A metal inert gas arc welding process in which a multi-wire welding torch (40) is mechanized along a path to execute a predetermined weld seam on a workpiece (32, 100a, 100b, 101a, 101b), and in which a first arc (51) is generated between a first consumable wire electrode (50) and the workpiece, and a second arc (61) is generated between a second consumable wire electrode (60) and the workpiece to transfer wire electrode material into a weld pool, wherein the first wire electrode (50) is supplied by a first power source (4) and the second wire electrode (60) by a second power source (6), and at least a third wire (70) is fed directly into the weld pool, wherein the first and second wire electrodes (50, 60) and the third wire (70) are guided in the multi-wire welding torch (40) such that the wires exiting the multi-wire welding torch (40) (50, 60,70) essentially lie in a common plane (GE) and that in the common plane the first wire electrode (50) and the second wire electrode (60) form an angle of equal magnitude with opposite signs to the third wire (70), characterized in that, during the execution of the metal inert gas arc welding process, starting from a predetermined direction of movement of the multi-wire welding torch (40) to the path line, the multi-wire welding torch (40) is moved backwards on the path line without rotation of the multi-wire welding torch (40) to perform a reversal of movement, and with the beginning of the backward movement of the multi-wire welding torch (40), the third wire (70) is initially not fed into the weld pool, and thereafter, in a transition phase, a current source (5) of the third wire (70) is supplied starting from a predetermined initial operating value of at least one process parameter current,Voltage and feed rate are controlled to a predetermined steady-state operating value of at least one process parameter.

The application relates to a field boundary recognition method and device based on agricultural machinery trajectories, equipment and a medium. The method comprises the following steps: obtaining dimensional information contained in a plurality of agricultural machinery trajectory points; obtaining a plurality of work path line segments based on the dimensional information; rotating the work path line segments to a work coordinate system according to a work main heading angle, and extracting a one-dimensional point column formed by the work path line segments in the direction of a target coordinate axis of the work coordinate system; performing autocorrelation analysis on a density distribution histogram constructed by the one-dimensional point column to determine an equivalent width estimation value; clustering the work path line segments based on the work path line segments and the equivalent width estimation value to obtain a plurality of work field region points; constructing a triangulation for each work field region point, eliminating triangles with a circumscribed circle radius greater than a preset threshold, and forming a target field boundary by using the remaining triangles. The entire process of the application is fully automated, the field boundary can be accurately fitted without manual intervention, and the application is suitable for complex field contours with convex and concave shapes.
