Abstract: Friction stir welding equipment control force spindle for mounting in an orbital head housing uses a coaxial sensor to measure downforce. Simultaneously, an axial electrical actuator is controlled to dynamically correct the axial tool position during the welding, by a direct axial force system control, in order to maintain controlled downforce according to parameters previously set, based on numerical control. The equipment also sets up, monitors and controls spindle rotation speed, welding speed, acceleration speed and downforce using for example closed loop control functions. A laser system may scan the backing surface before welding and correct original tool path, in order to get an offset tool path. A precision alarm system may provide safe welding while preventing the tool from colliding with the backing surface.

Abstract: The present invention relates to a system and method of controlling a linear compressor (10), which is capable of fine-tuning the compressor when necessary, throughout the operating period of the compressor, so that said compressor operates at maximum capacity, wherein the piston (1) achieves a maximum displacement amplitude, closely approaching the cylinder head (2) without colliding with it. The system and the method according to the invention are also intended to control the operation of the linear compressor throughout its operating period, also seeking to maximize its performance and to reduce or optimize its power consumption. According to the present invention, the fine-tuning and control of the operation of the linear compressor are carried out by means of the combination of a technique for controlling a compressor without a sensor, and a technique for controlling the compressor with the aid of a sensor.

Abstract: A method of detecting the occurrence of impact or collision between a cylinder (2) and piston (1) driven by a linear motor of a gas compressor includes the steps of i) obtainment of a reference signal (Sr) associated to an electrical output of the linear motor before the piston attains the upper dead center; ii) obtainment of a detection signal (Sd) associated to said electrical output of the linear motor after the piston attains the upper dead center; iii) comparison between the reference signal (Sr) and the detection signal (Sd); and iv) record of occurrence of impact when the result of comparison of step iii indicates that the detection signal (Sd) presents a variation deriving from impact between the cylinder (2) and the piston (1), considering a pre-established tolerance. Also disclosed is an electronic detector device capable of executing the methodology described above. A gas compressor (100) and a control system including the above-mentioned detector are also disclosed.

Abstract: Friction stir welding (FSW) processes, systems and the resulting friction stir welded components are disclosed whereby first and second workpieces are welded to one another using a first workpiece having mutually orthogonal structural components and a junction region therebetween which defines a bearing surface of predetermined geometry. A shoulder of a FSW tool may be brought into bearing contact with the bearing surface so that a pin extending from the shoulder of the FSW tool may be advanced into and through the one structural component of the first workpiece at an angle relative thereto so as to thereby form a friction stir weld region between the first and second workpieces. Some preferred embodiments will provide a bearing surface which defines an arcuately concave geometry, in which case the shoulder of the FSW tool defines an arcuately convex geometry conformably mateable with the bearing surface.
