Detail
There are many factors that affect the welding quality of used welded pipe machine, and these factors interact and restrict each other in the same system.
When one factor changes, other factors will also change as it changes. Therefore, in the high frequency adjustment, it is not enough to pay attention to the local adjustment of the frequency, power, current or squeeze amount of the used welded pipe machine.
This adjustment must be based on the specific conditions of the entire molding system, comprehensively considered from all aspects related to high-frequency welding, and adjusted by excluding all influencing factors one by one.
Below we break down the main factors in the high-frequency welding process, there are the following eight aspects, we will introduce the ⑦Impedance device in detail. ⑧Welding extrusion force
⑦Impedance device in detail.
The function of the impedance device is to strengthen the skin effect and proximity effect of the high-frequency current. The impedance device is generally made of M-XO/N-XO type iron oxide, and is usually made into a magnet rod of φ10mm*(120-160)mm. Bundled in a heat-resistant, insulating shell, the inside is cooled by water.
The setting of the impedance device should match the pipe diameter to ensure the corresponding magnetic flux. To ensure the permeability of the resistor, in addition to the material requirements of the resistor, it is also necessary to ensure that the ratio of the cross-sectional area of the resistor to the cross-sectional area of the pipe diameter is large enough. In the production of high-precision high-grade pipes, it is required to remove internal burrs. The resistor can only be placed in the internal burr removal device, and the cross-sectional area of the resistor will be correspondingly smaller. At this time, the effect of using the concentrated fan layout of the magnetic rod is better than that of the ring. Layout.
The distance between the resistor and the welding point also affects the welding efficiency. The gap between the resistor and the inner wall of the pipe is generally 6-15mm, and the upper limit value is used when the pipe diameter is large; the resistor should be placed concentrically with the pipe, and its head and the welding point The distance is 10-20mm, the same is true, when the pipe diameter is large, the larger value is used.
⑧ Welding extrusion force
Welding pressure is also the main parameter of high frequency welding. Theoretical calculations believe that the welding pressure should be 100-300MPa, but the actual pressure in this area is difficult to measure in actual production. It is generally estimated based on experience and converted into the amount of squeeze on the edge of the pipe. Different wall thicknesses take different extrusion amounts. Usually, the extrusion amount below 2mm is: 0.5t~1t for 3-6mm; 0.5t for 6-10mm, and 0.3~0.5t for more than 10mm.
In the production of thick-walled pipes, such as API steel pipes, gray spot defects in welds often appear. Gray spot defects are refractory oxides. In order to eliminate gray spots, Baosteel and other manufacturers have adopted increased extrusion force to increase welding residuals. The method of measuring, the extrusion margin of 6mm or more steel pipes can reach the material thickness of 0.8~1.0, and the effect is very good.
Therefore, if you fully understand that the impedance device in detail and welding extrusion force will affect the welding quality of the used welded pipe machine, it is necessary to analyze other aspects of the welding quality of the used welded pipe machine before you can summarize the method and deal with it. The next issue will introduce Common problems in high frequency welding and their causes/solutions. If necessary, you can continue to pay attention to us.

The Role of Roller Conveyor Motors in Used Pipe Welding Machines
Time of issue : 2025-03-05
Used pipe welding machines refer to welding equipment that has been previously used and is resold, typically for producing welded steel pipes. In used pipe welding machines, the roller conveyor motor is a critical component whose role runs through the entire production process, directly affecting the equipment's operational efficiency, processing accuracy, and product quality. Below is an analysis of the main functions and importance of roller conveyor motors in used pipe welding machines.
1. Transporting Pipe Materials
The primary function of the roller conveyor motor is to drive the rollers, transporting pipe materials from one process to the next. During pipe welding production, the pipe material needs to go through multiple stages, including uncoiling, forming, welding, cooling, sizing, and cutting. The roller conveyor motor ensures smooth and continuous movement of the pipe material by controlling the rotation of the rollers, preventing jams or deviations.
2. Ensuring Production Continuity
In used pipe welding machines, the stable operation of the roller conveyor motor is key to ensuring production continuity. If the motor fails, it may cause interruptions in material transportation, affecting the efficiency of the entire production line. Therefore, the reliability and durability of the roller conveyor motor are particularly important, especially in used equipment, where regular maintenance and care are essential.
3. Controlling Pipe Material Speed
The roller conveyor motor controls the speed of the rollers through a speed regulation device, thereby adjusting the transportation speed of the pipe material. During the welding process, the transportation speed of the pipe material must match the welding speed to ensure weld quality. The precise control capability of the roller conveyor motor directly affects welding results and production efficiency.
4. Improving Processing Accuracy
The smooth operation of the roller conveyor motor helps reduce vibrations and deviations during material transportation, thereby improving processing accuracy. In used pipe welding machines, the performance of the roller conveyor motor may decline due to equipment aging, so regular inspection and maintenance are necessary to ensure its operational precision.
5. Adapting to Multiple Specifications
Roller conveyor motors are typically equipped with speed regulation functions, allowing them to adapt to the production of pipes with different specifications. For example, when producing thin-walled and thick-walled pipes, the motor needs to adjust its speed to meet different processing requirements. This flexibility enables used pipe welding machines to fulfill diverse production needs.
6. Energy Saving and Efficiency
Modern roller conveyor motors are often designed for high efficiency and energy savings, reducing energy consumption and improving production efficiency. In used pipe welding machines, if the motor is aging or its performance declines, energy consumption may increase. Therefore, it is recommended to upgrade or replace the motor to enhance the overall energy efficiency of the equipment.
7. Reducing Equipment Wear
The smooth operation of the roller conveyor motor can reduce wear on other components of the equipment. For instance, if the motor operates unstably, it may cause premature wear on rollers, bearings, and other parts, increasing maintenance costs. Thus, in used pipe welding machines, the condition of the roller conveyor motor directly impacts the equipment's service life.
8. Automation Control
In modern pipe welding production lines, roller conveyor motors are often integrated with PLCs (Programmable Logic Controllers) and sensors to achieve automated control. In used pipe welding machines, if the roller conveyor motor supports automation functions, it can significantly improve production efficiency and product quality.
9. Safety
The stable operation of the roller conveyor motor is also closely related to production safety. If the motor fails, it may lead to material pile-ups, equipment jams, or even injuries. Therefore, in used pipe welding machines, the safety of the roller conveyor motor cannot be overlooked.
10. Maintenance and Care
In used pipe welding machines, the maintenance of the roller conveyor motor is particularly important. Since the equipment has been used for a certain period, the motor's performance may have declined. Regularly checking the motor's insulation, lubrication, and operating temperature can extend its service life and ensure stable equipment operation.
Conclusion
The roller conveyor motor plays a vital role in used pipe welding machines, with its functions covering material transportation, speed control, processing accuracy, energy efficiency, and more. For used equipment, the condition of the roller conveyor motor directly affects the overall performance and production efficiency of the equipment. Therefore,
