Chapter 59: Practicing Internal Strength

“The welders in our shipyard are all master craftsmen, especially your Uncle Zhao, whose skills are even more outstanding.” Qin Baoshan said proudly.

In his eyes, Qin Tao's suggestion that master welders should practice welding was unnecessary.

“That’s right, Taozi, your Uncle Zhao is a special-level worker, and what he welded was a beautiful crow’s foot.” Aunt Wang said from the side: “You 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 come up with internationally recognized certificates, such as Lloyd's Register, Norwegian DNA, American ABS Classification societies, with these certificates, are capable. Needless to say, we now have a new ZC classification society certification agency in China. 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 been building ships for most of his life, has never heard of these things.

“That’s right, we build the ship ourselves, do we still need certification from others?”

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

Shipbuilding seems to have little technical work. It is just welding a hull. All the equipment on it is purchased from outside, and even the design drawings are provided by relevant units.

 What does a shipyard do? Isn't it just welding all at once?

Yes, this welding is a test of real skills. Ships have to sail on rough seas, and if there is a problem with a weld, it may lead to a disaster. Therefore, welding must have strict requirements.

Each developed country has its own shipbuilding standards. A welder does not just have several levels of technicians. He must have a special shipbuilding-related certificate.

 In the past, domestic shipbuilding was not so troublesome. The shipyard was responsible for the quality. After the ship was built, the user came to receive it and simply inspected it, which was regarded as handover.

 Now, the domestic shipbuilding industry is integrating with the world, and it has also experienced the cruelty of world standards. During the ship building process, the user will entrust a specialized agency to inspect it. If any part is unqualified, it will require rework.

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

 Now, the workers in the shipyard are sitting in the well and watching the sky. They don't know that a large number of first-class welders have emerged in the Huating Shipyard. The level of the craftsmen in the big countries is still far from the welders in the Mingzhou Shipyard!

"Taozi, you want to test your Uncle Zhao, right?" At this moment, the welder Zhao Changshui came over and said, "Anyway, it's not time to weld 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 site and said, "Just weld a pipe on this steel plate."

Zhao Changshui nodded, skillfully picked up a cut three-point pipe, poked it on the scrap steel plate, put the welding ground clamp on it, and then picked up the welding handle.

He didn't even need to wear a protective helmet. He grabbed the three-point tube poked on it with his left hand and the welding handle in his right hand. He poked it once or twice and sparks appeared. Then, he moved his right hand slowly, sparks from the arc splashed, and the welding rod circled the joint. The seam turned in a circle.

His head turned to one side, without even looking, and he worked entirely by feeling. Still holding a cigarette in his mouth, his posture was definitely that of a master chef.

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

“Your Uncle Zhao’s craftsmanship is first-rate.” Qin Baoshan said with emotion from the side: “When we used to weld fishing boats, the most difficult parts to weld were all done by your Uncle Zhao.”

Before he finished speaking, he saw Qin Tao picking up the workpiece in one hand and walking out.

"where you go?"

"Hospital."

 “Why are you going to the hospital?”

 “Take an X-ray.”

Everyone stared at him, not knowing what Qin Tao was going to do.

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

 “Let’s see.”

Zhao Changshui took it out curiously and took a look. Then his expression changed and the cigarette in his mouth fell to the ground.

"what happened?"

“The fish-scale weld that looks beautiful on the surface has three pores, and two places are not burned through.” Qin Tao said: “So, this welded workpiece is unqualified.”

 Simple welding of plates and pipes can test the level of a welder. Even if the surface has beautiful fish scales, problems will occur internally.

 If the welding time is not enough, it may not be burned through. If the welding time is too long, the inside will melt excessively, and air may be mixed in, forming pores.

 On the surface, it still has beautiful fish scale patterns, but internally, it is not perfect.

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

"We haven't seen it before, but we will meet it in the future. We can't wait until customers use this method to inspect it before we know that our welding technology is not up to standard." Qin Tao said: "We must practice diligently from now on to let Our technology has reached a higher level, and no matter what kind of ship we build, we can satisfy our 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-ray is not very strong, and a stronger radioactive source should be used for metal flaw detection. But when I checked the information, I found that the device used in shipbuilding is an X-ray flaw detector, so I assume it can meet the requirements. As for the hospital's I really don’t know if it works or not, so please just comment lightly.)

Everyone was silent. Zhao Changshui held the X-ray plate and slowly clasped it with both hands.

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

“Can the quality of the workpieces produced by welders withstand the inspection of X-ray flaw detectors?” Zhao Changshui asked.

“That’s for sure. They gritted their teeth and worked hard to practice their internal skills when taking on foreign shipbuilding tasks.” Qin Tao said.

"If they can do it, then we can do it too." Zhao Changshui clenched his fists: "I will also pass the exam for those 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 further progress.”
