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

"When I was in college, I had an internship 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 'pores' is common in the industry, and I agree with this. ”

"Because there are indeed many welding factories, in order to save trouble, they don't pay too much attention to this problem. After all, one or two 'porosity' doesn't have much of an impact on the use of most weldments. ”

"But as far as our product is concerned, because its use is the frame of a motorcycle, which is a very important part of the vehicle, the problem of 'pores' cannot be taken lightly. Zhao Guoyang followed the conversation.

Looking at Zhao Guoyang, who has always been silent, talking eloquently without stage fright at the moment, Wang Youchang was full of surprise as if he saw him for the first time.

Mu Aijun and Ma Jian next to him also looked at each other, looking quite surprised.

Zhao Guoyang didn't notice the eyes of several leaders, and continued: "Motorcycles, I believe everyone has a certain understanding, and its core part is the frame in addition to the engine. ”

"Once there is a porosity problem in the frame, it is very likely to cause a reduction in the effective cross-sectional area of the weld, which will reduce the compactness of the frame, and also have a great impact on the load-bearing capacity and fatigue strength of the frame. ”

Speaking of this, 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 'pores' may still be used by other manufacturers and other products, but since we are supporting large enterprises like Siyang Group, and supporting important components such as frames, such problems are absolutely not allowed, otherwise, there will be only one result, which is what everyone sees - returns!"

After listening to Zhao Guoyang's words, Hua Guosheng's face was blue and red for a while.

He has an arrogant personality and has never been very convincing, and at this time, he was trained by a fledgling college student, and he was naturally full of unhappiness.

"Hmph, so you can talk so well, if you don't know, you think you're from the sales department. Hua Guosheng tilted his head and snorted.

"Xiao Zhao, now that everyone knows the problem, can you have a solution to the problem?" said Director Wang.

"Of course there is!" Zhao Guoyang said confidently.

"What? Xiao Zhao, what are you talking about, do you have a way to solve the problem of 'stomatae'?" Hearing this, Wang Youchang immediately became calm.

"Yes, Director Wang. Zhao Guoyang said loudly.

"I not only have a way to solve the problem of 'porosity', but also solve the problem of 'unwelded through' of the frame, so that the frame produced by our factory can meet the acceptance standards of Siyang Group. ”

"Ahh

"Xiao Zhao, if you can really solve this problem, the factory will definitely not treat you badly!" Mu Aijun looked at Zhao Guoyang with admiration and said very heroically.

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

Zhao Guoyang didn't ink at the moment, and directly said his solution.

"There are three ways to solve this 'stomatal' problem. First of all, after welding, we need to add a process - to remove the welding wire, in addition to the working groove and its nearby surface oil, rust, moisture and other debris also need to be removed. ”

"Second, use alkaline electrodes, fluxes, and dry them thoroughly and preheat them before welding to slow them down. ”

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

"In the end, those frames that have been pulled back for rework are uniformly reversed DC and welded again with a short arc, and then re-polished and painted after welding!"

After talking about the solution of "pores", everyone was already dumbfounded, and Zhao Guoyang went on to talk about the solution of "not welded through".

He pointed to the frame next to him and said calmly: "I have just seen this frame, and in general, the welding process is still 'OK', but there are three 'not penetrated' loopholes. ”

"According to my analysis, there are some problems with the groove and gap design, the angle of the welding rod is not correct, and the welding speed is too fast......

"The solution is actually very simple, as long as the welding current is increased, and the welding cover weld can be added. At this point, Team Leader Liu of our welding team is an expert, and he can definitely solve this problem. ”

After Zhao Guoyang finished speaking, he looked at a gray-haired and thin master next to him with a smile.

This scorched complexion, the vicissitudes of life of the old master is called Liu Linzhi, this year is more than 50 years old, is the leader of the welding team of Hongda Machinery Factory, has been the team leader for more than 20 years.

Hearing Zhao Guoyang's words, Liu Linzhi raised his eyebrows and said in surprise: "Xiao Zhao, it is said that you have not been in the factory for a few months, and you are not diligent in our welding group, how can you know so much about the welding process?

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

Indeed, the former owner of his body must not have known much about welding, and it is impossible to name so many targeted solutions.

But who is Zhao Guoyang now? He enjoys the special allowance of the State Council, and he is the youngest academician-level senior engineer, and if such a small problem cannot be solved, he will simply find a piece of tofu and kill him.

"That, Master Liu, I didn't say it, I have been interning in a welding factory for a long time, and I still know a lot about this aspect. ”

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

"Come on, Xiao Zhao, don't be modest. After listening to your words just now, I can guarantee that your attainments in welding are definitely comparable to the fifth-level welders in my welding group. Liu Linzhi waved his hand and said.

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

"Lao Liu, do you mean to say that the problem of 'unwelded through', according to Xiao Zhao's method, can your welding team solve it?" Mu Aijun was overjoyed.

Liu Linzhi nodded, put up two fingers, and said with great certainty: "Factory director, you can rest assured." Xiao Zhao made the solution to the problem so clear, if I, an old welder for decades, can't solve it, then I'm sorry for the salary I get. ”

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