Interactive 3D graphics-based simulation tool robot welds fuel tanks

摘要

Faced with the challenge of developing a welding process for Caterpillar's D6 through the D10 Track-Type Tractor (bulldozer) fuel tanks, steel fabricator Wrayco Industries, Inc. collaborated with ABB's Welding Systems Division, to design and build a cell to facilitate the process. The fuel tanks, with capacities ranging from 100 to 300 gallons, have numerous exterior brackets and fittings requiring leak proof seam welds. The largest tank, which weighs 1,000 lb. dry, has seams in excess of 8 feet. By assembling and robotically welding the tanks in a 40 × 120 ft. bay, Wrayco (Stow, OH) eliminated difficult and time-consuming part positioning and handling associated with manual welding. Producing the tanks in one bay eliminates movement to various weld booths throughout the shop. This in turn simplifies the process, saves time, reduces cost, and minimizes handling and subsequent part damage.
