Abstract: An apparatus includes a platform, controller, and first and second extension members, brush tool members, and brush tools. The platform has a length orthogonal to and greater than its width. The first and second extension members are movably coupled to the platform and their longitudinal axes are parallel to the length of the platform. The first and second brush tool members are coupled to and extend along the longitudinal axes of the first and second extension members respectively. The first and second brush tools are coupled to and extend along the longitudinal axes of the first and second brush tool members respectively. The controller moves the first extension member towards the front end of the platform, retracts the first extension member towards the back end of the platform, and at a second time after the first time, moves the second extension member towards the front end of the platform.

Abstract: A mechanical system for automatic guiding of one or more torches of a welding unit in a groove delimited by chamfered end surfaces of two metal parts to be welded together, including a main carriage moving along a stationary guide relatively parallel to the groove, a secondary carriage that is connected to the main carriage by a hinged linking assembly and that includes a torch supporting unit and a guiding device including bearing members in contact with the surfaces of the metal parts bordering the groove and sensing members that enter the groove. The hinged linking assembly includes three pivoting axis.

Abstract: In a method for controlling pulse arc welding where an arc is created between a wire and a base material, a pulse waveform different from the pulse waveform for steady-state welding is outputted when a predetermined time has passed since short-circuit welding control was started at arc start, and after a sufficiently large melt pool is formed, the pulse waveform for the steady-state welding is outputted. This reduces the generation of spatters after an arc is created and until the arc is stabilized.

Abstract: The invention relates to a method for permanently interconnecting components from a heat-meltable metal material, using a robot-controlled welding unit for carrying out a hybrid welding process. According to the method, a high performance metal active gas welding process (high performance MAG) is carried out. A component (8) carrying out the high performance MAG welding process is carried along by the robot-controlled welding unit (2) to carry out the hybrid welding process, the GSMAW torch (3) which contributes to the hybrid welding process being guided so as to be dragged by the welding unit.

Abstract: A method for joining together at least two sheets with a tool controlled by an industrial robot and including a first arm and a second arm that are mutually movable in relation to each other. An actual position of the sheets is detected by bringing one of the arms to sense the actual position of the sheets. The distance between an ideal position and the actual position is calculated and the actual position of the tool is moved the calculated distance, whereafter the sheets are joined together.

Abstract: A positioning device (13) for producing a light signal (32) to position a robot tool (2) relative to a workpiece (14) is provided. The positioning device (13) comprises a frame (16) and a pair of light sources (22, 24) mounted at the free end of the frame and arranged to direct a pair of light beams (28, 30) therefrom in converging directions which intersect with each other and provide a light signal (32) at a predetermined distance from the free end of the frame (16). The positioning device (13) can include two pairs of light sources to generate two pairs of intersecting light beams (28, 30; 29, 31). The two pairs of light sources can be arranged so that the two pairs of light beams (28, 30; 29, 31) are located substantially 90 degrees apart.

Abstract: A housing for a proximity sensor is resistant to harsh environmental effects, such as scorching particles due to sputtering in a welding environment. The sensor housing is formed of a material having a high thermal conductivity, such as copper or an alloy thereof. As a result, the housing is able to rapidly dissipate heat and, in turn, mitigate weld slag build-up so as to improve the efficacy of the sensor.
