Consisting of bleeding edge technology, honed for efficiency

CoWelder’s core components are made up of excellent technology. The result is a welding solution that becomes more than the sum of it’s parts. Fantastic welding capabilities mixed with the agility and safety of the collaborative robot simply lifts all aspect of welding production.

Uncompromised welding

Top-of-the-line Migatronic welding machines are the core of CoWelder. Choose MIG/MAG or TIG welding proces.

Innovative robot technology

The robot arm is the innovative collaborative robot from one of the world’s leading developers and manufacturers – Universal Robots.

Software assisted

Clever software functions lets you tackle the hardest challenges and speed up your welding workflow.

A great workstation

Best-in-class welding and fixture table can be included with CoWelder solutions.


Increase your arc time

Every minute your arc is off is unproductive. CoWelder will get the job done faster than any manual welder could ever do.

It will give your welding production more arc time. Every movement is fine-tuned towards spending just the needed time on each weld.

Getting the angle right

CoWelder utilises 6 axes to move around the workpiece during welding. This agility and reach allows the robot to keep welding where a human arm with only 3 axes would need to stop to reposition.

No movements wasted

CoWelder will not make any stop and start in the middle of a weld. It will skip the detours and only make the most necessary torch movements. It will finish multiple workpieces without stopping.

Inhuman reach

CoWelder can reach over double that of humans. It can keep welding for long stretches without reducing accuracy or having unnescessary start/stop. 

Do more workpieces at a time

If your workpiece is small, place more workpieces in the reach of CoWelder and save valuable time. Combined with the Offset-function, arc time/hour will increase significantly.


Scale your production as needed

Weld small or large batches and often or rarely recurring tasks. Upscale and downscale quickly when necessary. Simply adjust the production to your orders.

CoWelder brings a new definition to the word flexibility in modern day industrial production. It is so easy to switch over the production that it pays off to automate welding of simple workpieces no matter the quantity or frequency. Be able to weld workpieces for specific orders at peak points or produce for stock at low volume times.

First time a new order is received

Recieve an order.
Build fixture to fixate component(s).
Make a program for the workpiece.
Refine welding settings and save job.
Produce and deliver order.
Store fixture for later use.

Any time there is a repeat order

Recieve order.
Retrieve fixture and welding job.
Produce and deliver order.


Perfect welds every time

Increase repeatability in simple welded workpieces by automating recurring welding jobs. All components are welded in the same way every time independent of the frequency and the operator. This can reduce your error rate significantly. Be able to deliver unform welds in a high quality and improve your product.

Leave the dull stuff to the robot

Minimise monotonously repeated work and let the cobot take over the dull routine jobs. Utilise the know-how of your skilled welders for the complicated tasks instead.

Optimises work processes in close collaboration with welders.
Prevent repetitive strain injury (RSI)
Reduce exposure to UV/IR radiation and fumes.
Reduce sick days.
Increase job satisfaction.


“I worked as a welder for many years and at some point, my job got dull. It was too much of the same. That is why it was an interesting challenge for me to be included in the CoWelder project. It is safe to say that working with the CoWelder, I rediscovered how fun work can be.”
