PEMA VISION ROBOT SYSTEM
MORE POWER TO PANEL PRODUCTION
F
or shipyards, maintaining a competitive edge requires efficient
production. Improvements in cost-effectiveness usually call for
more automation. With its high arc time ratio (over 80 %) and utility ratio (100%), the user-friendly PEMA VRWP robot portals significantly raise the productivity of panel production lines. A VRWP
portal consists of a sturdy robot welding gantry with 3 external robot axis, 6 axis welding robot, welding equipment, and patented
Vision System based revolutionary robot programming.
Patented machine Vision programming is a unique on-line
programming method that features a short programming time
(typically less than 30 minutes for one 8-hour shift welding work)
and thus there are no off-line programming problems. During a
single shift work, one Vision robot makes appr. 160 metres in
welds; horizontal and vertical ones. These systems can be easily
supported by qualified welders and the programme has high utility
ratio due to working always with a real work piece, not a model.
Remarkable cost savings have been achieved by using this system
which also applies superior and stable welding quality itself.
Customers are typically shipyards which build highly demanding cruise liners or naval ships or multipurpose ships. Fincantieri,
Navantia and STX Europe are among of the satisfied users at the
moment. Applications with multiple robots at same portal have
been supplied also to further improve the productivity. ■
The Vision robot system is best suited for the welding of panels that
are largely similar, yet still individualised. Pictured is one of VRWP8000/1 Vision robot portals at STX Europe, Turku Shipyard.
