Laser Processing

Using focused laser energy to cut, weld, or mark — non-contact, fast, and precise, with the process defined by material, thickness, and the source. The pick is driven by what you're doing (cut/weld/mark), the material and thickness, and edge-quality needs.

Product types

Where engineers draw the lines within laser processing.

Fiber Laser Cutting
Now the standard for sheet metal — fast, efficient, excellent on steel, stainless, aluminum, brass, and copper. Displaced CO2 for most metal cutting.
CO2 Laser
Longer wavelength suited to non-metals (acrylic, wood, some plastics) and thick-section work; largely superseded by fiber on metals.
Laser Welding
Deep, narrow, low-distortion welds at high speed; remote/scanner and hybrid welding for automotive and precision assemblies.
Laser Marking / Engraving
Permanent traceability marks — annealing, etching, engraving — on metals and plastics for serialization and branding.
Tube / 3D & Cladding Systems
Tube lasers cut profiles and tube; 5-axis/3D heads cut formed parts; laser cladding/DED adds and repairs material.

Specs that matter

The numbers to compare first — and which are hard deal-breakers.

Process & material/thickness range
Cut vs weld vs mark and the material/thickness set every other choice.
Deal-breaker
Laser source type & power (kW)
Fiber vs CO2 and wattage set speed and max thickness; more power ≠ always better edge.
Deal-breaker
Cut edge quality & tolerance
Dross, kerf, and edge squareness decide whether a secondary op is needed.
Key
Bed size / axis travels / tube capacity
Defines the largest sheet, part, or tube processed.
Key
Automation (load/unload, nesting, tube feed)
Sheet handling and nesting drive real throughput and lights-out running.
Key
Assist gas type & consumption (N2/O2)
Nitrogen for clean stainless/aluminum edges, oxygen for thick steel speed — a major running cost.
Nice-to-know
Beam quality / focus & cutting head tech
Adaptive optics and head design affect thick-section quality and pierce reliability.

How engineers decide

Rules of thumb behind the common trade-offs.

Fiber or CO2?
Fiber for essentially all metal cutting now — faster, cheaper to run, better on thin and reflective metals (copper, brass). CO2 only where non-metals or specific thick-section characteristics still favor it.
How much power do I need?
Buy for your thickness and throughput, not headline kW. Higher power cuts thick faster, but on thin sheet the machine motion and gas often limit speed, and very high power can hurt edge quality. Match to the real work mix.
Nitrogen or oxygen assist gas?
Nitrogen for oxide-free, weld-ready edges on stainless and aluminum (higher gas cost). Oxygen for faster, cheaper cutting of thick carbon steel, at the cost of an oxidized edge. It's a quality-vs-cost lever per material.
Laser weld vs traditional?
Laser welding for deep, narrow, low-distortion, high-speed welds and precision/automation. Justify it with distortion control and speed; it demands tight fit-up and fixturing that arc processes tolerate more loosely.

What goes wrong — War Stories

Expensive failure modes engineers design around.

⚠ Dross / poor cut edge
Cause: Wrong power/speed/gas for the material and thickness, bad focus
Design around it: Dial in the cut chart, correct assist gas and pressure, verify focus and nozzle condition.
⚠ Reflective-metal instability (Cu/brass)
Cause: Back-reflection and high reflectivity
Design around it: Use fiber with back-reflection protection and correct pierce parameters for reflective metals.
⚠ Weld porosity / cracking
Cause: Contamination, poor fit-up, wrong parameters/shielding
Design around it: Clean joints, tight fixturing/fit-up, correct shielding gas and parameters, pre/post heat where needed.
⚠ Heat distortion on thin parts
Cause: Excess heat input / poor nesting sequence
Design around it: Optimize sequence and cooling, use common-line cutting and micro-joints, manage part support.
