Robotic Welding

Robotic welding began growing quickly and already commands about 20% of industrial robot applications. Many benefits of robotic welding services have proven to make it a technology that helps many OEM manufacturers increase accuracy, repeat-ability and throughput. Robotic Welding increases productivity and reduces manufacturing labor costs that translates to cost savings for our OEM customers.

The major components of arc welding robots are the manipulator, the mechanical unit and the controller which acts as the robot’s “brain”.  The robot may weld from a pre-programmed position, guided by machine vision, or by a combination of the two methods.  Contact us today to assist in your short run and long run applications.
