Abstract

Steps of discernment and evaluation by hearing acuity of welding arc sound are systematically discribed along with results and, continued from the preceding report, several characteristics including noisy characteristics of the arc sound are reviewed. The hearing acuity shows good discerning function ; Thus, translating form of droplet and stability of the arc can be discerned by the arc sound ; however, in cases of high current arc welding, pulsed arc welding or the like, hearing protective device against noise of the arc sound is sometimes required. Further, among frequency bandwidth of the welding arc sound, bandwidth 707-2245Hz is a remarkable one wherein such informations as arc voltage, shielding effect, electrode extension and others can be obtained.
