The old things I repaired have become fine

Chapter 230 The flowers and ornaments are scattered on the ground but no one wants to pick them up... Who would dare to ask for the monster's craftsmanship?
Shen Le tortured himself to death, over and over again, until he finally honed his welding proficiency.

One-step forming, uniform weld shape, smooth transition between the weld and the adjacent silver sheet, and clean removal of welding slag;

Visual inspection shows that there are no surface pores and no unwelded areas;
The weld is parallel to the silver sheet and does not penetrate into the silver sheet...

Then, he stared at the 3D reconstruction of the Phoenix Coronet, the places where the solder had been removed deep inside the crown, connecting the flower ornaments and the Phoenix Coronet, and the places where the copper wires were about to break due to oxidation, and began to stare blankly:
How to weld?
How can I go through these densely packed pearl flowers, green leaves and green clouds and weld together the parts that need to be strengthened?
The key point is, how to make the flame of the spray gun reach a sufficient temperature at the welding site to ignite the solder without damaging the nearby kingfisher feathers and pearls?
——The melting point of solder is around 600 to 700 degrees, and the flow temperature - that is, the temperature at which it will flow like water and penetrate into the weld after melting - reaches 700 to 800 degrees.

With such a high temperature, there is no need to spray it directly. Even if you spray the edges, the kingfisher's feathers will be burned and the pearls will be roasted and fried into powder!

Shen Le held the spray gun and measured it again and again, trying to find a place in the dense web-like phoenix crown where he could insert the spray gun.

If you stretch it from the top, the flowers and jade are too dense. If you want to spread them apart, you need to push them to the side, which will cause the connection part below to deform. It will be troublesome to reshape it later.

The flames from the spray gun can directly burn the pearl flowers and green feathers from below. No matter how tilted or slanted it is, it can't be avoided...

Shen Le tried for a long time and poked it with a thin wooden stick for a long time, but still couldn't get it right.

I had no choice but to send the photo of the phoenix crown and the 3D reconstruction made by CT to my senior who was doing jewelry restoration:

"Senior, please tell me, in this case, how should we weld it so as not to affect the pearls and the green feathers?"

There was silence on WeChat for half an hour. Shen Le waited until lunch time, and finally got a reply, but it was not a paper or a video, but a screenshot of an online shopping search:

Small handheld laser welding machines, various brands, various models, prices are around 15,000 yuan...

Obviously, what the elder brother meant was:

Why don't you use laser welding?
Shen Le: “…”

Fine……

So, after all the twists and turns, I finally have to buy a laser welding machine, right?

To be honest, it’s not that expensive, but it occupies a very large area!

If he needed one, he would buy one. If he needed one, he would buy one. Before long, his studio would be full.

At that time, would he build another cement house in an inconspicuous place in the corner of the old house, or simply buy the house next door?
Shen Le sighed, but there was nothing he could do. He had to ask his senior to send him the model of the laser welding machine used in the laboratory and placed an order for one according to the model.

Before the welding machine arrived, he began to work hard to clean the phoenix crown.

To remove dirt and scale, for the oxidized parts, you cannot scrape them off with a scalpel or even a brush, but apply a thin layer of gel:

After leaving it for a while and cleaning the gel, those underneath the phoenix crown will immediately flash with bright light.

But... no matter whether you use a stick or a brush to paint, those sticks and brushes will inevitably reach into the dense jungle that looks like a Pansi Cave.

By then, the tiara will be crooked or slanted, and it will definitely have to be re-made. Just thinking about the workload makes me feel miserable...

But Shen Le had his trick. He sat in front of the Phoenix Crown, picked up a little bit of gel with a stick, and held it flat in front of his eyes;

As the spiritual power surged, the gel naturally flew up, passed through the Pansi Cave, and landed on a thin thread. It wrapped around, stretched, and applied a thin layer.

"Well done." Shen Le gave himself a thumbs up and operated on the computer next to him to record the exact time when he applied the filament;
Then, pick up a little more gel, apply it with concentration, and record again...

After recording everything, I waited for a while and used my mental power to remove the gel. As expected, the body of the Phoenix Corona was shining brightly, as clear as new. "Okay... the oxidation has been removed, and now we need to do some corrosion protection. It will last for a while... not hundreds of years, but at least a few decades..."

He prepared a bottle of BTA solution and sprayed it evenly… Spraying is not a good idea as it will damage other materials behind it, but it is still very simple to apply it evenly using mental power.

After applying, wait for the solution to dry, then apply another layer of insect wax, and you’re done!
This job is simple to say but complicated to do. It is very demanding to coat every strand of silk and every stitch.

If Shen Le hadn't treated it as a coloring game, painting a stroke and changing a little color on the three-dimensional pattern of the computer phoenix crown, he wouldn't have been able to bear it until he finished it all:
"Ah... Next is gilding... Am I supposed to do this at home? This is too much of a test..."

Not only does it test people, but it is also highly toxic.

Gilding is to dissolve gold with mercury to form amalgam, and then apply it to the objects that need to be gilded. Then use fire to evaporate the mercury, leaving only gold...

Just imagine how toxic this volatile mercury vapor is. Without professional equipment, it is impossible to handle this stuff!

Shen Le called around and asked around, but couldn't find any studio that could do gilding craftsmanship and was willing to lend their equipment.

Professor Lin’s son, Mr. Chen Guohua, who runs an antique studio, also answered as a matter of course:
"Who still uses gilding now? It wastes gold and is highly toxic! If you are not an inheritor of an intangible cultural heritage and you insist on inheriting this craft, wouldn't it be better to use electroplating?"

Shen Le: “…”

In the end, it was Lao You who helped Shen Le solve the problem. Among his group of monster friends, there was actually one who liked to play with these things:

Shen Le brought the finished flower ornaments to the other side and watched him open his mouth wide and swallow the silver ornaments in one gulp.

Then, with a gold pendant in his left hand, he chewed and chewed, swallowing it down;
With a bottle of mercury in his right hand, he tilted his neck back and began to hum…

Shen Le: “…”

Take it easy!

Don’t cause any human death, no, don’t cause any monster death!

He was terrified and stared at the boss's face, his finger already on the phone, ready to dial at any time.

It won't work to call 120 with an extra 0. The doctor probably can't handle the situation of such a fierce man. But, maybe calling Dr. Qin can help?

"Uh……"

The monster's chubby face broke into a smile, and he opened his big mouth and burped loudly. An unpleasant smell rushed out, and he raised his hand to catch it, and two golden flower ornaments fell into his palm:

"Take it!"
