Monster Factory

Overnight, the metal melting center has forged one-fifth of the marine alloy steel modules.

These modular steels do not require any further processing, or water-fired panels like ordinary shipbuilding.

Twenty giant laborers have begun to carry out hull welding of super giant wheels on the load pile foundation. They used two magnetically assisted lifting devices to piece together a piece of modular alloy steel and weld it with the most advanced welding techniques that humans have not yet mastered.

Not to mention anything else, just because this welding technology is exposed, it can provoke the American industrial sector to be completely crazy.

Welding is a very important technical issue in industrial processing.

The most common type of arc welding is the welding technique in which a transformer is placed and the electrode is used there. This kind of welding method has quite a hint of eating and eating all over the sky.

However, in a slightly graded factory, this welding technique can only be used to weld some scaffolding and scraping materials. If you want to solder your product, you should use semi-automatic submerged arc welding or automatic gas shielded welding technology.

When Ye Qing first recruited a lot of hard work, he used the welds welded by electric arc welding to make Ye Qing amazed.

The inside describes the welds beautifully, and there is a saying called fish scales. That is, the welds are layered like fish scales and are very neat. This fish scale can only be welded by hand if it is the top welder. At the same time, evenly scattered weld lines also represent the quality of this weld is very guaranteed.

The internal cracks of the solder joints are small and the strength is consistent.

If the master is coming, he can solder whatever he wants and even paint with the weld.

The emergence of automatic welding technology has solved the jagged flaws in workers' welding techniques. The smooth automatic wire feeding mechanism and the self-propelled guide rail ensure the uniform weld height between the metal materials. It is also the only technology used to weld precision construction.

but……

They can't weld extra thick parts.

Welding wire can only be welded on metal surfaces, which is a commonsense problem. But for very large machines, the thickness of the metal that usually needs to be welded is more than ten centimeters. If it is only welded on the upper and lower sides, there is a gap in the middle, and the strength is much lower than that of the unwelded. In the event of a collision or strenuous exercise, a metal break will occur.

This is especially fatal in the giant wheels that need to fight against the waves.

Therefore, in order to be able to weld qualified ultra-thick parts, the engineers racked their brains and tried everything.

For example, when welding ultra-thick parts, first cut the two materials to be welded, cut out the **** surface, and then stack and weld them one by one. Before the more advanced welding technology, Master, who can master the welding technology of ultra-thick parts, is a national treasure.

The thickness of the weld can be about the same, which represents the rarity of the master.

With the development of welding technology, and mechanical motorization technology. Welding super-thick pieces, there have also been a scene of group dance, the various non-mainstream technologies that everyone can master are endless, until after the call **** welding technology developed, unified rivers and lakes.

Electroslag welding can weld ultra-thick parts such as tank armor. Its principle is to reserve a gap of about 30 mm in advance when welding. When welding, the welding wire slowly melts and accumulates in the gap, filling the reserved gap little by little.

but……

Electroslag welding can not weld the super thick hull of this super freighter. Because the defects of electroslag welding are also expected to be obvious, the heat generated during welding is extremely high and the welding time is long. When welding, the two weldments must be firmly clamped with the clamp to ensure that no thermal deformation occurs.

At the same time, a certain angle is required to ensure that the welding **** is accumulated in the reserved seam. This angle is best for vertical. If it is inclined, the maximum can not exceed 30 degrees, otherwise the welding **** will overflow.

瞧瞧 Now in the Longxitan factory, this ultra-high-speed freighter is being welded. Its important part of the armor thickness, actually exceeded two meters. Most of the rest is between 50 cm and 1 m. How do you weld this?

The weight of tens of thousands of tons of super giant wheels, how to fix it, how to rotate, to ensure that the weld is always vertical?

The Newport News Shipyard is here, and we must also cry in the boat platform.

The only non-mainstream solution is to cut the angle of inclination less than 30 degrees at the weld before welding, and use the surfacing technique to semi-manually weld. But the problem is coming. Let's not say that it is going to be welded for a few years. How can this high-strength armor material quickly cut out the slope?

After welding, how to ensure the overall strength of the weld, no cracks, bubbles, **** inclusions?

Ask this question, first understand how the fearless ships with armor thicknesses of 40 to 70 centimeters were made during World War II.

Simple, people do not need to weld at all, and there is no welding technology. The thin armor is layered with rivets.

This is also the reason why a warship is built, which lasts for several years and can only be manufactured by a specific worker.

The strength of multi-layer splicing is naturally much worse than that of forging and re-welding shell armor in terms of strength and resistance to metal fatigue. It is also more time consuming. After World War II, this technology was eliminated by big countries.

The ultra-thick hull welding technology that has made the world headaches is easy to be solved by Longxitan Shipyard, oh no, it was the Longxitan factory.

Two car-sized 3D electron beam metal-melting printing equipment, one by one, relies on magnetic attraction on both sides of the ultra-thick armor. They rely on the electron beam, and in the internal vacuum bombardment chamber, the special alloy metal powder prepared by the metal expert is instantaneously bombarded into a high-speed fluid between the liquid and the gaseous state.

These fluids are sprayed into the gaps of the module armor held by the magnetic robot through a special nozzle.

The gap is only five millimeters wide, and the ejected helium fluid collides with each other like the particles in the particle accelerator, and rapidly cools and solidifies under the action of the auxiliary cooling nozzle, and is attached in the middle of the gap. Two electron beam printing devices, which perform synchronous fast reciprocating motion, fill the armor gap quickly like a printer.

Armor is an armor that is doped with cemented carbide, but these printed materials are super hard alloy powders that metal experts have carefully matched. After printing, this "weld" is not only under the metal observation equipment, but also presents a perfect metal crystal arrangement without any darkness and bubbles.

And the "weld" strength is higher than the armor of this super freighter.

This is the real top industrial technology, and Ye Qing dares to use a civilian super-huge to counter the strength of the warship. Of course, its cost is also surprisingly high.

To put it bluntly, the United States will not be able to master this technology even after five or more years.

............

Another day passed, in the Longxitan factory, this super giant ship was first seen.

Starting from the bow, the most pure alloy steel breather shell has been built by one-fifth. On the back of the alloy casing, there is a strip of criss-crossing alloy keel.

A certain proportion of nickel-titanium memory alloy is added to these alloy keels. The industrial term of metal fatigue is never there before it.

7:30 in the morning.

Ye Qing told the high-level that the research and development [electromagnetic engine] in the factory has entered a critical moment. He will be stationed at the factory to stare at the project these two days.

The company's affairs are well arranged and arranged. Ye Qing deliberately made a new hairstyle.

Originally, Ye Qing was a short black hair. This time, the shovel on both sides was short, and the above was very layered. It became the most popular "airplane head" of the young people at the moment, and it was dyed a little, only under the light. Can you see the linen green.

A Prada fashion men's wear, with sunglasses that can be discolored, Ye Qing is now a handsome and young son.

At 10 o'clock in the morning, Ye Qing came to Zhongyun Airport with a low-profile metal expert with a bodyguard. Instead of taking the private channel to take the exclusive plane, you will take the VIP channel and fly to the capital in the first class, then transfer to Japan.

The three-dimensional camera is the exclusive item of Ye Qing and can only be used by himself, so Ye Qing is going to visit the aircraft carrier.
