Laser welding of metal parts
We weld with a laser to produce clean, fast joints with lower heat input and reduced distortion on thin or visible parts.
Clean joints · Low distortion
What is laser welding?
Laser welding concentrates energy into a very small area. That has two practical consequences: the bead is narrow and clean, and the heat the surrounding material receives is far lower than with conventional processes.
It solves a recurring problem with thin sheet and visible parts: thermal distortion. A thin part welded with too much heat input bows and loses flatness, and correcting it afterwards costs time and is not always possible. With a laser, the part stays much more stable.
It is the process of choice when the joint has to be visible with a clean finish, or when the part is too thin or too dimensionally demanding for conventional welding.
Materials and thicknesses for laser welding
Metals and sheet thicknesses we work with as standard. If your industrial project needs a material that is not in the table, say so in your enquiry and our engineering office will confirm whether we can handle it.
This service works with the same materials and thicknesses as the rest of the plant. The full table is on the Sheet metal laser cutting page.
CAD file formats accepted for quoting
- DXF
- DWG
- STEP / STP
- STL
- IGS / IGES
- PNG
- JPG
With DXF, DWG or STEP we work straight from your file geometry: no need to redraw the part, and the quote comes back sooner.
We do more than check the drawing: we advise you on nesting (how the sheet is used) so you get the lowest possible price per part before anything is cut.
How our engineering office works

Confidential handling. Your drawings are only used to prepare the technical assessment and are not shared with third parties. If you need a signed non-disclosure agreement, send it over.
Technical capabilities for laser welding
| Characteristics | Narrow bead, reduced heat input and less distortion |
|---|---|
| Suited to | Thin sheet, visible parts and dimensionally demanding assemblies |
| Finish | A clean joint that needs less rework afterwards |
Applications and types of custom metal parts
- Visible joints where the appearance of the bead matters.
- Thin sheet parts sensitive to thermal distortion.
- Assemblies that must stay flat after welding.
- Joints that need little rework before polishing.
Sectors we manufacture for
We manufacture for industrial companies across very different sectors. These are some of the most common ones, but not the only ones: if yours is not listed, tell us about the part and we will confirm whether we can make it.
- Automotive
- Food industry (stainless steel)
- Agricultural machinery
- Construction
- Steel structures
- Energy
- Street furniture
Why work with Catà Germans
- Every process under one roof
- Cutting, forming, machining, welding and finishing in the same plant. We handle the whole logistics side so you receive the parts palletised and protected at your own factory, anywhere in Catalonia and the surrounding area, on the agreed lead time.
- In-house engineering office
- We review the drawing before manufacturing and prepare production from CAD/CAM. If something does not add up, we ask you instead of interpreting it ourselves. And if what you have is a sketch or a question, we will help with that too: advice is part of the service.
- From drawing to finished product
- Some finishes, such as painting or zinc plating, are done with specialist workshops. We handle the coordination and deliver with our own fleet: a single order and a part ready to fit.
- Raw material in stock
- We keep sheet and tube permanently in stock, so many standard jobs can start without waiting for material.
- Over 65 years of the trade
- A family business founded in 1958, specialised in industrial subcontracting of metal parts. You deal directly with the people who make the part.
Frequently asked questions
When is laser welding better than MIG or TIG?
Mainly when distortion is the problem — thin sheet, long parts, tight dimensions — or when the joint is visible and a clean bead matters. For thicker material and structural joints, conventional processes remain the reference.
What thicknesses can you laser weld?
It depends on the material and thickness of the part. Send us the drawing and we will confirm when we reply.
Does the joint need reworking afterwards?
Less than with a conventional process, but it depends on the finish the part needs. If it has to be completely invisible, polishing is still the final step.
Which file formats do you accept?
We accept PDF, DXF, DWG, STEP/STP, STL, IGS/IGES and also PNG or JPG images. If you do not have a final drawing yet, send us a dimensioned sketch and we will review it all the same.
Do you make one-off parts or only production runs?
We handle one-off parts and prototypes as well as small, medium and large batches and repeat production. You can specify this in the quote request.
How quickly do you reply to an enquiry?
We send the technical response as soon as possible once we have the drawing and the part details.
Do you offer painting, zinc plating or other surface finishes?
You can include them in the order. These finishes are carried out with specialist workshops we work with regularly, but we handle the coordination and the transport: you place a single order and receive the finished part.
Can I combine several processes in one part?
Yes — that is the normal way we work. A part can go through laser cutting, bending, welding and finishing inside the same plant, under a single order and a single point of contact.
