Abstract:

The oxidation behaviour of laser welded of TP347HFG and VM12-SHC stainless steels in air atmosphere were investigated. The temperature was changed from 25 to 1400 C-0. The stainless steels butt were welded. Materials were examined by the thermogravimetric method. The surface and microstructure of the sample were observed in an optical microscope (OM) and a scanning electron microscope (SEM). The X-ray fluorescence spectrometer (XRF) was used to observation change in chemical composition along the cross-section of specimen. The results showed the substantial intermixing of both substrates within the fusion zone. The thermogravimetric data indicate that the investigated materials undergo chemical corrosion. The thermodynamic parameters formation oxides on substrates were calculated and discussed. The CO2 laser welding technique was suggested as a good method for joining dissimilar steels.
