Monster Factory - 779

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

These modular steels do not need to be processed anymore, or are bent panels like ordinary shipbuilding.

Twenty Juli hard workers have already begun welding the super giant ship’s hull on the pile foundation. With the help of two magnetic assisted lifting devices, they pieced together blocks of modular alloy steel, and used the most advanced welding technology that humans have not yet mastered for welding.

Not to mention anything else, just the exposure of this welding technology can drive the U.S. industrial sector completely crazy.

Welding is a very important technical topic in industrial processing.

The most common is arc welding, which is a welding technique that holds a transformer and uses a welding rod to point and point there. Everyone has seen this welding method.

However, in slightly higher-grade factories, this welding technique can only be used to weld some scaffolding and scraps. If you want to weld products, semi-automatic submerged arc welding or automatic gas shielded welding technology must be used the most.

When Ye Qing recruited Juli for the first time, the welds he welded with arc welding shocked Ye Qing.

Experts describe the weld seam as beautiful, and there is a saying called fish scale pattern. That is, the welds are layered on top of each other like fish scales, very neat. This kind of fish scale pattern can only be welded manually by top welders. At the same time, the evenly scattered welding pattern also represents 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 of exquisiteness comes, he can weld any lines he wants, and even paint with welding lines.

The emergence of automatic welding technology has solved the embarrassment of workers with uneven welding skills. The stable automatic wire feeding mechanism and self-propelled guide rail ensure that the weld height between the metal materials is consistent. At the same time, this is the only technology used to weld precision construction.

but……

They cannot weld very thick parts.

The welding wire can only be welded on the metal surface, which is a matter of common sense. But for super large machines, the thickness of the metal that needs to be welded is usually more than five centimeters. If only the upper and lower sides are welded, there is a gap in the middle, and the strength is much lower than the unwelded place. In the event of a collision or violent exercise, the metal will break.

This is especially deadly on a giant ship that needs to fight against the waves.

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

For example, when welding ultra-thick parts, first cut out the slope of two pieces of material to be welded, and then pile up and weld them layer by layer. Before the more advanced welding technology, the masters who could master the welding technology of ultra-thick parts were all national treasures.

The larger the thickness that can be welded, the more it represents the rarity of this master.

With the development of welding technology and mechanical motorization technology. Welding ultra-thick parts, there has also been a chaotic dance of demons. Various non-mainstream technologies that everyone can master have emerged in an endless stream. Until later, the electroslag accumulation welding technology was developed to dominate the rivers and lakes.

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

but……

Electroslag welding cannot weld the super-thick hull of this super freighter. Because the defects of electroslag welding are also quite obvious, the heat generated during welding is extremely large, and the welding time is long. When welding, the two weldments must be firmly clamped with a fixture to ensure that no thermal deformation occurs.

When welding at the same time, a specific angle is required to ensure that the welding slag accumulates in the reserved seam. The best angle for this angle is vertical. If it is inclined, the maximum angle cannot exceed 30 degrees, otherwise the solder will overflow.

Look at the ultra-high-speed freighter being welded in the Longxitan factory. The armor thickness of its important parts unexpectedly exceeds two meters. Most of the remaining thickened armor parts are between fifty centimeters and one meter, and the normal parts that are not thickened are also 20 centimeters thick.

How to weld this?

How to fix the super giant wheel with a weight of tens of thousands of tons and how to rotate it to ensure that the welding seam is always vertical?

The Newport News shipyard is here, and we must cry blindly in the shipyard.

The only non-mainstream solution is to cut out an inclination of less than 30 degrees at the welding place before welding, and use surfacing technology to do semi-manual welding little by little. But here comes the question. Let’s not talk about the plan to complete the welding in a few years. How can this super-strength armor material cut out the slope quickly?

After welding, how to ensure the overall strength of the weld without cracks, bubbles, and slag inclusions?

To ask this question, we must first understand how dreadnoughts with special thickened parts and armor thicknesses of 40 to 70 cm were manufactured during World War I and World War II.

It’s simple. People don’t need welding at all, and they don’t have that welding technology. They just use rivets to splice thin armor layer by layer.

This is also the reason why it takes several years to build a battleship, and only certain workers can build it.

The strength of multi-layer splicing is naturally better than that of forging, forming, and then welding shell armor. In terms of strength and resistance to metal fatigue, the difference is very, very much. It also takes more time. After World War II, this technology was eliminated by the naval powers.

Now, the super-thick hull welding technology that has given the world a headache is easily overcome by the Longxitan Shipyard, oh no, the Longxitan Factory.

Two car-sized 3D electron beam metal fusion printing devices are up and down, relying on magnetic force to attach to both sides of the ultra-thick armor. They rely on electron beams to instantly bombard special alloy metal powder prepared by metal experts into a high-speed fluid between liquid and gas in the bombardment chamber of the internal vacuum.

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

The gap is only five millimeters wide, and the jetted bright fluid collides with each other like particles in a particle accelerator, and is quickly cooled and solidified under the action of the auxiliary cooling nozzle, and adheres to the gap. The two electron beam printing devices are doing synchronous and fast reciprocating motions, like a printer, quickly filling up the armor gaps.

Armor is armor doped with cemented carbide, but these printed materials are super cemented carbide powder carefully matched by metal experts. After printing, this “welded seam” not only shows a perfect arrangement of metal crystals under the metal observation equipment, without any dark injuries or bubbles.

And the strength of the “welded seam” is higher than the armor of this super cargo ship.

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

To put it awkwardly, the United States will not be able to master this technology even in five or ten years.

…………

Another day passed, and this super giant ship in the Longxitan factory first saw a terrifying sight.

Taking the bow as the starting point, the purest alloy-steel aura shell has been constructed by one-fifth. On the back of the alloy shell, there are strips of alloy ribs crisscrossing each other, like dragons.

In these alloy reinforcement ribs, a certain proportion of nickel-titanium memory alloy is added. The industrial term metal fatigue will never exist in front of it.

It’s half past seven in the morning.

Ye Qing declared to the senior management that the research and development of the [electromagnetic engine] in the factory has entered a critical moment, and he will be stationed in the factory for the two days to stare at this project.

The company’s affairs were well arranged. After the arrangement, Ye Qing deliberately made a new hairstyle.

Originally, Ye Qing had short black hair. This time, he cut the sideburns short on both sides, and the trim on the top is very layered. It has become the most fashionable and most popular “airplane head” by young people. The flax green that can only be seen underneath.

Wearing a fashionable Prada menswear outfit with sunglasses that can change colors at will, Ye Qing is now a handsome and young boy.

At ten o’clock in the morning, Ye Qing brought a metal expert who looked like a bodyguard to the Zhongyun Airport in a low-key manner. Instead of taking the private passage to take the Peregrine Falcon, you take the VIP passage. Take the ordinary first-class cabin and fly to the capital first, and then transfer to RB.

The 3D camera is Ye Qing’s exclusive item and can only be used by himself, so Ye Qing wants to visit the aircraft carrier.
