Abstract
Peculiarities of the reaction of austenitic steel 10Kh13G18D in the form of cold-rolled stock to the thermodeformational cycle of arc welding are considered. The nature of phase transformations in the fusion zone of steel 10Kh13G18D in similar and dissimilar joints with steel 09G2S is shown. Reduction of welding heat input prevents to a considerable degree the metal softening in the fusion zone of welded joints and reduces the probability of precipitation of 8-ferrite in this zone.
Keywords: arc welding, chromium-manganese steel, welded joints, fusion zone, phase transformations, 8-ferrite, softening, welding heat input
