Structure and Properties of Steel Welding after Micro-Jet Cooling Process

Abstract:

Welding with micro-jet cooling is an innovate technology. It is possible to get structure of weld metal deposit (WMD) with a very high amount of acicular ferrite (on the level of 70 %) that is not valuable for other processes. It corresponds with good impact toughness of weld. In the paper parameters of micro-jet cooling and mechanical structure of weld will be present and compared with welding without micro-jet cooling. Results of investigation are very optimistic. That technology should be treated for welding of other materials.
