Yang Yuanzhao is a power engineer, I don't know much about electric welding, but I have been in contact with it when I repair the car, but I brought it from the market, there is an electric welding machine, which does not have any electronic components, or the most basic electric welding machine and welding rod, under the replication of the all-in-one machine, has spread throughout Baotou, electric welding for the improvement of steel structure and other aspects, so that some researchers can see the light, especially the Baotou Research Institute under the guidance of Yang Yuanzhao, continue to more in-depth electric welding methods, a variety of fresh electric welding methods, One after another.

Now, there are seven or eight categories in the northwest, dozens of different welding methods, but unfortunately the application of electric welding to shipbuilding, but it is the first time, even Yang Yuanzhao, but also can only coordinate between shipbuilding engineers and welders, after coming to Jiangnan Shipyard, after solving the adjustment of machinery and personnel, under his single-handed promotion, the first all-electric welding steamship was officially launched.

The total tonnage of the steamship will not exceed 250 tons, the use of a relatively traditional structure, all the real welding has been carried out in the real room, the strength and the effect of electric welding can be guaranteed, after repeated real hair, more suitable for use in the shipbuilding industry, is gas welding, argon arc welding and seamless welding, a small number of submerged arc welding, these were sent to Yang Yuanzhao by telegram.

It is standing on the shoulders of so many researchers that Yang Yuanzhao can promote this initiative, the only imperfect thing is that the researchers in electric welding can only provide some technical indicators after electric welding, how to make electric welding used on steamboats, and achieve considerable results, which still needs to be done practically.

Theory is theory, and practice is practice. Everything has to be tried to be able to be transformed into reality, Yang Yuanzhao also understood this qiē, so he chose the 300-ton dock to implement his plan, and now everything is ready. When all the equipment and personnel arrived, the welding work officially began.

This welding of the bow of the ship, in the past, could only be connected through the guò willow, through a large number of willow joints, and the mutual stability of each other. This is somewhat unfavorable in terms of the shape, weight and layout of the bow, and the machining workshop, through the guò 1200-ton hydraulic press, ensures that the 17 parts of the bow are formed at one time. The worker in charge of the interface also carried out a series of treatments at the position of the interface, the crane lifted the two parts, fixed them with brackets, and most of the preparation work for the electric welding has already been completed.

For the first time, of course, it was carefully prepared, and the welder used the most stable submerged arc welding, with a special solder buried between the two parts. The final result can already be deduced through guò calculations, when the welding begins, with the help of a welding machine. In the long-distance operation, the electric light flickered slightly, as if nothing had been done, and the two pieces of material, in the flickering of the electric light, combined into a whole. Submerged arc welding was successful.

Wang Benchu first stepped forward to check the welding results. He was the engineer responsible for the design and construction of this steamboat, because it was the first one. It is impossible to make greater changes, but in the subtle part of the guò engineer to fine-tune, and not the engineer of a large cargo ship, for the sake of secrecy, Yang Yuanzhao directly transferred from the northwest, the engineer of the 800-ton ordinary steamboat, the search of the whole country can still be found, Wang Benchu once worked in the Mawei shipyard, personally designed and participated in the design and construction of the 750-ton ordinary steamboat, was recruited to the northwest 2 years ago, has been in the Yellow River patrol battalion to do gunboat maintenance and construction work, this time was transferred here.

Wang Benchu has left his job for a few years, and when he was transferred here, he was still worried that he would not be able to complete this job, but Yang Yuanzhao's trust and the efforts of the workers made him calm down and complete the design of the steamboat than the gourd, without too many changes, and it was decent.

For this design, Wang Benchu had no bottom in his heart, and changed to the previous willow joint mode, which was better than the gourd painting scoop, he could design it casually, but electric welding was the first time, although Yang Yuanzhao said it was simple, according to the original arrangement, as long as the willow part was removed. Wang Benchu is a designer, he knows very well that the ship is a fine thing, any problem in any place, will affect the whole ship, he came to Baotou before he did not contact electric welding, after coming to the Yellow River patrol battalion, it is also a preliminary contact with electric welding, but it is just some steel structures and gunboats on the simple welding, can combine the two steel into one electric welding, it is simply magical.

But the application of electric welding to shipbuilding, this is still something that has never been thought of, the electric welding he touches, is not so strong, and there are huge flaws, this may be reluctant in the river, to the boundless sea, absolutely not, those welding joints and casting, will become the weakness of the ship, maybe the big waves come, there will be problems.

