Tank welding machine is the process of joining metal parts with 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.
Here is the content list:
l Beginners should understand the basic structure of the tank welding machine in advance.
l What is the welding process of a tank welder that needs to be skilled?
l The application fields and prospects of beginners using can welders.
Tank welding machine welding 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.
Tank welding machine welding ensures 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.
In addition, vibrations and other mechanical shocks can also loosen the joint, tank welding machine eliminates these problems, the welding part does not move relative to each other, the contact surface will not oxidize, and the continuous conduction method can be maintained. Soldering is a process of fusion between two metals. When the solder is molten, it will dissolve some of the metal in contact with it. The surface of the metal to be soldered often has a thin oxide film that cannot be dissolved by the solder.
l Component inspection
l Exchange of defective components
l Check circuit function
l Melting the solder floats the suspended impurities and lighter flux to the surface
l Some dissolve some metal connected with solder
l Cool down and end the melting of metal and solder

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.

(1) Left welding method (right→left): small residual height, large width and small splash, which is easy to observe the welding seam, the welding process is stable, the gas shielding effect is good, but the depth of dissolution is shallow.
(2) Right welding method (left→right): The remaining height is large, the width is small, and the splash is large, which is convenient for observing the molten pool and the depth of the molten metal.
(3) Gun delivery method: zigzag swing.
(4) Flat fillet welding does not swing or swing slightly.
(5) The vertical angle is welded upward, and the triangular gun is used.
(6) Welding torch transition: stay on both sides of the molten pool and transition at the front 1/3 of the molten pool.
(7) Gun angle: perpendicular to the weld bead, at an angle of 80-90° along the direction of the gun.
(8) Test plate: the gap is 2.0-2.5mm, and the arc starting point is slightly smaller than the arc ending point. No blunt edge, anti-deformation 1°.
(9) To prevent defects: prevent the angle from melting - burn through the angle. No fusion between layers - pay attention to the gun angle.
The direction of the arc axis of the tank welding machine is perpendicular to the direction of the penetration depth of the weld. During welding, a water-cooled copper slider is used on the front of the weld, and a water-cooled gear row (or pad) is used on the back of the weld. The flux-cored wire is fed into the weldment and in the groove formed by the stopper, the four sides of the molten pool are constrained to realize single-sided welding and double-sided forming at one time. Tank welding machine is a high-efficiency welding technology and equipment.
In recent years, the promotion and application of tank welding machine in engineering has achieved good results, and in-depth research on the fusion welding mechanism of gas-electric vertical welding technology.
