Manufacturing method for producing diamond wire saw by extruding and upsetting electric resistance welding pre-fixed string beads

The invention discloses a manufacturing method for producing a diamond wire saw by extruding and upsetting electric resistance welding pre-fixed beads, which comprises the following steps of: 1, cutting a steel wire rope by a certain length, and extruding and upsetting the steel wire rope on an extruding machine to form small steps; 2, a bead string penetrates through the steel wire rope, the bead string is attached to the small step, and the outer end of the bead string is fixedly connected with the steel wire rope; thirdly, the steel wire rope is placed on the extruding machine, and another small step L is formed through extruding and upsetting of the extruding head; 4, a spring penetrates through the steel wire rope, the spring abuts against the bead string, and another bead string penetrates through the steel wire rope; fifthly, the outer end of the other string of beads is fixedly connected with the steel wire rope, and it is guaranteed that the other string of beads abut against the other small step; si
