As soon as Xu Xinhua left, Han Sanjiang said: "Lao Mu, Lao Mu, our store is not a place to do small buying and selling, we are running a large enterprise, as long as the advantages of some things far outweigh the disadvantages, we lose small profits and make big profits, why not do it? You, everything is good, it's just a little petty! Let's look at her experiment tomorrow and then make a decision!"

Jiang Yuanqiao also echoed: "Yes, yes, seeing is believing, if we don't see the results, we don't want to make a statement!"

Mu Chunfeng looked at the two of them, smiled contemptuously, and replied: "Two colluded guys, you know that if you send your property out, sooner or later, you will regret it, although our store is rich, we can't give away the land and build a liquefied gas station for her, right? By the way, Lao Han, do you have a crush on that girl Xiao Xu? Why did you suddenly give her so generous to build a liquefied gas station? There must be something wrong with this?"

Han Sanjiang glanced at Mu Chunfeng and said, "Old Mu, how beautiful you were at the beginning, you chased and beat me hard, did I ever like you, how could you say such a thing? Yes, his wife hasn't been back for two years, which inevitably makes Mu Chunfeng suspicious! But his old Han is not that kind of person, he always has Wang Ling'er in his heart, and no woman can replace her.

Seeing Han Sanjiang leave unhappily, Jiang Yuanqiao pointed at Mu Chunfeng and said softly: "Old Han is angry, don't say this in the future, he only has Wang Ling'er in his heart, and he can't pretend to be another woman, do you understand?"

When Mu Chunfeng heard this, he was stunned, sat on the sofa in the conference room, and responded for a long time: "I know, I know, I won't say this in the future!"

The next day, Xu Xinhua brought several sets of welding torches matched with liquefied gas, including small, medium, and large, with different lengths and different uses.

I saw these welding guns, the appearance is almost the same, the two pipes are connected together, one up and down, there is a black adjusting screw behind the pipe below, it seems to control the size of the air flow, no different from the valve, the golden alloy pipe above, and the gold alloy pipe below, the middle of the pipe is connected by two erected small pipes, which is used for gas reflux, and the front end of the pipe above sticks out of a sharp nozzle, which is the muzzle of the fire.

Xu Xinhua pointed to the welding torch and said: "Look at this gun, the long one is used to cut steel, the medium one is used to cut thin metal with iron sheet, and the smallest one is used to weld gold, silver, copper and other welding rods." As she spoke, she plugged the liquefied gas pipe into the welding torch, twisted the black valve, and lit the fire, which looked soft and fluffy, without any force, and she adjusted the knob, and the fire was "puff, puff, puff······ The ground rang out, and dark purple fireworks were sprayed forward, and the concentrated fire was sprayed at one spot, burning the air so that it "crackled".

The companion called by Xu Xinhua had already placed a copper pipe and a copper joint on the ground, she handed Xu Xinhua a silver electrode, opened the special solder paste of the silver electrode, and put it in front of her.

Xu Xinhua put on a pair of sunglasses, and after bringing them on, he said: "Secretary Han, the smallest welding torch is used to weld gold, silver and copper, the one I hold in my hand is a silver welding rod, and the small iron box in front of it is filled with silver solder paste and flux." Saying that, she used the head of the silver electrode to pick a little flux, and then used a musket to spray fire on the copper joint, and after a while, the copper joint was red, and immediately sprayed fire on the copper pipe, and in the blink of an eye, both were red, and she immediately put the silver electrode to the joint, and after a while, the silver electrode was matched at the link of the pipe, and the interface was patched, and she skillfully turned over the pipe and welded the connection around. After a while, the welding was successful, and the welding time was completed in just over one minute and fifty seconds, and it was done in one go.

