Abstract: Embodiments of systems and methods for remotely controlling a robotic welding system over a long distance in real time are disclosed. One embodiment is a method that includes tracking movements and control of a mock welding tool operated by a human welder at a local site and generating control parameters corresponding to the movements and control. The control parameters are transmitted from the local site to a robotic welding system at a remote welding site over an ultra-low-latency communication network. The round-trip communication latency over the ultra-low-latency communication network is between 0.5 milliseconds and 20 milliseconds, and a distance between the local site and the remote welding site is at least 50 kilometers. An actual welding operation of the robotic welding system is controlled to form a weld at the remote welding site via remote robotic control of the robotic welding system in response to the control parameters.

Abstract: One embodiment is a combined welder and fume extractor system having a chassis assembly along with a controller and a user interface which are substantially within the chassis assembly to control operation of the system and allow a user to interact with the system. A filter compartment within the chassis assembly has at least one filter to extract welding fume particles from a stream of air forced through the filter compartment. An extractor compartment within the chassis assembly has at least one fan to force the stream of air through the filter compartment. A welding power source compartment within the chassis assembly has welding power electronics circuitry to generate welding output power for a welding operation. A wire feeder compartment within the chassis assembly has a spool of a welding wire electrode and a wire feeder to feed the welding wire electrode from the spool.

Abstract: Embodiments of portable and compact welding fume extractor systems are disclosed. One embodiment of a welding fume extractor system includes a rechargeable battery pack, a controller/user interface configured to control operation of the system and allow a user to interact with the system, a filter housing having at least one filter configured to extract welding fume particles from a stream of air forced through the filter housing, and a fan/blower assembly configured to force the stream of air through the filter housing. The rechargeable battery pack is configured to provide electrical power to at least the fan/blower assembly and the controller/user interface. Furthermore, the system is configured to be worn on the back of a human welder.

Abstract: An ultrasound color flow imaging system is programmed to optimize display images on a display monitor (18) by automatically adjusting a threshold. B-mode data corresponding to valid color data is subjected to statistical analysis including mean and standard deviation (S3). The threshold is computed according to mean plus k (standard deviation), where k preferably is based on a linear regression equation.
