Yu Changhong was very devastated.

In the past, he had never welded such a thick armor steel, and he knew that it was not easy to weld, but now that Qin Zhenhua had done it, this made him be slapped in the face.

Since Qin Zhenhua can do it, then he can also do it, with such an idea, Yu Changhong started welding, but it can't be welded, the virtual welding and slag welding in the front are mistakes, and they can be endured, and the ones in the back have obviously tried their best, but the result is still not welded, and they can't be burned through, what's going on?

The same welding machine, the same welding handle, the same welding rod, how did he do it?

Yu Changhong knows that he is already embarrassed, but it is not terrible to be embarrassed, you must figure it out, otherwise every time you meet in the future, you will not be able to raise your head, people can crush yourself to death with a word, you can't do electric welding skills!

What the hell is going on?

"That's right, Qin Zhenhua, how did you do it by welding such a thick steel plate?" Zhou Xuejun also spoke, Yu Changhong is a master, the welding skills are good, Zhou Xuejun knows, now Zhou Xuejun can't do it, Qin Zhenhua actually did it, this is unbelievable!

"Process issues." Qin Zhenhua said.

Craft? It's all welding, what else is the process, if you say, your welding skills are higher, maybe I can still accept it! Yu Changhong was surprised.

"I've read foreign sources, and when they are welding armor steel, one of the processes is preheating." Qin Zhenhua said: "The steel plate is preheated first, and then welded, so that better welding results can be obtained. ”

Electric welding, actually have to preheat the steel plate? I haven't seen this before, besides, have you warmed up?

"Understood, you start with gas cutting, then grinding with a grinding wheel, and then start welding, without a pause, so, it's equivalent to preheating?" Song Weize said.

Qin Zhenhua did not preheat with great fanfare, but hid the warm-up in the first steps, if he didn't say it, who would have known, it turned out that it was warm-up?

Welding steel plates, actually have to be preheated in advance, this operation step, I have never seen it!

However, this is really the case, Yu Changhong took Qin Zhenhua's scraps to weld, at that time the steel plate was already cold, and it was welded directly, and the result was that it could not be burned!

"I'm so hungry, I'm going to eat." Qin Zhenhua said.

After a busy morning, I really feel a little hungry now.

"Let's go, Qin Zhenhua, I'll take you to the cadre canteen." Song Weize said.

"No, that's not good, I can't make an exception." Qin Zhenhua shook his head: "I'm just an apprentice, and it would be good to be able to eat in the staff canteen." ”

Song Weize was embarrassed again, this Qin Zhenhua is really holding a grudge, well, it is estimated that he is also disarming himself, in the future, this guy will go to the R&D room, it must be difficult to manage, but there is technology!

He looked at the machine tool here, his eyes showed joy again, find a forklift, fork this machine tool, fork to the R & D room, it was originally the R & D room, and now it is also the original owner!

I knew that Qin Zhenhua was so powerful, so I didn't say those words at first, but as a leader, this posture is enough, right? This kid, like his old man, is arrogant.

"Brother Zhenhua, you are so powerful!" Walking on the way to the cafeteria, Wang Erzhu admired Qin Zhenhua so much, just after the official start of the game, Wang Erzhu left the competition area and waited in the outside area, and also witnessed Qin Zhenhua's miracle.

"Erzhuzi, study hard, knowledge is power, the factory of the future, only workers with knowledge can control, the West has begun to popularize CNC machine tools, in our place, or zero breakthrough." Qin Zhenhua said: "If I go to the library in the future, I will have to read more books." ”

When he said this, Qin Zhenhua patted his head violently, not good!

"Erzhuzi, hurry up now and go to the library." Qin Zhenhua said.

Library, what? Wang Erzhu touched his head, and Qin Zhenhua couldn't help but pat it twice: "It's not you kid, you promised two female classmates, saying that you want to go to the library this Saturday?" Busy with the big competition, forget about it, you go over, talk to people. ”

If it weren't for Wang Erzhu's promise, Qin Zhenhua would not have agreed, but as long as he agreed, then he had to do it, Qin Zhenhua was a promise, and now, because Wang Erzhu had dragged down his reputation, of course he had to let him run.

Wang Erzhu also remembered that there was such a thing!

In the library, quietly, Wang Xiaoyu sat by the window, looking down at the book, but she was a little absent-minded, looking up from time to time and looking at the window over there.

Those big watery eyes were full of anticipation, and the long eyelashes were more and more disappointed as the eyelids kept turning.

It's already afternoon, and he hasn't shown up yet, and he still has a lot of questions at hand, waiting to ask him.

"Hmph, don't keep your word." The golden flower on the side whispered: "This kind of person is unreliable!" When you make a promise, you just move your lips and quickly forget about it. ”

"Jinhua, don't say that, they must have been delayed because of something, after all, it's not as convenient as us, they are workers." Wang Xiaoyu said.

"You've spoken for them." Huang Jinhua said: "It doesn't matter what the reason is, if he doesn't come, he doesn't come." ”

At this moment, on the other side of the window, a head was exposed, and Wang Erzhu was covered with sweat and climbed in along the window.

"It's coming!" Wang Xiaoyu was happy for a while, but soon disappointed again, Wang Erzhu climbed in alone, and did not follow others.

"Yes, I'm sorry, Brother Zhenhua participated in the factory's skills competition today, so I can't come over." Wang Erzhu stammered a little.

"Hmph, find a reason. At your age, can you still participate in the factory's skills competition? ”

"I can't do it, Brother Zhenhua is amazing, he is the number one!" Wang Erzhu is not stuttering now, Brother Zhenhua, he must not be despised by others.

"Bragging again." Golden Flower is absolutely not convinced.

Wang Xiaoyu quietly pushed her, signaling her to stop talking, and then whispered: "He really won the first?" ”

"Of course, the entire factory is estimated to have spread now, Brother Zhenhua's big competition today, it is out of the limelight." When Wang Erzhu said it, he came to the spirit, and he didn't even have time to find his favorite comic book.

"Later, the director of the R&D room of our factory invited Brother Zhenhua to enter the R&D room, but Brother Zhenhua did not agree, and put forward conditions with him, our factory, only Brother Zhenhua is so good!"

"So, this week, he won't come?" Listening to Qin Zhenhua's performance, Wang Xiaoyu was very happy, but still a little disappointed.

"Next week, I'll definitely bring him next week, or, tell me my home address, and I'll let Brother Zhenhua go to your house to find you?"
