Electric welding is a metal processing technology that accompanies the development of the electric power industry. In the original history, the electric welding technology that can really be used in production was invented at the end of the nineteenth century.Although the traversers of Haihan have mastered this technology long ago, they have not been able to apply this technology to the current industrial production because the welding materials required for electric welding cannot be produced by themselves.Yu Feng's breakthrough in this area is of great significance to Haihan's industrialization process. Come join in the fun.
Yu Feng's machinery factory has military production tasks all year round, so he has dealt with the Ministry of National Defense a lot, and he is familiar with Yan Chujie. Of course, he understands why the other party is interested in this technology—if the electric welding process can be widely used When applied to industrial production, ordnance technology will also be greatly improved. For example, the ironclad ship that the Navy has always dreamed of may be able to come out much earlier.
"You two come to my office and sit down for a while. We have to wait for the workmanship test." Yu Feng raised his wrist to look at the time on his watch, and said to the two senior executive committee officials: "It won't be long, wait another half Just an hour."
Yan Chujie asked puzzledly: "Old Yu, you're just testing your craft, don't you have to wait for an auspicious time to do it?"
Yu Feng explained with a smile: "I don't have that much trouble. Do I have to wait for the power transmission from the hydropower station? I applied for an hour at noon, so I have to wait until twelve o'clock to use the electricity."
The hydropower station built on the upper reaches of the Tiandu River has relatively limited power generation capacity, and part of the power needs to ensure the power consumption of Shengli Fort.Especially for the big data center set up in Fort Victory, it is necessary to give priority to ensuring a stable power supply for 24 hours.However, the various production units in Tiandu Industrial Zone can only share the remaining electric energy equally, and in order to ensure efficiency, they have to arrange staggered peak use.
Although Yu Feng's machinery factory has also pulled the transmission lines, in fact, the machinery used in daily production has basically been replaced with steam-powered equipment, so it is not among the fixed transmission objects of the Tiandu Hydropower Station. Can only apply for temporary electricity.
As the minister of the Ministry of Industry, the power production and transmission are naturally within the scope of his work, so he coughed dryly and said, "If the welding process passes the verification, the power consumption arrangement on your side can be adjusted according to production needs in the future. "
Yu Feng said: "Minister Bai, there will only be more and more projects that need electricity in the future. After all, it is not a solution to dig the other wall to make up for the other wall. We still have to find ways to increase the power generation capacity!"
Bai Kesi nodded and said: "The flow in the upper reaches of the Tiandu River is limited, and it is difficult to increase the power generation scale. However, we have already surveyed several places in the upper reaches of the Linchun River and the Sanya River. If everything goes well, it will be completed next month. Two new hydropower stations have been started simultaneously, and after completion, the current power supply problem in the Tiandu Industrial Zone can be basically solved.”
It is not only the natural environment and engineering capabilities that restrict Haihan's development of the power system, but in the final analysis it is still a reserve of professional talents.From a long-term point of view, whether it is the most basic electrician or the engineer who can manage power transmission and transformation equipment, it is far from enough to rely solely on the technical personnel in the traverser group, so the training of professional talents has always restricted Haihan's development. Some achievements have been made in this regard.Now, more than ten years have passed, and Haihan has finally accumulated a certain amount of talents in this area, and can finally put the expansion of power generation scale on the agenda.
Yu Feng invited Bai Kesi and Yan Chujie to sit in his office. Although the machinery factory was full of oil and soot everywhere, Yu Feng's reception room was cleaned by a special person, and it was always cleaned very clean. He let the two The apprentice brought hot tea and planned to discuss some scientific research matters with Bai Kesi and Yan Chujie.
"In addition to electric welding, I have been working on diesel engines recently. If I can make this thing, it will be of great benefit to us whether it is used as a generator or power equipment." After Yu Feng sat down, he Straight to the point, he told the two about another of his research.
Bex said: "But our oil refining process is not ideal at present. The quality of the mass-produced fuel is limited, and the damage to the engine will be relatively large. Maybe you need to talk to someone from the chemical department to learn about the current crude oil refining process. The specific situation of technology and fuel, see if they can prepare some high-quality fuel for you separately."
