What are the features of the orbital welding machine?
At present, the development of railways is mainly towards high-speed passenger cars, subway passenger cars, light rail cars, high-speed heavy trucks, etc. To meet these requirements, it is necessary to adjust the weight of the trains. Nowadays, it is common practice to use aluminum alloy materials in the manufacturing process of passenger cars. Because aluminum alloy materials have the characteristics of light weight, corrosion resistance, smooth appearance, complex curved surfaces and high specific strength, they can effectively reduce the resistance and quality of passenger cars. Increased overload. In order to effectively improve the processing efficiency of aluminum alloy materials, it is necessary to change the traditional processing method and use the welding technology of orbital welding machine for processing and manufacturing.
(1) Welded parts preparation: Given the high hardness of rail steel, it is difficult to process the groove on site. Therefore, the orbital welding machine adopts the docking method and uses the existing end surface of the rail as the working surface. If the end face is heavily corroded, the angle grinder must be used to polish the surface bare.
(2) Determination of the impact gap: Given the height of the rail itself, the gap must not be too small, otherwise the welding wire for welding work cannot penetrate it, so it is necessary to reserve enough gap.
(3) Welding preheating: In the preheating process of orbital welding machine, a gas welding torch is used for preheating, and an infrared temperature measuring gun is used to ensure that the preheating reaches the specified temperature.
(4) Shock surface process: The entire welding process adopts the multi-layer multi-pass welding process. Although this process is relatively inefficient, it can ensure the weld strength and temperature between the layers.
(5) Heat treatment after welding: The heating process of the orbital welding machine uses a gas welding torch. After heating to the specified temperature, asbestos felt is used for heat preservation to prevent the appearance of cracks after welding.
(6) Grinding the workpiece after welding: The orbital welding machine keeps the weld seam and the base metal of the rail smooth.
The biggest feature of orbital welding machine is small-scale local heating, high heating efficiency, easy operation, which is very suitable for fast heating and cooling of high manganese steel welding, and also suitable for welding repairs of local defects on rails. It is currently the most widely used method for welding rails and track grooves. Methods. However, it must be noted that the orbital welding machine for rail welding must be properly preheated. Due to local heating and rapid cooling of the rail, slightly abnormal brittle structures such as martensite and bainite can be generated, which increases the brittleness of the rail. Preheating prevents abnormal tissue formation.

As we all know, industrial buildings include a series of projects, such as oil refineries and chemical plants and power plants. This type of structure involves dense pipe spool fabrication lines, which connect various equipment and transport process fluids and gases.
Here is the content list:
l Introduction of two engineering stages of Pipe spool fabrication line.
l The installation and welding of Pipe spool fabrication line can be divided into two types
l Why are pipes prefabricated in the Pipe spool fabrication line?
Due to the compressed construction period and limited on-site space, industrial construction projects rely heavily on off-site manufacturing and assembly. Therefore, the pipe spool fabrication line is divided into two stages: pipe prefabrication and on-site installation.
Pipe spool fabrication line timely supply of spools to the module yard and installation site is the key to the success of the entire project! First introduce the pipeline prefabrication stage of the pipe spool fabrication line.

The pipe spool fabrication line is made from many raw pipes and pipe fittings in the manufacturing plant. Cut the unprocessed pipe to the required size, then move it together with the pipe fittings to the fittings table, where certain components are assembled together (ie temporarily connected), and the final sub-assembly (part of the final pipe) The welding operation (ie permanent connection) will be continued, and then returned to the assembly table and assembled with other spool components to form a pipe spool fabrication line.
l Coil and welding
l Positioning and welding
Rolling assembly and welding in the pipe spool fabrication line means that the main pipe can be rotated by the rolling mill, and the assembler or welder can perform the operation without changing its position. When the branch of one or more main pipes exceeds the welding position, Positional assembly and welding can be performed.
In addition, under the restriction of the removal of the pipe spool fabrication line, the assembler or welder must move around the main pipe to complete the assembly or welding. Positioning assembly and welding usually take more time than roller assembly and welding. Minimizing the number of positioning and welding is one of the goals of the pipe spool fabrication line sequence.
Workshop prefabrication of the pipe spool fabrication line is an effective method that can reduce on-site installation costs while providing the highest quality finished products. Pipe spool fabrication line usually uses flange connection to facilitate connection with other spools.
The manufacturing of these pipe spool fabrication line is usually performed by a professional manufacturing company equipped with the required infrastructure. As a professional manufacturer, WINCOO works according to the defined quality management standards to ensure the accuracy of manufacturing, so as to realize the on-site drawstring installation and maintain the required technical parameters defined by the customer!If you want to know more about high-quality tank welding machine products, you can also contact us at any time.
