At the ends of the sample milled groove width of 8 mm and a depth of 2 to 8 mm. The grooves brewing austenitic metal TIG welding on normal mode when heated to 200 ° C. From this part of the sample were made to sand. Metallographic studies showed that fusion occurs at the interface of the metal layer with increased hardness. Cold crack does not occur, but this layer may be the formation of cracks initiated during reactor operation, particularly due to hot cracking and increasing the size of austenite grains in the base metal.
