Feng Xiaochen seemed not to notice the strange gazes that everyone was looking at him, but continued calmly:

"In fact, the welding process of the web of the main beam is not very difficult. I have seen our Qin Chong's materials. We traditionally use carbon dioxide gas protective welding, single-sided welding and double-sided forming, and flame correction. However, the welding effect of this method for imported steel is not obvious. Qin Chong has been exploring ways to solve this problem by adjusting the welding wire grade and changing the current and welding speed, but there has been no breakthrough so far."

"You are right." Xu Wenliang said, "Is there a better way for Director Feng?"

"Of course there is." Feng Xiaochen replied without hesitation, "The effect of using low-frequency pulsed argon arc welding will be significantly better than carbon dioxide protective welding. For 8mm plates, a v-shaped bevel is used. For 16mm plates, a U-shaped bevel is used. By changing the pulse current, dimension arc current, voltage, frequency, argon flow, etc., it is possible to weld an ideal double-sided forming effect."

"Low-frequency pulse argon arc welding?" Xu Wenliang widened his eyes. Of course, he was not unaware of this technology, but he didn't expect to use it in this occasion. In his subconscious, he felt that the cost of argon arc welding was too high and was not worth using to weld such components, so he kept spinning around the circle of carbon dioxide protective welding, but could not find a path. After Feng Xiaochen made this point, he suddenly realized that this was a very good idea. As for the cost issue, he really thought too much, and the thickness of the steel was reduced by several millimeters. The cost saved was enough for him to buy a new argon arc welding machine. No matter how expensive argon gas is, can it be more expensive than steel?

"Oh, Director Feng, you really wake up the dreamer... I laughed at you, I laughed at you, I have been doing technology for more than 30 years, but my knowledge is not as good as..." Xu Wenliang was a little incoherent. At the end, he felt a little embarrassed. Gong Zhenxing was just talking about his age, saying that his working years are not as good as Xu Wenliang's working years, and now he can fight back. What's the use of your working years? Who knows if your big steamed buns you have been eaten by dogs for so many years?

"Director Feng is worthy of being from the central government. Our technical level is really convinced." Gong Zhenxing said half complimentary and half sincerely. People don't just know one or two terms and come over and point fingers. V-shaped bevels and U-shaped bevels, and they are very clear-headed. It's hard for you to accept it or not.

Feng Xiaochen did not give up, but continued, "Mr. Xu, do you think it would be better for me to solve this technical problem with one word, or should you spend two months to explore it yourself?"

"This..." Xu Wenliang was not easy to answer. He did have different answers, but he just gave him some advice. If he said that his advice was not good, wouldn't it seem too inappropriate? Maybe people would think that he was trying to save face. He was clearly taught a lesson, but he still had to say that he was right.

Feng Xiaochen said it for him: "Mr. Xu, I know what you mean. You want to say that it is a good thing to give someone guidance, but it is necessary to explore it yourself, because you can feel that it is shallow on paper. Only what you have tried can truly understand. Is that true?"

"Actually, I have a little bit of this." Xu Wenliang replied dumbly.

"You are just trying to make a fuss!" Wang Genji said disdainfully.

"I..." Xu Wenliang was embarrassed by Wang Genji. He wanted to say that he was not making any arguments, but had some truths, but could not say them.

Feng Xiaochen waved his hand to Wang Genji, signaling him not to stimulate Xu Wenliang anymore, and then said, "The idea of ​​General Manager Xu is indeed reasonable. We cannot just engage in ideology, but we must know both the truth and the reason. It is very necessary for us to pay some time and money as tuition for some technologies. In this sense, it is also a necessary process to experiment on our own."

"Director Feng is right." Xu Wenliang responded in a low voice, and glanced at Wang Genji from the corner of his eyes, for fear that this bastard would come out to slap in the face again. Feng Xiaochen was so calm that it was suffocating, and Wang Genji was so arrogant that it was annoying. The combination of these two heroes really made Qin Chong's old men unable to withstand it.

Feng Xiaochen said: "Self-reliance and the introduction of technology have never been contradictory. It is paranoid to emphasize one aspect blindly. In the past, we only knew how to rely on ourselves, but it turned out to be closed to the country. After 156 items, almost no advanced technology was introduced from abroad. When we opened the country a few years ago, we found that people had disappeared. This is a lesson.

Nowadays, the country proposes to introduce technology, and there is indeed a tendency to blindly worship foreign countries in society. It is believed that everything we have done in the past should be abandoned and buy a modernization directly from abroad. This idea is undoubtedly wrong. If we do not have our own things and rely entirely on introduction, our industrial lifeline will eventually be pinched to the hands of others, and we will never become a real industrial power.

What we should do is to introduce one hand, innovate independently, learn from the strengths of the barbarians to control the barbarians, so that we can catch up. Is this the truth?”

"Director Feng said so well!" Song Hongsheng praised the first thing he could do. He had already felt that Director Feng had a little bit of affair and was prepared. Although Xu Wenliang was a skilled expert, he could not play with Feng Xiaochen because he was unintentional. Regardless of whether Feng Xiaochen's words made sense, at least Qin Chong could not continue to fight, otherwise he would be humiliating himself.

Gong Zhenxing also nodded and said, "Director Feng's words make a lot of sense. After all, he is the leader, and his understanding of the central spirit is much better than us."

Xu Wenliang felt a little wronged. He had clearly thought about it, so why did he let this young man take it into the ditch in just a few words? When did he say he wanted to lock the country? Didn’t we also consider using imported steel to make the main beam of the crane? Also, accepting a suggestion from Feng Xiaochen that using argon arc welding instead of carbon dioxide protective welding is not inconsistent with self-reliance. Aren’t you also a Chinese?
