Li Fusheng said: "Brother Shen, you are in such a hurry, you will go back tomorrow, I will take you around and we will be Rongshun!"
” Shen Huan smiled: "You know, I'm busy, next time!"
” Seeing that he couldn't keep it, Li Fusheng had to give up this idea.
However, he didn't expect that halfway through lunch in the restaurant, Shen Huan's mobile phone rang.
Shen Huan took out his mobile phone and saw that it was Mr.
Fu calling, and he quickly picked it up.
"Mr.
Fu, hello!"
Shen Huan said.
Fu Jianjian's voice was a little anxious: "Comrade Shen Huan, are you still in Rongshun now?"
” Shen Huan said: "I'm still eating, and I'm going to go back to Zhonghai in the afternoon!"
Are you in a hurry?
” Fu Jianshe said: "It's okay, don't come back yet, there's something over there, I'll tell you in detail, that's ......"
After listening to Fu Jianjian's description, Shen Huan understood what was wrong, it turned out that there was a batch of welding rods purchased from Rongshun Dapingyang Welding Electrode Company recently had quality problems, and now the company is also very anxious, because this batch of welding rods is a special welding rod for special welding parts of the passenger ro-ro ship.
If this problem is not solved as soon as possible, it will seriously delay the construction progress of the Ro-Ro passenger ship, and if the ship cannot be delivered on time, it will face a huge penalty fine.
When Shen Huan heard this, he also realized the seriousness of this problem, which was indeed a thorny problem.
Where is the reason, now Jiangnan Changxing Shipbuilding Group and Sichuan Dapingyang Welding Electrode Company have not figured it out, so this time Fu Jianshe will personally take several welding engineers and senior technicians from Jiangnan Research Institute to Rongshun to go deep into Dapingyang Welding Electrode Company, and their technicians to find the cause and solve the problem.
Shen Huan happened to be in Rongshun, so Fu Jianshe asked Shen Huan not to return to Zhonghai first, let him stay, and go to Dapingyang Welding Electrode Company with him, Fu Jianshe has great hopes for Shen Huan, he knows that there are many thorny problems, as soon as he arrives at Shen Huan, he doesn't know how to solve them easily, although Shen Huan has not been responsible for welding affairs, but he still has a little expectation that Shen Huan can help the company solve this problem.
Shen Huan hung up the phone, he knew that this matter was very urgent, and Mr.
Fu and they would rush to Rongshun tonight.
Li Fusheng asked, "Brother Shen, what's wrong?"
Is something wrong?
” Shen Huan nodded and said: "Yes, it is also a coincidence to say, there is a problem with a batch of special welding rods imported by our Jiangnan Changxing Shipbuilding Group, and this batch of welding rods is produced by your Dapingyang Welding Electrode Company in Rongshun City."
So now I don't go back, tonight the company Fu will come overnight with technicians, if this problem is not solved, there will be a lot of trouble!
” Li Fusheng said in surprise: "What?
This, this is also too coincidental!
I, a Rongshun person, really don't know that our welding electrode company here also produces welding rods for shipyards!
” Sichuan Dapingyang Welding Electrode Co., Ltd., the full name is Sichuan Dapingyang Welding Materials Co., Ltd., it is China's first welding material manufacturer, founded in 1949, can be said to be quite early, in 1969 it was called China Welding Electrode Factory, in 1996 it was restructured into Sichuan Dapingyang Group Co., Ltd., to 99 years Sichuan Dapingyang Group Co., Ltd. and several enterprises initiated the establishment of Sichuan Dapingyang Welding Materials Co., Ltd., 01 year listed on the China Overseas Stock Exchange.
The main products of Dapingyang have been recognized by the China Classification Society, Lloyd's Register of Shipping, the United States Survey Ship Association, the French Classification Society, the Decidental Soede Classification Society, the Nawei Classification Society, and other world-class classification societies.
Shen Huan is no stranger to this welding material company, because nearly one-third of the welding materials used by Jiangnan Changxing Shipbuilding Group are purchased from this company.
If you think about it carefully, isn't the risk of new welding processes and new welding materials greater than ordinary?
With the rapid development of the shipbuilding industry, welding technology and welding materials are also constantly improving, in the past, this kind of welding materials have to be imported from abroad, but domestic manufacturers through efforts or the introduction of technology, but also gradually able to produce more welding materials.
Welding is too important for shipbuilding, because in the construction of a ship's hull, the welding cost accounts for one-third to one-half of the hull construction cost, of which the welding cost, including welding materials, equipment, man-hours and energy consumption, etc., the cost of welding materials is the highest.
China has already become a big producer of welding materials, the output of welding rods accounts for more than 60% of the world's output, among which there are many foreign welding materials companies in the country to build factories, the country's welding materials manufacturers are about 300, but one of the oldest manufacturers with the longest product quality is Dapingyang welding materials company.
The most widely used in the shipbuilding industry is the gas shielded solid welding wire, since the nineties, this material has been the largest use, accounting for half of the amount, this time the problem is also this new type of gas shielded welding solid wire.
You must know that in 2003, the consumption of shipbuilding welding consumables in China's shipbuilding industry has exceeded 60,000 tons, and the more powerful marine welding consumables manufacturers include Sichuan Dapingyang, Tianjin Shuangying, Wuhan Tiemiao, etc., and the sole proprietorship or joint venture has rice Lincoln, European Issa, foot basin Kobelco, rod Koryo and other manufacturers.
It can be said that Sichuan Dapingyang has been cooperating with Jiangnan Changxing Shipbuilding Group for many years, and it is the first time that such a big problem has occurred, and Shen Huan is also very puzzled, what is the problem?
Only after Mr.
Fu and them arrived, they would have a detailed understanding of the situation and go to Dapingyang Company together.
Shen Huan also knows very well that the ro-ro passenger ship built this time has a lot of new designs and new processes, and the problem is also the welding of the bow thruster part, because this part is very special, so it began to be built almost at the same time as the main body of the hull.
The two bow side thrust adopts the design of the cylinder, which is made of B-grade plate and a certain type of stainless steel composite plate, and the chemical composition is very complex, so it is also very important in the design of the welding process and the selection of welding materials, because while ensuring the quality of welding, it is also necessary to avoid the influence of the stainless steel composite layer by low carbon steel.
How do you know that there is no problem in the welding process test, but in the actual construction of the welding process, there is a problem, and the welding quality inspection is not good!
After an emergency meeting of experts from the Jiangnan Research Institute such as Fu Jianjian, the experts agreed that there was a problem with the welding materials.
