Machine Introduction

The laser pipe cutting and welding integrated machine is a multi-functional intelligent laser device specifically designed for pipe and profile processing, integrating laser pipe cutting and laser pipe welding. It achieves all processing steps—including pipe cutting, hole drilling, grooving, beveling, slitting, butt welding—on a single machine, completing all processes in one setup. This significantly simplifies the process and improves accuracy and efficiency, making it a next-generation core equipment for the metal pipe and profile processing industry.

Working Principle

Laser pipe cutting uses a high-energy laser beam to locally melt/vaporize the pipe material. Combined with auxiliary gases (air, nitrogen, oxygen) to remove slag, it achieves high-precision cutting, hole drilling, beveling, and grooving of various profiles such as round pipes, square pipes, rectangular pipes, angle steel, channel steel, and I-beams.

Laser pipe welding controls the laser power, spot size, speed, and wire feed to rapidly fuse the pipe joint/weld area, forming a dense, high-strength weld with minimal deformation. It can perform butt welding, lap welding, fillet welding, and circumferential welding.

The integrated intelligent control equipment uses a CNC system to automatically switch cutting/welding process parameters, supporting graphic import, automatic edge finding, automatic centering, and automatic focusing for efficient and continuous operation.

Machine Detail

The laser pipe cutting and welding integrated machine truly realizes a "one-stop" solution for pipe processing, integrating high-precision pipe cutting and intelligent pipe welding. It is efficient, saves manpower, space, and costs, making it an ideal piece of equipment for the pipe processing industry to upgrade towards automation and intelligence. It is especially suitable for batch production of high-quality, high-requirement pipes.

Common power specifications cover 3kW-20kW, allowing for flexible selection based on pipe thickness, material, and processing efficiency requirements. Its core advantages lie in its electro-optical conversion efficiency exceeding 30%, far surpassing traditional lasers, resulting in lower energy consumption and more economical operating costs. Utilizing imported core optical components, it boasts excellent beam quality (M²≤1.2), producing an extremely small focused spot, ensuring precise cutting and stable welding.

Equipped with a dedicated tube-cutting laser head + a dedicated tube-welding laser head, this dual-component design supports two switching modes: First, a fully automatic electric switching mode, which allows for headframe switching and parameter matching within 60 seconds via a single command from the CNC system, requiring no manual intervention; second, a quick-change design using standardized interfaces, allowing for manual replacement in just 3 minutes, adaptable to flexible small-batch, multi-process manufacturing scenarios.

The complete system includes a pneumatic chuck, a self-centering clamp, and a high-precision rotary shaft as core components, fully adaptable to round, square, rectangular, and elliptical tubes, angle steel, channel steel, and various irregular profiles. The chuck adopts a three-jaw/four-jaw linkage design, with uniform and adjustable clamping force (0-5000N), which can be flexibly adjusted according to the tube diameter and wall thickness to avoid clamping deformation.

Industrial Water Chiller: Employs a high-precision temperature control system with an accuracy of ±0.1℃, providing continuous and stable cooling for the laser, laser head, and electrical components. This ensures constant temperature during 24-hour continuous operation, preventing performance degradation or malfunctions due to overheating.

Wire Feeding Mechanism: Driven by a servo motor, the wire feeding speed is adjustable from 0-10m/min with an accuracy of ±0.1mm. It supports various welding wires, including stainless steel, carbon steel, and aluminum wires, and can be flexibly matched to welding requirements, improving weld filling effect and strength.

Core Advantages:

Multi-functional, significantly reducing costs: One machine completes pipe cutting, hole drilling, beveling, pipe welding, and butt welding, replacing multiple machines used for traditional sawing, punching, grinding, and welding.

High pipe processing precision and minimal deformation; high cutting precision, smooth and burr-free cuts.

Narrow weld seam, small heat-affected zone, virtually no pipe deformation.

Aesthetically pleasing and high-strength weld seam: Uniform and dense weld seam allows most products to be used directly without extensive grinding and polishing, improving yield and appearance quality.
