AN AUTOMATED WELDING SYSTEM FOR WELDING OF IRREGULARLY SHAPED BIFURCATE COMPONENTS

摘要

This invention relates to an automated welding system for bifurcate welding, comprising a front end motor (4) a rear end motor (8); an irregular shaped bifurcate object (27) held in a weld head assembly for welding to a third leg, the third leg being placed in a movable clamping plate (6); a TIG torch assembly (2), and a MIG torch assembly(3) rotatably mounted on the machine carriage (1), the torch assemblies (2, 3) being free in a single direction; the TIG torch assembly (2) is enabled to first move forward to carry-out the root welding while both the bifurcate (27) and the third leg is rotated respectively by the front end and rear end motors (4, 8) and return to home position, the MIG torch assembly (3) being activated upon return of the TIG torch assembly (2) to home position and complete the weld joint, wherein the weld head assembly is configured to have horizontal and vertical holding plates (25, 31) to hold the object (27), the clamping plate (6) to hold the third leg, one each vertical and horizontal adjustment means (29, 28), a side plate (1), and a plurality of nuts, bolts, washers (2, 3, 5, 7, 8, 10-14), and at least one each holding screw and locating pin (10,9).
