Monster Factory Chapter 769: : departure to visit aircraft carrier

Overnight, metal smelting center has forged a fifth of marine alloy steel modules.

These modular steels do not require any processing or ordinary shipbuilding.

20, named Juli, has started to weld the hull of the Exceed Grade giant ship on the pile foundation. They used two magnetic assists to lift device, put together blocks of modular alloy steel, and welded them with the most advanced welding technology that humans have not yet mastered.

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

Welding is a very important technical topic in the industrial processing.

The most common type is arc welding, which is a welding technique in which a transformer is held and a welding rod is used to point and point there. This kind of welding method is quite fresh, and it feels like eating everywhere.

However, in the slightly higher grade Factory, 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 first recruited Juli toil, the welds he welded with arc welding made Ye Qing shocked.

An expert describes 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 fish scale pattern can be welded by hand-made only by the top welder Master. At the same time, the uniformly scattered welding lines also guarantee the quality of the represented weld.

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

If Master Craftsman 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 uneven welding technology of worker. The stable automatic wire feeding mechanism and self-propelled guide rail ensure that the weld height between metal materials is consistent. At the same time, this is the only technology used to weld precision construction.

But...

They can't weld very thick parts.

The welding wire can only be welded on the surface of metal, which is a matter of common sense. But for super large machines, the thickness of metal that usually needs to be welded is more than ten 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 vigorous exercise, the metal will break.

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

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

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

The thickness that can be welded is approximately larger, the greater the rare level of represented, the master.

With the development of welding technology and mechanical motorization technology. Welding ultra-thick parts, there has also been a chaotic dance situation. Various non-mainstream technologies that everyone can master are emerging in an endless stream, until the development of incoming call **** welding technology, dominating the world.

Electroslag welding can weld super thick parts, such as tank armor. Its principle is that when welding, 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 can't weld the super thick hull of the Exceed Grade cargo ship in front of you. Because the defects of electroslag welding are also obvious, extremely heat is generated during welding 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 **** accumulates in the reserved seam. The best angle is vertical. If it is inclined, the maximum cannot exceed 30 degrees, otherwise the welding **** will overflow.

Look at the ultra-high speed cargo ship that is being welded in Dragon Creek Beach Factory. The armor thickness of its important parts unexpectedly exceeds two meters. Most of the rest is between 50 cm and one meter. How to weld this?

The Exceed Grade giant wheel weighs tens of thousands of tons, how to fix it and how to rotate it to ensure that the weld is always vertical?

Newport News Dockyard is here, and we have to cry together in the slipway.

The only non-mainstream solution is to cut the inclination angle less than 30 at the welding place before welding, and use surfacing technology to half hand-made to weld. But here comes the question. Let’s not talk about the plan to complete the welding in a few years. How can this super-strong armor material cut out the **** quickly?

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

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

Simple, people don’t need welding at all, and they don’t have that welding technology. They directly splice thin armor one layer one layer with rivets.

This is also the reason why it takes several years to build a Warship, and only a specific worker can be manufactured.

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

The super-thick hull welding technology that has given the world a headache, was easily overcome by Dragon Creek Beach dockyard, oh no, Dragon Creek Beach Factory.

Two car-sized 3D electron beam metal fusion printing device, one up and one down, relying on magnetic force to adsorb on both sides of the super thick armor. They rely on electron beams to instantly bombard the special alloy powdered metal made from Metal Specialist into a high-speed fluid between liquid and gas in the bombardment chamber of the internal vacuum.

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

The gap is only five millimeters wide. 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 device are doing synchronous and fast reciprocating movement, like a printer, quickly filling the armor gap.

The armor is doped with hard alloy, but the printed materials are Super-hard alloy powder carefully matched by Metal Specialist. After printing, this "welded seam" not only shows a perfect metal crystalloid arrangement under the observation of metal device, without any dark injuries or bubbles.

And the strength of the "welded seam" is higher than the armor of this Exceed Grade cargo ship.

This is the real top industrial technology, and Ye Qing dared to use a civil Exceed Grade giant ship to counter the military vessel's confidence. Of course, its cost is also surprisingly high.

To put it hard, USA will not be able to master this technology even in five years or ten years.

…………

Another day passed, inside Dragon Creek Beach Factory, this Exceed Grade giant ship, first saw a terrible look.

From the bow of the ship, the purest alloy-steel shell has been constructed by one-fifth. On the back of the alloy shell, there are stripes criss-crossed, like the Golden Dragon bones of a dragon.

A certain percentage of Nickel-Titanium Memory Alloy has been added to these Golden Dragon bones~IndoMTL.com~. The industrial term metal fatigue will never exist in front of it.

7:30 in the morning.

Ye Qing announced to the senior management that the research and development [Electromagnetic Engine] in Factory has entered a critical moment, and he will be stationed at Factory for the two days to stare at this project.

Company affairs are well arranged. After the arrangement, Ye Qing made a new hairstyle specially.

Previously, Ye Qing had short black hair. this time cut the sideburns short on both sides, and the trim on the top was very layered. It became the most fashionable and most popular "Plane Head" among young people. The flax green can only be seen from below.

A fashionable Prada men's wear, with sunglasses that can change colors at will, Ye Qing is now a handsome and young boy.

In 10:00 in the morning, Ye Qing brought a bodyguard Metal Specialist to Zhongyun Airport in a low-key manner. Instead of taking the private passage to take the exclusive plane, you take the VIP passage. Take the first class flight to the capital and then transfer to Japan(ese).

3-Dimensional Camera is Ye Qing’s exclusive item and can only be used by herself, so Ye Qing wants to visit aircraft carrier.
