What You Need to Know about Laser Cutting for Heavy Tube

With the rapid development of industrial manufacturing, the demand for raw materials has increased significantly, fuelling the widespread use of heavy metal tubes. These tubes are widely used in heavy machinery, steel buildings, building construction, machine building, bridge construction, greenhouses and communication towers. The processing of special sizes and large diameter tubes has always been a challenge for the manufacturing industry. Heavy duty laser cutting machine is able to accurately process oversized diameter and thickness tubes, providing highly customized solutions for a wide range of industries and driving manufacturing to greater excellence and scale.

The Best Laser Cutting Machine for Heavy-Duty Pipe

Heavy-duty pipes are steel pipe products with wall thicknesses typically exceeding 3mm, offering high load-bearing capacity along with exceptional strength and stiffness. These pipes not only possess excellent compressive properties but can also endure significant bending and torsional forces, making them reliable structural supports for various complex projects. Traditional cutting methods, however, suffer from low efficiency and poor processing quality, making it challenging to meet the demands for high-precision and intricate cutting.

In contrast, laser cutting for heavy tube provides notable advantages. It eliminates the need for molds, significantly reducing new product development time, and features fast cutting speeds and high precision. Laser tube cutting machines can precisely cut open holes, achieve broken cuts, create coherent lines, and handle complex shapes, meeting increasingly stringent process requirements.

Applicable pipes include round pipes, rectangular pipes, profiled pipes, oval pipes, OB pipes, angle iron, channel steel, and other metal pipe fittings and profiles of various materials and specifications. This technology serves multiple industries such as engineering machinery, locomotive manufacturing, petroleum pipelines, agricultural and forestry machinery, ladder fences, smart homes, fitness equipment, metal furniture, office desks and chairs, and bus manufacturing.

Traditional laser tube cutting machines are often limited by the length, diameter, weight, and metal type of the pipes when processing heavy-duty pipes. Conventional laser tube cutting machines can only handle round and square pipes up to 6 meters in length, and the weight of individual pipes is also restricted, making them unsuitable for cutting heavy-duty pipes effectively. To address these limitations, Dapeng Laser has developed a specialized heavy industrial metal laser cutting machine.

Auxiliary Gas for Heavy-duty Fiber Laser Tube Cutting Machine

When using a fiber laser tube cutting machine, auxiliary gases are required. The choice of auxiliary gases typically includes oxygen, nitrogen, and compressed air:

1. Compressed Air

   – Suitable for cutting aluminum plates and galvanized steel plates, reducing oxide films, and saving costs.

   – Generally used for thicker plates with less demanding surface cutting requirements.

2. Nitrogen

   – As an inert gas, it prevents oxidation of the plate surface during cutting, especially useful for preventing scorching (common in cutting thicker plates).

3. Oxygen

   – Primarily functions as an assist gas, accelerating cutting speed and increasing cutting thickness.

   – Suitable for cutting thick plates, high-speed cutting, and thin plates, such as large carbon steel plates and thick carbon steel structural components.

While increasing gas pressure can enhance cutting speed, excessively high cutting speeds may lead to decreased efficiency. Therefore, when tuning the machine, attention should be paid to adjusting the gas pressure for optimal cutting performance.

1. Extensive Adaptability to Various Pipes

The laser tube cutting machine employs the FSCUT3000S system, specifically designed for pipe cutting. It can handle not only large-diameter round and square pipes but also various profiles (such as rectangular pipes, elliptical pipes, channel steel, angle iron, I-beams, slats, profiles, special-shaped pipes, etc.) with high precision and efficiency. This significantly expands the processing range, enhancing the versatility and application value of the equipment.
