The sparks of the arc splashed, and pieces of scrap iron were welded.

"Bang bang bang bang!" Qin Tao took the small hammer and smashed the welded bulge open, revealing a big hole inside.

"No, next one."

Although he told his father that he wanted to select a group of people to train, Qin Tao had to select a group of excellent people from them, if the welding technology could pass, it would save a lot of time.

Of course, it is very simple to judge whether to pass the test. Most people cannot catch fire after coming up. Those who are eliminated directly and can catch fire. Let’s take a look at the results of welding.

The next workpiece was handed over, and Qin Tao threw it aside: "Next!"

Hey, this is not bad. Qin Tao looked at the welds of the entire workpiece. Although they were not beautiful fish scale patterns, they were welded after all, very evenly. It seemed that they had some effort on their hands.

Qin Tao raised his head and saw Ma Laoliu's face.

"Mr. Qin, how about it?"

"Well, it's not bad. Go there, find Master Zhao, and study hard."

Zhao Changshui has already started to be a master. After all, he welded the catamaran. After all, he was familiar with it. Zhao Changshui can take his apprentice to complete this task with his disciples. He only transferred Zhao Changshui as a skilled worker, which had no impact on the construction of the dredger.

On this day, Qin Tao selected eight people to form a catamaran construction team. He didn't plan to do the high quality anyway, so he let them practice.

The others could only helplessly return to their original workstation and continue to demolish the ship.

That night, the Ship Design Institute also delivered the dredging equipment, and the dredger could complete all the construction work.

Qin Tao looked at the busy construction site and felt a little worried. Why didn't Cong Ju come back as agreed? Could it be that she had encountered some trouble?

However, Qin Tao just thought about it and didn't call him. He knew Cong Ju's personality. Since he didn't come, there must be a problem. Why should he disturb him?

Nie Shiyu has not started school yet, so she would come over to check it out every day, even if she just walked behind Qin Tao and didn't talk, she was very happy.

One day, another day.

On the eighth day of the first lunar month, after the sound of firecrackers, the steel plate of the second catamaran officially began to be cut. The second catamaran, which cost 20 million yuan and the actual cost is less than 500,000 yuan, officially began to be built.

"Mr. Qin, our ship's engine and propeller must be urged quickly." Zhao Changshui was responsible for the construction of the ship. What he was most worried about was the power system.

"Yes." Qin Tao said: "Those people are so slow to do things. Why haven't they delivered it to me yet? Wait, I'll call to urge me."

After saying that, Qin Tao pressed the button of his elder brother. We have money now, so we don’t have to go to the office to make a phone call.

"Uncle Wu, your efficiency is too low. Has the missile boat been removed yet? I am anxious to use the engine, transmission system and propeller inside." Qin Tao came up and complained: "If you don't send me it, it will delay our shipyard contract and you will be fully responsible!"

Selling scrap iron is the second step, I am anxious to ask for the things inside!

A laughter came from the opposite side: "Taozi, if you call me, is it only business? This New Year has passed, so just forget it if you just come to pay New Year's greetings, don't you even call me?"

"Uncle Wu, happy New Year." Qin Tao said casually, then continued: "Send a car immediately and bring it to me!"

A 6621 missile boat has a power system composed of three engines, so it is still OK to disassemble and repair it and create two sets of start-ups. The catamaran cannot stuff the third set into it.

"The car set off the day before yesterday, and now it's probably about to drive to your shipyard."

"What? Why didn't you say it earlier?"

"It's not too late now!" Wu Shengli smiled happily across the street: "If you have time, come to your house..."

"Hey, hey, hey, the signal here is not very good, I can't hear clearly, what are you saying? Hey, hey?"

Wu Shengli put down the phone. This brat was too much. He didn't even have a phone call during the Chinese New Year. Now he still pretended to be a signal and couldn't hang up his phone! As a son-in-law who had no door, it would be too unauthentic to do this?

Qin Tao had already seen the Steyr semi-trailer with a naval license plate, which was moving through the gate of the shipyard. He had known that he would not call him. Isn’t this a waste of his phone bill?

"Ah sneezing!" Qin Tao sneezed. Needless to say, someone must have scolded him behind his back.

I am not free. I am so busy that I am so busy during the Chinese New Year that I finally have pies falling from the sky. Someone comes to give me money, but I can’t refuse it. I look at the factory during the day and work overtime to modify the design drawings at night. Is it easy for me?

Qin Tao felt very wronged.

Steyr rumbled over, Qin Tao climbed into the crane himself, lifted all three systems, and placed them on the bracket aside. Next, he had to repair these two engines.

In this era, ordinary marine engines have V-shaped structures and four-strokes. However, the engine in front of us is different. The cylinders are arranged horizontally, just like building blocks, using two-stroke work methods. In addition, the help of 48 cylinders and turbochargers has enabled it to achieve a power output of 5,000 horsepower.

It can be said that it only has a good indicator of power, and other reliability, lifespan, fuel consumption, etc. are far from comparable to the world's leading marine diesel engines.

However, as for waste utilization, the engines of those dismantled submarines will definitely come in handy in the future.

Qin Tao looked at the cylinder block and cylinder head made of aluminum alloy castings, which were shining in the sun, and his heart was full of expectations. He couldn't let himself down!

Amid the rumbling sound, streams of black smoke came out. That night, the first engine was successfully started, and the second and third units were not easy. Qin Tao was busy and struggled for three days. By dismantling the east wall and repairing the west wall, he finally started the second diesel engine.

Here, the hull has been welded. After installing the two engines, the supporting transmission system and propeller, the hull is almost completed.

This efficiency is really too high!

Especially the new workers, they are busy with energy and busyness. For them, this is related to whether they can continue to stay in the shipyard, have a stable job, and make more money.

"Everyone's work is good." Qin Tao encouraged everyone in time: "It's time to spray paint next. Before spraying, we must polish the weld. This work is very hard, you have to..."

"We are not afraid of hardship!" Ma Laoliu said, picked up the grinder and continued to work.

In front of him, Mu Ma's expectant look seemed to appear again. When he had a long-term job in the shipyard and saved enough money, he could get married. What's the hard work!

Qin Tao doesn't need to mobilize ideologically at all.

At this moment, the elder brother rang.

"Hey, Lao Zhu, don't worry, we will definitely deliver the work with quality and quantity, now the hull is completed."

"What? Only the hull is enough? How can this be? The top is welded and the interior is decorated. Don't worry, it will take a month to complete."

"What? The boss is very anxious? That's fine, so that's it. However, the final payment must be settled and the price cannot be changed."

"Okay, okay."
Chapter completed!
