Laser Welding Tube Mill
Smart Laser Precision Pipe Welding Line
The smart laser precision pipe welding line produces stainless and carbon steel pipe with a clean, narrow weld bead. Welded pipe from this class of line has replaced seamless tube across chemical, pharmaceutical, brewing, petroleum, food, automotive, textile and air conditioning industries.
Laser welding concentrates energy so the heated zone is tiny and deformation is minimal, which is what keeps precision pipe accurate after welding.

What is in the Smart Laser Pipe Welding Line
Laser welding concentrates energy so the heated zone is tiny and deformation is minimal, which is what keeps precision pipe accurate after welding.
- 01Precision and qualityMinimal heat input and near-zero distortion: the weld zone heats and cools instantly, giving a smooth inner weld with dense structure and high strength.
- 02Deep, narrow weldA large penetration depth with a narrow seam, typically free of gas pores, keeps quality stable.
- 033–4× faster than TIGLaser welding speed far exceeds argon-arc TIG welding, multiplying output per shift.
- 04Lower running costNo pre- and post-treatment steps save 30%+ in time and processing cost; non-contact welding means no electrode wear.
Common questions
- Round, square, rectangular and slotted tube. The laser route is preferred where weld appearance and post-weld finishing cost matter.
- Laser welding is 3 to 4 times faster than argon-arc TIG, reaches a weld depth-to-width ratio up to 10:1 with a seam typically free of gas pores, and needs no pre- or post-treatment steps, saving 30%+ in processing time and cost.
- Chemical, pharmaceutical, brewing, petroleum, food, automotive, textile and air conditioning, where welded precision tube replaces seamless.
- Stainless steel and carbon steel coil.
- The YH-90 tops the range at Φ133–Φ219 mm with 1.0–6.0 mm wall.
