Kenno Tech is a pioneer in designing and manufacturing laser welded, steel sandwich elements.
In co-operation with the Finnish Army we have developed the modular Balpro® Protector fortification system.

Our laser welding line is tailor made for sandwich element production
We posess extensive sandwich structure and laser welding know how – dating back to the “Kenno – Kevyet levyt”-research programme during 1998-2002. We have a partner network providing amongst others demanding structural calculation services.
For sandwich structure design we utilize a purpose-designed sandwich dimensioning software. When required, we will make structural finite element method (FEM) calculations using the MSC FEA-software.
Our laser welding production line uses a 4.5 kW CO2 laser resonator. The sheet thicknesses that we weld through range from 0.3 mm to 6 mm. We weld most steel materials.
The width of our portal is 3 metres, which defines the maximum element width. The maximum length is in practice decided by logistical considerations; so far the longest elements we have manufactured have been some 12 metres long, but technically even longer elements can be produced.
