Chapter 3 Let me give it a try

The Red Star factory will require the delivery of the interior panels of two cars tomorrow, and then one car per day until the delivery of the 1 cars on the order is completed.

At present, in order to solve the problem, we must first solve the problem of weld blackening.Tang Fei held an interior panel and looked at it. After looking at it for a while, Tang Fei frowned slightly.

Tang Fei is not a god, and it is impossible to see where the problem is at a glance.

Noticing Tang Fei's expression, Tang Xuewen sighed, "The problem of the blackened weld seam made our hair turn white, but we couldn't find the reason, and we even invited technicians from the Red Star Factory to come over, but we couldn't solve the problem." .”

Tang Fei said nothing, but looked at the weld carefully.

This is an aluminum alloy weld, using argon shielded welding.

Tang Fei first thought whether the protection of argon gas was not in place, so that oxidation reaction occurred during the welding process, because aluminum is a relatively active metal, which can easily react with oxygen in the air.

In our daily life, we have come into contact with various aluminum alloy products, such as aluminum pots, aluminum barrels, and even aluminum lunch boxes.These aluminum alloy products do not rust and are very stable. That is because there is a dense oxide film on the surface, which is well protected, and generally will not easily oxidize and rust again.

The welding of aluminum alloy is different, there is no oxide film, the metal aluminum is fused at high temperature, and welded together, if the inert gas protection is not in place, if there is a small problem, the quality of the weld will appear.

Tang Fei first thought that this was the case, and he also rushed to this aspect to carefully inspect the welds, and even checked the welding equipment and the quality of the argon gas.

After looking around like this, Tang Fei ruled out this possibility again.

Where is the problem?

Tang Xuewen said: "Xiao Fei, forget it, I will ask Xiao He to try welding again."

Xiao He is a welder, and his level is not bad.Tang Xuewen is going to try again, maybe Xiao He can find out the problem during the welding process.

Tang Fei didn't think so. Even if Xiao He's level was good, he was only a welder after all, and his theoretical level must be limited. If he could find the problem, he would have found it long ago. It would be useless to try again, it would only waste materials.

"Dad, do you have a magnifying glass? It's better to have a larger magnifying glass."

Tang Xuewen didn't understand what a magnifying glass was for, but he still said, "I happen to have a magnifying glass, so I'll go get it right away."

Taking the magnifying glass over, Tang Fei took it and held it in his hand. With the help of the magnifying glass, he looked at the weld carefully, and even said: "Flashlight!"

A small flashlight was also brought over. With the magnifying glass and the flashlight, Tang Fei finally saw some clues, which further confirmed the inference in his heart.

It would be better if there was a microscope, but there is no such thing.Under the current conditions, that's the only way to go. It's not bad to be able to initially confirm my inference.

Tang Fei said in a somewhat affirmative tone: "Dad, I may have a solution to the problem of the blackened weld seam."

Hearing this, Tang Xuewen was agitated for a while, grabbed Tang Fei's arm with all his strength and said, "Xiao Fei, really?"

It can be seen that Tang Xuewen seemed to have grasped a life-saving straw, as if he had seen the dawn of hope. He had a look of pain just now, but now he looked excited.

Tang Fei said slowly: "Dad, I'm [-] to [-]% sure, let me try it and I'll know."

"Okay, that's great." Tang Xuewen was happy for a while, "Xiao Fei, just tell me what you need, as long as you solve the problem of the blackened weld seam, all problems will be solved."

Tang Fei asked for a thermometer, a hygrometer, and a separate room. This room was originally used to store sundries, but it has been cleaned up.

Everything is according to Tang Fei's requirements, and the air conditioner is also installed, and it is a high-power heating and cooling air conditioner with dehumidification function. All these are in place one by one according to Tang Fei's requirements.

This movement was a bit loud, and many workers were muttering, what kind of tricks were they doing? Could this solve the problem of blackened weld seams.

The small factory is not big in the first place, with only a dozen or so people.Everyone knows that there is a problem with the weld, and it is also known that the problem is serious.

Seeing Tang Fei like this, many people gathered around. The originally small room was almost full of people, and they all looked at Tang Fei in bewilderment.

This room has been transformed by Tang Fei into a temporary welding room. Thermometers and hygrometers are hung on the walls, and the air conditioner is turned on to cool down and dehumidify the room.

"Xiao Fei, is it okay? I'll ask Xiao He to come over and weld."

Xiao He, He Yadong, is about 30 years old and is the best welder.In the past few days, Xiao He has welded many interior panels, but there has always been a problem of blackening of the welds, and none of them is qualified.

Tang Fei looked at the temperature and humidity, nodded and said: "We can weld, but first, I will do it myself, and Xiao He will watch me weld a few pieces first."

You come in person?

Tang Xuewen looked at Tang Fei slightly in astonishment, with disbelief on his face, Tang Fei smiled and explained: "Dad, I learned welding in college, it's fine."

Seeing that Tang Fei was going to do it himself, everyone was even more surprised.

"Little boss, can you do it, let Xiao He come!"

A voice sounded, this is Liu Jiang, a man in his 40s, with good skills in turning, milling, planing and grinding, and a nice person.

In normal times, Liu Jiang is not only the main force of work, but also acts as Tang Xuewen's assistant, especially when Tang Xuewen is not in the factory, Liu Jiang usually manages the workers.

This is Liu Jiang's kind reminder. Tang Fei fully understood, so he smiled and said, "Uncle Liu, I learned welding when I was in school. I can do this work by myself."

During college, Tang Fei got good grades, and did a metalworking internship in a school-run factory. He did welding by himself, and his level was really good.

In the "later generations", Tang Fei was both a scholar and a practical man. He often did it himself, and his level was not bad. It was with this foundation that Tang Fei prepared to come and weld himself.

Seeing a lot of people around, and the door of the room was still open, Tang Fei put on welding gloves and a welding mask, and said loudly, "Close the door, everyone, and move back a bit."

Everyone consciously stepped back a little to make room for Tang Fei to perform.Tang Fei looked at the temperature and humidity and felt that the requirements were fully met, so Tang Fei started welding.

At the beginning, the movements were a little rusty, but gradually became proficient, and the first inner panel was welded quickly.

The welder Xiao He watched Tang Fei's welding and thought, this proficiency and technical level are better than mine. Is this really a fresh graduate?

After the welding was completed, the next step was to inspect the weld seam. Tang Xuewen immediately came over and looked at the weld seam carefully.

Xiao He, who is a welder, also came over immediately, not to mention the others, they all surrounded him, their eyes fixed on this freshly baked weld.

No!
Am I wrong!

In the entire room, there was no sound!
