by Xiao He, Tang Fei supervised and guided.

Everything went well, and Tang Xuewenle blossomed.

The welder Xiao He also admired it: "It is worthy of being a college student, amazing!"

………

Red Star Electric Locomotive Factory is not only a star enterprise in Jiangnan Province, but also a star enterprise in the national locomotive manufacturing system.

Hongxing Avenue used to be just a two-lane road, but a few years ago it was expanded to six lanes by the wealthy Hongxing Factory, and the asphalt road can be seen from this straight and spacious avenue.

This morning, Tang Fei personally played the role of a delivery man, and the driver Lao Zhang drove a small truck, and the interior panels of two cars were placed in the truck compartment.

Tang Fei has learned that the price of these interior panels is not cheap, such as the few drawings processed by his own factory, which are not too big interior panels, each car costs tens of thousands of yuan, no wonder his father borrowed usury to engage in the processing of locomotive interior panels.

Entering from the south gate of the Red Star Factory, along the factory avenue to the logistics area of the assembly workshop, Tang Fei was secretly frightened when he arrived at the logistics area, there were so many trucks here.

There are at least a dozen trucks of all sizes, lined up in a long line, and it can be seen that many mechanical processing factories around are doing the business of the Red Star Factory, and there are many vehicles delivering goods every day.

After waiting for about half an hour before it was Tang Fei's turn, unloading, inspecting, signing, everything was done, Tang Fei was happy in his heart, and he felt a sense of gain.

The inspectors and logisticians of the assembly workshop of the Red Star Factory signed the delivery note, and at the end of each month, they went to the Finance Department of the Red Star Factory to settle the account with these signed delivery notes.

………

Red Star Factory, Purchasing Center.

Chen Guihong, director of the first procurement department, was looking at a procurement report, and at this time, a team leader of the first procurement department came over and said anxiously: "Director Chen, the inner plates of the drawing numbers processed by Jiuzhou Locomotive Parts Factory for us are about to be shortaged, what should I do?"

Jiuzhou Locomotive Parts Factory is the small machinery processing factory opened by Tang Xuewen, Chen Guihong also went to Jiuzhou Locomotive Parts Factory yesterday, Chen Guihong frowned and said: "Lao Yang, notify Jinjiu Locomotive Parts Processing Factory and ask them to deliver today." ”

For a large factory like the Red Star Factory, even if it is a spare parts with the same drawing number, there are generally two or three or four suppliers. Like the interior plates of those drawing numbers, Jiuzhou Locomotive Parts Factory took the processing business of 30 cars, and Jinjiu Locomotive Parts Processing Factory also took the business of dozens of cars.

Yang Jun said: "Director Chen, if this Jiuzhou locomotive parts factory has been unable to supply goods, will we cancel his qualification?" ”

Chen Guihong said annoyedly: "First place an assessment order of 5,000 yuan, if you can't supply it the day after tomorrow, terminate the order with Jiuzhou Locomotive Parts Factory." ”

It can be seen that Chen Guihong was murderous, Yang Jun next to him nodded, ready to do what Chen Guihong asked, at this time, a young man walked over with a happy face.

"Director Chen, Team Leader Yang, Jiuzhou Locomotive Parts Factory has sent the interior plates of those drawing numbers over, and the assembly workshop has signed an order, and it will not be shortaged. ”

Yang Jun said: "Xiao Liu, really?"

Xiao Liu affirmed: "It's true." ”

Yang Junzheng's heart was light, but Chen Guihong was angry, and said angrily: "Playing the piano indiscriminately, it is blatantly shoddy, it's too hateful!"

Yang Jun was taken aback, and immediately asked puzzled: "Director Chen, what's the matter, since the other party has delivered the goods as scheduled, this is a good thing." ”

"A good thing?" Chen Guihong snorted coldly: "Let's go, I'll take you to see if this is a good thing." ”

Yesterday, Chen Guihong personally went to Jiuzhou Locomotive Parts Factory and saw the problem of blackening the weld with his own eyes, Chen Guihong did not believe that Tang Xuewen solved the thorny problem of blackening the weld so quickly.

After coming back yesterday, Chen Guihong also went to consult the welding experts in the factory, and the experts also frowned after listening, and they couldn't figure out the reason for the blackening of the weld for a while.

Therefore, Chen Guihong believes that it is impossible for Tang Xuewen to solve the problem of blackened welds so quickly, and it must be in order to cope with it, and sent those blackened inner plates over to shoddy, in an attempt to get by.

The angry Chen Guihong told Yang Jun and the purchaser Xiao Liu about the situation as he walked, and the two of them were also angry.

After understanding what was going on, Yang Jun said even louder: "Director Chen, this nature is too bad, we must strictly assess it." ”

The three of them walked into the assembly workshop and walked to the logistics area, at this moment, Tang Fei had completed the delivery, and was ready to get on the car and go back with the signed delivery note.

Seeing Chen Guihong coming over angrily, Tang Fei had seen Chen Guihong yesterday, so he stopped and waited for Chen Guihong and the three of them to come over.

Chen Guihong saw the inner plates sent by Tang Fei at a glance, and without saying a word, he picked up one of them, tore off the protective film wrapped in the inner board, and prepared to get angry.

"Huh!"

"How so? The weld is not blackened. ”

Not only is the weld not blackened, but also very smooth and beautiful, a typical "fish scale welding", first-class quality, Chen Guihong was stunned, and looked at Tang Fei in disbelief.

Yang Jun and Xiao Liu came over, and the two looked at the weld together, with a puzzled face, Xiao Liu even said: "Director Chen, the weld of this inner plate is not blackened!"

Yang Jun picked up another piece and looked at it, the weld was still smooth and beautiful, there was no sign of blackening, and Yang Jun was also stunned.

Seeing the appearance of the three of them, Tang Fei vaguely guessed something, so he smiled, took a few steps forward and said: "You are Director Chen, I am Tang Xuewen's son, today instead of my father to send the interior panels, this is the interior panels of the two cars we sent, Director Chen, how is the quality?"

"This, this ......" Chen Guihong didn't know what to say for a while, and said after a few seconds of "this, this": "How did you solve the problem of blackening the weld?"
