The elf-like Mars jumped around with dazzling lightning. Although Chen Guilin had been standing around, no one said anything more. He could only watch him operate the electric welding and weld the two steel plates together.

Although the two pieces of scraps are not small in size, the welding length is still too short compared to the real pressure vessel, so the difficulty is naturally reduced a lot. Chen Guilin completed the welding operation without taking it for too long.

"It's over?"

Steven put down his goggles and looked at the watch on his wrist, feeling a little disbelief: "Your welding method doesn't seem to have improved anyway. Why can your welding speed be so fast? This is unreasonable. The welds you weld like this must have defects!"

"You can detect whether there are any defects." Chen Guilin made a move away and made a gesture of asking.

Steven looked to the side and nodded to Dave and Kaite. Two DuPont welding engineers walked over and began to test Chen Guilin's work results.

Non-destructive testing, destructive testing, ultrasonic, x-ray, magnetic, and fluorescence penetration. Fortunately, the workshop in Shengzhong is complete and there are no shortage of destructive testing tools. Stretching, impacting, bending, and a steel plate seems to be put into the alchemy furnace of Laojun. After a series of "tortures", it took longer than Chen Guilin's welding, and Dave and Kate stood back to Steven in a little puzzled way.

"It meets the requirements completely, even better than our previous technology." Kate was speaking. Dave looked at the broken steel plate at this time, not knowing what he was thinking.

"How did you do it?" Steven was a little confused. Looking at Chen Guilin's operation before, except for the faster speed, it seemed that it was no different from their technology!

Why does the same thing happen? When it comes to Chinese people, it feels like magic, and the speed is completely incomprehensible and nearly one-third faster?

You should know that this is not just a problem of fast speed and saving working hours. Faster operation means higher work efficiency, and also means lower technical requirements for welders. In the past, the company may have to pay 5,000 US dollars a month, but if the technical requirements are reduced, the company only needs to hire an ordinary welder with a salary of 3,500 US dollars a month to be competent, which means that the cost reduction will be great.

Chen Guilin pointed to an attachment under the steel plate on the station, an inconspicuous and ordinary ceramic welding pad.

"Is this a high-tech pad developed by you? What technology was used? What special materials were used? Or what treatment was carried out?"

"No, it's just an ordinary ceramic welding pad." Chen Guilin touched the still-heat pad with his hand and said, "Your technical requirement is to pull the welding pad as much as possible, which is also a requirement of ordinary welding. But your steel is not good, the pads and steel plates must be compacted, and there must be no gap. The direction of your efforts is wrong."

“Compress?!”

Steven, Dave, and Kate looked at each other: "Is it that simple!"

Is it simple...

Chen Guilin's lips moved, but in the end he did not say what was in his stomach. Perhaps, this little change seemed really simple, but how could the sweat behind this be to discover its rules?

In order to prevent the welding work from being hindered by the project, Chen Guilin spent almost all of his food, drink and accommodation in the workshop during that period. He only had electric welding in his eyes. In order to catch up with the progress, he tried various methods but failed.

The normal idea in welding is to pull the substrate apart for welding. How many attempts will it take to break the inertial thinking that has been used for a lifetime and can you think of compacting the substrate!

A very simple change is behind Chen Guilin's sweating and wet shirts countless times.

But Chen Guilin disdains to talk to Americans about these hardships. If they think it is simple, then just think about it!

"Mr. Steven, if the technical improvement is on the substrate, it will obviously not have any impact on the welding quality, right? Your inspection just now should have explained the problem."

He Renming and Mo Gaowen looked at each other, but they couldn't suppress the ecstasy in each other's eyes.

"I think we don't need to consider our certification qualifications for the time being. Let's talk about whether DuPont is interested in purchasing our improved technology?"

"this!"

...

There was a burst of intense piano sound from Chen Guilin's home, which was the sound of "Destiny".

Chen Xiaoyuan's hands danced like a butterfly on the piano keys, and exciting music burst out.

Zhang Xiaoju looked at Chen Guilin standing against the door with a complicated expression, wanting to say something, but in the end she only sighed. Perhaps, like Chen Guilin, she was a person who was not used to revealing the words in her heart to the other party.

"Guilin, I'm leaving, take good care of Xiaoyuan." Zhang Xiaoju turned around, hesitated for a moment, and walked slowly towards the stairs of the Tongzi Building.

"Xiao Ju!"

Chen Guilin suddenly stood up and said, "I don't know if it's wrong to pursue a better life, but I would rather let Xiaoyuan use his hands to change his life than to count on someone else."

"You always say that I am not enterprising when I hold an iron rice bowl, but a real iron rice bowl is not about eating in one place for a lifetime, but about having food everywhere you go."

"I'll give you this sentence too."
