ld for the formation of the first spherical end must be treated (with negative electron pressure of the machine into a ball), and the metal surface before welding the preheating; then gold ball at the time and pressure together, the metal welding deformation of the surface of moon, so that the two media to achieve a reliable contact and friction by ultrasonic vibration, the two atomic affinity between the metal atoms the formation of metallic bonds under the effect of realized gold wire welding.
