This disclosure provides a joining area and method between copper and stainless steel or titanium, as well as the permanent cathode obtained, where said joining area is made of a first zone of a copper-nickel (Cu—Ni) alloy, an intermediate zone with a mostly nickel alloy or pure nickel and a second zone made of a stainless steel-nickel alloy, which is the result of the participating materials being cast in an arc welding process, for example TIG, MIG or manual arc using electrodes of nickel as welding contributor between said materials and their space arrangement, that is to say, leaving a separation between the materials when performing the welding process, thus ensuring as follows: a) greater tensile strength, b) a substantial improvement of corrosion resistance of the joint welding, and c) improvement of conductibility, which can be improved still further by modifying the straight design of the conducting bar by providing it with the “horn”-type shape.
A corrosion resisting joining area between copper and stainless steel or titanium which are the constituents of permanent cathodes for electrolytic processes wherein it is made by a first zone formed of a copper-nickel alloy (Cu—Ni), an intermediate zone of mostly nickel and a second zone made of a stainless steel-nickel allow which is the result of the participating materials becoming cast in a process of voltaic arc welding of the TIG, MIG type or manual arc welding process using pure nickel electrodes as contributing welding between said copper materials and a stainless steel material.
Permanent cathodes for electrolytic processes with corrosion resisting joining areas between the copper and stainless steel or titanium wherein it comprises a conducting bar, a stainless steel or titanium plate and a joining area made by a first zone formed of a copper-nickel alloy (Cu—Ni), an intermediate zone with a mostly nickel alloy and a second zone made of a stainless steel-nickel allow which is the result of the participating materials becoming cast in the voltaic arc welding process of the TIG, MIG type or manual arc welding process using pure nickel electrodes as contributing welding between said copper materials and a stainless steel material.