Wang Benchu understood this, but he didn't dare to mention who Yang Yuanzhao was, the supreme leader of the entire Northwest, the spiritual leader, what he said and the opinions he put forward could almost be verified, as if he was a prophet, and he was just a small engineer, with a huge difference, and he could only do his duty step by step.

But when the welding began, the whole welding process, let Wang Benchu open his eyes, submerged arc welding is famous for less smelting, less impurities, submerged arc calculation is good, can even achieve seamless welding, this in front of him is, as long as a little polishing, it can become a smooth and clean one, if it wasn't for him to see it with his own eyes before, it was two different parts, he even thought that these were originally in one.

With a sigh, Wang Benchu said: "Continue to operate, don't stop!" ”

Submerged arc welding can be prepared in advance, but not every part of the submerged arc welding, only relatively flat and regular, steamboats, only a limited part, is flat, can be used submerged arc welding, other parts, are curved.

However, compared with submerged arc welding, argon arc welding in the northwest is the best, which is also the most suitable for use in shipbuilding, with the help of argon protection, isolated from the oxidation of high temperatures, so that the hull is more smooth and clean, the highest level of electric welding in the northwest, for argon arc welding mastery of the most familiar 4 masters to do it together, belongs to the light of electric welding, lit up in the entire dock, Yang Yuanzhao with goggles, carefully looked at the whole process, two parts of about 3 tons, willow connection, it takes 5 days, It doesn't even include the manufacturing process of punching holes and willow joints, but with electric welding, plus preliminary processing and preparation, it only took 7 hours at most, and now, it depends on the effect of electric welding.

Steady and skilled welders, can complete the process of electric welding in the shortest time, quality and quantity, the 4 main welders, each of them has hundreds of successful experiences, almost 35 minutes later, the last welding gun, also extinguished the light, a piece of welding after the smell of burnt permeates, but everyone's eyes, are full of excitement.

Wang Benchu is also one of them, different from the submerged arc welding carefully prepared before, this is more irregular, but also on the ship, one of the more components, its success, on behalf of most of the structure of the entire steamship, can be processed by electric welding, compared with the previous willow joint, at least save a lot of space and weight.

The quality inspection personnel made a clean up, regardless of the grinding and cleaning, the special quality inspection personnel, holding the quality inspection equipment, testing the internal structure of the metal, firmness, and the deformation of the approximate object, almost 10 minutes later, the results came up, the same as the real yàn, the strength of the metal is more than the willow joint, the weight is reduced by more than 100 kilograms, the most important thing is that the smooth and smooth surface, for the resistance of water, can be reduced to the lowest degree, after removing the willow joint, Penetration can even form a blade-like state, straight and sharp.

On the one hand, the fluid has not reached a certain program, on the other hand, it is also the ability of machining, the warships of this era, most of them use willow joints, there must be enough force points and willow joints, even if they are excellent workers, it is impossible to make the effect of willow joints perfect, different people have different styles, Barely combined, it's already good. Electric welding is different, with the help of advanced welding tools, the connection points are extremely smooth and strong, which can solve this problem well.

The role played by electric welding, really shocked everyone, especially the people who have a certain understanding of the ship, itself occupies about 40% of the shipbuilding willow joint and installation process, because of the joint effect of electric welding and cranes, the efficiency is extremely high, those like building, drilling, willow jointing process, all replaced by pendulum blocks and electric welding, it may have taken about 40 days to complete the steamboat, only about 12 days, has begun to take shape, the main structure has been basically formed, next, is the interior decoration and power unit installation, The efficiency is more than twice as high.

As an engineer from a shipyard, even if it is no longer in the shipbuilding industry, but Wang Benchu is very clear that the utilization rate of the dock is very critical for the shipyard, and the 800-ton steamship saves more than 20 days of time.

Seeing that electric welding has begun to bear fruit, even the welders and Wang Benchu are also discussing how to improve efficiency, the initial use of electric welding, many aspects are not proficient, just barely completed this steamboat, it is estimated that in 5 days you can get out of the dock, sea trials and interior decoration, the lessons learned along the way, summed up, can be squeezed and promoted a lot, for example, when the bow is processed, the stern can be welded, and the temporary crane can be more professional, Save the time of splicing, the work sequence of the workers can also be simply adjusted, so that every step is in order, similar to these, Yang Yuanzhao waved his hand, and handed it over to them with confidence, these professional things, or have professional personnel to operate the best.
