The local heat treatment is also carried out very smoothly, because not only there is a detailed process, but also, yesterday afternoon, the use of scrapped combustion casing was tested, and the operators are more skilled.

When the residual temperature of the local heat treatment gradually dissipated and the repair welding position returned to room temperature, Li Tianfeng said confidently: "Mr. Yang, the whole repair process is completed, let's measure some key dimensions of this combustion chamber casing." ”

"Yes, measure now." Yang Xianfeng waved his hand and immediately decided.

Yang Xianfeng spoke, and the sheet metal workshop did not dare to slack off, and immediately arranged two experienced inspectors to come over with measuring tools. When the two saw so many leaders here, they immediately meticulously measured the size, and each size measured would be recorded one by one.

After the measurement was completed, one of them gave the size of the measured value record table to Li Tianfeng.

Li Tianfeng took this record sheet, swept it slightly, and then handed it to Yang Xianfeng and said: "Mr. Yang, the repair welding is very successful, all sizes are qualified, and there is no deformation of the combustion casing." ”

After taking the size measured value record sheet and looking at it, Yang Xianfeng was in a happy mood and said happily: "Comrades, the repair work is very successful, and the next few combustion chamber casings will be implemented according to the technical plan of Expert Li. ”

Very successful, no deformation!

Everyone looked at Li Tianfeng in surprise, and some of them even admired their eyes, everyone was a technical expert or a technical backbone, usually arrogant, and basically did not serve anyone, but this time, many people were completely convinced.

Such a difficult technical problem was perfectly solved by Li Tianfeng.

Li Tianfeng's heart is also good, after solving such a problem, he still has a sense of accomplishment in his heart. The repair welding of the first burner casing has been completed, but the next step of verification is to verify that the combustion chamber casing is still leaking oil after the repair welding.

So, Li Tianfeng smiled and said loudly: "Mr. Yang, experts, the repair welding work has been completed perfectly, and we will pump it again to verify it in the next step to see how the repair effect is." ”

"Yes, pump it out." Everyone agreed, and everyone wanted to see for themselves, after such a perfect repair, the combustion chamber casing still leaked oil in the end.

In everyone's mind, of course, it is believed that more than ninety percent of the combustion chamber casing will not leak oil, but it would be better to be able to see it with your own eyes.

As a result, the combustion chamber casing that had just been repaired was quickly hoisted into the large pool, and after being filled with air at three atmospheres, everyone watched intently at the situation of the combustion chamber casing that had been submerged in the water.

One minute, two minutes, three minutes......

Ten minutes passed, and the clear water was very calm, not a single bubble came out, not even a small bubble.

Seeing such a situation, many people glanced at each other, and then nodded lightly to each other, as we all know, the fault of the oil leakage of the combustion chamber casing is completely repaired.

Li Tianfeng also knew that the combustion chamber casing repaired by his own set of plans would definitely not leak oil again, and now, after verification, this is indeed the case.

At this time, Li Tianfeng thought in his heart, the leakage of lubricating oil in the combustion chamber casing was over, at least it had nothing to do with him.

Li Tianfeng has already decided that he will soon submit his resignation while he has solved this big technical problem and Yang Xianfeng is in a good mood.

After his resignation, the verification and commissioning work of the combustion chamber casing, the technical quality improvement work, etc., basically have nothing to do with themselves, and in the future, their energy will be all invested in Tianfeng Technology Co., Ltd.

……

On the same day, that is, the afternoon after the oil leakage fault of the combustion chamber casing was successfully solved by Li Tianfeng, Li Tianfeng resigned.

Li Tianfeng's resignation soon spread throughout the entire E factory, especially the precision machining center, everyone was shocked, they were speculating, what was wrong, Li Tianfeng is now in full swing, how could he resign at this time, the news will not be fake.

Li Tianfeng did resign!

In the afternoon of the same day, Li Tianfeng carried his resignation letter and went to Yang Xianfeng's office in person. When Li Tianfeng said that he was ready to resign, Yang Xianfeng was stunned for a long time, thinking that he had heard it wrong.

