The Effect Of Different Micro-Jet Streams Number On Plastic Properties Of Welds

Open access

Abstract

The main goal of that paper was analysing of plastic properties of welds made with micro-jet cooling. New technology of micro-jet welding could be regarded as a new way to improve plastic properties of welds. It allows to obtain welds with better properties in comparison to ordinary welding method. Moreover, it is possible to steering of weld structure and properties of the weld. During research Erichsen cupping tests and bending tests were carried out for welds made by MIG method with micro-jet cooling. Argon was cooling medium. Different numbers of micro-jet streams were used to weld cooling. Different plastic properties were obtained for different numbers of micro-jet streams. In this research welds made by new method of welding (welding with micro-jet cooling) were compared with welds made by ordinary welding method.
