Abstract
Abstract The present invention is a honeycomb panel comprising metal face sheets respectively disposed on upper and lower faces of said honeycomb core characterized in that said honeycomb panel has a metal side plate disposed on at least one side face thereof, for mutually connecting honeycomb panels to each other, and a process for producing a honeycomb panel, said process characterized by comprising the steps of: welding a corrugated honeycomb core at an end face of its corrugation to a side plate along the end face of said corrugation; welding the honeycomb core at top portions of its corrugation to an upper face sheet from the side of the honeycomb core by means of an energy beam; welding bottom portions of the corrugation of the honeycomb core to a lower face sheet from the side of the face sheet by means of an energy beam; and welding the face sheets to the side plate before or after welding the honeycomb core to the face sheets.

Claim 1
Independent Claim
176 words
A process for producing a honeycomb panel, including a corrugated honeycomb core formed from a sheet having a thickness, said process comprising the following sequence of steps: 1) providing a side plate with a groove having a wider width than the honeycomb core sheet thickness for fitting an end face of the corrugated honeycomb core, 2) filling up with a metal filler a clearance gap between the groove of said side plate, 3) fitting the honeycomb core and side plate into each other 4) laser beam welding along fitting portions from the side of the core, and then laser beam welding the side plate and the core to each other, 5) laser beam welding the core at top portions of corrugations of the core to an upper face sheet from the side of the core, 6) laser beam welding at bottom portions of corrugations of the core to a lower face sheet from the side of the lower face sheet, 7) and laser beam welding the side plate to the upper and the lower face sheets.
