King of Industry

The conversation between the two inspectors was not hidden from Zhao Guoyang's ears.

After rebirth, his eyesight, hearing, and physical fitness have improved considerably compared to his previous life. Perhaps this is also a kind of reward from God for surviving a catastrophe.

After listening to the two complaining for a while, Zhao Guoyang couldn't help laughing: Two masters, do you think it's impossible for me to fix these leaking fuel tanks?

Ah! This... The inspector Lao Ma felt a little embarrassed when he heard this.

Old Wang on the side was more stubborn, and immediately replied directly: Xiao Section Chief Zhao, it's not that we two rely on the old to sell the old, we have been doing this fuel tank inspection for several years.

In my impression, there is no way to save a leak like the one just now. Even if you find the leak, it is easy to have a series of problems such as uneven welding during the repair welding process, which will greatly Affect the strength of the fuel tank body.

When Lao Wang spoke, there was a faint confidence in his tone. It can be seen that although he has no experience in technology, after so many years of inspection work, the degree of professional knowledge he understands is not inferior to that of some technicians.

After Lao Wang finished speaking, Zhao Guoyang nodded and said, Master Wang is right, the fuel tank that usually holds gasoline is really not suitable for repairing like this.

Because it is easy to cause internal stress damage to the fuel tank body, which will affect the strength of the fuel tank. However, Minke Tractor Factory wants a tractor fuel tank, which burns diesel oil. I am somewhat sure of this.

When Old Wang heard this, the way he looked at Zhao Guoyang changed a little. He has been inspected for a long time, and has deep insights into the performance and repair of different fuel tanks.

What Zhao Guoyang said obviously proved that he also knew the fuel tank business, and he was not a beginner.

But there is one thing that Lao Wang dare not agree with.

Even if the fuel tank is filled with diesel, it will still be restricted by the same problem when it is re-welded. But why does this Zhao Guoyang dare to swear so firmly?

Thinking of this, Pharaoh shook his head for a while: I don't agree with the words of Section Chief Zhao. If only one or two leaks, it may be possible to rework.

However, the failure rate of this batch of fuel tanks is too high. In my opinion, it is impossible to repair all of them. If we want not to delay the delivery time, the only option is to prepare materials again and redo them all.

Zhao Guoyang didn't argue with him, just smiled and said: In this case, let's take a gamble, Master Wang.

If I can't repair this batch of fuel tanks within two days, then I will be considered a loser. At that time, I will buy you two packs of Hongtashan to make amends, but if I really repair this batch of fuel tanks, and If it fully meets the inspection requirements...

Then I, Old Wang, will pay you two packs of cigarettes! That's the deal! Ma, you testify! The inspector Lao Wang shook his fist vigorously and said.

In his view, this gamble is almost a sure win.

Even if this little Section Chief Zhao really has a unique level of repair welding and can maintain the weld at a fairly high level, the time it takes him to repair each fuel tank must be very long, and it may take a long time to repair each tank. One or two hours.

Based on 120 fuel tanks and a pass rate of 30%, it means that the young technical chief needs to repair a total of 84 fuel tanks within 48 hours, which is simply impossible.

Hearing that the two had made a bet, Lao Ma secretly gave Lao Wang a thumbs up from the sidelines.

Obviously, in his opinion, the bet on himself, an old buddy, is basically a sure thing.

Hua Guosheng and Xu Dongfeng came back soon with two large sheets of blueprints.

After receiving the drawing in his hand, Zhao Guoyang checked it carefully from top to bottom. He did not look at the dimensions such as length, width and height, but carefully looked at the thickness of the fuel tank, the size of the flange and the fillet radius of the corners.

After careful inspection, Zhao Guoyang quickly found the problem.

It turns out that the thickness of this batch of fuel tanks in the past is about 1.2 mm, the length of the flange is about 15 mm, and the radius of the fillet is 10 mm.

It should be said that the current data is appropriate. The fuel tank made according to this data should not be a big problem.

But it should be noted that the size of the new fuel tank is now larger than the previous one, and the fillet radius has also changed accordingly, at least 2~3mm larger.

However, since Hua Guosheng did not send new drawings to the production department, the flanging length of this batch of fuel tanks was still based on 15mm.

When the fillet radius reaches 12~13 mm, the flanging length of 15 mm is not enough.

In addition, the fuel tank body still has a wall thickness of 1.2mm. If there is a slight deviation in welding, problems will easily occur.

After finding the problem, Zhao Guoyang secretly sighed.

He nodded to Hua Guosheng, pointed to the line of flange length 15mm written on the technical requirements and said: Master Hua, when you explained to the people in the production department, you probably didn't specifically mention the length of the flange. Question?

Hua Guosheng was stunned for a moment, then he understood immediately. He is an old man. After Zhao Guoyang reminded him, he naturally knew where his negligence was.

After the fuel tank is enlarged, the length of the flange must be adjusted, and it must not be placed according to the original 15 mm.

How could I have forgotten this in the first place? Feeling anxious, Hua Guosheng's legs felt weak.

Xu Dongfeng on the side still hasn't figured it out yet. He rubbed his head and said to himself: Why is the length of the flange raised in particular? Isn't 15mm enough?

You don't want to study hard, you kid? Don't say a few words! Hua Guosheng said angrily.

Zhao Guoyang saw Hua Guosheng's panic-stricken look, so he patted him on the shoulder and comforted him: Master Hua, don't worry. Now we have found the problem, we just need to fix it.

Zhao Guoyang's consolation obviously had no effect, and Hua Guosheng on the side was still frowning.

Guoyang, you don't need to comfort me. This time the problem is indeed my negligence, and I will apologize to Director Wang later.

Maybe you don't know much about it. It is very difficult and time-consuming to repair and weld the fuel tank. Especially this kind of batch problem, if it is repaired one by one, it may be more time-consuming than reproducing a batch of fuel tanks... ...

Hua Guosheng lowered his head and pondered for a moment, then raised his head and continued: Guoyang, now, I will go to the factory manager Wang for instructions and ask him to order another batch of materials from the purchasing side.

There are still two days. No matter what, we have to drive out this batch of fuel tanks! There is really no way but to let the workers in the workshop work overtime.

Hua Guosheng's mind was full of thoughts now, and he walked towards the outside of the inspection station while talking.

Hey, Master Hua, I haven't finished talking yet! Zhao Guoyang was just about to tell him that he had a way to solve this problem, and Hua Guosheng had already gone to find Director Wang in no time.
