Welding process null of dissimilar metal

摘要

PURPOSE: To provide excellent quality welding between a high melting point metallic material and a low melting point terminal when they cannot be welded together by means of clamping by both electrodes. ;CONSTITUTION: A recessed part 4 is provided in a non-conductive holder 2. A thin cap 1b, which is provided in a high melting point metallic material sensor case 1, is stored in the recessed part 4, three or more of projections 5 are arranged in a low melting point terminal 3 so as to touch a chassis 1, the low melting point terminal 3 and the chassis 1 are brought into contact with a positive electrode 6 and a negative electrode 7 individually, and consequently, resistance welding is carried out.;COPYRIGHT: (C)1994,JPO
