PEMA has commenced the delivery of a portal-type, machine-vision aided robot heavy welding station for the Chinese Jiangsu Rainbow Heavy Industries Co. The station will be used in welding of tack-welded end and side-plates of MacGregor hatch covers for cargo ships.

The scope of the delivery is a complete PEMA VRWP-5500/1 vision robot welding portal including a Yaskawa-Motoman MH6 welding robot with a DX100 controller and a Lincoln Electric PowerWave 455M MAG welding power source. The VRWP portal consists of a sturdy robot welding gantry with three external robot axis, six-axis welding robot and the patented Vision System robot programming. The delivery also includes a PEMA fume extraction system, PEMA rails and gear racks, required welding programs, and an installation, start-up, training and service package.
