Control over the steel welding structure parameters by micro-jet cooling

The paper presents the characteristics of innovative technology of micro-jet cooling in MIG welding (according to PN-EN ISO 4063:2009). Presented results received at different jet hole geometry and various coolant pressure. This technology allows get, with appropriately selected parameters of cooling increased ferrite AF content in weld metal, up to 14% for standard MIG technology. This structure proves toughness, especially at temperature -40◦C.
