Luo Rongchang was the first to turn his head and rub his eyes, fortunately, it was flashed, it was not a big deal, Qin Zhenhua was right, it was indeed a matter of a few clicks, well, let's see the effect now, is it a big hole burned, or a pile of welding slag?

When he looked over with this thought, he saw Qin Zhenhua's weld clearly, and he was immediately stunned.

The weld that has just been welded, with the unique luster of metal, shines in the sun, although the weld is only two centimeters long, but it is clearly visible that the solder joints on it have formed a fine line like fish scales, which is actually the highest level in the welder's craft, fish scale pattern!

The most standard weld, out of such an effect, like a piece of fish scales, even, tight, want to achieve such an effect, at least three years of master, in addition to the size of the welding current, as well as the angle between the welding gun and the workpiece, the angle and width of the welding torch, the welding speed, the thickness of the workpiece, etc., many factors related, want to weld into such a perfect effect, it is not easy!

The masters have to be serious about welding before they can weld it, what about Qin Zhenhua? This apprentice, actually did this?

"Almost blinded me, Qin Zhenhua, whoever works with you is unlucky!" Li Changjiang muttered a few words, and also leaned over, when he saw the uniform weld and the perfect fish scales, Li Changjiang was stunned: "This is what you welded?" ”

"Yes, Master Li, look at my diamond diamond, it's okay, right?" Qin Zhenhua said.

Just said that people don't have diamonds, don't do porcelain work, as a result, Qin Zhenhua showed his hand, fortunately, because the relationship between Li Changjiang and Lao Qin is better, he didn't say it too much, otherwise, he wouldn't be able to come back, and he would be like Liu Jianzhi who was slapped in the face.

"How did you do that?" Li Changjiang asked, he ignored Qin Zhenhua's question just now, and now, he was more strange in his heart, Qin Zhenhua, only a few days after entering the factory? You haven't taken the soldering handle yet, have you? How could you suddenly show such a hand?

"It's very simple, first look at the thickness of the steel, choose the corresponding current, this kind of fuel tank, the current is slightly larger will burn through, so I only adjusted the current to sixty. The main thing is the work of the hands, if you want to weld out the crow's feet, the hands should tremble forward, extend forward about fifteen degrees, so that the melted solder and welding wire can just slip through, and when the hands are shaking, at the same time push this heat flow, at a speed of about one centimeter per second, there is a small arc in front, here is in line with the trigonometric operation..."

Who has ever seen such a weld? Speaking of welding, there are so many actual figures? The master takes the apprentice, relying on experience, the experience in the hand, this is like learning a foreign language, don't say one, two or three, as long as you rely on the sense of language, you should know which word to choose.

However, Qin Zhenhua just summed it up!

"I'm not talking about this, I'm saying, how do you know how to weld? How long have you been practicing? ”

Qin Zhenhua frowned, as if he was reminiscing, and then counted it with his fingers: "Probably, three months!" ”

Three months, to this level, it is definitely not easy, but haven't you been in the factory for a few days?

Where to weld for three months?

"Oh, when I was in the production team, I welded the fuel tank, and they called me to the county seat, where I helped for a while."

So that's it! In other words, Qin Zhenhua definitely doesn't know anything, he also has a foundation, if he has helped and practiced there, and has this kung fu at hand, it will be considered good.

Wait, when he was in the production team, how did he weld? How did you practice before?

"This technology, the welding car body is almost the same, in our workshop, there is a tank body that is broken, simply, hand it over to Zhenhua to weld!" Luo Rongchang said.

Now, the turret of the tank is still cast, the shape is round, and it looks like it has good elastic avoidance, but in fact, the bulletproof ability is a mess, but the hull has long been welded.

The tank of the field troops, there are few damage to the hull, but if it is damaged, the field troops themselves can not repair it, only the super welding machine in the tank factory, with a large current can be burned through, to achieve perfect welding, in the field, only weld an outer skin, the inside is still virtual, it is easy to be damaged again.

Now there is this kind of tank waiting to be repaired in the workshop, so he simply let Qin Zhenhua weld it.

Don't look at Qin Zhenhua only welded such a small section, but this point can be seen that his technology is not ordinary, in fact, the structure of thin steel plates is not easy to weld, and it is more difficult to test kung fu.

"So, am I eligible to apply to be a technical expert in the workshop?" Qin Zhenhua asked.

That tank is the work in Luo Rongchang's hands, but he thinks about it himself, and he welds it himself, which is not as beautiful as Qin Zhenhua's welding, after all, not everyone can do the fish scale pattern, and after Luo Rongchang came to the repair shop, his hands have become a lot more rusty.

"I think so." Luo Rongchang said. Anyway, this month, it has always been Liu Jianzhi who is jumping to get this honor, Qin Zhenhua is Liu Jianzhi's apprentice, he wants it, then it can be regarded as a replacement for Liu Jianzhi.

"I'm okay with that." Li Changjiang said: "Our maintenance workshop, we haven't had a top player for a long time, Qin Zhenhua has gone up, maybe he can still get a good ranking in the big competition in the factory!" ”

Being a technical expert in the workshop is not only an honor, but also a responsibility, because the technical experts between the workshops and the branches must also hold a big competition! Of course, this is not the kind of rush of that special era, but a kind of competition at work.

The two masters agreed, let Liu Jianzhi be the technical expert in the workshop, and when he went out, he must be the penultimate one, Qin Zhenhua is different, these days, it is impressive.

"In the past few days, it is estimated that Master Liu will not come, Qin Zhenhua, you will temporarily take Master Liu's class." Zhao Guodong said: "When you encounter problems, study and study with the masters. ”

"Yes, no problem!" Qin Zhenhua is very happy, he, an apprentice, has been promoted to a master, even if it is only a master for a few days!

"Okay, during work, you don't work in your own positions, you all gather here, what are you doing? Is it grinding foreign workers? ”

This is full of officialdom, and the teachers around him are suddenly stunned, and then, does it mean that because of a bad work attitude, they will deduct their wages?

They raised their heads nervously, and saw a middle-aged female cadre who was not very familiar, Zhao Guodong's face also showed a trace of displeasure, and he said to the other party: "Deputy Section Chief Liu, what wind blew you over?" ”
