Cell management activities concern the communications between the welding system and the external production environment. The control should be able to actuate component delivery and discharge systems provide job status and quality information. The combination of computer control and modular mechanical design offers an alternative to the normal robotic approach. Remote-control Slave and Automatic Systems Remote-control welding devices are used in particularly hazardous environments. They may take the form of a master-slave manipulator or a fully automatic system with remote monitoring. Master-slave manipulators MSM This type of system involves the use of a multi-axis positioner which is positioned and controlled by a remote manual operator. Figure Remote-controlled master-slave manipulator msm arm. Courtesy of ANSA. 322 Advanced Welding Processes These devices have been used in the nuclear industry for the manipulation of radioactive components and in hyperbaric applications for positioning components or welding inside a high-pressure chamber. These systems are usually specially built to meet the specific application requirements although some general-purpose arms are available t these are not normally designed for welding applications and the repeatability positional accuracy and load carrying performance must be evaluated carefully. Figure shows a typical MSM arm welding systems of this type have been specially developed for nuclear applications. Fully automatic remote welding systems The use of fully automatic systems for remote welding applications reduces the possibility of manual error and should improve 300 metres power and control Shipboard Surface control station Interface Umbilical Power source Control system Dry Habitat Figure Automatic .
