The welding process stability is a critical factor regarding the quality of the manufactured products in the Industry. There are two approaches to assess the metal transfer stability based on droplet transfer period: scanning arc voltage or scanning wire feed speed. Studies based on each of the approaches can be found in current literature, but there are no reported studies evaluating the role of the arc reignition voltage peak (RiVP) on stability. Thus, this paper aimed to propose a novel method to assess the short-circuiting gas metal arc welding metal transfer stability based on arc reignition voltage peak distribution, via wire feed speed scanning route, and compare the effectiveness of the proposed method to the existing ones. First, the authors depicted the fundamentals of the ideal metal transfer (the most stable). A novel stability index based on the RiVP distribution was introduced. The results showed that the methodology was capable of defining a locus of maximum metal transfer stability through the arc RiVP regularity. It also demonstrated that, in a regular short-circuiting transfer mode, the RiVP obeys an expected distribution. Besides, the most regular arc reignition-related quantity was directly related to the most regular period-related characteristic. After validating the methodology, the proposed method was demonstrated to be, potentially, a novel manner to assess and seek the maximum stability of the short-circuiting gas metal arc welding process.
