What!

Still no cracks were found!

Almost everyone looked at Yang Fan, and no cracks were found during the two inspections. Doesn’t it mean that there were no cracks in this crankshaft?

Luo Jianguo sighed softly, and he and Sun Baoguo exchanged their eyes quietly. The two of them thought to themselves almost at the same time. It seemed that Comrade Yang Fan’s judgment was really wrong this time, and there were no cracks in the crankshaft.

Gu Zhengxin shook his head and whispered: "Chief Yang, let me tell you, there will be no problem with our crankshaft."

He always believed that there would be no problem with the crankshaft, and it was even more impossible for the crankshaft to have cracks as Yang Fan said.

The whole scene was filled with buzzing discussions, and there was noisy.

"I just said, how could there be cracks in the crankshaft?"

"Oh, I didn't expect that Chief Secretary Yang also made a mistake in judgment."

“……”

Most of them were shaking their heads and sighing, but a small number seemed to be Yang Fan's die-hard supporters. They had different opinions, especially those familiar with Yang Fan in Dongjiang Shipyard.

"I think Chief Secretary Yang's judgment will not be wrong. When has he made any mistakes over the years?"

"Should wait a little longer, don't worry, see what Chief Executive Yang will do next."

Hearing the voices of these supporters, Yang Fan felt warm. Is it too early to make a conclusion so early?

No crankshaft cracks were found during the two inspections. Yang Fan seemed to be unscathed and still looked full of confidence and said loudly.

"Everyone is quiet, quiet down."

So the scene gradually became quiet, and everyone looked at Yang Fan, ready to listen to what they would say next.

Yang Fan's voice was very loud, "The crankshaft crack was not found when the visual appearance inspection did not indicate that it really did not have cracks. I believe my inference was that there were cracks on this crankshaft..."

Before he finished speaking, a technician from Hongqi Factory plucked up his courage and interrupted: "Chief Master Yang, I have checked it twice with a magnifying glass just now, and the crankshaft should not have cracks."

Yang Fan smiled and said loudly: "We all know that there are many ways to check non-destructive inspection of parts. In addition to visual appearance inspection, there are also ultrasonic examinations, fluorescence examinations, etc.."

The so-called "non-destructive inspection" is to check whether the parts have surface cracks, internal tissue defects, or internal cracks, etc.

Many people are thinking.

A technician at Dongjiang Shipyard slapped his thigh even more violently, looking excited, "Yes, you can use fluorescence to check!"

Yes, it's fluorescence test!

It is the best inspection solution to check microcracks on the surface of parts, especially cracks that are difficult to see with the naked eye. Dongjiang Shipyard happens to have a professional fluorescence examination room.

Yang Fan looked at the technician at Dongjiang Shipyard with appreciation and said loudly: "Yes, what I want to say is to conduct fluorescence examination on the crankshaft. I know that Dongjiang Factory has a fluorescence examination room. Mr. Sun. You will arrange the fluorescence examination of the crankshaft, how about it."

Sun Baoguo agreed immediately, "Yes, I'll make arrangements right away."

Gu Zhengxin smiled bitterly. He knew that Yang Fan had sex with the crankshaft and would not give up easily without fluorescence examination.

To be honest, he felt that there was no need to do this anymore. This crankshaft was carried out in the manufacturing process of their factory, including fluorescence examinations, ultrasonic examinations and other inspections, and cracks were not possible.

The arm can't twist the thigh.

Yang Fan insisted on doing this, but he had no right to stop him, so he could only follow everyone to the fluorescence examination room, but he was sure that this fluorescence examination would definitely be futile.

Under Sun Baoguo's arrangement, the crankshaft was transported to the fluorescence examination room again, and the relevant fluorescence examiners were quickly in place.

This is a professional fluorescence examination room. The fluorescence examination room is divided into two rooms inside and outside. The house outside is no different from an ordinary house. The one inside is different. It is a dark room with dim light. Once the light is turned off, there is only dark fluorescence.