After cooling, Han Sanjiang took a closer look at the joint, it looked smooth and rounded, and he couldn't see the gap in the connection at all! At present, they weld the air conditioning joint at the entrance of the store, although it is also welded with silver electrode, but it is welded by kerosene burning, although the welding gun is the same, but the kerosene combustion has no force, the heat is not enough, and there will always be a big pimple when welding, which is really ugly, and I am a little worried that this scar will come off! It took a few minutes in the welding time, and I always felt a little unsteady, and then I changed to gasoline, although the temperature was higher, and the time was a little faster, the scar was still there, and it was a little unsatisfactory.

Han Sanjiang picked it up and handed it to Mu Chunfeng and Jiang Yuanqiao to see, Mu Chunfeng couldn't see anything famous, because she was not an expert in making hardware, Jiang Yuanqiao looked at it, his eyes widened, and said: "This liquefied gas is really awesome, the things that are welded out, there is not even a pimple, it is really a good thing to integrate?" It is so enviable, this is simply a myth in the welding industry!"

As soon as Mu Chunfeng heard Jiang Yuanqiao's words, she immediately understood, she remembered, there was always a pimple in these welding places, protruding from the old and high, and it was a little unnatural to look at, and the things welded out of this liquefied gas were integrated and natural, and you couldn't tell that it was welded up at all. This is the same interface as running water, and you can't see the unevenness, and there will be any gaps and abrupt bumps in the docking place. It's completely a whole, except for some different colors in the welding places, there are no flaws to be seen.

Xu Xinhua smiled and asked, "Are you satisfied, are you satisfied?" There are even more satisfactory ones in the back, you can watch!" As she spoke, she changed to a medium-sized gun, turned on the switch, lit the fire, and adjusted it to the maximum firepower.

The companion spread the tin sheet on the ground, drew a flower with chalk on the tin sheet, and left with a smile.

Xu Xinhua came to the iron side and put on sunglasses, followed the arc of the painting flower, aimed the flame down, and after a while, an iron flower was cut out along the splashing spark.

Han Sanjiang, Jiang Yuanqiao, and Mu Chunfeng suddenly widened their eyes, looked at the iron flowers cut out of the ground, and said in disbelief: "This is simply incredible!

Xu Xinhua smiled and said, "Mayor Mu, do you like it, if you like it, I'll cut a few more flowers for you!"

Mu Chunfeng replied: "Didn't you say that the spear is even more remarkable? Then take out the spear and let us see where it is great!"

"Okay, good, witness the miracle right away! You have a good look!" Xu Xinhua said as he changed his spear, lit the fire, adjusted the flame, and "puff, puff, puff, ······puff, The sound of fireworks became even stronger. Sounds a little panicked.

At this time, Xu Xinhua's men brought over a thick steel plate, three inches thick, and threw it on the ground with a "bang", making a dull sound.

Xu Xinhua grinned, put on sunglasses, came to this thick steel plate, adjusted the nozzle to the maximum flame, divided it into two in the middle of the steel plate, and slowly cut it down, only to see that the place cut by the fireworks kept spraying sparks, and after a while, the steel plate was burned red, and the cutting place continued to splash sparks, just like a flow beam, desperately spraying out towards its arc, and after a while, a hole appeared in the steel plate, which was divided, and in less than twenty minutes, the steel plate was cut in half。

Now Han Sanjiang and they were completely dumbfounded, what the fuck, they used a large saw table, it took two days to saw it in half, and how much soap and water had to be used in these two days, it was solved in twenty minutes! This, in addition to making them dumbfounded, it also felt a little unreal! It was as real as a dream? But it appeared in front of their eyes, such a good thing, where to find it.

Han Sanjiang immediately made a decision to cooperate with Xu Xinhua, and next to a hill, he built a liquefied gas station for them for free, and the name of the liquefied gas station was "Xinhua Liquefied Gas Station".

Later, liquefied gas was used in a large number of welding technology, and the liquefied gas burned at the entrance of the store every year was enough for Xu Xinhua to make a net profit of 100 million.
