Abstract
This paper describes how the laser cutting process can be
optimised in such a way that the cut sheets can subsequently be
used to laser weld tailored blanks. In a number of systematic
laboratory experiments the effect of cutting speed, assist gas
pressure, average laser power and pulse energy was analysed. For
quality assessment the squareness, roughness and dross attachment
of laser cut blanks were measured. In all tests, the medium
strength steel GA 260 with a thickness of 1.8 mm was used. In this
work it has been successfully demonstrated that the squareness of
a cut can be used as a quality item for parameter optimisation of
laser cut sheets used for tailored blanks. It was concluded that
high quality cut edges with a squareness as small as 0.015 mm may
be obtained. Such edges are well suited for subsequent laser
welding.
