Publication number: 20230274407Abstract: Systems and methods are provided herein useful to analyzing weld quality. In some embodiments, the systems and methods identify or predict weld characteristics such as surface discontinuities and/or subsurface discontinuities based on surface topology data and/or welding process parameters. The systems and methods described herein leverage machine learning algorithms to identify relationships between historic weld characteristics and historic pre-weld surface topology, historic post-weld surface topology, and/or historic welding process parameters. Thus, the systems and methods described herein may identify weld characteristics for a weld based on the relationships and the pre-weld surface topology, post-weld surface topology, and/or welding process parameters for the weld.Type: ApplicationFiled: April 29, 2022Publication date: August 31, 2023Inventors: Vamshi Kommareddy, Sreekar Karnati, Shivappa Goravar, Brian C.

Patent number: 7586602Abstract: A method of Raman detection for a portable, integrated spectrometer instrument includes directing Raman scattered photons by a sample to an avalanche photodiode (APD), the APD configured to generate an output signal responsive to the intensity of the Raman scattered photons incident thereon. The output signal of the APD is amplified and passed through a discriminator so as to reject at least one or more of amplifier noise and dark noise. A number of discrete output pulses within a set operational range of the discriminator is counted so as to determine a number of photons detected by the APD.Type: GrantFiled: July 24, 2006Date of Patent: September 8, 2009Assignee: General Electric CompanyInventors: Sandip Maity, Ayan Banerjee, Anis Zribi, Stacey Kennerly, Long Que, Glenn Claydon, Shankar Chandrasekaran, Shivappa Goravar
