What are the advantages of using tank welding machine?
①Tank welding machine has fast welding speed, good quality consistency, beautiful surface, and no uneven soldering phenomenon of manual welding. Equipment welding can avoid the influence of various human factors during manual welding, such as the influence of operator proficiency, the influence of physical condition, the influence of emotions, etc., so as to ensure the consistency and reliability of welding.
②Tank welding machine can reduce the number of operators and inspectors, reduce management difficulty and product cost. Now the labor cost is increasing year by year, and the annual recruitment is the most troublesome thing for the boss. The automatic welding machine can greatly reduce the number of employees.
What is the workflow of tank welding machine?
The girth welding equipment is tank welding machine. The main welding parameters of girth welding include welding current, welding torch speed, shielding gas flow, etc. At the same time, the clearance fit of welded joints also plays a crucial role. Under the existing conditions, the pipe ends are processed by lathes and repaired by fitters before welding. In this case, the dimensional accuracy of the short ends is difficult to meet the requirements of the drawings, resulting in uneven fitting gaps between the pipe ends and the pipe joints; In addition, during tack welding, if the pipeline is dislocated, it will also cause uneven clearance of the mating surface, so that the surface of the weld seam will be depressed after girth welding. In the welding process of the tank welding machine, the inside of the conduit is protected by argon gas. If there is no argon gas protection inside the conduit, the back of the weld will be poorly formed, and at the same time, it will cause oxidation.
What are the industrial characteristics of tank welding machine?
Industrial and self-propelled tank welding machines can be used to weld tanks and tubes. The submerged arc automatic welding machine is available in three versions: a standard version for monofilament, the latter specially designed for fillet and butt welding on tanks, and a light version for welding pipes with a diameter of Φ600mm or larger. The MLTW-T welding robot was developed for submerged arc welding with two articulated arms. Two-electrode submerged arc welding can be used, and two fillet welds can be welded at the bottom with high efficiency. The self-propelled welding robot is equipped with a speedometer-driven carriage. This guarantees a high degree of maneuverability.

Research background of tank welding machine.
Metal pipe welding is an important part of aeroengine. Fuel, lubricating oil, air, oxygen and other working media in each system rely on metal pipes for transmission. Aviation engine pipeline parts have many types, large quantity, and high accuracy grade. Therefore, the requirements for manufacturing precision and quality are very high, and the requirements for manufacturing methods are getting higher and higher.
The main manufacturing method of metal conduit is tank welding machine welding. The welding of metal conduits of aero-engines mostly adopts manual argon arc welding, flame brazing, induction brazing, etc. The above-mentioned welding method is easy to operate, simple in equipment, low in cost, and low in requirement for a single welded pipe. Pipes, so it is widely used for pipe welding.
However, these welding methods are manual operations, which require very high skills for tank welders. Usually the weld formation is not ideal, and defects such as weld deviation, dents, weld leakage and incomplete welding will occur.
The application prospect of tank welding machine in the future.
In recent years, with the large-scale application of metal conduits, the welding quality requirements of metal conduits have become higher and higher, and the welding of automatic welding machines has become an ideal conduit welding method.
In the 1990s, there was an automatic girth welder for welding metal pipes. The diameter of the welded pipe could cover all the metal pipes on aero engines.Therefore, in recent years, automatic welding machines have been applied to the welding of metal conduits of aero-engines and have achieved success.

At the production site of the tank hydraulic jacking system, due to the constraints of the production plan and technical conditions, the fault diagnosis personnel are required to accurately diagnose the faults of the hydraulic equipment, and the maintenance personnel are required to use the existing information and the technical conditions of the site. Minimize the workload of disassembly and assembly, save maintenance man-hours and costs, accurately find out the fault location and the cause of the failure and repair it, so that the tank hydraulic jacking system can resume normal operation.

