    (2007) Idziak, Eugeniusz; Szyszka, Roman; Siennicki, Andrzej; Turek, Bogdan
    Excavator buckets are fast moving elements. Each bucket is subject for rebuilding before renewed assembly on the excavator. On the robotized welding stand, during rebuilding process, operations of bucket wear parts cutting out, facing by welding, and welding are automatically executed. This is possible since this stand is composed of ROMAT 320 series robot, tilling-rotary positioner witch load capacity 75000 N and welding installation currying following processes: - high-duty MAG-MIG TANDEM method welding, - oxy cutting, - plasma cutting, - facing by core self-guard wires. Reproducible operations execution during bucket rebuilding process with robotized stand caused more efficiency increasing, quality improvement and most noxious and harmful operations elimination for workers health, which were manually by them executed as yet.
