What is tank welding machine?
How many kinds of tank welding machine?
What is the preheating method of tank welding machine?
Large storage tank automatic welding machine, large storage tank is used to store oil, natural gas, and other energy. This kind of tank because the body is too big, cannot be formed at a time, are made of steel plate, splicing. So the welding machine is needed in the splicing process. Manual welding is the simplest and most direct method, but because of its high cost and low welding speed. So automation equipment has been widely used. Large tank automatic welding equipment, we are also known as tank automatic welding machine, the following for you to introduce several commonly used automatic welding machine: horizontal welding machine, vertical welding machine and Angle flat welding machine.
How many kinds of tank welding machine?
The so-called horizontal welding machine is a kind of welding machine that welds steel plates horizontally in the storage tank prefabrication.
The so-called vertical welding machine is a kind of welding machine that welds steel plates vertically in the storage tank prefabrication.
The so-called Angle flat welder is a welder that welds the bottom plate and the corners in the storage tank prefabrication.
What is the preheating method of tank welding machine?
After the arc of the welding rod of the tank welding machine is started, the arc is slightly elongated. In the state that the arc is not extinguished, the end of the welding rod is melted and a few droplets fall down. At this time, the welding rod has reached the normal burning state. At the same time, the use of the tank welding machine The heat generated by the arc heats the weld start. If it is found that the surface of the spot-fixed weld at the start of the weld begins to show signs of melting, the electrode will press the arc towards the lower edge of the spot-fixed weld, and then weld upward; The electrode reduces the welding speed slightly and turns the arc upwards. At this time, the electrode pauses for a while, and the rear edge of the weld joint is broken down in advance, and a molten pool and a molten hole are formed, and the formed molten hole must ensure that the blunt edge of both sides is 1.0~1.5 mm. At this time, the seam has been connected, and the electrode can be welded normally.

In actual operation, in order to ensure that the installation quality of pipeline construction equipment meets the construction requirements, targeted solutions must be taken according to the problem and its cause. The following will explain the installation of pipeline construction equipment before, during and after installation.
Here is the content list:
l Regarding the control of pipeline construction equipment before construction.
l Regarding the control of pipeline construction equipment during construction.
l Regarding the control of pipeline construction equipment after construction.
Regarding the control of pipeline construction equipment before construction.
Before construction, in order to ensure that the material of the pipeline construction equipment used meets the industrial requirements, strict inspections need to be repeated, including repeated verification and review of the construction drawings, and careful inspection of the pipeline processing drawings to ensure that the pipelines in the drawings The processing regulations and calculated data meet actual requirements.
In addition, it is necessary to check whether the pipeline construction equipment required for installation has a quality certificate and whether the specifications and models of the pipeline correspond to the certificate, and whether it meets the corresponding installation requirements of the pipeline construction equipment.
Before construction, check the pipeline construction equipment for damage and other quality defects that affect the construction. In order to get a more accurate understanding of the pipe material, professional quality inspection instruments can be used. For example, high-pressure pipelines can be detected by the monitoring method of magnetic flaw detection. Ensure that the material of pipeline construction equipment meets industrial production requirements.
In terms of capital investment in the installation of pipeline construction equipment, manpower, materials, and instruments and tools used are the main capital consumption objects. Manufacturers need to have a detailed grasp of the use of funds to reduce costs as much as possible without affecting the quality of the project. When selecting manpower, low-skilled workers should be employed for jobs with low technical requirements. When selecting materials, pipeline construction equipment is often selected for comparison. Before construction, it is also necessary to conduct professional skills training for construction personnel to enhance their work skills.
Regarding the control of pipeline construction equipment during construction.
During the installation process, when the pipe is cut according to the drawings, it is necessary to use the corresponding operating tools and methods to cut according to the construction requirements and the pipe material to avoid damage to the pipe. When connecting pipes, the main construction methods are hot bending and cold bending.
Hot bending is performed in the pipeline construction equipment installation process after heating treatment, specialized functional personnel make it deform according to the construction requirements; cold bending is carried out at room temperature, the pipeline construction equipment deforms according to the construction requirements. Since heating will cause mechanical deformation of the pipeline, cold bending processing methods are mostly used in the construction process. In hot bending, different heating fuels, heating pipeline construction equipment, and heating techniques must be used according to different pipeline materials and construction requirements, and the heating temperature must be strictly controlled.
The hot-bent pipes must be maintained after installation to ensure their quality and durability. When welding, due to the different materials of the pipeline and the different connection methods of the pipeline during the laying process, the welding tools and techniques selected will be different. The welding technology requires high requirements, and the construction personnel need to have good experience and technology to make the pipeline can be Therefore, experienced technicians should be selected for the welding process during the installation of pipeline construction equipment, and professional equipment should be used for testing after the welding is completed to see if seamless welding has been achieved to meet the engineering requirements.
Regarding the control of pipeline construction equipment after construction.
After the completion of the pipeline construction equipment, quality inspection and maintenance of the pipeline are required. When performing quality inspections, professional monitoring equipment is generally used, such as radiographic inspection, which can achieve non-destructive inspection. When the test is in progress, a unified test standard shall be adopted in compliance with the relevant technical standards, with special attention to whether the units used are unified.
After the pipeline construction equipment is installed, in order to better ensure the quality of the pipeline, it needs to be treated with anti-corrosion treatment. Generally, paint is applied to isolate the pipeline and the air in the water and oxygen from chemical reaction and rust. Extend the service life of the pipeline, and also improve the safety of operations for those who perform production operations.
Pipeline construction equipment is widely used in industrial production and has strict quality requirements. Due to the different pipeline construction equipment used in different industrial production environments, it is easy to have some problems during the installation process, which will affect the quality of the installation project. To ensure pipeline construction the installation quality of equipment meets the requirements of industrial production, and the installation process needs to be carried out in strict accordance with the construction requirements.

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.
