King of Industry

Seeing that the dispute was about to start again, Zhao Guoyang coughed quickly and said, "Leaders, masters, please listen to me."

"When I was in college, I was an intern in a welding factory in another province, and I knew more or less about welding problems. Just now, Master Hua said that the problem of 'porosity' is common in the industry, and I agree with this."

"Because there are indeed many welding factories, in order to save trouble, they did not pay too much attention to this issue. After all, one or two 'air holes' will not have much impact on the use of most weldments."

"But as far as our product is concerned, since it is used as the frame of a motorcycle and is a very important part of the vehicle, the problem of 'air holes' cannot be taken lightly." Zhao Guoyang followed the conversation.

Looking at Zhao Guoyang, who had always been taciturn, talking freely without any stage fright, Wang Youchang was astonished as if seeing him for the first time.

Mu Aijun and Ma Jian beside them also looked at each other in blank dismay, quite surprised.

Zhao Guoyang didn't notice the eyes of the leaders, and continued: "Motorcycles, I believe everyone has a certain understanding, the core part of which is the frame besides the engine."

"Once there is an air hole problem in the frame, it is likely to reduce the effective cross-sectional area of ​​the weld, thereby reducing the compactness of the frame, and it will also have a great impact on the load-carrying capacity and fatigue strength of the frame."

Having said that, Zhao Guoyang turned his head to look at Hua Guosheng and said, "So, I can only partially agree with Master Hua's opinion just now."

"The problem of 'air hole' may be solved by other manufacturers and other products, but since we are supporting a large enterprise such as Siyang Group and supporting important components such as the frame, it is absolutely not allowed to appear. Such a problem, otherwise, there is only one result, which is what everyone sees—return the product!”

After hearing Zhao Guoyang's words, Hua Guosheng's face turned blue and red.

He has an aloof personality and has never been very convincing. Now he was scolded by a fledgling college student, so he was naturally full of displeasure.

"Hmph, you're so eloquent, if you didn't know, you'd think you were in the sales department." Hua Guosheng tilted his head and hummed.

"Xiao Zhao, now that everyone knows the problem, can you find a way to solve it?" Director Wang said casually.

"Of course!" Zhao Guoyang said confidently.

"What? Xiao Zhao, what are you talking about? Do you have a solution to the 'stoma' problem?" Hearing this, Wang Youchang immediately lost his composure.

"Yes, Director Wang." Zhao Guoyang said in a loud voice.

"Not only do I have a solution to the 'air hole' problem, but I can also solve the 'incomplete penetration' problem of the frame, so that the frame produced by our factory can meet the acceptance standards of Siyang Group."

"Ah! Don't be kidding me!" This kind of news surprised the cadres big and small at the scene. Everyone looked at this young college student with incredulous eyes, wondering if what he said was true or not.

"Xiao Zhao, if you can really solve this problem, the factory will never treat you badly!" Mu Aijun looked at Zhao Guoyang with admiration, and said very boldly.

"Yes, yes, Xiao Zhao, if you can solve the problem of these frames and make Siyang Group agree to use our frames, you will definitely be a great contributor to the factory!" Wang Youchang also said.

Zhao Guoyang didn't write any ink at the moment, and directly stated his solution.

"There are three ways to solve this 'porosity' problem. First, after welding, we need to add a process-remove the welding wire. In addition, the oil, rust, moisture and other sundries on the working groove and the nearby surface also need to be removed."

"Second, use basic electrodes, flux, and dry them thoroughly, and preheat them before welding to slow down their cooling rate."

"Third, when welding products such as car frames in the future, try to use stronger specifications for welding."

"Finally, those frames that have been pulled back for rework are uniformly reversed by DC and welded again with a short arc. After welding, they are re-polished and painted!"

After talking about the solution to the "air hole", everyone was already dumbfounded, and Zhao Guoyang continued to talk about the solution to the "incomplete penetration".

Pointing to the frame beside him, he said calmly: "I have just seen this frame. Generally speaking, the welding process is still 'OK', but there are three 'not penetrated' loopholes."

"According to my analysis, there should be some problems with the groove and gap design, and the angle of the welding rod is not correct. In addition, the welding speed is too fast may also be one of the factors causing this situation..."

"The solution is actually very simple, as long as the welding current is increased and the welding seams are added. In this regard, our welding team leader Liu is an expert, and he can definitely solve this problem."

After Zhao Guoyang finished speaking, he smiled and looked at a gray-haired, thin teacher next to him.

This old man with a yellow complexion and a vicissitudes of life is called Liu Linzhi. He is in his fifties this year. He is the team leader of the welding team of Hongda Machinery Factory. He has been the team leader for more than 20 years.

Hearing Zhao Guoyang's words, Liu Linzhi raised his brows in surprise and said, "Xiao Zhao, you have only been in the factory for a few months, and you don't work hard in our welding team. How do you know so much about the welding process? It really makes me so old. The guy looks amazing!"

After Mr. Liu finished speaking, Zhao Guoyang scratched his head and put on a very low-key posture.

Indeed, the former owner of his body certainly didn't know much about welding, and it was impossible for him to come up with so many targeted solutions.

But who is Zhao Guoyang now? He is the youngest academician-level senior engineer who enjoys special allowances from the State Council. If such a small problem can't be solved, he'll just find a piece of tofu and kill him.

"Well, Master Liu, I didn't say that, I have practiced in a welding factory for a long time, and I know a lot about it."

"Because of this, after coming to our Hongda Machinery Factory, I didn't focus on welding, but wanted to involve as many things as possible that I'm not familiar with, so..."

"Come on, Xiao Zhao, don't be modest. After hearing what you said just now, I can assure you that your welding attainments can definitely catch up with the fifth-level welders in my welding team." Liu Linzhi waved his hand and said.

"Director Wang, congratulations, your technical department has added another elite soldier!" Old Liu said with a smile.

"Old Liu, what do you mean to say, according to Xiao Zhao's method, your welding team can solve the problem of 'incomplete welding'?" Mu Aijun was overjoyed.

Liu Linzhi nodded, raised two fingers, and said with certainty: "Director, don't worry. Xiao Zhao explained the solution to the problem so clearly. If I, an old welder for decades, can't solve it, Then I’m sorry for the salary I got.”

"Two days, give our welding team two days, even if we work overtime, we must rework all the frames that have been brought back!"
