▸ Product Introduction

The JINGWEN LHQ Series is a complete, end-to-end laser tube mill designed to replace traditional, multi-step production methods. This sophisticated system automates the entire workflow: it uncoils raw material, forms it into a precise profile using high-quality molds, performs a flawless straight-seam weld using a high-power fiber laser, and cuts the continuous tube to the desired length with an integrated online laser cutter.

By replacing older technologies like high-frequency induction or TIG welding, the LHQ Series offers superior weld quality with a smaller heat-affected zone, resulting in a stronger, smoother, and more aesthetically pleasing seam. With minimal consumables and a highly efficient process, this production line delivers unparalleled productivity and a rapid return on investment for any large-scale tube manufacturer.

▸ Product Features

✅ Fully Integrated Production: 

Combines forming, online laser welding, and online laser cutting into a single, continuous, and automated process, drastically reducing labor and handling time.

✅ High-Speed, High-Volume Output: 

With processing speeds ranging from 0.2m to 50m per minute, the LHQ Series is engineered for maximum throughput to meet the most demanding production schedules.

✅ Superior Weld Quality: 

Fiber laser welding produces a clean, deep-penetration weld with minimal spatter and a narrow seam, often eliminating the need for post-weld scarfing or grinding.

✅ Exceptional Versatility:

 Capable of processing a wide range of materials and profiles, including round, square, rectangular, and custom shapes with diameters from Φ9.5mm up to a massive Φ630mm.

✅ Low Consumables & High Cost-Performance: 

The laser process requires no filler rods or welding electrodes, and the high efficiency of the system minimizes energy consumption and waste, leading to a significantly lower cost per meter.

✅ Precision Forming Molds: 

Utilizes high-precision welded pipe molds to ensure consistent tube dimensions and shape accuracy throughout the entire production run.
