Robots perform production welding for
bridges
Bridge builder Mabey and Johnson has ordered an IRB 2400L welding robot to add to six welding robots already in use at its Lydney, Glos plant.

Controller directs four-robot coordination
Fifth generation robot controller represents the biggest technological step forward since the introduction of the first generation series in 1974, says robot builder.
Six modular ABB robots perform welding of bridge components, each robot being mounted on a travelling column and organised into paired cells.
Two cells are dedicated to panel production, two to chords and two to bridge decking.
The IRB 2400L will be a 'floating' cell to back up the three existing cells when demand exceeds any one individual cell's capacity, or standing in for any robot taken off-line for maintenance.
The cells operate 24h/day, seven days/week.
The Bullseye feature allows the robot to check its own tool centre point.
The advanced weld control features 'through-the-arc' seam tracking.
It follows weld joints by sampling the welding current and voltage signals synchronised with a robotic weave pattern.
It also provides horizontal and vertical correction signals to the robot controller to assure a consistent fill of the weld joint. Request free introductory details about products from ABB Robotics ...
