Resistance welding method of different types of materials, and the resistor sweat component made of an aluminum alloy material and a different material

摘要

Resistance welding method for welding of an iron material (10) with an aluminum alloy material (1) with the formation of a sweat lumps (n), wherein, prior to the resistance welding at least one section of the aluminum alloy material (1), where the resistance welding process is to take place, with an iron-based alloy for the formation of a surface layer (2, 3) is treated,characterized in thatthe aluminum alloy material (1) on both sides with the surface layer (2, 3) is provided, and in that during the welding of the perspiration lumps (n) up to the from the iron material (10) remote surface layer (3) of the aluminum alloy material (1) and extends from this surface layer (3) is concealed,that the thickness of each surface layer (2, 3) in a range from 0,01 to 40 μm is,that the surface layer (2, 3) 82% to 98% fe and the radical contains cr, andthat it comprises an electrode (e1), which is remote from the iron material (10) is in contact with surface layer (3), from a chromium-containing cu - alloy.
