The invention provides a resistance wire and high-temperature wire spot welding butt joint process which comprises the following steps: (1) preparing a resistance wire, a metal sleeve and a high-temperature wire with a stripped wire head, wherein the stripped wire head is slightly longer than the metal sleeve; (2) bending the joint end of the resistance wire, and sleeving the joint end by the metal sleeve, wherein the part, sleeved by the metal sleeve, of the joint end is longer than the metal sleeve; (3) threading one end of a stripped wire head of the high-temperature wire into the metal sleeve, wherein the wire head extends out of the metal sleeve, and flattening the metal sleeve by using a wire pressing clamp, so that the high-temperature wire is in close contact with the resistance wire; (4) welding the surface of the metal sleeve by use of a spot welding machine, so that the connection of the resistance wire and the high-temperature wire is firmer; and (5) finishing the spot welding, and finishing the s
