The industrial sector of energy and transport is the basis for the infrastructure of a nation, so it is sought the use of applications that avoid additional costs due to defects and failures. In this context, the use of solid-state welding technique such as friction welding in offshore structures is inserted, in contrast to the traditional method of fusion welding repair that can become fragile by hydrogen in submerged environments. The Friction Hydro Pillar Processing (FHPP) consists of drilling a substrate in the cracked region and filling it with a rod submitted to certain conditions of rotation speed and axial force into the cavity generating a metallurgical union between the pieces. An agreement between the company Petrobras and the Federal University of Uberlandia - Brazil has enabled the creation of a Friction Hydro Pillar Processing Machine for field operations able to develop this technique of maintenance of offshore structures in the Laboratory of Technology at Friction and Wear (LTAD). It consists of an automated unit commanded by a dedicated computer and controlled by a Programmable Logic Controller (PLC) Bosch Rexroth L25. This monograph describes the implementation of the HBM U2B® load cell and the Raytek MI infrared temperature sensor, devices that enable the tests performing and the machine monitoring. Routines based on LabView® and also were from the PLC developed looking for automatic detection, communication and settings of this instrumentation.
