"It's impossible to go wrong!" replied Bi Jianxin.

Another worker explained: "We have to go and pick up the materials before each job. The Japanese are responsible for distributing the materials, and they have to send us the materials according to the model number on the process sheet, and we have to check them together. After finishing the work every day, we have to hand in the remaining materials, and we can't keep them in our own hands, because we are afraid that we will make mistakes the next day. In those days, several of us were welding these steel structures, using No. 74 welding rods, and there was no chance of error. ”

Liang Chen also said: "Also, if we use the wrong electrode, the Japanese can find out the solder composition of these welds by testing them." They haven't said this is the reason until now, and it's clear that there is no problem. ”

"Makes sense. Du Xiaodi nodded. Solder errors are one of the important reasons for the quality problems of welds, and Tian Xiongzhe also came to find the cause of the accident, and it is impossible not to investigate this project. If it's really because of the solder's fault, they'll be held accountable. Since they didn't say that, apparently there would be no problem in that regard.

"Master Liang, give me the welding rod, I'll try it. ”

Du Xiaodi stretched out a hand to Liang Chen, and at the same time, the other hand had already grabbed the welding tongs they had brought over.

They were arranged by Naohiro Iwasaki to repair the damaged structure, and naturally they had to carry out gas cutting, electric welding and other operations. They brought electric welding machines, gas cutting machines and other equipment, and received welding rods and other materials from the warehouse, and the welding rods they received were the No. 74 welding rods that Bi Jianxin had used before.

Liang Chen handed Du Xiaodi an electrode, Du Xiaodi identified the number stamped out of the root of the electrode, and confirmed that the No. 74 electrode was correct, so he clamped the electrode on the welding tong, lifted the welding mask, and started the welding operation on a steel structure.

The welding sparks are splashed up, and they are very good-looking. Wang Ruidong and Liang Chen both turned their faces away, afraid that they would be blinded by the welding light. Bi Jianxin and other welders raised their welding masks one after another, admiring Du Xiaodi's operation through the dark glass on the mask, and at the same time expressed their admiration:

"The technique is too skilled, better than my master!"

"You also deserve to be called a master, you see the weld welded by Xiaodu, so smooth, which is like your welding, like a dog has gnawed!"

"I've definitely been doing fake welding for more than 30 years!"

Du Xiaodi didn't care about everyone's discussions. As early as ten years ago, she was already immune to this admiration, these years, although she changed her career to do scientific research, but the technology in her hand has not given up, many welding practices in scientific research, she is hands-on, so that the laboratory hired experimenters feel ashamed. Her eyes were fixed on the welded part, observing the color of the molten pool, and her hand felt the slight throbbing of the sparks.

"That's not right!"

She muttered to herself, temporarily extinguished the arc, put down the mask, and turned her head to look at the process drawings placed next to her, her eyebrows furrowed into a pimple.

"What's wrong?" Bi Jianxin stepped forward, looked at the weld, looked at the drawing, and asked puzzledly.

"The color, the color is not quite right. Du Xiaodi said.

"No, it won't. Bi Jianxin responded, "What color are you talking about?"

"The molten pool, as well as the color of the welding liquid before it cooled, this orange red is too positive, according to common sense, the molten pool should have some green when this chromium-molybdenum structural steel is welded. Du Xiaodi said.

"This ...... I really didn't notice. Bi Jianxin was dumbfounded. In his experience, of course, he knows that different steels and different solders will produce different color weld pools, but the color difference is not obvious, and he does not think there is any difference. Du Xiaodi can actually tell what orange and green are in the molten pool, what kind of demon is this, alas, it seems that he really can't catch up with this girl.

"Actually, I just feel it. Du Xiaodi hurriedly covered up, not wanting to hit the old man too hard. She is now an expert in welding research, and she naturally knows more about things such as spectrum and flame color. In normal times, she would not have observed such subtleties, but because she had heard that the Japanese had never found out the cause of the cracking, she put some thought into it and observed the details more thoroughly. Earlier, she noticed a slight deviation in the color of the melt pool and the weld before it cooled, which meant that one of the two things must have gone wrong.

"Liang Chen, I want to take a piece of welding rod and a small piece of steel out for an experiment, is there any difficulty?" Du Xiaodi asked Liang Chen in a low voice.

"You can't bring anything too big, if it's a small piece mixed in with daily necessities, it's fine. Liang Chen said.

"Okay, I'll cut a small piece of steel down and you'll find a way to help me get it out of the jobsite. Du Xiaodi said.

Of course, there are some entry and exit rules for the construction site, whether it is the person who comes in or the person who goes out, the main purpose is to worry about someone bringing dangerous goods into the construction site, or taking the gadgets on the construction site out. Du Xiaodi cut off a small section of welding rod and cut a small piece of steel, and Liang Chen directly embedded these things under the soles of his leather shoes and swaggered out of the construction site.

