The main features of tank welding machine.
l Reasonable design and free adjustment. Tank welding machines with different discharge frequencies can be selected according to different metal materials to achieve the best repair effect.
l The heat affected area is small. There is no heat input during the instant of cladding, so there is no deformation, undercut and residual stress. No partial annealing will occur, and no need to re-heat treatment after repair.
l The impact of tank welding machine is extremely small. The welding machine overcomes the impact of ordinary argon arc welding on the periphery of the work piece in the welding repair process. It is also possible to repair the work surface with no allowance.
l High repair accuracy. The surfacing thickness ranges from a few microns to a few millimeters, and only needs to be polished and polished.
l High welding strength. Due to the full penetration of the material on the surface of the work piece, a strong bonding force is produced.
l Adopt ring precision control.
How to use a tank welding machine?
l Check the connection
After completing the wiring of the tank welding machine, you must check each installed connector to confirm that it is well connected before starting to operate the equipment. Its contents include:
1. The line connection is correct and reasonable, and the grounding must meet the specified requirements
2. The magnetic work piece gripper shall not have attached metal particles and splashes on its contact surface;
3. The coiled welding cable should be unrolled before use to avoid overheating and insulation damage;
4. When it is necessary to alternately use different lengths of cables, insulating joints should be provided to ensure that useless lengths can be disconnected when not needed.
There must not be any leakage of cooling water, shielding gas or engine oil that affects the safety of welders.
l Work suspension
When the welding work is suspended (for example, during breaks), the output terminal of the equipment or welding machine must be turned off or the power supply must be cut off.
l Mobile welding machine
When you need to move the tank welding machine, you must first cut off the power supply at its input end.
l Equipment not used
The metal electrode and carbon electrode must be removed from the welding tongs when not in use to eliminate the risk of electric shock to personnel or conductive objects. The welding tongs must be placed out of contact with persons, electrical conductors, flammable objects or compressed air bottles when not in use. The welding torch of the semi-automatic welding machine must be properly placed when not in use to avoid accidental activation of the gun body switch.
All arc welding equipment must be maintained at any time and kept in a safe worki
Tank welding machine is the process of joining metal parts using various fusible alloys. The melting point of the solder is lower than that of the material to be soldered, so that the part will end the soldering through inter molecular contact on its surface without being melted.

What is the working principle of tank welding machines?
Tank welding machines can be divided into soft welding and hard welding. The temperature of soft welding is lower than 450℃, and the temperature of hard welding is higher than 450℃. Hard welding is usually used for metals such as silver, gold, steel, copper, and its welding point is much stronger than soft welding, and its shear strength is 20 to 30 times that of soft welding. The above two types of thermal connections usually use the term soldering, because in both cases molten solder is written into two elongated gaps between the clean and close solid metal surfaces of the device.
Tank welding machines ensure the continuity of the metal. On the one hand, two metals are connected by bolts or physical attachments to each other, showing a strong metal whole, but this connection is not continuous. Sometimes if there is an oxide insulating film on the metal surface, they may even Right or wrong physical contact.Another disadvantage of mechanical connection compared with welding is that the contact surface continues to oxidize, resulting in an increase in resistance. In addition, vibrations and other mechanical shocks can also loosen the joint. Welding eliminates these problems. The tank welding machines do not move relative to each other, the contact surface will not be oxidized, and the continuous conduction method can be maintained.
What is the purpose of using tank welding machines?
Tank welding machines welding is a process of fusion between two metals, mainly for the purpose of dissolving some of the metal in contact with the solder in the molten state, and the surface of the metal being welded often has a thin oxide film that cannot be dissolved by the solder. The flux is used to remove this oxide film. The tank welding machines welding process usually includes:
l 1) Melting of the flux to remove the oxide film on the surface of the welded metal;
l 2) Melting the solder makes the impure substances and lighter flux suspended in it float to the surface;
l 3) Some dissolve some metal connected with solder;
l 4) Cool and end the melting of metal and solder.
Through temperature changes, humidity, vibration, etc., even a bad solder joint can cause some or all of the system to lose control. There are countless welding points in the equipment, and the reliability of these welding points should even be higher than the equipment itself.
For the purpose of using tank welding machines, research in this area has led to the addition of knowledge of materials and their properties, and many developments have been made in the possible welding processes. Welding technology is an accompanying technology.
With the development of the electronics industry, more useful packaging technologies and smaller components will certainly continue to emerge. Welding technology will also continue to be developed to meet the needs of the electronics industry and environmental issues. This is why welding is becoming more and more professional for technology professors who work in the electronics industry today!
What are the application significance of tank welding machines?
The auxiliary equipment of the tank welding machines includes gas welding glasses to prevent the operator from being damaged by the ultraviolet, infrared or other rays generated by the welding arc or other welding energy, the mask to protect the eyes, face and neck of the welder during arc welding, white work clothes, welder gloves and protective guards.
l Energy efficient.
