KUKA spot welding technology from single robots to complete spot welding systems
In spot or resistance welding, high mechanical pressure is applied to a relatively small area and a large amount of energy is supplied in the form of an electric current. In the process, two electrodes press sheets of metal together and convert the welding current into heat at the metals contact surface, as a result of which a permanent fixed joint is created between the two metal sheets.
KUKA offers cost-effective and high-quality spot welding solutions for resistance spot welding, even for customer specific weld requirements. Our products short delivery times enable individual solutions for the automation of spot welding - from welding robot arms with high payloads and optional additional axis to complete spot welding lines with perfectly matched components

KUKA.RoboSpin: Weld aluminium as easily and as quickly as steel
With conventional resistance spot welding of aluminium components, the welding process takes place at a standstill. In this process, the copper caps often stick to the sheets and therefore have to be milled frequently and thus replaced more often.
KUKA has therefore created a solution
that is tailored precisely address to this problem. The robot moves to the next welding point during the welding process. The electrodes therefore do not remain rigid, but rotate
through a certain angle on the spot to be welded. Robospin enables spot welding of aluminium with low wear and better quality.
The robot rotates the servo gun during welding and thus significantly increases the service life of the electrode caps
Welding aluminum? No problem! Score high now in production for electromobility.
Aluminium plays an important role in e-mobility because of its ideal combination of lightness and strength. In welding and joining processes, the material aluminum can withstand high demands. With comprehensive process know-how and the right products, KUKA prepares you for the technological transformation towards e-mobility. The example of the battery box shows how the use of robots enables the production of aluminum components at a high quality level in a short time.
