Abstract

This paper reports the results obtained by using a measuring system concerned automatically residual stress by Hole- Drilling Strain Gage Method, in depth, on thin stainless steel sandwich structural panels all laser welded. Different corrugated cores, core geometries (usually trapezoidal ones), face thickness, welding parameters and methodologies (spot or continuous ones) have been carried out.
