Higher order spectral analysis of acoustical signals of welding process

Marek Fidali

Abstrakt


The article presents results of research on the application of third-order spectrum to analysis of the acoustic signal of welding proces. Higher spectrum in contrast to the commonly used power spectrum retain dependency information phase and allow you to fully characterize the instability of the welding process which is confirmed by studies carried out.

Analiza widmowa wyższych rzędów akustycznych sygnałów procesu spawania

W artykule zaprezentowano wyniki badań nad zastosowaniem widma trzeciego rzędu do analizy sygnałów akustycznych generowanych w trakcie spawania. Widma wyższych rzędów w przeciwieństwie do powszechnie stosowanego widma mocy sygnału zachowują informację o zależnościach fazowych i pozwalają w pełni scharakteryzować niestabilności procesu spawania, co potwierdzają przeprowadzone badania.
