The chief engineer, Kim Hunsan, and a few of the sailors looked at him strangely as the master artisan pulled out a hammer from his toolbox.
Don't look down on this hammer, it was also of superior quality.
After hitting it a few times, the master artisan knew what to do. He then took out a metal needle and poked it into the crack in the shaft.
Then the master artisan took out a few glass bottles from his toolbox, each filled with different colored powders.
This was metal powder, which included steel powder, chromium powder, silicon powder, and nickel powder. Last time Ye Qing went to the metal market, he also bought some metal powder. These metal powders were very cheap, and were very commonly used in modern powder metallurgy.
The master artisan took out these powders because he wanted to use powder metallurgy to repair the shaft.
It was just that the chief engineer and the sailors present were all experts in dealing with machinery. Especially the captain, he had a good knowledge of machinery.
He thought this was nonsense, he only used the needle to determine the crack and then started to mix the metal powders. He didn't even check the shaft's composition or the metal's flaw.
Seeing the master artisan mix the metal powders, Kim Hunsan and the sailors almost fainted.
This man …
He only took a measuring spoon, he didn't even prepare a scale.
For any kind of alloy, the ratio of the metal had to be accurate to 0.0%. This was like making medicine, the more accurate the composition, the better the effect of the medicine.
The measuring spoon was used to measure the ratio, the sailors all agreed that it was no different from grabbing something.
Their mocking laughter came to an abrupt end when the master artisan mixed the metal powders and shook them evenly.
In order to combine the metal powders with the shaft after sintering, the two metals had to be of the same composition. If the composition was the same, then naturally the color of the metal would be the same.
In the glass container, the final metal powder color, no matter how much they rubbed their eyes, they couldn't tell the difference between it and the shaft's color.
Only using the color to distinguish the composition was a very unscientific act.
But the old man in front of them didn't hesitate or think, as if he had practiced this for thousands of times. He used a measuring spoon, not one bit more, not one bit less, to mix the metal color that no one could pick out.
This in itself was a very unscientific behavior that broke their understanding of the world.
What was even more unscientific was yet to come. In order to repair a defect in a part with ordinary metal powder, one would first have to spray the metal powder and then use a high-temperature flame to sintering it.
The Master Craftsman did not spray metal powder first, but started the solid-state laser welding machine, controlled the welding arm of the machine, slowly moved to the crack of the spindle, and let the diamond-like laser focusing lens at the crack of the spindle.
When the orange protective glass was lowered and covered the work area, Ye Qing put on a pair of cool sunglasses for himself.
The chief engineer, Kim Hunsan, and a few of the sailors had already become mutes. What they thought was an ordinary welding machine had proven itself to be extraordinary with its actions.
As the master artisan turned on the high-energy laser, the light of the high-energy laser, even after being blocked by the protective cover, turned the entire engine compartment into a sea of orange light in an instant.
What kind of terrifying laser power was this?
Realizing that the orange light in the engine compartment was not too dazzling, they gathered their courage and turned their gazes over.
A pure white beam of light as thick as a ballpoint pen moved within the orange protective shield at an extremely fast speed.
Hiss ~ Hiss ~ Hiss ~ Hiss ~ Hiss ~ Hiss ~ The sound of metal cracking as it was being heated could be heard continuously. Two minutes later, when the beam of light finished traveling, the protective shield rose.
Everyone could see it. The originally irregular crack on the power shaft had now become an extremely neat rectangle. The magma-like metal flow was quietly lying on the surface of the shallow crack.
A few seconds later, the metal flow cooled down and returned to its original color.
Except for Ye Qing, everyone was dumbfounded.
Because they realized that the crack had become shallower, but also wider.
The terrifying heat from the laser before had melted the metal into liquid and slowly gathered at the bottom of the crack.
While the crack was being filled, it also melted the irregular crack into an irregular rectangle.
It was because of this that the chief engineer, Kim Hunsan, opened his mouth as wide as possible, to the point where he could stuff ten eggs in. They had seen the laser welding machine before, so they also understood the principle behind it. The laser heated the metal to its melting point, and when it cooled down, the two metal objects would naturally be glued together.
But this heating area had a limit, and was also very uncontrollable.
The laser welding machine in front of him had completely shattered his knowledge. The chief engineer, Kim Hunsan, also knew that if he were to be shocked, it would make him seem tasteless and a joke.
But he couldn't control his body. From mockery, to suspicion, and then to shock. Kim Hunsan had completely turned into a bull that didn't know anything, being led around by the nose by the master artisan and the laser welding machine.
The changes in their expressions were all seen by Ye Qing.
In fact, the more you knew, the more you would be shocked and in disbelief by the master artisan's processing skills and the tools produced by the Monster Factory.
The master artisan unhurriedly mixed the metal powder, and evenly sprinkled it into the molten pool created by the laser.
The crack was originally about six centimeters deep, but now it was only one centimeter deep.
After sprinkling the metal powder, the master artisan continued to turn on the laser welding machine, allowing the high energy laser to melt the metal powder into a thin layer of metal solution. After cooling down, the master artisan added more metal powder and repeated the process.
