The Comau spot welding machine consists of a welding gun combined with a flange linked directly to a robot that contributes to a light and compact product that can withstand high payload. The automotive industry considers this machine to be a suitable spot welding system for various applications.
Comau teams carried out extensive efforts to regulate the system’s entire components, which led to the evolution of new spot welding gun. It weighs 40% lesser than the earlier models. It features a compact welding gun integrated to an enhanced transformer that can be rotated 90°. The body’s dimensions will therefore be reduced, while the center of gravity will be relocated near the robot's wrist.
The robot's software leverages the fieldbus module and the flexion of the gun arms, thereby eliminating the pneumatic cylinder for balancing the welding gun.
The cooling pipes and cables have been safely enclosed within a protective covering. Its defined layout ensures efficient positioning repeatability. This welding gun represents a new standard, which upon installation serves to be effective as retrofit as well as with all robots.
In addition to the welding gun, advanced robots have been developed. A compact, lightweight robot optimizes the dimensions of every single component including engines in order to maintain the same functional range of the arm.
The cables and pipes across the welding gun have been incorporated within the robot arm for high precision. Following upgrades, the system is free of redundancies. The Comau new spot welding machines’ hinges have been shown by the robot and welding gun.
This welding machine can be mounted on the ceiling. The larger ground area allows greater control over production line, through which operators can have easier re-tooling job with access for maintenance.
Furthermore, welding cells can be developed, transported and deployed worldwide.
