  Process for plating steel or iron with copper or aluminum.



   The subject matter of the invention is a method to use different base metals by heating and pressure in a simpler way than before.
 EMI1.1
 Heating, which takes place up to the welding temperature of the aluminum, is initially intended to create a pre-connection of the metals to be connected in order to prevent harmful oxidation of the pre-bundle joints when the metals to be connected are subsequently heated to almost their melting temperature. The final connection of the metals does not take place until the second heating.
 EMI1.2
 and puts them in a moderately heated furnace, in which they are heated to around 400 C (welding temperature of the aluminum).



   With this heating, during which the steel does not oxidize, the aluminum has the property of entering into a pre-connection under pressure with the metals to be connected,
 EMI1.3
 The composite piece obtained from the roller is placed in a second, more heated furnace, in which it is heated almost to the melting point of the copper sheet to be plated (zika 900 C) and then rolled out. If aluminum is to be plated on, the composite piece is heated to almost the melting point of the aluminum during the second heating, i.e. i. approx. <00 "('heated.



   In the first oven respectively. the boron compound can have a moderate degree of heating
 EMI1.4
 Iron or steel does not scale yet, only tarnishes. This tarnishing of the iron BEZW. However, steel does not prevent the pre-connection.
