Purpose: of that paper was analysing main plastic properties of welds made by MIG method with micro-jet cooling. The main reason of it was investigate possibilities of getting better plastic properties of welds made by MIG method with micro-jet cooling than welds made by ordinary welding method. It is possible because higher amount of acicular ferrite (AF) in WMD (weld metal deposit) is obtained in MIG method with micro-jet cooling in relation to ordinary welding method. Design/methodology/approach: During research Erichsen cupping tests and bending tests were carried out for welds made by MIG method with micro-jet cooling and ordinary welding method. Findings: High amount of acicular ferrite influences positively on plastic properties. Higher value of plastic parameters were observed for welds made by MIG method with micro-jet cooling. Research limitations/implications: That research was made for MIG method only. Another method of welding was not tested. Other methods of welding have not been tested, but it is suspected that similar phenomena are taking place. Practical implications: MIG method with micro-jet cooling `it is way to get better plastic properties of welds in relation to welds made by ordinary welding method. It is very important because it could be used to steering of mechanical properties of welded constructions. Originality/value: In this research welds made by new method of welding (welding with micro-jet cooling) were compare witch welds made by ordinary welding method. New method of welding is very promising and capable of industrial application, mainly due to the significant improvement of weld properties and quality.