General principles of tank hydraulic jacking system fault diagnosis.
Correct analysis of tank hydraulic jacking system failures is the prerequisite for troubleshooting. Most tank hydraulic jacking system failures do not occur suddenly. There are always signs before they occur. When the signs develop to a certain extent, the failure will occur.
The reasons for the failure of the tank hydraulic jacking system are various and there is no fixed pattern to be found. Statistics show that about 90% of tank hydraulic jacking system failures are caused by poor management. In order to diagnose failures quickly, accurately and conveniently, it is necessary to fully understand the characteristics and laws of tank hydraulic jacking system failures, which is the basis of fault diagnosis.
The following principles are worth following in the fault diagnosis of tank hydraulic jacking system:
① First, determine whether the working conditions and peripheral environment of the tank hydraulic jacking system are normal, and check whether the various conditions of the tank hydraulic jacking system meet the requirements of normal operation.
② Area judgment Determine the area related to the fault based on the tank hydraulic jacking system fault phenomenon and characteristics, and gradually reduce the scope of the fault.
③ Master the types of tank hydraulic jacking system faults and conduct a comprehensive analysis. According to the final phenomenon of the fault, gradually find out a variety of direct or indirect possible causes.
④ When verifying possible causes of failure, generally start from the most likely cause of failure or the most easily inspected place, which can reduce the workload of assembly and disassembly and increase the speed of diagnosis.
⑤ Establish a fault analysis table for the equipment operation tank hydraulic jacking system, which is a high-level summary of the use experience and helps to quickly make a judgment on the fault phenomenon.
The specific method of tank hydraulic jacking system fault diagnosis.
l The traditional method of finding hydraulic system faults daily is logical analysis and gradually approaching fault.
When the hydraulic system fails, there are many possible causes of the failure. Using the logic algebra method, list the possible failure causes, and then make logical judgments one by one according to the principle of easy first and then difficult, approach item by item, and finally find out the cause of the failure and the specific conditions that caused the failure.
l Fault diagnosis system based on parameter measurement
The idea of diagnosing faults by parameter measurement method is based on the fact that when any tank hydraulic jacking system is working normally, the system parameters are working near the design and set values. If these parameters deviate from the preset value during work, the system will malfunction or may malfunction.
That is, the essence of the failure of the tank hydraulic jacking system is the abnormal change of the system working parameters. During the measurement, there is no need to stop the machine or damage the hydraulic system. Almost any part of the system can be tested. Not only can the existing faults be diagnosed, but also online monitoring and potential faults can be predicted.
To summarize the fault diagnosis of tank hydraulic jacking system.
Apply the traditional logical analysis stepwise approximation method. It is necessary to analyze, judge and inspect all the above possible causes one by one, and finally find out the cause of the failure and the specific component that caused the failure. The diagnosis process of this method is cumbersome and requires a lot of assembly and disassembly, verification work, low efficiency, long construction period, and can only be qualitative analysis, the diagnosis is not accurate enough.
Application of fault diagnosis tank hydraulic jacking system based on parameter measurement. When piping the tank hydraulic jacking system, set a double ball valve and three ports at the outlet a of the pump, the front b of the reversing valve, and the inlet c of the cylinder, and the fault diagnosis detection circuit can be used to limit the system fault within a few seconds. In a certain area, the fault is diagnosed based on the measured parameter value.
Through the detection, the final cause of the failure is the serious internal leakage of the vane pump. After disassembling the pump, it was discovered that the vane pump stator caused abnormal wear due to poor lubrication, which caused internal leakage to increase and the tank hydraulic jacking system pressure did not increase. It was further discovered that the water in the water cooling tank hydraulic jacking system leaked into the oil, causing the oil to emulsify and lose its lubrication effect.
With the progress of society and the development of economy, people's demand for resources is increasing.From cars that need diesel to power plants that need oil.In short, oil, natural gas and other resources have become indispensable in daily life.But conventional rail and cruise transport is slow and uncertain.Gradually, people invented the method of pipeline transportation.
The transportation volume of pipeline transportation is large. Most of the pipeline is buried in the ground, which covers less land and is less constrained by terrain and objects, thus shortening the transportation distance.Sealed transportation, safe and reliable, long-term continuous and stable operation;Easy to manage, easy to realize remote centralized monitoring.
As a result, a large number of pipeline laying work was carried out in various countries, and thus the related companies specializing in pipeline laying work were also derived.We are specialized in providing pipeline construction equipment company.

Welding - Wikipedia
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal).. In addition to melting the base metal, a filler material is typically added to …
