Abstract

Laser welding of stainless steel AISI 304 and AISI 405 is investigated. Laser source with "flat-top" energy distribution is employed which produces welded joints with similar geometry to other conventional welding techniques. Mechanical properties of the welds are however very similar to those typical of deep penetration processes. Microhardness and bend tests as well as micrograph examinations have been carried out on the welds. The test pieces exhibited good mechanical strength and in particular acceptable ductility. Theoretical considerations based on widely accepted thermal models have also confirmed that the process proceeds at high efficiency energy transfer.
