Continuous Longitudinal Tube Welding with Water Cooling Stability

Engineered for long-run longitudinal seam welding of stainless steel and aluminum tubes. Integrated water cooling system ensures stable laser output during extended production cycles. Available in 1500W, 2000W and 3000W fiber laser configurations.

✗ Laser power drift during long production runs due to heat buildup

✗ Inconsistent weld penetration along the longitudinal seam

✗ Tube deformation from excessive heat accumulation

✗ Frequent downtime for laser source cooling and recalibration

1. Integrated Water Cooling — Stable Laser Output

The closed-loop water chiller maintains constant laser source temperature. No power degradation even during 8+ hour continuous longitudinal welding operations.

2. Longitudinal Seam Precision

CNC-controlled tube rotation and laser head positioning ensure uniform penetration across the entire longitudinal weld seam. Consistent quality from the first tube to the last.

3. Low Heat Distortion on Thin-Wall Tubes

Fiber laser''s concentrated energy zone plus active cooling minimizes the heat-affected zone. Ideal for thin-wall stainless steel tubes (0.5mm and above).

4. High-Speed Continuous Production

Automatic feeding, clamping and welding cycle enables uninterrupted longitudinal tube processing. Welding speeds significantly faster than traditional TIG longitudinal welding.

Q: How does water cooling improve longitudinal tube welding quality?

The integrated water chiller maintains a constant laser source temperature throughout production runs. This prevents heat-related power drift, ensuring consistent weld penetration from the start to the end of each longitudinal seam, even during extended 8+ hour shifts.

Q: What tube materials and thicknesses can this machine weld?

The machine handles stainless steel, aluminum alloy and carbon steel tubes with wall thickness from 0.5mm to 3.0mm. Tube diameter and length capacity are customized based on your production requirements.

Q: Is this machine suitable for continuous tube mill production?

Yes. The water cooling system and automatic tube feeding mechanism are specifically designed for continuous longitudinal welding in tube mill environments. The CNC system maintains consistent parameters across thousands of tubes.

Q: What after-sales support is included?

12-month full warranty with remote video support, online technical assistance, spare parts supply, and optional on-site installation and operator training by Xinwei engineers.
