摘要

Appts. for automatically filled welding a rectangular bottom plate to four vertical side plates comprises a carriage (5) which moves back and forth on the bottom plate; a base plate (6) on the carriage which can rotate horizontally around the vertical axis of the carriage; a welding head (7) mounted on the base plate comprising a welding nozzle (15) rotating around the centre axis which guides weld wire (16) towards the weld line; an X-axis profiling mechanism (17) for moving the nozzle (15) horizontally and at right angles to the weld line so that the extension of the central axis of the nozzle intersects the weld line and a Y-axis profiling mechanism (18) for moving the nozzle along its centre axis to maintain a prescribed gap between tip of wire and weld line; two guide bars (8, 8') on the carriage which can be moved selectively and horizontally towards the side plates to ensure the guiding of carriage (5); a base plate rotating angle detector (9) measuring the rotational angle from a home position; carriage position sensors (10,10') on the front and rear end of the carriage to detect distance of carriage from side plates perpendicular to travelling carriage from side plates perpendicular to travelling direction of carriage; and a weld controller.
