In the article the results of research of connections of details are resulted from steel of 40kh, soldered a copper in hydrochloric baths and in a vacuum, and also connections, soldered in hydrochloric baths after heat treatment in hydrochloric baths and in chamber stoves. It is set as a result of the conducted work, that process of soldering in hydrochloric baths and in electro-thermal vacuum stoves accompanied mutual mass is a transfer of components 40kh and copper solder became. Thus components became 40kh alloy a copper solder, that increases durability of the soldered connection, and heat treatment on diffusive mass is a transfer renders insignificant influence.
the soldered connection, modes of soldering, modes of heat treatment
