Sensors for feedback controls in solid state resistance welding operations

PDF Version Also Available for Download.

Description

The Savannah River Site (SRS) has a 40-plus year history of producing and processing tritium primarily for use in nuclear weapons. This gas is stored at high pressures in reservoirs that are manufactured and sealed through the use of special resistance welding processes. There is an interest in maintaining the quality and consistency of these welds to avoid leaks in the reservoirs. The reasons for this are the limited supply and high cost of producing tritium, the necessity of assuring nuclear safety and to promote weapon system reliability. Precisely machined 304-L and 316 stainless steel components are the materials used ... continued below

Description

The Savannah River Site (SRS) has a 40-plus year history of producing and processing tritium primarily for use in nuclear weapons. This gas is stored at high pressures in reservoirs that are manufactured and sealed through the use of special resistance welding processes. There is an interest in maintaining the quality and consistency of these welds to avoid leaks in the reservoirs. The reasons for this are the limited supply and high cost of producing tritium, the necessity of assuring nuclear safety and to promote weapon system reliability. Precisely machined 304-L and 316 stainless steel components are the materials used in the fabrication of the reservoir. This presentation will include a survey of sensors for use in resistance welding processes. The results of the application of the analog laser position sensor will be presented along with data indicating how the displacement parameter defines the weld process. Opportunities to close the control loop by taking sensor data into the weld controller will be discussed.
