Method for joining parts made of cast change-manganese or manganese steel rails to a rail carbon steel.

摘要

IN A METHOD FOR THE UNION OF SOFT TISSUE (1) AS SHOWN Steel Castings superfirm MANGANESE AUSTENICO, SUCH AS HEART OF NEEDLES OR VIAS manganese steel with a pathway (2) OF CARBON STEEL BY USING A PART INTERMEDIATE austenitic steel POOR IN CARBON WHERE first intermediate piece 3 with the VIA OR WITH VIA CONNECTION (2) WHERE WELDING ACCORDING TO THE cUT OF PART INTERMEDIATE (3) over a length of less WELDING 25 MM. IN THE SECOND WELDING PROCESS PART INTERMEDIATE (3) Part (1) comprising steel casting superfirm VIAS manganese or manganese steel. The adapter (3) GETS STARTING FROM A austenitic LOW CARBON WITH NB AND / OR IT STABILIZED, particularly of steel CR-NI AND HOLDS IN A CONNECTION IN A CONNECTION IN THE TREATMENT OF HEAT FROM A FIRST WELDING UNION, specifically in a diffusion annealing at a temperature of between 350 0 C.
