Although everyone knows that it is impossible to find suitable welding materials and processes so quickly, the continuous failure of various tests still makes everyone feel depressed. No one wants the work they have worked hard to complete to disappear in an instant.
This is what experiments are like. Without countless shatterings, where would the brilliance come from?
Although failure is a failure, it opens the way and lays the foundation for success.
The road to success proceeds step by step like this, with countless welding rods turning into crystals of condensed steel plates in the light of the fire, reuniting the two steel plates into one, becoming a whole.
In the ruptures one after another, various materials were rejected, and new materials were reused to verify whether they could bear the heavy responsibility of the Blue Whale.
After countless experiments, the welding rod residue piled up like a mountain in the experimental site, and the experimental workers were too tired to lift their arms. Even the experienced Zhao Jingfu was exhausted.
The test site was brightly lit at night, and everyone sat there in groups to rest, looking tiredly at the broken steel plates, wondering when this seemingly futile experiment would end.
"Squad leader, how long are we going to do this!" Such a long time has passed. Although some materials are almost close to the target, they are still just one step away. In the past, they would have been enough to meet the welding requirements, but
The Whale Dream Project is different. Not to mention that the difference is just one step, even if the pressure is only one pa, it can never be used on the Blue Whale.
"Work until you find the welding materials and processes that are most suitable for the Blue Whale!" Zhao Jingfu said with firm eyes.
To be honest, he himself did not expect this matter to be so difficult. He had seen the hardships Hong'an Steel went through when developing F690, but he did not expect that it would take so long to find suitable welding materials.
Everyone was silent. They also knew that this was their task and their responsibility. If the key points of welding F690 could not be found, the Blue Whale would be just a pile of steel plates. This would undoubtedly be a huge problem for Fuhai Group.
blow.
"We must find it no matter what!" Zhao Jingfu waved his arm.
"Yes, we must find it!" One after another voices rippled in the experimental factory.
Just when everyone was working hard and preparing to continue their efforts, a sound of footsteps came from outside the gate of the test site. Everyone looked back and saw Wei Yuhui, who had just returned from the laboratory, walking in lightly.
"Old Zhao! There's good news and bad news, which one do you want to hear first?" Wei Yuhui's attitude when talking to Zhao Jingfu during this period was also very different. There was a hint of naughtiness in the seriousness, and the workers were used to it.
It's just that this time it seems to be more provocative.
Zhao Jingfu didn't notice anything. He only cared about hearing the "good news" from Wei Yuhui!
There is good news after such a long time. This is obviously a major breakthrough. I just don’t know where this good news comes from.
"What's the good news?" Zhao Jingfu stood up and asked happily.
Wei Yuhui laughed and waved the experimental data sheet in his hand, "What do you think?"
"Hurry up, I'm almost exhausted. I don't have time to tease you!" Zhao Jingfu couldn't laugh or cry, so he quickly handed over his hands and said.
Wei Yuhui also saw the tired look of the disgraced Zhao Jingfu, and smiled again and said: "Okay, I won't tease you anymore. This is the stress data I just got! Take a look!"
Zhao Jingfu looked at the data sheet handed over by Wei Yuhui, took it over and read it carefully.
It didn't matter. Zhao Jingfu burst out laughing. While laughing, he waved the data sheet in his hand and shouted: "The pressure data meets the standard? Is the data correct?"
"Of course it is correct. We did three pressure tests in a row and the results were the same!" Wei Yuhui said.
"Does this mean we have found a suitable welding material?" Zhao Jingfu immediately turned his attention to the pile of residue that had just been welded. Unexpectedly, the real welding material was hidden here.
When they heard that suitable welding materials had been found, the workers in the test site were instantly excited. The fatigue of the past few days was swept away, and they all gathered in front of Zhao Jingfu.
"Squad leader, have we succeeded?" everyone asked one after another.
Zhao Jingfu stared at the data table and smiled, looking like the silly son of a landlord.
But at this time, Wei Yuhui gave him another head-on cold water blow.
"Why don't you ask what the bad news is?"
Only then did Zhao Jingfu remember that there was still bad news waiting for him, but since the pressure data had reached the standard, this bad news couldn't be any worse, right?
"What bad news?" Zhao Jingfu asked with a smile.
"We found pores in the center of the steel plate!" Wei Yuhui handed over another test form in her hand.
Zhao Jingfu was stunned. The appearance of pores was obviously abnormal. Even if the weld seam could withstand sufficient pressure, the appearance of pores would cause problems with the strength and toughness of the steel plate, and ultimately cause structural damage to the entire steel plate. This was very
Fatal things.
Something was wrong with Zhao Jingfu's eyes when he looked at Wei Yuhui. How could this be bad news? It was like a bolt from the blue!
If you can't find a suitable welding material, you can continue to experiment with the remaining welding materials until you find the right welding material. However, the appearance of pores means that there is a deviation in the welding process. This deviation can be in many aspects.
Caused by.
Temperature, current, voltage, as well as the worker's technique and operating proficiency may all cause the appearance of pores.
With so many factors, finding the cause is no easier than finding welding materials. More importantly, every adjustment requires a lot of time and energy.
Zhao Jingfu frowned after reading the test form, and then asked with a dark face: "Have problems been found in other steel plates?"
"Not yet. Only a small number of them had the same pores just now, but because the pressure was not reached, everyone ignored it!" Wei Yuhui did not hide this negligence of hers.
Zhao Jingfu didn't care to pursue these things. He immediately searched according to the picture and found the detailed data sheet of the original welded steel plate. It contained detailed data of the entire welding process and even the signature of the welding personnel.
Zhao Jingfu took a look and saw that the welding of this steel plate was done by an old worker in the class. His welding skills were considered outstanding in the factory and there should be no low-level mistakes.
"Lao Wang, let's do the welding again, Lao Liu!" Zhao Jingfu decided to send the three most skilled people in the team to see which step the problem might occur.
