The conversation between the two inspectors did not hide it from Zhao Guoyang's ears.

After his rebirth, his eyesight, ears, and physical fitness have improved significantly compared to his previous life. This may be a kind of reward for God's survival.

After hearing the two of them complain for a while, Zhao Guoyang couldn't help laughing: "Two masters, do you think I can't fix these leaked fuel tanks, right?"

"Ah! This..." After hearing this, the inspector Lao Ma looked a little embarrassed.

Lao Wang, who was on the side, was quite tough and replied directly: "Secretary Xiao Zhao, it's not that we are relying on our seniority. We have been doing this fuel tank inspection for several years."

"In my impression, leaks of the same level as just now are unsuccessful. Even if you find the leaking part, it is easy to have a series of problems such as uneven welding during the welding process, which will greatly affect the strength of the fuel tank."

When Lao Wang spoke, he felt a sense of confidence in his tone. It can be seen that although he had never done technology, after so many years of inspection work, his understanding of some professional knowledge is not inferior to that of some technicians.

After Lao Wang finished speaking, Zhao Guoyang nodded and said, "What Master Wang said makes sense. Generally, gasoline tanks that are equipped with gasoline are not suitable for repairing like this."

"Because this can easily cause internal stress damage to the fuel tank body, thereby affecting the strength of the fuel tank. However, what Mingke Tractor Factory wants is the tractor oil tank, which is a diesel-burning, so I am a little sure of this."

When Lao Wang heard this, his eyes changed a little when he looked at Zhao Guoyang. He was a veteran and had a deep understanding of the performance and repair of different fuel tanks.

This statement from Zhao Guoyang obviously proves that he also understands the fuel tank industry and is not a junior brother.

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 subject to the same problem when re-welding. But why did Zhao Guoyang dare to be so confident?

Thinking of this, Lao Wang shook his head: "I don't agree with Section Chief Xiao Zhao's words. If only one or two leaks, it may be possible to rework."

"But the unqualified rate of this batch of fuel tanks is too high. In my opinion, it is impossible to repair all of them. If you don't waste the delivery time, the only option is to re-preparate the materials and re-made them all."

Zhao Guoyang didn't argue with him, but just smiled and said, "Since that's the case, then Master Wang, let's take a bet."

"If I can't repair this batch of fuel tanks within two days, then I will lose. At that time, I will buy you two packs of Hongtashan to apologize, but if I really repair this batch of fuel tanks and fully meet the inspection requirements..."

"Then I, Lao Wang, will compensate you for two packs of cigarettes! That's it! Lao Ma, testify!" The inspector Lao Wang said with a fist.

In his opinion, he almost won the gambling game.

Even if Section Chief Xiao Zhao really has a unique level of rewelding and can keep the weld at a very high level, the time he takes to repair each fuel tank is definitely a long time, and maybe one will take one or two hours.

If the pass rate of 120 fuel tanks is calculated at 30%, it means that this young technical department chief needs to repair a total of 84 fuel tanks within 48 hours, which is simply impossible.

After hearing the two of them set the bet, Lao Ma secretly gave Lao Wang a thumbs up.

Obviously, in his opinion, he was basically sure to win this bet.

Hua Guosheng and Xu Dongfeng soon returned with two large drawings.

Taking the drawing into his hand, Zhao Guoyang carefully looked at it from top to bottom. He did not check the dimensions of length, width and height, but looked carefully at the thickness of the fuel tank, the flip size and the rounded corner radius of the corners.

After careful examination, Zhao Guoyang quickly found the problem.

It turned out that the thickness of this batch of fuel tanks in the past was about 1.2 mm, the flip length was about 15 mm, and the rounded corner radius was 10 mm.

It should be said that the current data is appropriate. The fuel tank made based on this data should be of little problem.

But it should be noted that the size of the new fuel tank is now a circle larger than the previous fuel tank, and the rounded corner radius has also changed accordingly, at least 2 to 3 mm larger.

However, since Hua Guosheng did not issue new drawings to the production department, the flip length of this batch of fuel tanks was still 15 mm below.

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

In addition, the fuel tank body has a wall thickness of 1.2 mm, which is easy to cause problems if there is a slight deviation in welding.

After finding the problem, Zhao Guoyang sighed secretly.

He nodded to Hua Guosheng, pointed to the line "Flip length 15mm" written on the technical requirements and said: "Master Hua, when you explained to the people in the production department, you should not have specifically raised the question of flip length, right?"

Hua Guosheng was stunned for a moment and suddenly understood. He was an old skill. After Zhao Guoyang prompted him, he naturally knew where his negligence was.

After the fuel tank is larger, the flip length must be adjusted and must not be placed at the original 15 mm.

Why did I forget this at the beginning? When I was anxious, Hua Guosheng's legs became a little weak.

Xu Dongfeng, who was standing beside him, still yet, touched his head and said to himself: "Why should I specifically mention the length of the flip? Isn't 15 mm enough?"

"You kid don't study hard, do you understand a bird? Say a few less words!" Hua Guosheng said angrily.

Seeing Hua Guosheng's angry look, Zhao Guoyang patted his shoulder and comforted him: "Master Hua, don't worry. Now we have found the problem, just make up for it."

Zhao Guoyang's comfort obviously did not have any effect, and Hua Guosheng next to him was still frowning.

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

"Maybe you don't know much about it. Re-welding of fuel tanks is difficult and time-consuming. Especially for this batch problem, if we re-weld one by one, it may be more time-consuming than re-producing a batch of fuel tanks..."

Hua Guosheng lowered his head and pondered for a moment, then raised his head and continued, "Guoyang, so I will go and ask Director Wang for instructions and ask him to ask him to purchase another batch of materials."

"There are two days left. In any case, we will drive out this batch of fuel tanks! There is really no way, so we can only let the workers in the workshop work overtime."

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