God-level industrial master

Chapter 4 Problem Solving
This, this, this is the standard "fish scale welding", very beautiful, this kind of weld can only be welded by high-level skilled welders.

"Wow!"

Someone exclaimed, everyone is considered to be a person in the machinery industry, and it's not like they don't understand anything. Everyone knows that this weld is extraordinary.

This appearance is simply...

Liu Jiang was the first to accept it, happily, and said loudly: "Little boss, this is one of the most beautiful welds I have ever seen. It is a typical fish scale welding. Maybe the welders in the Red Star Factory are not as good as you. .”

Hearing such words, Tang Fei was naturally happy in his heart. He never expected that just because of Xiaolu's hand, everyone would have such a big reaction.

After looking carefully, Tang Xuewen immediately became excited, and said loudly: "Xiao Fei, it's amazing. Not only is the weld very beautiful, but there doesn't seem to be any sign of blackening. What's going on?"

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

Visual inspection is called visual inspection. Visual inspection is not enough. Penetrant and developer must be used to further inspect the weld.Next, Tang Fei didn't need to do anything, Xiao He hurriedly inspected it, and used the special penetrant and developer for inspecting welds, and the welds were completely qualified!
Tang Fei also smiled happily. It was successful. The weld seam was completely qualified and beautiful.Tang Fei, who was in a happy mood, immediately explained what was going on.

"Dad, the welding seam looked black before, which is caused by the welding environment. The temperature and humidity are not up to standard. The welding seam is full of dense and tiny holes. These holes are very small and invisible to the naked eye, but the light shines on them When there are these small holes, the light is absorbed and not reflected, so the weld looks black."

After listening to Tang Fei's explanation, Tang Xuewen nodded and thought in his heart, so that's the case.Xiao He, the welder next to him, has quite a lot of experience in himself, but this is the first time he has heard that this is the reason for the blackening of the weld seam.

Tang Fei said: "The humidity in the workshop is a little bit beyond the standard, so the welding is temporarily carried out here, and the interior panels are put outside for storage after the welding is completed.

Qingjiang City belongs to the south. In summer, it is hot and humid. The air humidity is very high these days. There are some places on the ground that are full of water droplets, and the welding of aluminum alloys has very strict environmental requirements. Strict, when the humidity is high, the water vapor in the air will form dense tiny holes in the weld, so it is strange that the weld does not turn black.

The reason became clear, and Tang Fei also formulated strict welding standards. The temperature was controlled at 25 to 40.00 degrees, and the humidity was within [-]%. According to this environmental standard, the next welding was carried out by Xiao He, and Tang Fei supervised and guided.

Everything went well, and Tang Xuewen was in full bloom.

The welder Xiao He also said in admiration: "As expected of a college student, it's amazing!"

Hongxing Electric Locomotive Factory is not only a star enterprise in Jiangnan Province, but also a star enterprise in the national locomotive manufacturing system. It can be seen from the huge factory area that this is not ordinary.

Red Star Avenue used to be a two-lane road, but it was expanded to six lanes by the rich and powerful Red Star Factory a few years ago, with an asphalt road. The bullishness of Red Star Factory can be seen from this straight and spacious avenue.

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

Tang Fei has already learned that the price of these interior panels is not cheap. For example, the interior panels processed by his factory are not too big. Each car costs tens of thousands of yuan. No wonder his father borrowed money from usury Engage in the processing of interior panels for locomotives.

Drive in from the south gate of the Red Star Factory, walk along the factory road to the logistics area of ​​the assembly workshop, Tang Fei was secretly startled at the logistics area, there are so many trucks here.

There are at least a dozen large and small trucks, and there is a long queue. It can be seen that many machinery processing factories in the surrounding area are doing the business of the Red Star Factory, and there are many delivery vehicles every day. They have no choice but to wait in line.

After waiting for about half an hour, it was Tang Fei's turn. After unloading, inspection, and signing, everything was done. Tang Fei felt happy and felt very rewarded.

