Chapter 59
"The welders in our shipyard are all masters, especially your Uncle Zhao, whose skills are even more outstanding." Qin Baoshan said proudly.

In his opinion, Qin Tao said that it is unnecessary for master welders to practice welding.

"That's right, Taozi, your Uncle Zhao is a special-level worker, and what you welded is a beautiful crow's feet." Aunt Wang said from the side: "I also participated in the welding skills competition in East China and won the second prize."

Qin Tao shook his head: "Those are all in the past tense. Now, if you want to say that your skills are superb, you have to show international certification certificates. The British Lloyd's Register, the Norwegian DNA Classification Society, the American ABS ship Classification society, with these certificates, it is called ability, needless to say, we now have a new ZC classification society certification body in our country, without these certifications, the technical level will not be recognized."

"What did you say?" Qin Baoshan was a little surprised: "What are these?"

Qin Baoshan, who has built ships for most of his life, has never heard of these things.

"That's right, we build the ship ourselves, and we still need certification from others?"

Qin Tao sighed, knowing that there is still a long way to go to develop the shipyard.

Shipbuilding does not seem to have any technical work. It is just welding the hull. All the equipment on it is outsourced, and even the design drawings are given by the relevant units.

What is the shipyard doing?Isn't it just welding all at once?

That's right, this welding is a test of real skills. As long as the ship sails on rough seas, a problem with a weld may lead to a disaster. Therefore, welding must be strictly required.

Every developed country has its own shipbuilding standards. An electric welder does not need to have a few levels of technicians, but must have a special certificate related to shipbuilding.

In the past, domestic shipbuilding was not so troublesome, and the quality of the shipyard was the responsibility of the shipyard itself. After the ship was built, the user came to receive it, check it briefly, and it was considered a handover.

Now, the domestic shipbuilding industry is in line with the world, and has also experienced the cruelty of world standards.In the process of ship construction, the user will entrust a special organization to inspect, and any place that is unqualified will require rework.

With the expansion of Mingzhou Shipyard, as domestic ship users gradually broaden their horizons, Mingzhou Shipyard will definitely experience this kind of thing. Forging iron requires their own hard work, and they must practice their internal skills hard.

Now, the workers in the shipyard are watching the sky from a well. They don't know that a large number of first-class welders have emerged in the Huating Shipyard. The level of craftsmen in a big country is still far behind the welders in Mingzhou Shipyard!
"Taozi, you want to test your Uncle Zhao, right?" At this moment, electric welder Zhao Changshui came over and said, "Anyway, it's not time for welding yet, so Uncle Zhao will show you his skills." , you said, what do you want to weld?"

Qin Tao looked at the scraps left at the scene and said, "Weld a pipe on this steel plate."

Zhao Changshui nodded, skillfully picked up a three-point pipe that had been cut off, poked it on the scrap steel plate, put the welding ground wire clip on it, and picked up the welding handle.

He didn't even need to wear a protective helmet. He held the three-point pipe poked on it with his left hand and the welding handle with his right hand. He poked it once or twice, and sparks came out. The seam turned a circle.

He turned his head to one side, without looking, and worked entirely by feel.Still smoking a cigarette in his mouth, this posture is definitely the style of a master.

After the sparks of the arc disappear, beautiful fish scale patterns appear on the weld seam, which is well-proportioned and beautiful, and it is the best at first glance.

"Your Uncle Zhao's craftsmanship is top-notch." Qin Baoshan said with emotion from the side: "When we used to weld fishing boats, the most difficult places to weld were all done by your Uncle Zhao."

Before he finished speaking, Qin Tao picked up the workpiece with one hand and walked out.

"where are you going?"

"Hospital."

"Why are you going to the hospital?"

"Take an X-ray."

Everyone stared wide-eyed, not knowing what Qin Tao was going to do.

Half an hour later, Qin Tao came back with an extra X-ray plate in his hand.

"Look."

Zhao Changshui took it out curiously, glanced at it, and then his expression changed, and the cigarette in his mouth fell to the ground.

"what happened?"

"This fish-scale weld that looks beautiful on the surface has three pores, and two of them are not completely burned." Qin Tao said: "So, this welded workpiece is unqualified."

The simple welding of plates and pipes can test the level of a welder. Even if the surface is beautiful with fish scales, there will be problems when it comes to the inside.

If the welding time is not enough, it may not be able to burn through. If the welding time is long, the inside will melt too much, and air may be mixed in to form pores.

On the surface, there are still beautiful fish scale patterns, but the inside is not perfect.

"Taozi, isn't this too picky? We've never seen an X-ray inspection of a weld." Qin Baoshan said to Qin Tao.

"I haven't seen it before, but I will meet it in the future. We can't wait until the customer uses this method to test that we know that our own welding technology is not up to standard." Qin Tao said: "We must start from now, practice hard, let Our technology has improved to a higher level, no matter what kind of ship we build, we can satisfy customers. By the way, we also need to buy an X-ray flaw detector to check whether the parts we weld are qualified at any time."

(The penetrating ability of X-rays is not very strong, and a stronger radioactive source should be used for metal flaw detection. But when I checked the data, I found that the device used for shipbuilding is an X-ray flaw detector, so let’s assume that it can meet the requirements. As for the hospital’s It’s okay, I really don’t know, everyone lightly sprays.)
Everyone was silent, Zhao Changshui held the X-ray base plate, and slowly clenched his hands.

"Also, I will find a way to hire an experienced master welder from Huating Shipyard, let him guide everyone's welder skills, and strive to become a first-class welder as soon as possible."

"Can the quality of the workpieces of those welders withstand the inspection of the X-ray flaw detector?" Zhao Changshui asked.

"That's for sure. They also gritted their teeth and worked hard to practice their internal skills when undertaking foreign shipbuilding tasks." Qin Tao said.

"If they can do it, then we can do it too." Zhao Changshui clenched his fists: "I will pass the test for the certificates you mentioned!"

"Yes, Uncle Zhao, come on!" Qin Tao said: "If our Mingzhou Shipyard wants to develop and progress, we need you old craftsmen to make great strides."
