The task undertaken by Zhao Jingfu's team sounds very simple, which is to weld huge steel plates into pontoons and columns. There are neither complicated pipelines nor huge equipment and machinery, and there are almost no very difficult operations. However, these are just plain-looking things.
The steel plate is the real difficulty.
In welding engineering, a steel plate exceeding 20 millimeters is considered a thick steel plate, and it is even rarer to see more than 50 millimeters. Each of these steel plates in front of you has a thickness of 100 millimeters, which is even thicker than an adult's palm. Such a thick steel plate
The difficulty of welding has skyrocketed, and the time and physical strength required are also extremely huge. Moreover, this welding is related to the quality of the Blue Whale, so it cannot be sloppy.
Zhao Jingfu raised his head and glanced at the wall clock on the pillar. It was only a few minutes before work started. He immediately shouted: "Come here, let's have a pre-shift meeting!"
Hearing Zhao Jingfu's voice, workers around the site quickly came to him in twos and threes.
"Today's task is to weld the bottom plate of the pontoon. Although it seems simple, the technology is not easy. Now the pre-treatment workshop has sent the steel plates. Wait a moment and arrive at the respective welding positions in the order of the shift. All bottom welds are done by each team.
The team leader will take the lead, and other staff will cooperate. Masters from the brother team will also observe. If you have any questions, ask me in time!" Zhao Jingfu glanced at the welders in front of him, "Director Lu and Mr. Hu gave many instructions, our welding work is related to
When it comes to the quality of the Blue Whale, we must strive for excellence and not be sloppy in the slightest. If there are quality problems, don't blame me for being rude!"
"Squad leader, don't worry!" One after another voices rose among the welders.
"Preheat, start work!" As the work bell rang, Zhao Jingfu waved his hand and started a new day of work for the welders.
Although Zhao Jingfu issued the order to start work, the workers did not directly pick up the welding guns and start working. Instead, each one took out a pamphlet from his pocket and began to recite it silently.
The booklet is a welding key point written by Zhao Jingfu based on his own experience based on the types, properties and thickness of the steel plates required to be welded by the Blue Whale, as well as the welding process flow of steel plates of various specifications. This is a very important point.
Only by strictly following the welding process can we complete the task with guaranteed quality. Otherwise, quality accidents and even safety accidents may easily occur.
Regarding Zhao Jingfu’s welding experience, not to mention the workers of Fengyang Shipyard, even other shipyards of Fuhai Group also praised Zhao Jingfu’s experience. In Hu Yufeng’s words, the bosses of other shipyards have offered high prices to poach Zhao Jingfu several times, but they were all rejected by him.
He refused directly with words. He couldn't bear to let go of such a good treasure.
"Master Zhao, do you think there is something wrong with the slope here?" A worker waved to Zhao Jingfu.
Grooving is a necessary process for welding thick steel plates and extra-thick steel plates. If the groove is not handled well, it will have a great impact on the welding effect.
Zhao Jingfu quickly came to the steel plate, squinting his sharp eyes and looking along the slope, and couldn't help but frown.
Although he had inspected this batch of steel before, he did not inspect every steel plate carefully. He only checked the specifications and materials. The inspection of the grooves could only be found at the welding site.
"Is it off by about 0.5 millimeters?" Zhao Jingfu didn't even take out the caliper from his backpack. He turned to ask the worker on the side.
The worker immediately gave a thumbs up and said, "Master Zhao is really amazing, the bevel deviation is 0.45 millimeters!"
"What do you think of this deviation?" Zhao Jingfu asked the workers around him, pointing to the steel plate.
"Squad leader, the f690 groove deviation is less than one millimeter, which can be compensated for by welding!" Someone immediately suggested a compensation method.
Zhao Jingfu nodded slightly: "Yes, we can use later welding to compensate for this deviation, but this compensation comes at the expense of our welding quality! Even if we can complete the welding with high quality, we cannot allow this behavior to continue.
Keep developing!”
"Monitor, what do you mean..."
"Mark, go back!" Zhao Jingfu said unceremoniously.
"Isn't this bad?" A worker said in a low voice, "If we are so picky, why won't the pre-processing people jump high? If they give us little shoes to wear, I'm afraid our work will not be easy to do!"
"
"Go back!" Zhao Jingfu said categorically, "If we solve the problem for them this time, what should we do next time? Also help solve the problem? How can we ensure the high quality of the Blue Whale? Only by starting from the source and completing each process step by step
Only by completing it strictly in accordance with the specifications can we build the most powerful Blue Whale!"
Listening to what Zhao Jingfu said, the workers looked at me and I looked at you. Although this was about pre-processing, it was actually meant for them. Once they had any quality problems, Zhao Jingfu would never be vague.
The steel plate with a slight flaw in the groove was immediately returned by Zhao Jingfu.
The workers in the pretreatment workshop went crazy when they saw the returned steel plates. After hearing this, Yuan Feng, the director of the pretreatment workshop, immediately became anxious and immediately went directly from the office to the workshop.
"What happened? I heard that Zhao Jingfu returned the steel plates to you?" Yuan Feng asked angrily.
"Director, look at it, the deviation is less than 0.5 millimeters. It's not a big problem. It's still within the scope of the specification. He, Zhao Jingfu, returned it. Since he became the test supervisor of F690, he can expand
Well, to put it bluntly, this is a slap in your face!"
"Yes, Director, if a welder likes to withdraw our steel plates, he will withdraw our steel plates. If this spreads, the whole shipyard will laugh at our workshop!"
The workers in the pretreatment workshop immediately started talking in Yuan Feng's ears.
Yuan Feng heard what the workers said, and then carefully inspected the steel plate returned by Zhao Jingfu. There was indeed only a deviation of 0.45 millimeters, which was not a big problem.
His fiery temper suddenly rose, and he turned around and went straight to Zhao Jingfu's welding site.
At this time, the welding field was already full of welding flowers, and everyone was welding carefully. After Zhao Jingfu completed the first welding, he handed over the subsequent work to the skilled workers behind him, while he checked the quality and quality one by one in the field.
Are the workers' operating procedures strict?
The thickness of f690 is too large, and the difficulty of welding is beyond imagination. Although his workers have already gained a lot of experience in conducting low-temperature CTOD experiments, when they actually face the huge steel plate, they are still a little unable to do it. Everyone is struggling.
Be very careful, for fear of causing damage accidentally.
Zhao Jingfu was inspecting it. When he looked up, Wei Yuhui came over with people from the inspection department.
