A QCW (Quasi-Continuous Wave) fibre laser is a specialised laser that operates in two distinct modes: pulsed mode and continuous wave (CW) mode.

Unlike standard pulsed lasers, QCW lasers emit long pulses (ranging from microseconds to milliseconds) with very high peak power. They achieve a high duty cycle (often up to 10%), meaning the laser can remain "on" for a significant portion of the cycle. When needed, they can also switch to a pure CW mode for steady, uninterrupted energy delivery. 

Key Benefits

• High Peak Power: Delivers peak power up to 10 times greater than its average power.
• Minimal Heat Input: Long pulses with rapid cooling intervals prevent material distortion and burning.
• Small Heat-Affected Zone (HAZ): Focuses energy precisely, preserving the structural integrity of surrounding areas.
• Cost-Effective Alternative: Replaces expensive, high-maintenance legacy flashlamp-pumped Nd: YAG lasers.
• Exceptional Wall-Plug Efficiency: Converts electricity to laser light with over 30% efficiency, lowering energy bills.
• Maintenance-Free Operation: Utilises a completely sealed, rugged fibre design with no mirrors to align.
• Dual-Mode Flexibility: Switches seamlessly between high-energy pulsing and continuous wave processing.
• Compact Footprint: Requires significantly less floor space than traditional gas or solid-state lasers.

Common Applications

• Mold shop welding repairs: Perfect for heavy items that can be wheeled to the welder or the welder wheeled to the job.
• Precision Welding: Ideal for medical devices, battery tabs, and electronic components.
• Fine Cutting: Cleanly cuts highly reflective metals like copper, brass, and aluminium.
• Micro-Drilling: Creates precise, microscopic holes in aerospace and automotive parts. 

What is a QCW fibre laser and why would I need one?

A QCW (Quasi-Continuous Wave) fibre laser combines the precision of a pulsed laser with the higher power output of a continuous wave laser. It delivers very short, high-energy pulses that produce deep, accurate welds while minimising heat build-up in the surrounding material.

This makes QCW fibre lasers ideal for applications where precision, strength and a clean finish are essential.

Why choose a QCW fibre laser?

QCW fibre lasers offer several advantages over traditional laser welding technologies:

• Precision welding with excellent control over heat input.
• Minimal distortion, reducing the risk of warping delicate or precision components.
• Deep weld penetration for strong, high-quality joints.
• Low maintenance, as there are no flash lamps to replace.
• High electrical efficiency, helping to reduce running costs.
• Long service life with reliable fibre laser technology.
• Suitable for a wide range of metals, including stainless steel, tool steel, aluminium, titanium, nickel alloys and copper alloys.

Is a QCW fibre laser right for my application?

A QCW fibre laser is an excellent choice if you need to:

• Repair expensive tooling or moulds.
• Weld precision engineering components.
• Minimise post-weld finishing.
• Reduce heat damage to surrounding materials.
• Improve productivity with faster, repeatable welds.
• Replace an ageing YAG laser welding system with modern fibre laser technology.

For larger workpieces or components that are difficult to position, systems such as the GVUK Signature 300W Articulated QCW Fibre Laser Welder provide the added benefit of a flexible articulated arm, allowing the laser head to be brought to the job rather than moving the workpiece.
