Laser welding to drawing – contract manufacturing for industrial components
Laser welding in focus
Laser welding is a highly precise thermal joining process in which a focused laser beam locally melts metallic components and permanently joins them. The process enables narrow weld seams, low heat input, and high welding speeds. Especially for precision sheet metal parts, enclosures, assemblies, and series components, laser welding can reduce distortion and significantly reduce the effort required for straightening, grinding, and further post-processing.
DIVIKOM BlechProfis offers laser welding as part of a complete industrial production chain – from cutting and bending to a welded assembly ready for installation.Laser welding

Laser welding to drawing
We manufacture laser-welded components and assemblies according to your drawings, 3D data, and technical specifications.
Depending on the component, we also carry out the upstream manufacturing steps:
- Laser cutting of sheet metal parts
- Bending and forming
- Tube and profile processing
- Preparation and positioning of the components
- Laser welding
- Grinding and further post-processing
- Surface treatment
- Marking and laser marking
- Assembly of complete modules
This allows individual process steps to be coordinated optimally and unnecessary tolerance chains to be avoided.
Laser Welding in Contract Manufacturing
Would you like to have laser-welded components or assemblies manufactured externally? DIVIKOM BlechProfis handles laser welding in contract manufacturing based on drawings, 3D data and your technical specifications.
Depending on the project, we manufacture individual components, small series or recurring series. Laser welding can be commissioned as a single manufacturing step or integrated into a complete process chain.
Typical services in contract manufacturing:
- Laser welding of sheet metal parts and assemblies
- Manufacture according to customer drawing or 3D model
- Processing of steel, stainless steel and aluminium
- Laser cutting and Bending of the individual parts
- Setting up and positioning the components
- Grinding and further post-processing
- Surface treatment and marking
- Assembly of complete modules
This means that, if required, you receive not just a single welding service, but a fully finished assembly from coordinated production.
From drawing to finished assembly
Send us your drawing or CAD data together with the material, quantity, material thickness and the requirements for the weld joint. We check the technical feasibility and adapt the suitable manufacturing strategy to your component.

Advantages of laser welding
Laser welding offers numerous advantages, especially for precise industrial components:
- high welding speed
- narrow and precise weld seams
- low heat input
- low thermal distortion
- high repeat accuracy
- good suitability for automation
- low rework effort
- suitable for batch production
- very good integration into automated manufacturing processes
Whether laser welding is the most economical solution for a specific component depends, among other things, on the material, material thickness, seam geometry, quantity and required weld quality.

Laser welding of steel, stainless steel and aluminium
Depending on the application and technical requirements, different metallic materials can be processed.
Typical materials include:
- Steel
- Stainless steel
- aluminium and aluminium alloys
- nickel alloys
- titanium alloys
- selected copper materials
The suitable process parameters are matched to the material, material thickness, geometry and required seam quality.
Particularly with aluminium and copper, thermal conductivity, reflectivity and surface condition must be taken into account when designing the process.
Precise component preparation for optimum weld seams
Component preparation plays a decisive role in laser welding.
Precise fit and reproducible gap dimensions improve process stability and the quality of the welded joint. That is why, where required, we combine laser welding with upstream processing steps such as Laser cutting, Bending and Tube lasering.
Already during design, interlocking connections, positioning aids or tabs can be provided to align the components precisely and reduce fixture effort.
Laser welding for assemblies and series production
The technology is particularly suitable for components where precision, repeatability and short cycle times are decisive.
Typical applications include:
- Sheet metal housings
- Machine enclosures
- Frames and structures
- Stainless steel components
- Components for mechanical and plant engineering
- Vehicle and transport technology
- Technical assemblies
- Electrical and electronic enclosures
- Components for energy and environmental technology
- Series parts with recurring weld seams
Smaller series and project-related Customised products are also possible depending on component geometry and requirements.
Less distortion and less rework
Due to the concentrated heat input, laser welding often creates a significantly smaller heat-affected zone than conventional welding processes.
This can reduce thermal distortion of the component.
For suitable designs, this means:
- less straightening
- less grinding
- better dimensional accuracy
- shorter post-processing times
- lower manufacturing costs
Whether post-processing can be completely omitted depends on the requirements for surface finish, visual quality and dimensional tolerances.
Quality and process reliability
For industrial applications, requirements for the weld seam can be defined already in the technical documentation.
For the assessment of irregularities in laser beam welded joints, among other things ISO 13919-1 and ISO 13919-2 is relevant.
Depending on the project, requirements may also apply to:
- welding procedure qualification
- process monitoring
- inspection documentation
- non-destructive testing
- Material certificates
- Dimensional inspection reports
- Quality documentation
are to be taken into account.
Please let us know any relevant requirements with your enquiry.
Complete manufacturing instead of individual process steps
A key advantage for our customers lies in combining several manufacturing processes.
Instead of ordering cutting, bending and Welding from different suppliers, we can coordinate complete manufacturing processes:
Laser cutting → bending → positioning → laser welding → finishing → surface treatment → assembly
This reduces interfaces, transport routes and coordination effort.
If required, a permanent marking can then be applied by laser marking or laser engraving .

Frequently asked questions about laser welding
Do you also offer laser welding as subcontract manufacturing?
Yes. We manufacture laser-welded components and assemblies according to customer drawings or 3D data. Depending on the project, upstream manufacturing steps such as laser cutting and bending, as well as post-processing, surface treatment and assembly, can also be handled.
Which components is laser welding suitable for?
Laser welding is particularly suitable for precise sheet metal parts and assemblies with repeatable geometries, tight tolerances and high requirements for dimensional accuracy and weld seam quality.
Which materials can be laser welded?
Typical materials are steel, stainless steel and aluminium. Depending on the application and plant technology, other metallic materials can also be processed.
Is laser welding suitable for small batch quantities?
Yes, depending on component geometry and fixture setup effort. The process often becomes particularly economical for recurring components and series.
Why is component accuracy important in laser welding?
The laser beam acts on a very small area. That is why the gap width, positioning and dimensional accuracy of the components directly influence process stability and weld seam quality.
Can laser welding replace grinding and straightening?
For suitable components, the effort required for straightening and grinding can be significantly reduced. Whether reworking can be eliminated entirely depends on the design and surface requirements.
