| Abstract: | The intrinsic self regulation effect of aluminum alloy wire in the region of short arc in MIG welding is investigated with self made equipment. Melting characteristic of welding wire, the enthalpy of droplet, draptet temperature, and the recovery time constant of arc length are measured. The phenomenon of anode spot climb is verified. It is also pointed out that the intrinsic self regulation effect of wire melting rate exists in case of electrical short circuit. |
