Tube & Pipe Laser Cutting
Tube laser cutting machines transform how structural steel connections are fabricated. Instead of hand-marking, band-saw cutting, and manual fitting, a tube laser produces precisely coped, mitered, and slotted tube ends ready for direct welding — from a 3D CAD model in minutes.
Quick Answer
Structural tube lasers handle profiles from 20mm to 400mm diameter (or equivalent RHS/SHS) with wall thickness up to 12mm. Machines like the BLM LT7, Trumpf TruLaser Tube 7000, and Mazak FabriGear offer automated bundle loading, 3D bevel cutting, and direct import from Tekla/SDS-2 structural models.
Profile Types & Capabilities
| Profile | Size Range | Wall Thickness | Power | Typical Speed |
|---|---|---|---|---|
| CHS (round tube) | Ø30–400mm | 2–12mm | 4–10kW | 2–15 m/min |
| RHS (rectangular) | 30×30–300×200mm | 2–10mm | 4–10kW | 2–18 m/min |
| SHS (square) | 30×30–250×250mm | 2–10mm | 4–10kW | 2–18 m/min |
| Channel / L-angle | 50–300mm | 3–15mm | 6–12kW | 1–10 m/min |
| IPE/HEA beams | 80–600mm | Web + flange | 6–15kW | Varies by cut |
Cut Types for Structural Connections
Standard Cuts
- • Square cut: Standard end preparation
- • Miter: Angled cuts for frame joints
- • Coped end: Saddle-shaped cut for tube-to-tube joints
- • Slot/notch: For bolted connections and gussets
- • Holes: Bolt holes drilled during cutting pass
Advanced 3D Cuts
- • Weld prep bevel: V, Y, or K prep at 30–45°
- • Multi-branch joint: Multiple tubes meeting at one node
- • Crown cut: Decorative exposed connections
- • Fish-mouth: Tube end shaped to wrap around another tube
- • Slotted tab: Insert + weld construction
