Industrial welding of metal parts and assemblies
We produce MIG, MAG, TIG and spot-welded joints with specialist staff, controlling the assembly and preparing the part for its final finish.

What is industrial welding?
Welding is the process that turns a set of loose parts into a single component. It is also where the final geometry of the assembly is decided: a badly located joint or a poorly planned welding sequence will distort the assembly even if every individual part was correct.
That is why we control the assembly stage: locating the parts, sequencing the joints and checking before final welding. Parts arrive at welding already cut and formed in the same plant, often with locating features prepared at laser cutting.
We have several processes available — MIG, MAG, TIG and spot welding — so we can match the material, the thickness and how demanding the finish needs to be.
Materials and thicknesses for industrial 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.

- Stainless steel joints where the weld will be visible.
- Reinforcements and brackets welded onto formed parts.
- Assemblies that will later be polished or painted.
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
Which welding process do you use?
It depends on the material, thickness and required finish. We work with MIG, MAG, TIG and spot welding and choose what suits each part; TIG is typical when the joint will be visible or the material is stainless.
Do you hold qualified welding procedures?
If your project requires a qualified procedure or welder, say so in your enquiry and we will confirm it explicitly before starting.
Can you polish the weld so it does not show?
Yes. Polishing is done in the same plant and is the usual step when the joint has to be hidden on a visible part.
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.