Fifteen minutes later, the last layer of metal powder was sintered.
What appeared in front of everyone's eyes was a main shaft with a slightly rough rectangle of repair marks that could only be discovered when one got closer.
But this rough rectangle was quickly polished by the master artisan with a high power electric mill, becoming a non-existent mark that even the gods couldn't find.
"Impossible, this is impossible." One of the sailors shouted in his native language, "Even Hyundai Heavy Industries couldn't fix the main shaft, how could you guys fix it?"
"Its structural strength must not meet the requirements. It must be so."
Ye Qing did not understand Korean, but Liu Yuanzheng beside him did. At this time, Liu Yuanzheng, who was pleasantly surprised as if he had won five million yuan, translated his words to Ye Qing without missing a beat.
"Why are you so sure that the whole world can't do something that others can't do?" Ye Qing looked at him strangely. "You must have never heard of the saying, 'There's a hierarchy of knowledge, and there's a specialization in every field.'"
"Won't you know once you turn it on?" The Master Craftsman chuckled. It was just an ordinary alloy spindle. With his own skills, coupled with the excellent quality laser welder, if he couldn't even fix it, how could he call himself a monster factory?
Chief Engineer Kim Hunsan's face was full of awkwardness. It was already embarrassing enough, but he didn't think that his colleagues wouldn't believe him. The Hua Xia people in front of him really did have miraculous processing skills.
That godly combination of technology, that extremely advanced laser welder, completely overturned his prejudiced view of this country.
Afterwards, when the engine was turned on, it completely confirmed this point.
Inform the bridge to retract the ship's anchor.
Under his command, the 15,000 horsepower diesel engine, began to make a loud clanging sound similar to that of an old-fashioned train. Under the drive of the gears, the two huge main shafts slowly turned.
The entire engine room clearly felt a tremor. This was the giant ship moving.
Chief Engineer Kim Hunsan and the sailors excitedly stared at the repaired left front shaft. The moment the diesel engine was turned on, the main shaft was subjected to the greatest torque.
Nothing out of the ordinary happened.
Chief Engineer Kim Hunsan informed the control panel to gradually increase the power output.
The 15,000 horsepower diesel engine began to slowly accelerate. Two minutes later, the engine reached its maximum speed, and the sound of the propeller cutting through the water could be heard clearly.
The sailors were so excited that they almost jumped up and high-fived each other in celebration.
Under the maximum torque, the main shaft still didn't have any problems. This meant that the main shaft was completely repaired.
This meant that they didn't have to return to the port and spend a large sum of money to move the containers to another ship. They also didn't have to waste a week waiting for Hyundai Heavy Industries to make a new main shaft.
After telling the control room to lower the power, Chief Engineer Kim Hunsan and a few sailors hesitantly walked over to express their gratitude.
Ye Qing very inappropriately poured a bucket of cold water on them.
"This repair work is only half done!"
"Half?" Chief Engineer Kim Hunsan and the sailors' faces looked like a bucket of negative 10 degrees cold water had been poured over them.
Wasn't the main shaft already working normally?
How could it only be half done?
"We still haven't done the dynamic balancing." The master artisan said with a face full of worry: "The previous crack was a full centimeter wide. This means that the straightness of the main shaft has also increased by a centimeter."
"After the main shaft was repaired by me, its structural strength is no different from the one on the right. But the straightness of the main shaft is only a centimeter. Isn't this a joke? If this was in the manufacturing industry, a centimeter difference would be enough to get you shot. "
When the main shaft cracked, the precision would naturally change.
Chief Engineer Kim Hunsan understood this logic. But to do dynamic balancing, they would need to remove the main shaft and install it on a special inspection equipment. This cost was too high.
If there was an error, there would naturally be wear and tear. Although the wear and tear on the main shaft was very light, but if a centimeter difference wasn't removed in a day, everyone would have a knot in their heart.
Chief Engineer Kim Hunsan originally wanted to wait for the ship's scheduled maintenance before doing dynamic balancing or changing the main shaft.
But if the master in front of him had the skills to do dynamic balancing …
The master artisan asked them to lower the speed of the main shaft. Then he placed one hand on the surface of the main shaft and rubbed it back and forth like a monk patting the head of a believer.
With his other hand, he used a marker to quickly mark a few arcs.
When the main shaft stopped rotating, a few sailors shamelessly squeezed over and used their hands to touch the markings.
A centimeter difference, of course they could feel it. But it was only limited to feeling it. If they wanted to fix it, it would be better to just kill them.
The master artisan raised the excellent quality electric motor machine, eager to try it out.
Chief Engineer Kim Hunsan and the sailors all opened their eyes wide, ready to admire the miracle that this master artisan would bring.
They were completely convinced by the master artisan. They didn't doubt that he could manually fix the straightness of the main shaft and restore it to the acceptable standard.
After all, those top masters could distinguish a 0.03 millimeter difference with their hands. This master in front of them was definitely better.
"There are three ways to set the price of dynamic balance." The master artisan pinched his nose: "Normal dynamic balancing, excellent dynamic balancing, perfect dynamic balancing."
