Chapter 59 Working hard on internal skills
"The welders in our shipyard are all masters, especially your Uncle Zhao, whose skills are even more outstanding." Qin Baoshan said proudly.
In his eyes, there was no need for Qin Tao to ask the welders to practice welding.
"That's right, Taozi, your Uncle Zhao is a special worker, and the one welded out is a beautiful crow's feet." Aunt Wang said from the side: "I have also participated in the welding skills competition in East China and won the second prize."
Qin Tao shook his head: "Those are all past times. Now, if you want to say that you have excellent skills, you have to come up with international certification certificates, including the British Lowe's Classification Society, the Norwegian DNA Classification Society, and the American ABS Classification Society. With these certificates, you can be a skill. Needless to say, we now have a new ZC Classification Society certification agency in China. If there are no such 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.
"Yes, we build our own ships, and we still need other people's certification?"
Qin Tao sighed, knowing that there is still a long way to go to promote the shipyard.
When building a ship, there seems to be no technical job, it is just welding a hull. All the equipment on it is purchased from outside, and even the design drawings are given by relevant units.
What are the shipyards doing? Isn’t it just welding?
Yes, this welding tests true skills. As long as the ship sails on the turbulent sea, a problem with a weld may lead to a disaster. Therefore, welding must be strictly required.
Each developed country has its own shipbuilding standards. A welder does not need to have a level of technical level, but must have a special shipbuilding-related certificate.
In the past, domestic shipbuilding was not so troublesome, and the quality was the responsibility of the shipyard itself. After the construction was completed, the user would receive it and check it briefly, and it would be handed over.
Now, the domestic shipbuilding industry is in line with the world and has also experienced the cruelty of world standards. During the construction of ships, users will entrust special institutions to inspect. Any place that fails, they will be required to 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. The ironworking needs to be strong themselves, and they must practice their internal skills hard.
Now, the workers in the shipyard are watching the sky from the well. They don’t know that a large number of first-class welders have emerged from Huating Shipyard. The level of craftsmen in the great country is still far from that of the welders in the Mingzhou Shipyard!
"Taozi, I want to take the exam for your Uncle Zhao, right?" At this moment, the welder Zhao Changshui came over and said, "Anyway, it's not time for welding yet, Uncle Zhao will show you his skills. 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 cut three-point tube, poked it on the scrap of the steel plate, put it on the welding ground clamp, and then picked up the welding handle.
He didn't even have to wear a protective cap. He grabbed the three-point tube that poked on it with his left hand, held the welding handle with his right hand, poked it or two, sparks appeared, and then, his right hand slowly moved, sparks splashed in the arc, and the welding rod turned around the joint.
His head turned aside, without looking at his eyes, just working just by feeling. He was still holding a cigarette in his mouth. This posture was definitely the style of a master.
After the sparks of the arc disappeared, beautiful fish scale patterns appeared on the welds, which were well-proportioned and beautiful, and they were the best at first glance.
"Your Uncle Zhao's craftsmanship is first-class." Qin Baoshan said with emotion: "When we used to weld fishing boats, the most difficult places to weld were all done by your Uncle Zhao."
Before he finished speaking, he saw Qin Tao pick up the workpiece in one hand and walk out.
"where you go?"
"Hospital."
"What are you doing in the hospital?"
"X-ray."
Everyone stared at each other, not knowing what Qin Tao was going to do.
Half an hour later, Qin Tao came back and had an X-ray base plate in his hand.
"Look."
Zhao Changshui took it out curiously, took a look, and then his face changed, and the cigarette in his mouth fell to the ground.
"What's going on?"
"This fish scale weld with beautiful surface has three air holes and two of them are not burned through." Qin Tao said: "So, the welded workpiece is unqualified."
Simple welding of plates and pipes can test the level of a welder. Even if the surface is full of beautiful fish scale patterns, problems will arise when it comes to the inside.
If the welding time is not enough, it may not burn thoroughly. If the welding time is long and the inside is melted too much, air may be mixed into it and air may form.
On the surface, there are still beautiful fish scale patterns, but the inside is imperfect.
"Taozi, this is too nitpicking, right? We have never seen it before using X-ray to test the welds." Qin Baoshan said to Qin Tao.
"We haven't seen it before, and we will meet it later. We cannot wait until the customer uses this method to know that our own welding technology is not up to standard." Qin Tao said: "We must start from now on, practice diligently to make our technology a step further. No matter what 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 welded are qualified at any time."
(X-ray penetration ability is not very strong, metal flaw detection should use a stronger radioactive source. However, when checking the information, I found that the ship-building device is an X-ray flaw detector, so I assume it can meet the requirements. As for whether the hospital can work, I really don’t know, so everyone will spray it lightly.)
Everyone was speechless. Zhao Changshui held the X-ray base plate and slowly clasped his hands.
"Also, I will find a way to hire an experienced welder master from Huating Shipyard to come over and ask him to guide everyone's welder skills and strive to become a top-notch welder as soon as possible."
"Can the quality of the workpieces under those welders stand the inspection of X-ray flaw detectors?" Zhao Changshui asked.
"That's for sure. They were also gritting their teeth and practicing their internal skills while undertaking the task of building foreign ships." Qin Tao said.
"If they can do it, then we can do it too." Zhao Changshui clenched his fists: "I will get the exams you mentioned!"
"Yes, Uncle Zhao, come on!" Qin Tao said: "If our Mingzhou Shipyard wants to develop and make progress, you old craftsmen need to go further."
