40 Two Problems of Laser Welding (Part 1)
"Ahem..."
"Elder General, what's wrong with you?"
"Maybe I had a cold the night before yesterday and caught a cold... Cough cough... Xiaofeng, let's stop talking about this today."
"Don't you beating? Do you want me to call a doctor?"
"It's okay, I have medicine in my drawer. You go quickly, I'm afraid it will spread to you."
"But the royalties and salary have not been negotiated yet?! I think it would be better to discuss this kind of thing clearly in advance."
"I'm so sick, ah... how can I talk about it later."
Bang...
The office door is closed.
Looking at the cold door, Lin Feng was stunned for a few seconds, and four words unconsciously appeared in his mind.
"Damn, ruthless."
Isn’t it just a little royalty, as for pretending to be sick?
He pretends to be so similar, and his acting skills are comparable to those of the old actors.
As expected, the older a person becomes, the more he becomes rogue he becomes.
But in the face of Lin Guoxiang's trick, Lin Feng had no choice for a while.
He was secretly competing in his heart, and he couldn't just let it go. He had to find the scene back, otherwise he would be too frustrated.
.............
Back at Xiaofeng Mecha Company, Zhao Feifei and Zhao Yong came forward first.
Seeing that there were a few red spots on Lin Feng’s forehead, Zhao Feifei asked with concern: “Boss, you are injured, are you okay?”
Lin Feng waved his hand without any worries, "It's okay, I just rubbed it a few times when I was testing [The Legend of the Condor Heroes] for training."
Zhao Feifei stood on tiptoe, looked carefully at Lin Feng’s forehead and pouted: “Boss, your bruise has not yet healed yet, I’ll buy you some medicine…”
After saying that, Zhao Feifei hurriedly left the office.
"Hey..." Lin Feng was about to call Zhao Feifei, but was stopped by Zhao Yong.
"Brother Lin, it's okay. My sister's biggest advantage is that she likes to care about others. Just be fine if you get used to it."
Like to care about others? And this is also the advantage? Why haven’t I discovered it before?
Lin Feng was confused, but was interrupted by Zhao Yong's exaggerated laughter:
"Hahaha, Brother Lin, I have watched all the videos of this battle. The [Sky Destiny] you drove is just one word, handsome. Especially that beautiful tackle is a stroke of magic. If our national football team had such tackle skills, they would probably win the World Cup championship."
Lin Feng was speechless. He was just about to thank him and was blocked in his throat and swallowed it back into his stomach.
"Brother Lin, your battle has been cleared for [The Legend of the Sky]. Now all the praises of [The Legend of the Sky] are all on the Internet. In the Mecha Post Bar, [The Legend of the Sky] originally had only a few hundred fans, but it soared to more than three million in one day."
Lin Feng couldn't help it: "Brother Zhao, you are the boss after all, and you still have the intention to go and have a job?"
"Yes!" Zhao Yong's expression changed and he suddenly became melancholy. "I am the boss, but I am the boss who does the monster business. I'm almost bankrupt when the monster hasn't arrived for several months."
Speaking of this, Zhao Yong changed his mind and looked at Lin Feng, and asked mysteriously: "Brother Lin, can you ask the old general, and sell me the body of the sickle head?"
Well, I talked for a long time, but it was still for the monster corpse.
Lin Feng shook his head decisively, "Don't worry about the corpse of the sickle head. As the first invading fourth-level monster, scientists from the South China Sea branch must use the corpse of the sickle head for research."
"Oh!" Zhao Yong responded in disappointment.
"Brother Zhao, if nothing else, I'll go to the factory first."
"Okay, I'll go with you."
......
"Hello, Mr. Lin, and Mr. Zhao!"
"Mr. Lin is here... Hello Mr. Zhao!"
"Mr. Lin, you're back. We're all waiting for you to guide your work...oh, Mr. Zhao."
The workers' attitudes towards the two are different.
The way Lin Feng and Zhao Yong replied to greetings was different.
Someone greeted him, but Lin Feng nodded with a smile and acted very kindly.
Zhao Yong, on the other hand, held his hands behind his back, raised his head and chest. When others greeted him, he just hummed with a nose to express his response, which was very cold.
After walking just a few short steps, Zhao Yong couldn't help it. He pulled Lin Feng's arm and whispered: "Brother Lin, you can't do this. You are the boss. You should be more serious, otherwise the workers will not be afraid of you and will not work seriously."
But Lin Feng seemed to have not heard it, and his eyes were focused on each workbench.
Zhao Yong still wanted to persuade him, but when he turned around, Lin Feng had already gone to workbench B-135. Seeing this, Zhao Yong looked helpless and could only take two steps to follow.
B——On the 135 workbench, an HBC-115 handheld laser welding machine is working on the mecha dorsal spinal neuron transmission electronic board.
The mecha designed by Lin Feng requires a total of 1,324 such electronic boards.
Both workers operated correctly, and there was no error, but strangely, there was a lot of electronic boards that failed to process in the scrap box.
Lin Feng walked forward and couldn't help but pick up a scrap electronic board and look at it.
Lin Feng's actions made both workers a little nervous. They had been processing electronic boards for two days, and the scrap rate exceeded 80%.
Improper operation? Impossible? They are all old workers and are very familiar with laser welding. It is impossible to make such low-level mistakes.
Is there something wrong with the machine? No, this is a new machine, how can there be a problem?
So what exactly is the reason? The waste rate during processing is so high?
Yesterday, a technical supervisor Hao came to check it out and studied it for three hours. He didn't even bother to eat lunch. He kept squatting on the workbench to find the key to the problem. He also processed several electronic boards by himself. Unfortunately, the scrap rate he processed was higher than that of two workers.
For this reason, Superintendent Hao and other supervisors met and everyone studied and studied the reasons together.
Unfortunately, several supervisors thought about it all night but couldn't solve it. They had to let the workers process it first. Although the scrap rate was relatively high, the amount needed was not too much, and the losses should not be large.
At this critical moment, Lin Feng is back.
Several supervisors found that Lin Feng was surrounded by the B_135 workbench unconsciously.
"Mr. Lin, is it a problem with machine operation?" Manager Hao asked in a low voice.
Because he does it by himself, the scrap rate is higher than that of workers, and it is easy for people to think about operating standardization.
Lin Feng put down the scrap electronic board, calmed for a moment, and shook his head: "No!"
"Is that a material or machine problem?" another technical supervisor asked.
"Not!" Lin Feng answered very affirmatively.
"What's the reason?" All the supervisors were confused.
Lin Feng stood up, stretched out his two fingers, and replied: "There are two main problems."
Two? Several supervisors looked at each other, and while they were shocked, they couldn't help but calm down and listen to Lin Feng's next explanation.
"The reason for the first problem is the voltage problem."
A technical supervisor didn't understand and asked directly: "The standard voltage of this machine is 220V and the three-phase voltage is 380 volts, which is very consistent with the electricity voltage used in our factory."
Lin Feng shook his head, "It's the voltage frequency. This machine is a product from Donghan. Their rated voltage frequency is 60HZ, not 50HZ in our country. If this frequency changes are processed, it is impossible to see if it's processing ordinary parts, but when processing our electronic board, the problem is very obvious."
Voltage frequency can cause uneven frequency of laser emission, resulting in uneven welding surfaces, affecting the signal transmission of the circuit.
This situation is rare, but it is not absolutely none.
However, in the past, problems found in the rated voltage were generally found in the voltage and power. Because the rated voltages in various parts of the world are different, this problem is caused.
Voltage frequency..., these technical supervisors have never thought about this.
