Scalable, Controllable Inductive Arrays for Weld Heating

The navy needs a robust system for weld preheating and post-weld heat treatment in shipyards. This will improve both the throughput of existing welders and remove potentially dangerous electric resistance heater bars which can cause fires upon failure. The new system needs to align with navy welding specifications with regards to thermal uniformity, heating rate, and maximum operating temperatures while also improving survivability in a shipyard environment versus the existing system. To address this need, Physical Sciences Inc. (PSI) proposes the Heating Inductive Array for Thermal Uniform Soaking (HIATUS) system, which will deliver high-accuracy preheat and post-weld heat treatment capabilities while improving the lifetime of system components and providing repairable equipment. Our technology serves as a drop-in replacement for the existing heater bar solution to provide faster heating while maintaining uniformity and preventing overheating.
