What we do
Laser Welding
What is a Laser Welding?
Laser welding, also known as laser beam welding, is a modern process that uses focused laser energy to join metal parts with precision. Compared to traditional welding techniques, it provides a range of advantages:
-
Highly accurate energy delivery, even on delicate or fine structures
-
Minimal heat-affected zones for cleaner results
-
Strong, durable weld seams
-
Non-contact process with no pressure applied to the workpiece
-
Reliable and repeatable quality through precise process control
-
Easy access to difficult-to-reach areas
-
Effective for challenging materials such as aluminum and titanium
Laser Welding Techniques
The right laser welding method depends on the application. Each technique creates a different weld seam, defined by how the welding parameters are set. The most common processes include:
-
Scanner Welding – The laser beam is directed via a rotating mirror, eliminating the need to reposition the workpiece or processing head.
-
Deep Penetration Welding – Uses high laser intensity to create a vaporization effect and plasma, resulting in strong, deep welds. This is the most widely used laser welding method.
-
Micro Welding – Ideal for very small components. Includes spot welding, resistance brazing, and enameled wire welding.
-
Spot Welding – Produces welds under 0.1 mm in diameter with low heat input. The seam is formed from a series of small spots, making it suitable for fine geometries.
-
Seam Welding – A continuous weld created by a steady laser beam, ensuring fast welding speeds for overlap and butt joints.
-
Heat Conduction Welding – Produces flat, shallow welds as the laser intensity stays below the penetration threshold.
-
Powder Deposition Welding – Adds material by fusing metal powder onto a surface with laser energy. Creates smooth layers with minimal heat and is widely used in automotive, energy, and toolmaking industries.

Powder Deposit Welding
Laser Powder Deposition Welding – How It Works
Laser cladding with powder is an additive manufacturing process where metal powder is delivered through a nozzle into the laser beam by a carrier gas, which also acts as a protective shield. The laser energy fuses the powder onto the component’s surface, and by moving the nozzle relative to the workpiece, surfaces, lines, and even complex geometries can be created.
An annular gap nozzle ensures uniform melting, enabling a non-directional process. By applying multiple layers, different thicknesses can be built up, and even complete 3D structures can be produced.
This method delivers pore-free, crack-free coatings with minimal heat input and little dilution of the base material. The result is faster processing with consistently high-quality outcomes.

Precision Laser Hardening
To protect heavily used metal parts and machine components from wear, deformation, and premature failure, laser hardening is a proven solution. ALPHA LASER’s mobile systems precisely scan and harden each workpiece along its contours, without the need for disassembly.
Laser-based surface hardening is one of the fastest methods for creating tough, long-lasting metal parts. The process ensures high wear resistance with minimal distortion, giving you stronger components and greater reliability.
How Laser Hardening Works
A focused laser beam is guided over the surface of the component, rapidly heating only the targeted layer to the hardening temperature. The surrounding material then cools it immediately (self-quenching), creating a tough, hardened surface while the core remains unchanged.
-
Adjustable track widths (1–100 mm) and penetration depths up to 2 mm, depending on material
-
Produces a hardened outer layer with a strong, resilient core
-
Minimal distortion thanks to localized heating
Advantages of Laser Hardening
-
Precisely hardens only the zones exposed to wear, following the exact contour
-
Produces a tough, hardened surface while keeping the core strong and resilient
-
Self-quenching effect enables rapid cooling with no need for external cooling media
-
Low-distortion process with little to no rework required
-
Hardening possible on cutting edges, guideways, grooves, and free-form surfaces
-
Can be performed in open atmospheric conditions, with or without shielding gas
