ROBOTIC WELDING SYSTEM

Abstract: a robotic welding system comprises a supporting arm for attaching to a repositionable support structure, the supporting arm comprising a first mounting portion connectable to the repositionable support structure, and a second mounting portion rotatably coupled to the first mounting portion. a yaw rotary actuator rotates the second mounting portion about a yaw axis. a welding arm comprises a third mounting portion rotatably coupled to the second mounting portion of the supporting arm. a pitch rotary actuator rotates the third mounting portion about a pitch axis generally perpendicular to the yaw axis. a roll rotary actuator rotates a torch holding portion having a torch mount at an end thereof configured for mounting a welding torch about a roll axis generally perpendicular to the pitch axis. a controller is operably coupled to the actuators to cause the welding torch to execute a welding pattern.
