The research project is focused on an influence of a particullar heat on properties and structure of duplex steel DIN 1.4462. Samples prepared by using different welding speeds 10, 15, 20, 25, 30 cm.min-1, were tested for tensile, metalographical analysis and hardness test. Experimental results proved the optimal welding speed for material with 2 mm thickness to be 15 cm.min-1. Usage of lower speed 10 cm.min-1 led to formation of hot cracks while higher speeds 20, 25, 30 cm.min-1 didn‘t cause material penetration.