The installation of pipeline construction equipment is one of the necessary parts in the pipe construction solution, and the installation and construction of pipeline construction equipment is a very important stage in project construction. Due to various factors in the project construction, there are many problems in the installation of pipeline construction equipment. To promote the improvement of the quality of industrial pipeline installation, certain measures need to be taken to control the installation quality of pipeline construction equipment to ensure the smooth construction of the project.
Here is the content list:
l Regarding the quality inspection of pipeline construction equipment installation.
l What are the quality control measures in the installation of pipeline construction equipment?
l Regarding the quality control of pipeline construction equipment after construction.
The sequence of installation of pipeline construction equipment is:
Measuring arrangement→cleaning the construction work area; construction road→conveying anticorrosion pipe→processing tank→distributing pipe→preparing nozzle; pipeline assembly→pipe assembly and welding→welding joint inspection→heat shrinkable casing (tape) bushing→ trench excavation →Appearance repair .
After the installation of pipeline construction equipment is completed, quality inspection is required. After pipeline construction equipment is installed and put into use, regular monitoring is required. Generally, radiographic inspection is used to inspect the quality of pipeline installation. This monitoring has a very good effect on the internal inspection of welded joints. It is widely used in the field of construction equipment installation. This method can also be used to make the quality of the pipeline meet the assessment standard.
Before installing pipeline construction equipment, clarify the construction plan of the construction technicians, use GB/T as the standard, and carry out construction in accordance with national standards and specifications; during the installation of pipeline construction equipment, strictly review the drawings for defects to ensure the rationality of the drawings, and the construction unit It is also necessary to make preparations for pipeline installation and construction, pipeline lumber, welding inspection, construction site management, etc.
Strictly follow the relevant requirements of pipeline construction equipment and pipeline construction requirements to improve the quality of construction. In order to ensure the quality of pipeline installation, quality control is required for key parts such as welding materials, welding processes, and welding seams to ensure pipeline construction equipment. Welding consumables, brands, specifications, etc. are required by the plan design, which are consistent with the project construction requirements to ensure the quality of installation.
① After the pipes, accessories and raw materials used for pipeline construction equipment enter the construction site, the supervisors shall check and accept them on site, and store the materials after passing the acceptance.
② Pipe joints and semi-finished products of pipeline construction equipment should be guaranteed not to be damaged during transportation and storage. When unloading, handle with care and not collide with each other; choose a flat place for stacking pipe joints.
③ The storage temperature of the rubber ring of pipeline construction equipment is between -5 and 30 degrees Celsius. It should not be exposed to ultraviolet light source and keep away from the heat source; the rubber ring and the items that easily affect the rubber ring should not be put together. If the pipeline construction equipment is being constructed In winter, hard rubber rings are not allowed.
④ For trench excavation in open-cut pipeline engineering, the section should meet the design requirements of construction quality, the original soil at the bottom of the trench should not be damaged, and the mechanical excavation should reserve a 200-300mm soil layer for manual excavation and leveling, and the bottom of the trench can be soaked by water And frost damage, if there is gravel soil, lime soil to backfill, the trench wall should be leveled to meet the requirements of construction design.
⑤ For concrete construction, when the pipe seat and flat foundation are poured in layers, the flat foundation should be shaved and rinsed; the concrete should be prevented from segregation, and the concrete should be cured after pouring.
⑥ When pipeline construction equipment is installed, visual inspection and internal cleanliness of the pipeline must be inspected.
⑦ The flexibility of pipe joints must meet the design requirements, and the rigidity must also meet the requirements.
⑧ In the stage of backfilling, the backfill height between both sides of the pipe and the top of the pipe before the hydraulic test of the pressure pipeline is greater than 0.5M, and the pressure-free pipeline shall be backfilled after the closed water test and the closed gas test have reached the standard.
After the completion of the pipeline construction equipment, the finishing work will begin. The unit needs to organize personnel to review the material documents involved in the pipeline installation, project reports, etc.; after the completion of the project, debugging and quality appraisal are required, and the pipeline professionals are organized to conduct quality appraisal of the installed pipelines. The dynamic control of the links will protect the completed pipelines.
In the later stage of the installation of pipeline construction equipment, in order to ensure the smooth completion of the project, the quality of the pipeline needs to be tested again to ensure that the pipeline installation does not have problems such as tilt and cracks, the welding parts are of good quality, and the pipeline is unobstructed. In the later period after the completion of the project, it is necessary to sort out each project data and work files involved in the pipeline construction, do a good job of archiving and backup to evaluate the quality of the pipeline, do a good job in risk control, and carry out the acceptance of pipeline construction equipment.
There are many influencing factors in the installation of pipeline construction equipmentt, so reasonable measures need to be taken to monitor and control every aspect of pipeline construction equipment. With the continuous expansion of the pipeline construction equipment construction industry, the use area is also expanding. Due to the importance of pipeline use, it is necessary to control the pipeline installation quality to ensure that the installation quality reaches the ideal standard!