The energy saving of the electric welding machine is embodied in two aspects: energy saving at no load and energy saving at load. According to relevant statistics, in 2008, the demand for tank welding machines in the domestic welding industry was 890,000 units. If all electric welding machines are used, it can directly save 43,000 tons of copper, 64,000 tons of steel, and save 680 million KW.H of electricity. It saved 566,500 tons of coal, 10.34 million tons of water, and reduced 1,144,500 tons of CO2 emissions. It can be seen that vigorously promoting tank welding machines has huge economic and social benefits.
l Stable performance
Since the working frequency of the tank welding machines is above 20KHZ, it has a faster response speed, and the droplet transfer can be subdivided into multiple stages for control. For CO2 gas shielded welding, spatter can be greatly reduced. For pulsed melting pole MIG/MAG welding, the stability of jet transition can be effectively controlled, and the droplet transition and the movement of the wire feeding mechanism can be combined to further control the melting. During the dripping transition process, a good weld formation is obtained and the welding performance is stable. These are things that traditional rectifier welding machines cannot do.
l Centralized control
The tank welding machines uses a large number of digital controllers such as single-chip microcomputer, DSP, FPGA, etc., and realizes the network communication between multiple welding machines or the upper computer and the welding machine through Ethernet and field bus. It not only solves the problem of coordinated operation of multiple welding machines, and facilitates centralized control in the welding process, but also realizes the setting or monitoring of remote welding machine parameters, making remote fault diagnosis and maintenance of tank welding machines possible.
It is not easy to maintain pipe spool fabrication line. Whether it is used in the oil and gas industry, power plants, chemical plants or other infrastructure projects, the pipe spool fabrication line usually contains hundreds of components and thousands of processing steps. Therefore, it is very important to maintain the pipe spool fabrication line.
Here is the content list:
l Line maintenance
l Pipeline repair
l The advantages of choosing WINCOO to repair and maintain the tube shaft production line.
The maintenance of the pipe spool fabrication line includes inspection of pipeline corrosion and anti-corrosion; inspection of pipelines for oil leaks; inspection of valves along the line; inspection of the loss of hydraulic structures and coatings along the line; inspection of signs of damage, etc. Once the pipeline line and equipment are found to be faulty, the pipe spool fabrication line should be repaired or updated in time.
Due to the long line of the pipe spool fabrication line, it may be damaged by man-made and natural disasters at any time. Therefore, it is necessary to conduct line inspection and maintenance of the pipe spool fabrication line frequently. In addition, there is also a dedicated pipeline maintenance team equipped with necessary mobile equipment, earth moving equipment, welding and blocking equipment, and communication tools, so that they can be prepared for emergency repairs at any time.
l Pipe spool fabrication line anti-corrosion inspection
Routine pipe spool fabrication line anti-corrosion inspections include: regularly testing the protection potential along the pipeline; using an anti-corrosion layer detector to check the integrity of the pipe's anti-corrosion layer on the ground. The inspection of corrosion in the old pipeline is a complicated task, and it is usually carried out with a cup-type pipe cleaner with a testing instrument.
The testing equipment of the pipe spool fabrication line includes a magnetic flaw detector to detect internal corrosion and an ultrasonic thickness gauge to detect the thickness of the pipe spool fabrication line. The running distance is calculated by the number of revolutions of the support wheel, and all the tested parameters are converted into signals and recorded on the tape. After the inspection, the tape is interpreted by the computer, which can indicate the corrosion degree and location of the pipeline.
l Pipe spool fabrication line oil leakage inspection
Mainly rely on line inspectors to inspect the pipe spool fabrication line. In order to ensure the safety of residents and enterprises along the route, all countries have formulated oil and gas pipeline safety technical specifications, which are strictly supervised and implemented by government departments. If leakage occurs in the pipe spool fabrication line, report it to the competent authority immediately and check the cause of the accident on site.
Heavy rains and floods will cause soil erosion on the pipe spool fabrication line and damage to the embankment, resulting in exposed, suspended or even broken underwater pipelines. These situations are mainly discovered by line inspectors. Line patrol personnel usually walk on the ground or fly in the air to patrol the line. The maintenance work of the pipe spool fabrication line must be implemented in accordance with the detailed line engineering as-built drawing!
The most prominent part of the maintenance of the pipe spool fabrication line is the handling of large accidents such as leak repair and pipe replacement. If the leak is caused by corrosion and perforation, you can use a fixture to plug the leak on the pipe and then perform repair welding.
If the pipe spool fabrication line is severely damaged or deformed, the pipe must be removed and replaced with a new pipe section. The oil and gas leaked when the pipe is cut off can easily cause a fire. When cutting off the pipeline at low places, it is necessary to prevent a large amount of oil and gas from leaking. Mechanical plugging devices are often used to plug the pipelines, and emergency repair operations are carried out without stopping the transportation.
The mechanical plugging method is to open a hole on the upstream and downstream of the pipe section to be replaced, and insert a plug with a cup into each hole to isolate the oil or gas at both ends, and then drain the oil in the damaged pipe section. Or gas, cut off the pipe section with a mechanical cutter, then insert two pigging balls into the cuts at both ends, and fill the gap between the pigging balls and the plug with nitrogen to prevent explosion during welding.
Put the equipped new pipe spool fabrication line in place, align and weld. After welding, lift the occluder out of the pipe and close the opening to complete the plugging and pipe replacement work. After the pipe spool fabrication line is repaired and operated, two pig balls will be recovered in the pig receiver tube of the downstream station. When plugging and replacing a pipe section, the bypass pipe can be drawn out before plugging to ensure uninterrupted pipe spool fabrication line delivery during the entire pipe replacement process.
The advantages of choosing WINCOO to repair and maintain the tube shaft production line.
Since the pipe spool fabrication line contains thousands of steps, each step is an opportunity for error. Therefore, carefully plan before sending the request for quotation (RFQ) to the manufacturer and proceed during the manufacturing of the pipe spool fabrication line. Careful monitoring and acceleration of the process contribute to successful, timely and profitable results. Adequate planning, preparation and scheduling early in the process is beneficial to project owners, builders and tube and shaft manufacturers!
