In the crane chief Jin Xunshan, and the strange expressions of several sailors, the master master took out the roots from the portable toolbox.

Don't underestimate this gimmick, the same excellent quality.

Randomly tapping a few times, the master of the exquisite master has counted, and took out the root metal probe, and reached into the gap of the power shaft cracking.

Then the master master took out several glass bottles from the toolbox, which contained several different colors of powder.

This is a metal powder, there are steel powder, chrome powder, silicon powder, nickel powder. The last time Ye Qing went to the metal market to purchase, and also bought some metal powder back. These metal powders are very cheap and are very common in modern powder metallurgy. s material.

The masters took out these powders and naturally planned to use powder metallurgy to repair the spindle.

Only the wheel captains and sailors who are present are also insiders who deal with machinery. Especially the wheel length, it has a good knowledge of machining.

He felt that it was a noisy, just using the probe to judge the crack, began to modulate the alloy powder, and even the detection of the composition of the main shaft, metal detection, these necessary steps are not.

Seeing the master craftsmanship of the metal powder process, the chief engineer Jin Xunshan and several sailors almost fainted.

This person...

Only one scoop was taken, and even the most minimal Scorpio was not prepared.

For any alloy, the metal composition ratio should be accurate to a percentage of 0.0, which is like medicine. The more precise the ingredients, the better the effect produced.

The amount of the scoop used to measure the specific gravity, several crew members agreed that there is no difference between the hand and the hand.

Their ridicule, after the masters match the good metal powder, shakes evenly and stops.

If the metal powder is to be sintered and fully integrated with the main shaft, it is necessary to achieve a high degree of uniformity between the two metal components. The composition is consistent and the color of the natural metal is also consistent.

In the glass container, the color of the metal powder finally matched, even if they polish their eyes, they can't tell the difference between the color of the spindle and the color of the spindle.

It is a very unscientific behavior to distinguish components by color alone.

But the little old man in front of him, without any hesitation and thinking, is as skilled as tempering thousands of times. All rely on a measuring spoon, not a lot, a lot of matching with the metal color that everyone can not pick bad.

This in itself is a very unscientific behavior that breaks their cognition.

Even more unscientific is still behind, ordinary metal powder repair parts defects, need to spray metal powder first, and then sintered with high temperature flame.

The master did not spray the metal powder first, but started the solid-state laser welder, controlled the welding arm of the machine, and slowly moved to the crack of the main shaft to make the laser focusing lens with the top diamond shining, aiming at the crack of the main shaft.

When the orange protective glass was lowered and the work area was covered, Ye Qing brought himself a cool sunglasses.

The chief engineer Jin Xunshan and a few sailors have become dumb at this time, because this equipment, which they originally thought was a common welder, showed their extraordinaryness with practical actions.

With the ingenuity of the high-energy laser, the high-energy laser shines, even after being shielded by the protective cover, the entire power cabin becomes an orange sea of ​​light in an instant.

What a terrible laser power?

It was found that the orange light in the power cabin was not dazzling, and several people bravely turned their eyes.

A pure white beam of round ball refill thickness travels extremely quickly inside the orange protective cover.

滋滋～滋滋～ The cracking sound of the metal being heated is endless. After two minutes, when the beam is gone, the protective cover rises.

Everyone can see it. The original irregular crack on the power shaft has now become a very neat rectangle, and the magma-like metal heat flows quietly on the shallow crack surface.

After a few seconds, the metal heat flow cools back to its original color.

Except Ye Qing, everyone was dumbfounded.

Because they found that the crack became shallower and widened.

The horrible heat generated by the laser before, the metal melted into a liquid and slowly gathered to the bottom of the crack.

While filling the cracks, it also just melts the irregular cracks into a very regular rectangle.

It is because of understanding that the chief engineer Jin Xunshan will open his mouth to the maximum and stuff it into the size of ten eggs. They have seen laser welders and the principles are also known. The laser heats the metal to the melting point, and after cooling, the two metal objects are naturally bonded together.

However, this heating area is limited and very uncontrollable.

In front of this laser welder completely broke his understanding, the chief engineer Jin Xunshan also knows a surprise, it will appear that he is very tasteless, let people see jokes.

But I can't control my body, from ridicule, to doubt, to shock. Jin Xunshan was completely a cow who didn't understand anything. He was led by a master, and the laser welder took his nose.

Their expression changes, Ye Qing is in his eyes.

In fact, the more you understand, the more you will be shocked and unbelievable about the skill of the master craftsmanship and the processing items produced by the monster factory.

The delicate master unduly spreads the prepared metal powder evenly into the molten pool that the laser burns.

The original crack was about six centimeters deep and is now only one centimeter deep.

