Taking the copper wire in Liu Linzhi's hand, Zhao Guoyang swept his eyes and nodded with satisfaction.
It can be seen that these copper wires have just been pulled out of the cable, and the appearance is very smooth, which is a good material for copper repair welding.
Zhao Guoyang chose two copper wires of similar length, put them aside, and then picked up the fuel tank that had just been tested.
"Master Zhou, after my fuel tank is repaired and welded in a while, please use a fan to cool it down.
If the copper is burned for repair welding, it is easy to oxidize when cooled with water, and it can only be cooled by air.
Before Zhao Guoyang started welding, he said hello to Zhou Jingfang.
Zhou Jingfang nodded with interest: "Okay, I'll leave this to me."
Actually, I'm more concerned about Section Chief Xiao Zhao, how did you fix this fuel tank?"
Zhou Jingfang's question is also the question of the big guy.
In the early 90s, the domestic welding process was not fully standardized, and many welders actually did not learn too much theoretical knowledge, and they all followed the master to learn little by little.
Zhou Jingfang's welding level should be said to be very good, but in terms of theory, she is still a little worse.
It is rare to have Zhao Guoyang, a person who understands both theory and practice, to demonstrate, and she naturally wants to learn more.
Under the gaze of everyone, Zhao Guoyang turned on the welding machine unhurriedly and began the repair welding work.
He didn't put the copper wire directly on the leaking part of the fuel tank first, but first added a little heat to this place to prevent the weakening of the strength around this place after the repair welding.
Seeing that the temperature was almost heated, Zhao Guoyang picked up a copper wire and put it in the corner of the fuel tank.
Under the high temperature of the welding gun, the copper wire melted quickly, and Zhao Guoyang skillfully rotated the fuel tank to make the melted copper water spread as evenly as possible on the flanges and corners of the fuel tank leakage.
Under the high temperature fusion, the copper water quickly merged with the corner of the fuel tank, which burned to a fiery red.
Then, Zhao Guoyang picked up another copper wire and repaired it at the corner on the outside of the fuel tank.
After a while, the combination of the corner and the flange had been re-welded by Zhao Guoyang.
From the outside, the corners and flanges after welding are slightly thicker than before, but they are still flat.
Almost as long as it is polished slightly, it can be shipped as a finished product.
After fixing a corner, Zhao Guoyang did the same and repaired the remaining seven corners of the tank.
The whole process only took ten minutes in total.
Actually, Zhao Guoyang didn't need to be so troublesome.
Because only one of the corners of this tank had a leak, but to be on the safe side, he reinforced all the corners a little bit just in case.
After the repair welding work was completed, Zhao Guoyang handed the fuel tank to Zhou Jingfang, and said with a smile: "Master Zhou, my work is done, I will trouble you below." ” "Well, don't worry" Zhou Jingfang didn't say much, took the fuel tank and put it under the big fan to cool down.
When Zhou Jingfang was cooling down the fuel tank, Zhao Guoyang turned his head and Wang Youchang said: "Director Wang, after the repair welding, there should be no big problem, and the batch of fuel tanks that have been made can be done according to my repair welding method." ” "As for the fuel tank that hasn't been made yet, Master Hua and I will check the size again in a while and hand it over to the production side again."
When Wang Youchang heard this, his eyes turned to Hua Guosheng.
He already knew the cause of the incident, and he also understood that the problem this time was completely Hua Guosheng's negligence.
But Wang Youchang is a very kind-hearted person, although he is anxious, he doesn't say anything about Su Muzhong, and he is ruthless about Hua Guosheng.
At this time, seeing Director Wang's gaze sweeping over, Hua Guosheng nodded again and again, and said: "Guoyang, don't worry, I have just informed them about the production side, and let them all stop."
When the results of your repair welding come out, I will immediately go and re-size the flange with them. ” Zhao Guoyang nodded, and his attitude towards Hua Guosheng's victory was still positive.
In fact, Hua Guosheng still has a certain level.
The problem this time was also because no one reviewed the plan and drawings for him.
In his previous life, according to the situation that Zhao Guoyang came into contact with.
No matter how awesome the enterprise technology department, every drawing and every plan must be reviewed through four procedures.
That is, design, review, standardization, and approval, these four procedures.
Of course, some more rigorous manufacturers will have an additional approval process after approval.
Usually, those who sign the "approval" order are factory-level cadres who understand the old technical qualifications.
Even with so many procedures, sometimes there are still some mistakes in the technical department.
But this error rate has basically been reduced to the limit, and if something really goes wrong, it is not a problem with this set of programs.
However, in Hongda Machinery Factory, a manufacturing drawing or a manufacturing plan, from the completion of the design to the end, there is only one technician in the work, and the others are only working at most.
It's as if Hua Guosheng's drawings for production this time only went through his own hands, and then it was sent to the production department, and no one else helped to review it.
In fact, Hua Guosheng was also very helpless, he also wanted someone to help him review the drawings and plans, but before Zhao Guoyang showed himself, there was not even one technician in the entire technical department who could review him.
He, a technician, can't go to Wang Youchang, the deputy factory director, to review the drawings for himself In Zhao Guoyang's view, if Hongda Machinery Factory wants to move forward step by step, the review process of drawings and plans must be started.

Among the young people in the technical department, Xu Dongfeng has the best relationship with himself, and he is also smart.
Let's start with him.
If there are any drawings, let him draw a rough picture first, and then let Hua Guosheng review it for him, and finally check it himself, basically this set of processes will not be too many problems.
Just when Zhao Guoyang was secretly thinking about how to reform the technical department, Wang Youchang patted him on the shoulder in fear and asked: "Guoyang, how sure are you in this method of burning copper and repairing welding?"
"If we don't know for sure, we might as well prepare for both.
On the production side, let the director of the horse factory continue to prepare the materials, so that you can be prepared."
When Ma Jian heard this, he smiled and said, "Lao Wang, it seems that you still don't have enough confidence in our Guoyang."
I don't think there's any need to be so troublesome, since Guoyang is so sure, he will definitely be able to handle this repair welding matter.
I trust him unconditionally. ” Wang Youchang didn't expect Ma Jian to have so much confidence in Zhao Guoyang.
He was worried that if he said a few more words, he would inevitably refute Zhao Guoyang's face, and he could only wait for the results of Zhou Jingfang's repair welding
