Abstract

Two point-by-point femtosecond FBG arrays have been realized in order to monitor a TIG welding on a stainless steel plate. In this paper, we demonstrate the ability for femtosecond FBG to withstand and monitor strain and temperature during a metal welding process with transient temperature up to 900°C and 2 % compressive strains.
