1、 Overview of Small Pipeline Laser Welding Equipment

Small pipeline laser welding equipment is a precision welding system that uses high-energy density laser beams as heat sources, designed specifically for the connection and repair of various metal pipelines. The system mainly consists of a laser generator, an optical transmission system, a precision motion platform, a gas protection device, and an intelligent control system, with the characteristics of compact size and flexible operation.

Laser generators usually use fiber lasers or semiconductor lasers with a power range of 500W-3000W, which can be precisely adjusted according to different pipe thicknesses. The optical transmission system guides the laser beam to the welding site through high-quality mirrors and focusing lens groups, and the spot diameter can be controlled within the range of 0.1-0.5mm, achieving high-precision energy input. The precision motion platform is driven by servo motors and equipped with high-precision guide rails, with a positioning accuracy of ± 0.02mm, meeting the uniformity requirements of pipeline circumferential welding.

2、 Technical features and advantages

Non contact processing: Laser welding does not require physical contact with the workpiece, avoiding mechanical stress deformation that may be caused by traditional welding, and is particularly suitable for connecting thin-walled pipelines.

Small heat affected zone: The laser energy is highly concentrated, and the heat input is only 1/3-1/5 of traditional arc welding, significantly reducing thermal deformation and maintaining the original mechanical properties of the pipeline.

Excellent welding quality: The weld seam is aesthetically pleasing, with a defect rate of less than 0.5% for porosity, slag inclusion, and other defects. The welding strength can reach over 90% of the base material.

Wide adaptability: can weld various metal pipes such as stainless steel, carbon steel, aluminum alloy, titanium alloy, etc., with a diameter range from 3mm to 150mm.

High degree of automation: equipped with visual positioning system and weld seam tracking technology, it can achieve automated welding with a repeat positioning accuracy of ± 0.05mm.

3、 Typical application areas

Medical device manufacturing: used for seamless welding of precision stainless steel conduits and minimally invasive surgical instrument fittings, meeting the strict requirements of the medical industry for cleanliness and biocompatibility.

Automotive exhaust system: Achieve efficient connection of thin-walled exhaust pipes, with welding speeds up to 3-5 m/min, significantly improving production efficiency.

Semiconductor equipment: used for welding ultra-high purity gas transmission pipelines, ensuring no pollution, no leakage, and meeting the special environmental requirements of semiconductor manufacturing.

Aerospace: Used for the repair and manufacturing of aviation hydraulic pipelines and fuel pipelines, with a welding seam pass rate of over 99% through X-ray inspection.

Home appliance industry: Precision welding of copper pipes for air conditioning and refrigeration pipelines for refrigerators, with single point welding time controlled within 0.5 seconds.