After the metal powder is sprinkled, the laser welder is turned on, and the high-energy laser melts the metal powder into a shallow metal solution. After cooling, the metal powder is continuously added to repeat the step.

After fifteen minutes, the last layer of metal powder is sintered.

What appears in front of everyone is a spindle that can be found in addition to being close to it, with a slightly rough rectangular patch.

However, this point was rough, and it was quickly polished by the masters using a high-power electric grinder, which became a trace of the gods.

"Impossible, this is impossible." There is a sailor who speaks his hometown and is full of screaming expressions: "There is no way for Hyundai Heavy Industries to repair the main axis. Why can you fix it?"

"It's structural strength must not meet the requirements, it must be."

Ye Qing does not understand Korean, but Liu Yuan is right next to him. At this time, Liu Yuanzheng, who was as big as five million in surprise, translated his words to Ye Qing.

"Those things can't be done by others, why do you know that the whole world can't do it?" Ye Qing looked at him strangely: "There is a sequence of news, and the industry has specialized in this sentence you must have never heard of."

"I don't know when I try it on the boot?" The master is laughing, the main shaft of a common alloy, his own technology, plus the excellent quality laser welding machine, even this is not well repaired, what is the monster factory?

The chief engineer Jin Xunshan was full of shackles on the face. It was already shameful. I didn’t expect my colleagues to believe it. The Chinese people in front of us really have miraculous processing technology.

The gods' matching technology and the extremely advanced laser welding machine completely overturned his previous prejudice against the country.

Subsequent booting has also confirmed this completely.

Inform the cab and close the anchor.

Under his command, the 15,000-horsepower diesel engine began to emit a loud sound like the old-fashioned train. Driven by the gears, the two huge main shafts rotate slowly.

The entire power cabin is clearly felt, this is the huge wheel is moving.

The chief engineer Jin Xunshan and the sailors were excited to stare at the repaired left front axle. The moment the diesel engine started, the spindle was subjected to the largest torque.

No exceptions have occurred now.

The chief engineer Jin Xunshan informed the console and gradually increased the power output.

The 15,000-ton diesel engine began to accelerate slowly. After two minutes, the diesel engine reached its maximum speed. The sound of the propeller breaking through the sea was clear.

The sailors almost jumped up and excited to celebrate each other.

In the maximum torque working state, the spindle still has no problem, which means that the spindle has been completely repaired successfully.

This means that they don't have to return to the port, spend a lot of money to re-transfer the container to another ship, and don't have to delay a week to wait for Hyundai Heavy Industries to rebuild an expensive spindle.

Let the control room reduce the power, the chief engineer Jin Xunshan, led several sailors, hesitantly wanted to come over and express his gratitude.

Ye Qing poured a cold water on them.

"This repair work is only half done!"

"Half?" Chief Engineer Jin Xunshan and several sailors, his face seems to have been poured a basin of minus ten degrees of cold water.

Is the spindle not working properly?

How can I fix it to half?

“There is no dynamic balance yet.” The delicate master said with a worried face: “The previous crack was a full width of one centimeter, which means that the straightness error of the main shaft has also increased by one centimeter.”

"After the spindle was repaired by me, the structural strength is no different from the one on the right. But the straightness error of a spindle is actually one centimeter. Isn't this a joke? This is in the processing industry, and the error of one centimeter is enough to shoot. It is."

When the spindle is cracked, the accuracy will naturally change.

Jin Xunshan, the chief of the machine, understands that it is too costly to remove the spindle and put it on a dedicated inspection device.

If there is an error, it will naturally wear out. Although the wear of the low-speed spindle is very slight, the accuracy error of 1 cm is here, and one day will not be eliminated, and everyone will have a flaw in their hearts.

Chief Engineer Jin Xunshan wanted to wait for the ship to be regularly maintained, then do power balance repair, or replace a spindle.

But if the master has the technology to do the power balance...

The masters let them lower the spindle speed a bit, then one hand on the surface of the spindle, the sorghum stroking the head of the believer, rubbing back and forth on the spindle.

The other hand uses a marker to quickly mark several arcs.

When the main shaft stopped rotating, several sailors shrank over and covered them with their hands.

With a 1 cm error, they can of course feel it. However, it is only limited to feeling. If you want to fix it, it is better to kill them.

The exquisite master is holding a high-quality electric motor with excellent quality, and he is eager to move.

The chief engineer Jin Xunshan and the sailors, all eyes wide open, ready to appreciate the miracle brought by the master.

They have been completely convinced by the masters, and there is no doubt that he can manually restore the straightness of the spindle to the qualified data.

After all, those top-level processing masters used their hands to discern the error of 0.03 mm. The master in front of you is definitely more powerful.

"This power balance, there are three price practices." The master master buckled the nostrils: "normal power balance, excellent power balance, perfect power balance."

"Which one do you want to do?"
