Numerical and experimental investigation on the mechanism of synchronous trailing cold air heat sink in eliminating the deformation during laser welding SUS301L thin sheet
TL;DR: In this paper , a synchronous trailing cold air heat sink is used to control welding induced welding deformation of thin stainless steel, which is obtained by using vortex tube compressed air refrigeration (VTCAR), which is safe, low cost and easy to implement compared with other commonly used heat sinks such as argon-water mixture, liquid nitrogen, etc.
