What Is a Fiber Laser Welding Machine?
A fiber laser welding machine uses a high-energy fiber laser beam to melt and join metals with extreme precision. The laser beam is transmitted through an opti
A fiber laser welding machine is an advanced welding system that uses a high-energy fiber laser beam to melt and fuse metals. Unlike traditional welding, fiber laser welding produces a narrow, deep, and clean weld with minimal thermal impact.
Key features:
Extremely high beam density
Small heat-affected zone
Compatible with stainless steel, carbon steel, aluminum, copper, galvanized sheet, titanium, etc.
Suitable for both industrial and workshop use
Today’s handheld systems allow even beginners to achieve professional-quality welding.
How Does a Fiber Laser Welding Machine Work?
Fiber laser welding works through these core steps:
Laser generation
The laser source (Raycus/JPT/Reci) produces a high-intensity laser beam.Beam transmission through fiber cable
The beam travels through a durable fiber-optic cable with very low energy loss.Focusing through a welding head
The welding head uses lenses to focus the beam into a tiny spot to melt metal instantly.Metal fusion
The molten pool forms along the seam, creating a strong welded joint.Cooling and solidification
The weld cools rapidly, resulting in a strong and smooth surface.
Compared to CO₂ or YAG welding, fiber laser welding has higher electro-optical efficiency, lower maintenance, and stronger stability.
Types of Fiber Laser Welding Machines
Fiber laser welding machines are not defined by a single function or a single structure. Instead, each model can combine several features at the same time.
In general, fiber laser welding machines can be categorized from different perspectives:
By function: 4-in-1 and 5-in-1 laser welding machine systems (welding, cleaning, cutting, weld-seam cleaning, etc.)
By mobility: portable handheld laser welding machines and automatic / fixed laser welding machines for mass production
By wobble mode: single-axis wobble or dual-axis wobble laser welding machine
By laser power: 1500W, 2000W, 3000W, and higher industrial power levels
By cooling method: water-cooled or air-cooled laser welding machines
These categories are not independent; instead, they are often combined.
For example, a portable laser welding machine can be 4-in-1 or 5-in-1, can use single-axis or dual-axis wobble laser welder, and can be designed as water-cooled or air cooled laser welding machine, depending on the power level and application.
