In considering the use of novel processes for remote applications, particularly if they are to replace highly flexible manual welding techniques, the use of sensing technology and adaptive control must also be considered. (W 258) (2)

Remote application = Aplicação remota

The reliability of the process in industrial applications requires thorough evaluation. (W 149) (3)
