Laser sensing systems for
welding automation
Servo-Robot is a specialist in laser sensing systems for welding automation.
The company’s systems are used in the transmission pipe industry to improve
weld quality and increase process speed.
Servo-Robot laser sensors can
be applied in several stages
of pipe and tube production
including seam tracking of interior
and exterior welds, inspection of
seam or weld bead geometry and
monitoring of the pipe diameter.
The systems consist of one or
more laser-cameras with a simple
PC-based interface to perform
initial setup and to provide data
logging and trending capability.
The Auto-Trac system is designed for seam tracking with fixed automation
systems typically found on spiral pipe mills. The Robo-Trac system offers seam
tracking for articulated welding robots. The systems support many types of
welding, including Submerged arc welding, gas tungsten arc welding, and gas
metal arc welding. There are also systems for laser welding applications. Servo-
Robot systems have been successfully used in the production of pressure
tanks, spiral pipe mills and other applications that require high quality welds.
The company’s range of products includes systems for seam tracking, seam
finding, weld inspection and laser welding modules.
