Abstract: The relationship between droplet transfer and operation performance of self-shielded flux-corded wire (SSFCEW) is studied. Authors think that globular transfer and spray transfer is better transfer mode of SSFCW in six kinds of modes. Although less spatter, more stable arc, short circuit non-explosive transfer, as a main transfer mode of SSFCW is lack of effective protection for droplet. The paper is of magnificent value for guiding formula design and improving operation performance and mechanical properties of SSFCW.
