Integrator For Industrial Robots

Yaskawa Motoman is the world leader in arc welding robotics with industry firsts such as patented multiple robot control and MA-series robots.  Integrated through-the-arm cabling improves weld accuracy, improves torch access and reduces downtime.  Motoman backs the performance of the MA-series robots with the industry's first two-year torch cable warranty.  This patented torch cable design was key to the success of the EA-series robots and is not available from other companies. Motoman also was the first with an extended reach (>3.0 m) robot for arc welding (HP50-20) and has an extended reach MA-series robot (MA3100).

Yaskawa Motoman is extending the success of these arc welding arms with the introduction of the first 7-axis arc welding robot. The flexibility of the VA1400 model can be used to reduce floorspace and achieve higher robot density for increased production. The unique "elbow" axis of the arm also allows the robot to reach around tall parts or reach into boxy parts.

Spot welding is a resistance welding process that uses large electrical current to join two or more sheets of metal in a single location. Spot welding technology has evolved through its extensive use in automobile manufacturing using articulated robots. Kawasaki is pushing the envelope by developing spot welding automation that offers through arm cable routing, reduces cycle time, allows greater control, and reduces cost.

Kawasaki robots use an additional servo motor with a high resolution encoder to precisely control the motion of a spot welding gun. The Kawasaki spot welding software accurately controls the position, acceleration, and force of the gun. The position control and force calibration allow for different thicknesses and types of material to be welded. Kawasaki's advanced servo gun software optimizes the gun motion profile which results in an average cycle time reduction of 20%.

Kawasaki's experience with industry-leading spot welding technology can help you increase product quality, reduce production cycle time, or design and build a custom turnkey spot welding solution.
