Control of Softening Processes in the Heat-Affected Zone During Welding of High-Strength Steels

Efimenko, L. A. Kapustin, O. E. Ramus’, A. A. Ramus’, R. O.

Published in Metal Science and Heat Treatment

The hardness and the structure of the heat-affected zone (HAZ) under welding of tube steels of strength category K60 – K70 are studied. The steels are treated by regimes imitating the thermal cycles of different welding processes applied to tubes starting with manual arc welding and ending with energy-intensive automatic submerged-arc welding. The ...

On the decomposition of austenite in the heat-affected zone upon welding of high-strength steels

Efimenko, L. A. Ramus’, A. A. Merkulova, A. O.

Published in The Physics of Metals and Metallography

The kinetics of the decomposition of austenite in the heat-affected zone of welded joints of low-carbon microalloyed high-strength steels has been investigated. A new approach to selecting the parameters of the thermal cycle of welding that ensure the service characteristics of welded joints on a level no lower than the normative requirements is su...
