Pictured is an example of a weld report. This information, together with the geometry of the assembly and the welds can be exported to welding robot con- trol systems. A new Weld Planning System offered on the well- respected Tribon 4 product from Sweden's Kockums Computer Systems is designed to improve accuracy and reduce costs for planning, welding and assembly operations. The new software module provides the user with precise weld path data, allowing weld joints to be collected into weld sequences, automatically calculat- ing weld parameters and selecting a weld process by automatically extracting the welding information for each stage of production from the assembly definition in the Tribon product information model. The weld joints can be split and analyzed using user configurable rules. Weld parameters include weld size, orientation and welding process. Intelligent algorithms map the weld orientation at a particular stage of assem- bly to the welding position and then selects the appro- priate welding process. The Weld Planning System can also automatically calculate the required weld size. Weld data is accessible through a state-of-the-art browser and navigator technology and can be viewed as a 3-D graphic or in tabular format. Tribon Welding Planning System support the majority of robot systems, and data can be exported in Comma Separated Value format for use in Microsoft Excel and Access. The Weld Planning System is available on Windows NT and can work with Tribon Product Information Models on all available operation system platforms HP-UX, Open VMS, Digital UNIX, Solaris and AIX. Circle 45 on Reader Service Card Kvaerner Mandal Floats Out "Invisible" Patrol Boat Late last year Kvaerner Mandal delivered the proto- type of a new, technologically advanced fast patrol boat which is constructed of anti-magnetic composite mate- rials, designed to provide the vessel a very low radar profile making it virtually invisible. Not only is the hull designed for hard detection, it is also touted as pos- sessing high tolerance of direct impacts. The vessel is part catamaran, part hovercraft, and is designed to be fast and highly maneuverable, while able to carry a heavy payload. Powered by three engines (twin gas turbines with a 500-kW diesel to power the hovercraft system), the 154 ft. (47 m) vessel is designed for a cruising speed of 45 knots in waters as shallow as 3.3 ft. (1 m).
