"I have welded many ships, bloated cargo ships, long Panamax ships, and huge Cape of Good Hope, which is never welded this type of ship." Cong Ju said to Qin Tao while walking.

"Below it are two compensatory sheets, the middle is a high-rise main hull, and there is a special V-shaped structure below the hull." Cong Ju said.

"This is called high-speed wave-penetration body. The unique structure we designed can reduce the resistance of water on the one hand and greatly increase the speed of the ship. On the other hand, it is to improve the wave resistance of the hull. By increasing the frequency of sway, it can reduce the lateral shaking of the hull." Qin Tao said: "The welding of the two pieces is a difficult point."

"Yes." Cong Ju said: "My body is relatively thin, so it should be the most convenient for me to get in and weld it. However, Master Zhao refused. He insisted on doing it himself and asked me to guide him. The inside was too narrow. He could only take off the coat outside and wear a single coat. He could not wear protective gear. He took a glass sheet that blocked ultraviolet rays and went in. Every time he came out, his whole body was black."

Cong Ju sighed very much that the workers here were deeply moved by her dedication to their work.

"Uncle Zhao, you are so old, why are you still trying so hard?" At this time, the two had already walked to the dock. Qin Tao saw Zhao Changshui and immediately criticized him.

"The other Cong Gong is here to be our master. She guides us. We have to do the real welding. Otherwise, if Cong Gong leaves in the future, we will be blind." Zhao Changshui said: "Besides, Cong Gong is a girl and cannot get in and suffer. She is our guest."

Cong Ju shook her head helplessly. Of course she knew the care of these masters.

"By the way, the welding quality is fine, right?" Qin Tao asked.

"Well, we've all checked it carefully." Cong Ju said, picking up something from the side: "If you are worried, you can see it yourself."

If a ship is built for foreign countries, people will definitely send special quality supervision personnel. However, this catamaran passenger ship is a project of the Navy after all, and it has specially set up a bag company to sign the agreement in the name of civilians. In this way, the Navy cannot send representatives of the factory, so the quality is completely controlled by the shipyard itself.

In the past, when shipbuilding was supervised by the shipyard, everyone was very comfortable.

Qin Tao looked at the thing, it was a long iron wire. At the end of the iron wire, a small mirror was tied to the point where the head could not be reached, and then the quality of the weld was observed.

All welding standards are as Cong Ju said, without any reduction. If there is any problem, you have to rework meticulously.

Qin Tao looked at the shaking lens: "The wisdom of the working people is endless."

"Now, it's just a short time for the engine and water jet thruster. If we install these equipment in place, we can weld the above deck." Zhao Changshui said: "Taozi, when will these equipment arrive?"

Shipbuilding is different from car manufacturing. The shell can open a special engine cover and you can install the engine any time. The hull is welded, and the marine engine is relatively huge.

Therefore, when welding, a huge gap is needed to be left on the deck to lift the engine. After the engine is installed, the hole is welded. For this kind of small boat with a few hundred tons, the deck will not be welded at first, and the engine and the matching water spray thruster are installed, and then welded.

If the process is wrong, there will be big trouble. For example, A San built his own aircraft carrier and went into the water several times. One of them was to cut the top deck and then stuff the engine into it. Of course, only A San could do this kind of operation.

"I'll urge you again, it will probably take a while..." Before Qin Tao finished speaking, a Steyr trailer roared and started on the road in the distance.

After the opening of the country, there were huge gaps in all walks of life, so they were introducing foreign technologies to develop.

The same is true for the truck industry. I originally wanted to introduce Mercedes-Benz, but the Germans were very arrogant and drove out quite harsh conditions. So the inspection team had to switch routes to Austria, a small country, and brought Steyr trucks back.

This is a heavy truck like the Old Yellow River. It has advanced technology and low fuel consumption. After it was introduced, it immediately became the most outstanding heavy truck in China. It has spread across the land of the motherland. Most trucks in decades later still use Steyer technology.

This is a full trailer. On the main car, there is a large wooden box and on the rear hanger, there is a same box. For a full trailer that can overload hundreds of tons and is known as the train sheath on the road, this weight is drizzle.

Qin Tao's heart started beating.

These two big boxes must be MTU diesel engines!

"Sister Cong Ju, do you know who is the fastest running person in the world?"

"Hek Drexler."

"What?"

"West Germany sprint and long jump champion."

"Sister Cong Ju, I didn't expect that I was still a sports fan, but it wasn't her."

"Who is that?"

"Cao Cao."

"What?"

"Speak of Cao Cao, Cao Cao will be there." Qin Tao said.

Cong Ju still didn't laugh. It seemed that she had told a cold joke.

The Steyr truck drove directly to the boat platform. At this time, Cong Ju put all her thoughts on the two MTU engines.

The world's most famous marine diesel engine is useful even if it reaches a cargo ship worth hundreds of thousands of tons. Although it cannot be used to drive a ship, it can drive a generator set for the ship.

However, this is the first time that this engine has been used on a speedboat worth hundreds of tons.

When the car stopped, Guo Jiamin jumped out of the co-pilot.

"Secretary Guo, your actions are too fast, thank you." Qin Tao said excitedly.

"A batch of MTU diesel engines arrived. We coordinated with the railway side. The railway was very generous, so we even gave two of them from their orders." Guo Jiamin said: "This is the first time you have installed this kind of diesel engine. Don't worry, read the instructions for this diesel engine to avoid installation problems."

"No, crane, where is the crane? Get ready to lift the engine! Everyone gets on the car and opens the box. Let's install the engine today!"

The engine has the largest size. If the water jet thruster cannot be in place, you will not wait. Once the engine is installed, the deck can be welded.

The wooden box was opened, revealing the sky blue engine, with eight huge cylinders on both sides, which looked very spectacular. Two huge turbochargers stood in the front, like two big snails.
