Luo Rongchang was the first to turn around and rubbed his eyes. Fortunately, he was dodged. It was not a big deal. Qin Zhenhua was right. It was just a matter of a few times. Well, let's see the effect now. What happened?
Is it a big burnt hole or a pile of welding slag?
When I looked over with this thought, I was stunned when I saw Qin Zhenhua's weld seam clearly.
The newly welded seam has the unique luster of metal and sparkles in the sun. Although the weld seam is only two centimeters long, it is clearly visible that the solder joints above have formed fine lines like fish scales. This is actually
The highest level of welding skills, fish scale pattern!
The most standard welding seam will produce this effect, just like pieces of fish scales, even and tight. To achieve this effect, you need at least three years of experience. In addition to the size of the welding current, there is also a welding gun.
It is related to many factors including the angle of the workpiece, the angle and width of the welding gun, the welding speed, the thickness of the workpiece, etc. It is not easy to achieve such a perfect welding effect!
All master craftsmen have to weld conscientiously before they can weld. What about Qin Zhenhua? This apprentice worker has actually accomplished this?
"Almost blinded me, Qin Zhenhua, whoever works with you will be unlucky!" Li Changjiang muttered a few words and leaned over. When he saw the even welds and perfect fish scales, Li Changjiang
He was stunned immediately: "Did you weld this?"
"Yes, Master Li, do you think my diamond is okay?" Qin Zhenhua said.
Just now he said that if people don’t have diamonds, they shouldn’t do porcelain work. As a result, Qin Zhenhua showed his hand. Fortunately, because Li Changjiang and Lao Qin have a better relationship, they didn’t say it too harshly. Otherwise, they would not be able to get back together.
He would be slapped in the face like Liu Jianzhi.
"How did you do it?" Li Changjiang asked. He ignored Qin Zhenhua's question just now. Now, he was more surprised. Qin Zhenhua has only been in the factory for a few days? He hasn't picked up the welding handle yet, right? Why?
Would he suddenly show off his skills like this?
"It's very simple. First, look at the thickness of the steel and choose the corresponding current. This kind of fuel tank will burn through if the current is slightly higher, so I only adjusted the current to 60. The main thing is the skill of the hands. If I want to weld
To get crow's feet, move your hands forward with shaking hands, extending forward about fifteen degrees. In this way, the melted flux and wire can just slip through. When your hands are shaking, you should push the heat flow at the same time, moving at about 15 degrees per second.
The clock is moving forward at a speed of one centimeter, and there is a small arc in front, which is consistent with trigonometric function calculations..."
Who has ever seen welding like this? When it comes to welding, there are so many actual figures cited. When a master guides his apprentices, he relies on experience and hands-on experience. It is like learning a foreign language. Don’t say a word.
After two or three, just rely on your sense of language to know which word to choose.
However, Qin Zhenhua just summed it up!
"That's not what I'm talking about. I'm talking about, how do you know how to weld? How long have you been practicing?"
Qin Zhenhua frowned, as if recalling, and then counted with his fingers: "About three months!"
Three months, to reach this level, is definitely not easy. However, haven't you only been in the factory for a few days?
Where can I go to weld for three months?
"Oh, when I was in the production team, after welding the fuel tank, they called me to the county town. They had a repair shop in the county town, and I helped there for a while."
So that's it! In other words, Qin Zhenhua is definitely not incompetent, he also has a foundation. If he has helped there, practiced, and has such skills, he will be considered pretty good.
Wait, how did he know how to weld when he was in the production team? How did he practice before?
"This technology is almost as good as welding car bodies. In our workshop, there is a tank with a cracked car body. We might as well leave it to Zhenhua to weld it!" Luo Rongchang said.
Nowadays, the turret of the tank is still cast, with a round shape, and it seems to have good bulletproof performance. In fact, the bulletproof ability is very poor, but the body has long been welded.
Tanks in the field army rarely have body damage, but if it is damaged, the field army cannot repair it by themselves. Only the super welding machine in the tank factory can use high current to burn through and achieve perfect welding. In the field,
Only the outer skin is welded, but the inside is still weak and can easily be damaged again.
There is this kind of tank waiting for repair in the workshop now, so let Qin Zhenhua weld it.
Although Qin Zhenhua only welded such a small section, it can be seen from this that his skills are extraordinary. In fact, the structure of thin steel plates is more difficult to weld and requires more effort.
"Then, am I qualified to apply to be a technical expert in the workshop?" Qin Zhenhua asked.
That tank was Luo Rongchang's job. However, he thought to himself that if he welded it by himself, it would not be as beautiful as Qin Zhenhua's welding. After all, not everyone can make fish scales. Luo Rongchang came to repair it.
After joining the factory, I became a lot less familiar with my skills.
"I think it's okay," Luo Rongchang said. Anyway, this month, Liu Jianzhi has been jumping around to get this honor. Qin Zhenhua is Liu Jianzhi's apprentice. If he wants it, then just treat it as replacing Liu Jianzhi.
"I don't have any objections either." Li Changjiang said: "Our maintenance workshop hasn't had a top performer for a long time. If Qin Zhenhua comes up, he might be able to get a good ranking in the competition in the factory!"
Being a technical expert in a workshop is not only an honor, but also a responsibility, because there are also competitions between technical experts between workshops and branches! This is certainly not the kind of competition in that special era.
It's a kind of competition at work.
The two old masters agreed and let Liu Jianzhi be the technical expert in the workshop. When he went out, he would definitely be the last one. Qin Zhenhua was different. In the past few days, he had impressed people.
"Master Liu probably won't be here these days. Qin Zhenhua, just take over Master Liu's class for the time being." Zhao Guodong said, "When you encounter problems, study them with the masters more often."
"Yes, no problem!" Qin Zhenhua was very happy that he, an apprentice worker, had been promoted to a master master, even if he was only a master master for a few days!
"Okay, during work, if you don't work at your own posts, you all come here. What are you doing? Are you working hard?"
These words were said in a very official tone, and the master craftsmen around him were immediately stunned. Next, are they saying that their wages will be deducted because of their poor work attitude?
They raised their heads nervously and saw a middle-aged female cadre they were not familiar with. Zhao Guodong also showed a trace of displeasure on his face. He said to him: "Deputy Section Chief Liu, what brought you here?