Two fluorescence examiners and one fluorescence technician immediately became busy and were preparing for the fluorescence examination.

Yang Fan, Luo Jianguo, Sun Baoguo, Gu Zhengxin and others did not enter the professional examination room inside for the time being, but waited outside because some preparations before the fluorescence examination would take a certain amount of time.

It can be seen that Luo Jianguo was still worried and asked again: "Comrade Yang Fan, how sure are you?"

Yang Fan replied confidently: "At least 70% or 80% sure. If I speculate that it is not wrong, the crack on the surface of this crankshaft will be clear under fluorescence examination."

Upon hearing this, Luo Jianguo felt much more relieved.

He knew Yang Fan more well and trusted him more. Feeling Yang Fan's confidence, he finally felt much easier and determined that there were cracks in the crankshaft.

Gu Zhengxin said nothing. Feeling Yang Fan's confidence, he suddenly became a little suspicious and thought to himself, is there really cracks in the crankshaft...

When he thought about this, he was shocked and quickly said in his heart, "No, no, the design strength of the crankshaft is sufficient. Even if it works continuously for a long time at maximum power, it will not produce cracks."

He is a diesel engine, and he has a very good understanding of the strength of the crankshaft and is very confident in its service life.

Gu Zhengxin was thinking this way, and a voice interrupted his thoughts.

The technician responsible for this fluorescence examination walked out of the dark room inside and reported loudly: "Dear leaders, everything is ready, you can come in and take a look."

Luo Jianguo was the first to wave and said, "Let's go and take a look."

Although he had chosen to believe in Yang Fan and basically determined that there was a crack in the crankshaft, he still wanted to see the results of the fluorescence examination with his own eyes.

Others were not slow either. They all wanted to know whether Yang Fan's inference was correct and whether there were cracks on the crankshaft. More than ten people walked into the dark room for fluorescence examination.

The area inside is not small, about 40 to 50 square meters in size. More than a dozen people come in and don’t seem crowded. The ordinary lighting is on, and it’s very bright.

The situation inside was clear, and everyone could see the crankshaft placed on the central inspection workbench at a glance, and all preparations were done.

Sun Baoguo ordered: "Everyone is waiting to see the result, let's start now."

"Okay, start right away."

The technician in charge of fluorescence examination replied and turned off the ordinary lights by himself. Suddenly, the room was dark and he could not see his fingers.

"Bang!"

With a light sound, the technician turned on the fluorescent light in the dark room, and it was dark, and many people looked at the crankshaft on the workbench.

Someone couldn't help but take a few steps forward, looked closer to the crankshaft, and then shook his head and said, "There are no cracks, no cracks."

What!

Still no cracks?

If there are no cracks in the fluorescence examination, it can be completely determined that the crankshaft itself does not have surface cracks. Yang Fan's inference is completely wrong, which means that everyone has been in vain for so long.

Just when many people were about to sigh and thought Yang Fan was inferring something wrong, the technician who was responsible for fluorescence examination laughed.

He said loudly: "The cracks must not be visible now. I haven't applied fluorescent agent yet."

I see!

Many people breathed a sigh of relief quietly.

Without fluorescent agents, of course, cracks on the crankshaft surface cannot be seen under the fluorescent lamp. The principle of fluorescent inspection is that the cracks indicated by the penetration of the fluorescent agent into the workpiece. When the fluorescent lamp is under, the cracks will be clearly revealed and clearly.

Under the command of this technician, the two fluorescence inspectors began to apply fluorescent agent to the crankshaft, and then the situation gradually became different.

"Look, there is a crack here!"

"Really, this crack is at least fifty years long."

“There is one here too!”

There are three cracks in this crankshaft, one long and two short. The longest crack is more than fifty millimeters. It is clearly visible and fully displayed in front of everyone under the illumination of fluorescent lamps.

At this moment, Luo Jianguo and Sun Baoguo breathed a sigh of relief.

Others looked at Yang Fan one after another, and their eyes were different. There was no doubt anymore, only all of them admired him.

Awesome!
Chapter completed!
