Abstract

This paper presents results of experimental research concerning the impact of an innovative method of micro-jet cooling on the padding

weld performed with MIG welding. Micro-jet cooling is a novel method patented in 2011. It enables to steer the parameters of weld

cooling in a precise manner. In addition, various elements which may e.g. enhance hardness or alter tribological properties can be entered

into its top surface, depending on the applied cooling gas. The material under study was steel 20MnCr5, which was subject to the welding

process with micro-jet cooling and without cooling. Nitrogen was used as a cooling gas. The main parameter of weld assessment was wear

intensity. The tests were conducted in a tribological pin-on-disc type position. The following results exhibit growth at approximately 5% in

wear resistance of padding welds with micro-jet cooling.
