Precision joining for demanding components

Laser welding provides a highly controlled method for joining precision components.

At Veldlaser, we develop laser welding processes for applications where weld quality, dimensional stability, accessibility and reproducibility are critical.

The concentrated laser energy creates a localised melt zone, allowing components to be joined with accurately controlled heat input.

Every process is developed around your materials, component geometry, weld requirements and production volume.

Controlled heat input

One of the key advantages of laser welding is the ability to concentrate energy in a small and accurately defined area.

This allows the required weld to be created while limiting thermal influence on the surrounding component.

For precision parts, this can help minimise distortion and preserve dimensional accuracy.

The optimum result depends on material properties, component geometry, joint design, laser parameters and the required weld characteristics.

Spot welding and seam welding

Spot welding

Laser spot welding creates localised welds at precisely defined positions.

It is particularly suitable for small components and assemblies where individual connection points are required.

Seam welding

For continuous joints, the laser follows the defined weld path to create a controlled seam.

Process parameters and component handling are adapted to the required penetration, seam geometry and production requirements.

Heat-conduction welding

Heat-conduction welding uses controlled laser energy to melt the material locally without requiring deep penetration.

At Veldlaser, this process is used for suitable precision components with material thicknesses up to approximately 1 mm.

The relatively controlled heat input makes the process particularly useful where weld appearance, dimensional stability and limited thermal influence are important.

3D laser welding

Precision assemblies are not always flat.

With controlled component positioning, the laser can follow weld geometries on three-dimensional components.

This provides additional design freedom and enables accurate welding of components that require multiple orientations or complex weld paths.

Seam welding

Spot welding

Cross section

Welding with or without filler material

Many laser welding applications can be produced without adding filler material.

Where the material combination, joint geometry or technical requirements make it necessary, filler material can be introduced into the welding process.

Veldlaser maintains a range of filler materials and selects the appropriate welding strategy according to the application.

Weld verification

Measure what happens below the surface

The appearance of a weld alone does not provide complete information about its quality.

Where required, Veldlaser can prepare cross-sections of welded samples to investigate the achieved weld penetration and internal weld geometry.

Our in-house metallurgical capabilities support process development by allowing welding parameters to be tested, measured and optimised.

This helps establish a controlled process before moving into production.

Materials

Material properties have a major influence on laser weldability and process development.

Veldlaser develops welding processes for materials including:

Stainless steel · Titanium · Aluminium · Selected polymers

Other materials and material combinations are assessed according to the specific application.

Factors such as thermal conductivity, reflectivity, alloy composition, joint geometry and required weld properties are considered during process development.

From feasibility to production

A reliable laser welding process starts with the complete application.

We analyse:

Materials → Joint design → Component geometry → Weld requirements → Quality requirements → Production volume

Based on these requirements, we develop and optimise the appropriate welding process.

Veldlaser supports projects from initial feasibility and process development through prototyping and repeatable series production.

Decades of laser welding experience

Laser welding is deeply rooted in Veldlaser’s history.

Our first laser welding activities started in 1987, welding membranes to sensor housings. In 1989, our first dedicated laser welding setup followed.

Since then, Veldlaser has continued to develop its welding technology, including in-house engineered production equipment for laser welding and the introduction of laser welding of plastics in 2018.

Today, this experience is combined with modern laser systems, automated component handling, measurement capabilities and an in-house metallurgical laboratory.