Du Xiaodi followed out of the construction site and took these things from Liang Chen's hands, but he didn't know where to find a place to do experiments.

Three days later, Du Xiaodi returned to the construction site with a stack of newspapers and a test report. She found Liang Chen and Wang Ruidong, and after discussing with them, they went to Iwasaki Naohiro's office together.

"Mr. Iwasaki, in the name of Quanfu Company, I ask you to explain this matter!"

Wang Ruidong slapped a few newspapers in front of Naohiro Iwasaki, his face was cloudy as if it was going to rain, and he said seriously.

The interpreter at the construction site translated Wang Ruidong's words to Iwasaki Naohiro, who was a little annoyed by Wang Ruidong's rudeness at first, and when he looked down and saw the newspapers, his face turned a little pale.

Naohiro Iwasaki was no stranger to those newspapers, in fact, he had seen them more than a week ago, and had discussed with Yu Uchida about the contents of the newspapers. He originally thought that these reports of pouring dirty water on the Chinese would not be seen by the Chinese, and as long as they did not hold the Chinese workers accountable, the matter would be considered a thing of the past. Who would have thought that the Chinese actually saw these newspapers, and some people circled the relevant reports with a red pen and wrote Chinese notes on the side, which made Naohiro Iwasaki unable to deny. Although he didn't know Chinese, he knew some Chinese characters as a Japanese, and he knew that Chinese did understand the contents of these newspapers.

"It's just a misunderstanding, I think, a misunderstanding on the part of the journalists. Naohiro Iwasaki said.

"Is this really a misunderstanding? The newspaper said that Mr. Uchida Yu specifically emphasized that there is only one difference between this project and other projects undertaken by your company, and that is the use of Chinese workers, do you think this is not pointed?" Du Xiaodi directly began to ask in Japanese.

When she was training in Japan, she had already learned some Japanese, and until now she was in graduate school, she has been reading Japanese literature, and she has mastered Japanese vocabulary and grammar very well, but her spoken language is still slightly insufficient, but it is enough to cope with this kind of conversation. She kept a low profile a few days ago, because she didn't want the other party to notice her intentions. Now that she has got the handle of the Japanese side, of course she can publicize it. You know, she doesn't represent herself, behind her, there is Feng Xiaochen's black hand supporting her.

"I think Mr. Uchida just stated a fact, but he didn't say that the Chinese workers were responsible for the accident. Naohiro Iwasaki said.

"Mr. Iwasaki, don't you think it's shameful to play such a trick?"

"Miss Du, I reiterate once again that we don't mean to blame the Chinese workers, it's just a misunderstanding on the part of the journalists. ”

"Since it is a misunderstanding, can you please clarify it again, explaining that the operation of the Chinese workers is flawless, and there are other reasons for the occurrence of this accident. ”

"This ...... I'm afraid it's not necessary, right? Moreover, the matter is still inconclusive, and we are not in a position to make such a clarification. ”

"What does Mr. Iwasaki mean is that the Chinese workers are responsible for the accident?"

"At least so far, it cannot be said that Chinese workers are not responsible. Naohiro Iwasaki said stiffly.

"If that's the case, then we'll have to hold our own press conference. Du Xiaodi sneered.

"What are you going to say at the meeting?" said Naohiro Iwasaki, "and if you make irresponsible remarks, you will be prosecuted by law." ”

Du Xiaodi shook the test report in his hand and said: "Since we are going to hold a press conference, we will naturally have definite evidence to prove our innocence." Mr. Iwasaki just said that this matter is still inconclusive, and I happen to have a report here that may give some explanation for this accident. This is a copy of the report, and I can leave it to Mr. Iwasaki to study before asking you to determine whether or not to hold a press conference to clear our name. If we do not receive a reply from Mr. Iwasaki within three days, we will have to submit the report to the representatives of Hauge and ask them to administer justice. ”

With that, she gently threw the report in front of Naohiro Iwasaki, then stood up, bowed slightly to Naohiro Iwasaki, turned around and walked out of the office. Liang Chen and Wang Ruidong both smiled, leaving Naohiro Iwasaki with a threatening look, and then followed Du Xiaodi away.

"This ...... What's going on?"

Naohiro Iwasaki was a little confused by the strength of the Chinese, he took the report thrown to him by Du Xiaodi, flipped through the two pages, and couldn't help but change his face.

"Quick, go and invite Mr. Ta Xiong to come to me, and Mr. Uchida!"

Naohiro Iwasaki commanded loudly to his subordinates, completely lacking the calm appearance he usually had.
