"Two functions that even developed countries in Europe and America don't have?" Qin Gangsheng asked suspiciously.

"That's right!" Wen Dawei nodded: "One is the preheating function of the workpiece..."

Speaking of this, Wen Dawei turned the ZJ-280 underwater cover-type semi-automatic welding machine over, pointed to the cover that is in contact with the pipeline and said: "We have added a preheating system to weld the pipeline at a water depth of 60 meters. The workpiece is preheated and then welded."

After hearing this, Qin Gangsheng's eyes were not as simple as widening, but almost protruding.

It should be known that the workpiece preheating function is only available in high-pressure underwater dry welding machines or atmospheric pressure underwater dry welding machines.

And these two kinds of dry welding equipment are powerful products specially used for deep-sea welding. They are all like small submarines. They are not accessible to ordinary companies or countries. They are only available in superpowers such as the United States and the Soviet Union. "Toy".

Taking advantage of the relationship between the United States and Europe, although Europe has acquired some technologies, the key core technologies are in the hands of the United States, and every move depends on the face of the Americans.

It is also because of this that this type of offshore construction is completely monopolized by several large offshore engineering contractors in Europe and the United States.

The reason for this is the same sentence. The environment under the ocean is different from that on land. As the water depth increases, the temperature will decrease. However, many pipelines are made of high-quality alloy metals, which require carbon dioxide gas protection on land. Special welding processes such as welding or plasma welding, let alone underwater.

Due to the reduction of temperature, the mechanical properties of these special alloy metal pipe fittings are reduced, and the weldability is seriously reduced. Therefore, preheating the workpiece is the fundamental method to solve such problems.

But the problem is that the current mainstream underwater welding equipment is either deep-water welding equipment like small submarines in Europe and the United States, or Japan’s PT-90 Kawasaki Heavy Industries semi-automatic underwater welding machine, which is a small welding equipment similar to wet welding. .

There is no underwater equipment that can both heat workpieces and weld.

Is it beyond the imagination of developed countries?
Of course not, the main reason is that they don't think it's necessary. Anyway, they have monopolized the entire submarine project. The existing equipment is already crushed. At least it will not be a problem to maintain it for one to 20 years.

That being the case, why spend so much effort on development and research?
How happy it is to make money first.

Otherwise, competition will promote technological progress. Qin Gangsheng can imagine that once the ZJ-280 underwater cover-type semi-automatic welding machine of Zhujiang Factory is rolled out in the Southeast Asian market, with this underwater heating function, It can basically sweep the welding market of underwater pipelines in Southeast Asia.

Because of this, Qin Gangsheng's heart, which was silent because of his wife's early illness, suddenly felt like a dead wood was in spring. Staring at the ZJ-280 underwater cover-type semi-automatic welding machine in front of him, it was like seeing a heart-beating goddess, and he wanted to hug her directly. kissed the couple, and then hurried into the bridal chamber.

Fortunately, Qin Gangsheng knew that it was not the time to be excited yet, so he suppressed his excitement: "What about the other function?"

Wen Dawei pointed to a mechanism on the torch head that was similar to the torch head and said, "This is it, the welding slag cleaner."

"My God, you even have this!" Qin Gangsheng was immediately surprised.

How can the welding process not produce welding slag? The most direct way on land is to tap the surface of the workpiece with a hammer to shake off the welding slag attached to the weld.

After all, the welding slag will undergo certain chemical reactions under the action of the residual temperature of the weld, destroying the structure of the weld.

But this action is a bit difficult in the sea, especially in the deep sea under tens of meters. Leaving aside the problem of pressure and bulky diving equipment, as far as the metal materials to be welded are concerned, some pipes have particularly strong adhesion to welding slag. It's not something that can be solved with a hammer.

Special cleaning equipment is required to deal with it on land, let alone on the seabed.

The problem is that this type of professional welding slag cleaning device is only available in deep-sea high-pressure dry welding machines or atmospheric pressure dry welding machines. Because it is a small submarine, the platform has a large space, so it can naturally install more supporting equipment.

For the rest, one counts as one, and none at all.

But at this moment, the ZJ-280 underwater cover-type semi-automatic welding machine has broken the industry rules. The parts heating and welding slag cleaner are integrated into the semi-automatic welding machine, so that its performance can completely match that of some professional welding machines in Europe and America. The deep-sea welding machines in the hands of offshore engineering contractors compete!
"Of course, our ZJ-280 underwater cover-type semi-automatic welding machine is not perfect, because it adopts workpiece heating technology, and plasma welding slag cleaning process, plus its own welding torch, automatic wire feeding and other functions, consumes a lot of power. The quantity is a bit large, so..."

"What does it matter if the power consumption is high? As long as it can solve the problem!" After introducing the two additional functions, Wen Dawei talked about the shortcomings of the ZJ-280 underwater cover-type semi-automatic welding machine, but he didn't say anything yet. The end was interrupted by Qin Gangsheng's indifferent wave of his hand: "No matter how energy-consuming your ZJ-280 underwater cover-type semi-automatic welding machine is, how high is the energy consumption of those deep-sea welding machines in Europe and America?

I once saw it in Malaysia. One operation would consume two-thirds of the energy consumption of a 5000-ton auxiliary ship. The Malaysian government gritted its teeth to complete the project, and never dared to start work again. Really can't afford it! "

Wen Dawei smiled even brighter when he heard the words: "Our ZJ-280 underwater cover-type semi-automatic welding machine is not, at least slightly higher than the energy consumption of similar products in Japan, but please don't worry, Boss Qin, as long as you give us some In time, we will definitely come up with replacement products with lower energy consumption, of course, the premise is that you have confidence in our Zhujiang factory!"

"Mr. Wen, we Chinese often say that people don't speak dark words. To tell you the truth, I saw your underwater wet welding equipment before and planned to cooperate with you, but I didn't think too deeply, because I don't know I know how good you are in this area and how long you can last."

He said and pointed to the ZJ-280 underwater cover-type semi-automatic welding machine beside him: "But looking at this baby today, I know that you have worked hard in this area, and you also have great perseverance and perseverance to make this machine work. Things are going on, if that’s the case, why can’t I have full confidence in you? After all, this thing is a king bomb with the ability to sweep the underwater welding market!"

"If that's the case, then I won't be polite to Boss Qin..." Wen Dawei was also very arrogant, but Qin Gangsheng was even more arrogant: "Why are you being polite to me, we are almost a family, so don't talk about two families!"

"When do you expect to pay the franchise fee of 5000 million Hong Kong dollars a year?" Wen Dawei laughed so hard that Qin Gang's heroic demeanor came to an abrupt end...
