Zhao Jingfu holds a welding gun and slowly fills the gap between the two steel plates under the action of temperature and chemical reaction, and finally merges them into one, forming a whole.
The title of "King of Welding" is certainly not given in vain. Although the work clothes on his body were soaked with sweat, the welding gun in his hand was not affected at all. It still moved slowly, and the straight welding seam appeared in everyone's eyes.
"The master's craftsmanship is really superb!" Meng Yiwu, who is only 19 years old, sincerely admired that at his age, Zhao Jingfu is already able to undertake difficult welding tasks on his own, but currently he can only start with ordinary steel plates to practice. As for this
On such occasions, I can only observe and observe.
It's not that Zhao Jingfu doesn't believe in his ability, but just keeping the welding gun stable for such a long period of time is enough to scare these young people away. You must know that in order to be able to stabilize the welding gun, Zhao Jingfu used it just like practicing in the army.
The scrap steel plate is tied to the welding gun with a rope to practice strength with one hand.
There are very few young people today who are so willing to endure hardships. Even people like Meng Yiwu who are willing to do welding are much rarer.
Fortunately, the booming development of robotic welding technology has prevented places such as Fengyang Shipyard, which has a large number of welding tasks, from being short of manpower. However, some difficult welding tasks still require manual operations, which highlights the importance of senior welders.
After the first steel plate is welded, it still needs to be kept warm for several hours to stabilize the stability of the solder. No one knows what the welding result will be until it returns to normal temperature.
Zhao Jingfu ignored the completed steel plate. He knew that no matter how good his skills were, he would not be able to find the exact solder and process flow at once, so he didn't need to pay attention to it. He immediately selected several other specifications with different specifications.
Experiment again with different solder.
The test site was filled with smoke. Even though several high-power fans were whirring, it was impossible to eliminate the smoke that came out at any time. Wei Yuhui and several others were choked and coughed.
"After all, you are in the office!" Zhao Jingfu shook his head slightly and pointed to the car outside. "You guys go back to the car and have a rest. After the temperature of the steel plate has dropped, we can start testing again!"
Seeing what Zhao Jingfu said, Wei Yuhui wanted to argue a few words, but looking at the situation inside, it seemed that staying inside would not be of much use. She reluctantly exited the factory and sat in the car looking at these big and thick men.
They are constantly busy.
Wei Yuhui sat there and watched for a while, and decided that she could not sit like this all the time, and she also needed to help with something. She immediately took out her laptop and began to draw tables on the low-temperature CTOD experimental data. In the future, she would use these tables to
With the data, you can see at a glance how far it is from the final standard.
Soon, the first steel plate had cooled down and was ready for pressure testing.
At this time, Zhao Jingfu was already a little tired. He handed the welding gun in his hand to the workers behind him and continued the welding operation. Then he pulled over a worn-out chair and sat on it directly, watching his subordinates continue to work.
The smart Meng Yiwu next to him quickly handed over the big cup filled with tea leaves.
"Master, how do you feel? When can I get started?" Meng Yiwu asked in a low voice.
Zhao Jingfu glanced at him, then pointed at the workers who were working and said, "Don't always follow me. You should also watch when the old workers are working. Every old worker in our team has a
There is a unique skill, as long as you learn it down-to-earth, you will be able to master it soon. Don’t be too ambitious and always think about how to do the big job!”
At this time, there was a burst of laughter from behind the two people. Zhao Jingfu looked back and saw that it was Wei Yuhui who came to check the condition of the steel plate and heard the conversation between the two.
"Why are you laughing?" Zhao Jingfu asked with some confusion.
Wei Yuhui pointed at Meng Yiwu and then at Zhao Jingfu, "He is a few years younger than you. Why do you think you are dozens of years older than him based on the tone of his voice?"
"Are you calling me old?" Zhao Jingfu laughed, "I am warning him not to always think about getting something for nothing!"
"I know you are good and can teach others a lesson!" Wei Yuhui pointed at the ultrasonic detector in front of her and asked, "So, Squad Leader Zhao, are your steel plates welded now? Can I test it?"
Zhao Jingfu immediately checked the time and temperature, and found that they had reached the standard.
"That's it!"
Wei Yuhui came to the steel plate with instruments of various sizes such as ultrasonic detectors. She first skillfully checked the appearance of the weld to see if there were cracks, underheating, etc.
Although Zhao Jingfu is very confident in his skills and has welded ultra-thick steel plates before, he is not sure what will happen to f690 as the most technologically advanced offshore steel in the country based on past welding.
Especially what happened at Hong'an Steel made him fearful, worried that something might happen to the steel plates that he had worked so hard to weld.
Wei Yuhui carefully checked the appearance of the steel plate weld. As a work of a welding king, there was nothing picky about it. Both in terms of flatness and neatness, it was very up to standard.
The ultrasonic inspection found no problems and everything looked perfect.
Zhao Jingfu looked at the detected data and felt more and more uneasy. Although there were no accidents in this welding, the result was so perfect. He, Zhao Jingfu, was really lucky. He found the welding materials and process in one fell swoop.
No one can trust it!
After everything was tested, Wei Yuhui asked the workers to lift the steel plate to the pressure strength testing instrument in preparation for strength testing.
Sure enough, a problem occurred. When the strength was only increased to half, small spider-like cracks appeared in the weld. It was known without detection that the welding had completely failed!
With a crisp cracking sound, the two F690 steel plates broke directly from the interface, and the welding traces were clearly displayed in front of everyone.
"The strength of the welding material is insufficient and the pressure test failed!" Wei Yuhui sighed and handed the final pressure test data to Zhao Jingfu.
Zhao Jingfu took a look and didn't say anything. He knew that this was something he had to go through, but he didn't expect that the carefully selected welding materials could not be reused. They could only reach half the strength of f690. It seemed that the welding materials needed to be used.