Regarding the development of fuel engines, Haihan's industrial sector has actually been going on for several years.Design principles, materials, structures, and manufacturing techniques are all ready-made. There are many plans in the large database, and the official has been conducting research and development in this area.However, limited by the oil refining process, the progress in this field is still very limited. Even if Yu Feng is capable of producing a fuel engine, Beks believes that the actual application effect should be affected by the fuel currently available. The research and development work organized by the Ministry of Industry is not much different.
Of course, Bai Kesi will not stop Yu Feng from doing this kind of research, he is willing to spend his own money to engage in scientific research activities, just like sponsoring refugee orphans to study, it is a long-term investment, and there will be more or less certain returns in the future.If Yu Feng can really achieve some good results, it will be a good thing for Hai Han.
The purpose of Yu Feng's initiative to mention this matter is to report to Beks. He only needs the approval from the Ministry of Industry. As for the specific development plan, he has his own plans and will not conflict with the official organization's development project.
Everyone chatted for a while, and it was the scheduled time. Yu Feng's two apprentices had already prepared all the relevant equipment, but the specific operation still had to wait for Yu Feng to do it himself.After all, electric welding is still an incomprehensible metal processing technology for people in this era, and it takes a long time of training before it can be practically operated.
"Master, a call has been sent." Huang Zhichang knocked on the door and entered the office, and reported the situation outside to Yu Feng.
"Let's go, get the business done first, and we'll go have lunch!" Seeing that everything was ready, Yu Feng got up and invited him.Bai Kesi and Yan Chujie did not delay, and immediately followed him out of the office.
The area used for the electric welding test is specially used for various tests, and it is separated from the outside production area workshop, so there are no workers around at this time.Of course, even if someone wanted to join in the fun, the accompanying guards of Bai Kesi and Yan Chujie would stop them all outside.
Yu Feng had already prepared several strong light masks and asked his two apprentices to send them to Bai Kesi and Yan Chujie.After several people present had put on their masks, Yu Feng also put on the masks, turned on the power of the electric welding machine, picked up the welding torch and welding rod and started to operate.
The welding rods tested by Yu Feng today have two specifications: 2mm and 2.5mm, which are used to weld several square steel plates with a thickness of 5mm and several steel bars with a diameter of 10mm that have been cut in advance, and then verify the bonding firmness and strength of the welded materials. tenacity.
Yu Feng hadn't performed welding operation for a long time, and at this time there were two senior officials of the Executive Committee watching beside him. In order to avoid mistakes, he consciously slowed down the operation speed, so as to achieve the desired result in one go. welding effect.
However, he welded two square containers with the cut small square steel plate, which took about four to 10 minutes, and then welded two steel bars. Yin Dezhi reminded him that the temperature of the welding machine was too high and he had to stop. Let the machine cool down slightly.Yu Feng stopped to look at the time, and it was about to be the limited time for turning on the switch, so he decided to stop there, turn off the electric welding machine, and ask the apprentice to take out several welded samples for inspection one by one.
After the welded square container was naturally cooled, liquid was poured into it for airtightness testing. However, there was a small leak in one of the containers. The three of them checked carefully with a magnifying glass, and finally confirmed that the leak was actually It was Yu Feng's workmanship, not the quality of the welding machine or welding rod, so the airtightness test still ended in a pass.
Then the toughness test is carried out on the welded steel bars. First, place the position of the welded joint of one of the steel bars on a hard material and hit it with a hammer to observe whether there are cracks at the welded joint.Huang Zhichang and Yin Dezhi took turns hammering for a long time, until the round steel bar was beaten into square strips before finally cracks appeared, and it took nearly a hundred more blows to completely break the welded joint. At this time, the fracture was basically hammered into an iron sheet .
Next, the bending test with an iron bender on the welded part of another steel bar is also ideal. After several bending operations, there are only tiny cracks in the welded part, which is quite good performance under the current conditions.
