Joining systems

Nothing less than the fastest welding and joining systems in the world

System layout

Profound German Engineering

All over the world, automotive body-in-white manufacturers in particular rely on the top performance of our TURNKEY joining systems. "Mastering the beast." In the conception, in the complete penetration of the system, we generate decided advantages. In every process step, we turn up the performance screw. The plant layout is not about stringing components together. It is about answering many questions: How can I accelerate each individual work step of the cell? How do I safeguard the process and ensure maximum up time? Which processes do I use? And how do I achieve the highest degree of automation with a minimum of personnel? The magic word is engineering. The perfect interplay of experience, know-how, specialists and technology. Add to this our SpeedLine products and we are setting standards in the market.

Efficient assembly production

Focus Automotive

As an OEM or Tier1 supplier, you need to manufacture assemblies quickly and reliably. To this end, we offer reliable  joining processes for all materials used today, and ensure speed, availability and complete traceability. Inour history, we have put more than 2,250 automated joining systems into operation worldwide, some with a project volume of up to € 20 million. Our systems are used to manufacture almost all body-in-white structural parts. We also solve complex joining tasks and have been involved in the topic of e-mobility since 2012. We know the challenges of the automotive industry and see ourselves as a partner who provides  unique solutions to complex challenges. 

Component selection

Best components for the solution


Leading technologies

Automation thrives on fast, reliable robots. We work closely with the leading robot manufacturers. We know what the systems can do and make targeted use of their features and capabilities.


It doesn't get any faster than this

With our SpeedLine, we have closed gaps where standard automated joining systems were not fast enough. Cycle time savings of up to 40 % provide them with maximum efficiency.

Industrial image processing

Everything in view

Checking/measuring/monitoring, 2D position detection, 3D binpicking. With our fully integrated image processing systems, we secure processes in our plants, accelerate them and integrate quality control including complete traceability.

Patch board welding

Ready for electromobility

In modern lightweight construction, with regard to weight savings in electric vehicles, raw blanks made of high-strength steels are increasingly being doubled. This is a demanding process that we have already implemented several times using fast, fully automated patch blank welding.

Industry 4.0

Our own IT

The software and control of our plants is in the hands of our IT specialists. They know Industry 4.0, think automation processes, translate them into codes, create interfaces, coordinate databases...

Completely continuous

Our quality management system (according to DIN EN ISO 9001:2015) is not only implemented throughout the organizaion, we live it daily. Nothing comes into our house, nothing leaves our house, which does not meet our very high quality standards. Quality has several meanings for us. First of all, it concerns the products that we manufacture and the cells that we develop, build and commission for you. It is also about the traceable quality of the products you manufacture with our systems. Only because we think and implement quality from A to Z and beyond our factory gates can we offer you the reliability and longevity of our automated joining systems and give you a competitive edge.

Assembly & Commissioning

TURNKEY to service

We design the cell for you, assemble it,  and test it. If everything runs perfectly, we pack the cell, bring it to the installation site, assemble it, put it into operation, hand it over and continue to provide on going services.

Prototypes & Pre-series

First products

Once the system has been set up and adjusted with all modules and components, we can produce prototypes or high-quality, reproducible pre-series components for you. This gives you the opportunity to coordinate and evaluate parts with customers at an early stage.


Safe transport

We bring our cells quickly and safely to any place in the world. Of course, cost-optimized and with all shipping and customs documents. Our logisticians have a lot of experience, take care and simply know how to do it.


Professional assembly

For us, dismantling the system manufactured by us and packing it cleverly means being prepared for the assembly and installation in detail. Nothing is missing, everything has its place and we know exactly what goes where. Of course, coordinated with your site and infrastructure.


Everything according to plan

The commissioning of your automated joining system is carried out by our specialists who know the system. They carry out the fine tuning and fine adjustment and show you how to operate the system in an optimized way.

Service & Maintenance

Always responsive

We want your cell to run continuously and give you the best possible result. To achieve this, our service technicians are at your side and we can support you with our maintenance packages tailored to your plant.


According to DIN EN ISO 9001 : 2015

Audits are always a welcome opportunity for us to put our processes and quality optimisation measures to the test. We  strive to continuously improve.

The SpeedLine products from LEWA Attendorn


To the point

Our goal was to make spot welding significantly faster and more efficient. Because there were no adequate solutions "off the shelf", we developed them ourselves and packed in as many advantages as possible.


The weight, reduced to 73 kg, combined with the fast servo drive, ensures extreme dynamics and maneuverability.


Our compact, space-saving, easily integrated welding cell full of speed and power.


The SpeedGun welds faster, and the SpeedFrame moves parts with rapid 180-degree turns in under 2 seconds.

Trainings & courses

Transfer of know-how into practice

We want you to be able to use and access the full performance as well as the full potential built into our systems and the components used. With training & education, we show you how to operate the systems safely and efficiently. Our course program is modular and ranges from introductory courses to expert courses and customer-specific training.