After confirming that Li Tianfeng was really ready to resign, Yang Xianfeng tried his best to keep it, and even made a lot of promises, what to raise within a year, how many levels of salary, what to include in the key training ranks, etc., these conditions are very attractive to ordinary people, but Li Tianfeng will not take these to heart.

Thanks to Yang Xianfeng, Li Tianfeng still resolutely wanted to resign, probably knowing that it was impossible to keep Li Tianfeng, Yang Xianfeng also put down the shelf of the chief engineer and had a good talk with Li Tianfeng, and the two talked in the office for more than an hour like old friends.

No one knows what was specifically discussed, only the two people involved.

Coming out of Yang Xianfeng's office, Li Tianfeng went to visit Liu Qingshan, deputy chief engineer. Li Tianfeng has a good impression of Liu Qingshan, plus Liu Qingshan usually treats himself well, and now he is leaving Factory E to visit Liu Qingshan, which is the least politeness.

In Liu Qingshan's office, Li Tianfeng agreed to stay for more than half an hour, and chatted with Liu Qingshan for a long time.

Such as Peng Xuehai, Cheng Gang, Chen Dong, Meng Qiang, etc., even if he was about to leave Factory E, Li Tianfeng was still polite, came to the door one by one, sat down, chatted, and expressed his gratitude to everyone.

Half of an afternoon passed. The people who should visit went to visit one by one, said goodbye, and finally, Li Tianfeng returned to his office in the precision machining center, packed up his things, and prepared to leave Factory E.

Li Tianfeng didn't have many things, so he could fit them all in a small cardboard box, pack up his things one by one, and put them into the small cardboard box one by one.

Li Tianfeng was packing up his things in the office, and the news had spread.

"I heard that Expert Li is resigning, is it true?"

"It's true, I just saw Expert Li packing up in the office?"

"It's a pity, how good Expert Li is, he actually left us at this time, leaving Factory E."

"Yes, but I think it's a pity that it's not necessarily, according to Expert Li's skills, maybe he can make some achievements outside."

“……”

Precision machining center, whether it is office personnel, or front-line employees, everyone is hotly discussing Li Tianfeng's resignation, from everyone's tone, it can be seen that there is reluctance to Li Tianfeng, and there is also a pity.

It took one or twenty minutes, Li Tianfeng packed up his things, sorted out the carton, and after seeing if there were no things left, Li Tianfeng slowly sealed the carton with tape paper, and looked at the office.

I was really reluctant to leave, Li Tianfeng thought in his heart, looked at the office again, and then walked out of the office with the cardboard box and walked downstairs.

Going down the stairs, Li Tianfeng was stunned for a moment, but he didn't think about it, at the door of the precision machining center, there were already a lot of people standing neatly, Peng Xuehai of the precision machining center, Cheng Gang took the lead, and everyone watched Li Tianfeng come over.

Seeing everyone, Li Tianfeng suddenly felt a deep emotion, his eyes were a little moist, and he tried his best to control himself and not let his tears flow.

"Expert Li, let's send you one together." Peng Xuehaidao.

"Thank you, thank you." Li Tianfeng choked up a little, and tears almost flowed down.

Peng Xuehai, the number one, personally took over Li Tianfeng's cardboard box, and a clever technician next to him immediately took over the carton from Peng Xuehai's hand, holding the carton and following everyone.

"Let's go, let's send one to Expert Li."

So, a touching and spectacular scene appeared, Li Tianfeng walked in the front, in the middle, next to Peng Xuehai and Cheng Gang, followed by dozens, hundreds of technicians, managers, and a large number of front-line workers.

The scene was very spectacular, the long queue, everyone didn't say anything, they didn't say anything, everyone accompanied Li Tianfeng, and slowly walked towards the gate of Factory E.

Walking slowly, in addition to being deeply moved, Li Tianfeng also had a kind of reluctance, what a good person, what a good factory, farewell, farewell E factory, goodbye!

……

At this point, the first volume is finished.

In the second volume, there will be a new www.biquge.info of Biqu Pavilion, Li Tianfeng started his own business, in the process of entrepreneurship, what will happen, what kind of story is there? Everyone will not be disappointed if you watch patiently.
