Titel
Welding of aluminium with CO2-laser
Abstract
In industrial production, CO2-lasers have been used in welding steel components for several years. The use of CO2-lasers in deep penetration welding of aluminium alloys was hindered up to now due to the properties of these materials. Due to low absorption, high thermal conductivity and low ionisation energy respectively, the width of variating the process parameters is reduced considerably compared to the welding of steel. Experimental investigations in welding AL 99,5 and aluminium alloys show that it is possible to reach welding results with acceptable and reproducible quality. The presented investigations are an attempt to analyse the difficulties in CO2-laser welding of aluminium systematically.