There was no problem with the inspection of the inner panels of the two cars, and they passed smoothly. The inspectors and logistics personnel in the final assembly workshop of the Red Star Factory signed the delivery notes. checkout.

Red Star Factory, Purchasing Center.

Chen Guihong, the director of the Purchasing Department, was looking at a purchasing report. At this moment, a team leader from the Purchasing Department came over and said anxiously: "Director Chen, the number of drawings that Jiuzhou Motorcycle Parts Factory processed for us The interior panels are about to be vacant, what should I do?"

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

For a large factory like Hongxing Factory, even for spare parts with the same drawing number, there are usually two or three or four suppliers.For the interior panels of those drawings, Jiuzhou Motorcycle Parts Factory has processed 30 vehicles, and Jinjiu Motorcycle Parts Processing Factory has also processed dozens of vehicles.

Yang Jun said: "Director Chen, if this Jiuzhou Motorcycle Parts Factory can't supply goods all the time, shall we disqualify him?"

Chen Guihong said angrily: "Place the 5000 yuan appraisal form first, and if the supply cannot be supplied the day after tomorrow, terminate the order with Jiuzhou Motorcycle Parts Factory."

It can be seen that Chen Guihong became murderous, and Yang Jun next to him nodded, ready to follow Chen Guihong's request. At this time, a young man walked over with a happy face.

"Director Chen, Team Leader Yang, Jiuzhou Motorcycle Parts Factory has sent over the interior panels of those drawing numbers, and the final assembly workshop has signed the order, and will not report any vacancies."

Yang Jun said: "Xiao Liu, really?"

Xiao Liu said affirmatively, "It's absolutely true."

Yang Junzheng felt relieved, while Chen Guihong lost his temper, and said angrily: "Playing the piano indiscriminately, and blatantly shoddy it, it's too abominable!"

Yang Jun was startled, and immediately asked in confusion: "Director Chen, what's the matter, since the other party delivered the goods as scheduled, it's a good thing."

"A good thing?" Chen Guihong snorted coldly and said, "Come on, I'll take you to have a look and see if it's a good thing or not."

Yesterday, Chen Guihong went to Jiuzhou Motorcycle Parts Factory in person and saw the problem of blackened welds with his own eyes. Chen Guihong did not believe that Tang Xuewen could solve this difficult problem of blackened welds so quickly.

After returning yesterday, Chen Guihong also went to consult the welding experts in the factory. The experts frowned after hearing this, and 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. He must have sent those inner panels with blackened welds over to deal with it, and tried to get away with it.

Chen Guihong, who was furious, told Yang Jun and the purchaser Xiao Liu about the situation while walking, and the two were also angry for a while.

After understanding what happened, Yang Jun said even louder: "Director Chen, this is too bad in nature, we must strictly examine 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 about to board the car and go back with the signed delivery note.

Seeing Chen Guihong approaching angrily, Tang Fei had seen Chen Guihong yesterday, so he stopped and waited for the three of Chen Guihong to approach.

Chen Guihong saw the interior panels that Tang Fei sent over at a glance, picked up one of them without saying a word, tore off the protective film wrapped around the interior panels, and prepared to get angry.

"what!"

"How could this be? The weld seam didn't turn black."

Not only did the weld seam not turn black, but it was also very flat and beautiful. The typical "fish scale welding" was of first-class quality. Chen Guihong was stunned and looked at Tang Fei in disbelief.

Yang Jun and Xiao Liuhe approached, and they looked at the weld seam seriously, with a puzzled look on their faces, Xiao Liu even said: "Director Chen, the weld seam of this inner panel is not black!"

Yang Jun picked up another piece and looked at it. The weld seam was still smooth and beautiful without any sign of blackening. Yang Jun was also stunned.

Seeing the appearance of the three of them, Tang Fei vaguely guessed something, so he smiled and stepped forward a few steps: "You are Director Chen, I am Tang Xuewen's son, and today I am sending the interior panel here on behalf of my father. This is from us. The interior panels of the two cars, Director Chen, how is the quality?"

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