A customer required a large positioning system rated to 20,000 lbs max payload for holding, tilting and turning heavy centrifuge parts during a fabrication process, along with a high deposition welding process, all fully integrated. They needed costs to be minimized due to budget cutbacks, but needed the equipment for production demands. An economical, customized, centrifuge welding and handling system was required to meet these criteria and the customer knew that LJ was the best suited company in the industry to meet this challenge.
The customer was using old positioning equipment with a limited range of motion, that could not meet their fabrication needs because they could not position the centrifuge cover workpiece in a way that was required. As a result, they were forced to handle parts unproductively, with multiple extra steps in the process. Furthermore, they were unable to make use of high deposition processes like submerged arc welding (SAW) to increase their welding efficiency.
The customer needed a manufacturer that could engineer a system and provide 3D animations to fully illustrate the proposed process. The 3D animations included a welding torch reach study and simulation to ensure that the overall system would accommodate all required handling and welding sequences. It was discovered during the engineering phase that some crucial design features needed to be included to ensure the fixture, welding positioner and welding system would work the way the customer needed, and revisions to the design were succesfully implemented. Full engineering models were provided to ensure the customer got exactly what they needed, and once drawings were signed off by the customer, LJ wasted no time and began manufacturing of the custom welding cell.
Specifically, the system included:
