What are the advantages of orbital welding machine?

The application range of the orbital welding machine is greatly increased, the structure is simple, the cost is low, the purchase cost of the user can be reduced, the installation operation is convenient, the auxiliary operation time is short, and the work efficiency is high. The support flexible rail includes two parallel rails, and each rail includes a strip substrate.

What are the technical requirements when using the orbital welding machine?

Orbital welding machine shall not be used if the rail has the following conditions:

1. The rail is judged to have internal damage or serious surface injury.

2. The depth of the pit after the top surface of the rail head is damaged and polished:

Weld repair on the line exceeds 8 mm;

Solder repairs over 10 mm outside the line.

3. For scratches, spalling, falling blocks and welding joint wear, low collapse, etc. on the top surface of the rail head, the allowable length of welding repair shall meet the following requirements:

For rail joints (including welded joints) wear and low collapse, the allowable one-time welding repair length is 300 mm, and if the damaged length exceeds 300 mm, it should be divided into two sections for welding repair.

For defects and damages such as scratches, spalling and falling blocks on the top surface of the rail head, the length of one welding repair is allowed to be 200 mm. If the length exceeds 200 mm, it should be divided into two sections for welding repair.

When the rail joints are worn, slumped, scratched and peeled off at the same time, the scratches and peeled off blocks should be dealt with first.

What are the fields of application of orbital welding machines?

At present, the development of railways is mainly in the direction of high-speed passenger cars, subway passenger cars, light rail cars, high-speed heavy-duty trucks, etc. In order to achieve these needs, it is necessary to reduce the weight of trains. A common practice now is 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, and increase the 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 the orbital welding machine for processing and manufacturing.