"Fortunately, I didn't disgrace my life!" Yu Feng finally breathed a sigh of relief after seeing the test results.After such a long preparation work, we are waiting for today's acceptance process. If there are any mistakes, all the previous work may be in vain. This naturally makes him very nervous.Fortunately, both the process and the result are not bad, and the welding effect is better than I expected. I think Bex can't find anything wrong with it.
"Currently we can only use these two specifications of welding rods? Can we weld larger pieces?" Beks was not as easy to deal with as he thought, and immediately raised a question that Yu Feng couldn't avoid.
Yu Feng had no choice but to answer honestly: "The specifications of the welding rods used are limited by the power of the welding machine. If we want to weld larger parts, then we have to build a welding machine with a higher power. Standard welding rods will do.”
"Then where are the current manufacturing difficulties?" Bex continued to ask.
Yu Feng responded: "The difficulty in making welding rods at the beginning was mainly in the raw materials. We spent a lot of time looking for the origin of these materials. If the raw materials for welding rods are supplied in sufficient quantities in the future, this stuff can be manufactured in Changhua Hetiandu, and the production capacity will increase. The cost will naturally be low. The manufacturing principle of the electric welding machine is not difficult, but it requires a lot of copper wires, and our supply of copper wires is very unstable. Like I built this electric welding machine, in order to wait for the corresponding specifications of copper Line, waiting for almost three months. So the manufacturing period of the electric welding machine may be longer, and the corresponding cost will also rise, I think you can understand."
"For the supply of copper wires and other materials, you can make a separate list for me later, so that I can coordinate these things for you." Beks was very straightforward, and immediately said that he would solve these problems raised by Yu Feng.
"Then I'll thank Minister Bai first!" Yu Feng said happily.
"Don't thank me in a hurry. If you want to order four electric welding machines of this specification and a batch of welding rods, how long will it take you to produce them? How about the cost?" Bex asked.
As soon as Yu Feng heard it, he knew that Beks was going to place an order with his factory on behalf of the Ministry of Industry, and he admired his decisiveness at the moment.But Yu Feng didn't reply in a hurry, he was very clear about the production capacity of his factory, this time to produce four welding machines, he still had to calculate the construction period and cost.Immediately, he said to Bai Kesi: "It's been busy all morning. I don't know if you two are hungry or not. Anyway, I am very hungry. How about we change places and talk while eating?"
"Alright. Let's talk about it in another place." Actually, Bai Kesi was not in a hurry to use the electric welding machine. Of course, he also wanted to use this to test Yu Feng and see if the other party had any hidden skills.
Yu Feng ordered the two apprentices to clean up the place, while he accompanied Yan Chujie and Bai Kesi to leave the machinery factory.Although there was a cafeteria in the factory, since he wanted to talk about business and he needed to ask Bex for some help later, Yu Feng felt that it was not good to wrong these two pampered people, so he decided to go back to the city to have this meal.
The three of them returned to the urban area by carriage, and Yu Feng found a restaurant he was familiar with and opened a secluded private room.The three of them had their own business in the afternoon, so they didn't let the store serve the wine.
"There's an important coordination meeting in the afternoon. People from all departments will be present, and Lao Yan and I will also be present, so we won't drink at noon." Bai Kesi was afraid that Yu Feng would be overwhelmed, so he took the initiative to explain the reason.
Yu Feng inquired curiously: "What is this for coordination?"
"About Shandong." Since Yu Feng took the initiative to ask about it, Bai Kesi didn't intend to hide it from him. Anyway, he could read the relevant news in the nearest newspaper.
Yu Feng suddenly said: "Is it going to transport refugees to the country again?"
Bai Kesi nodded and said: "Fushan County has now accommodated tens of thousands of refugees, and more refugees will flood into the area in the future, so we must quickly deploy transportation capacity and supplies, and try to send these refugees to the country for resettlement."
Yan Chujie said: "This work involves too many regions and departments, so people from all departments have to be called together for a meeting to assign tasks. If the operation goes smoothly, the population should increase by tens of thousands this year."
