WebView history. Flux-cored arc welding ( FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant- voltage or, less commonly, a constant- current welding power supply. An externally supplied shielding gas is sometimes used, but often the flux ... WebSep 30, 2012 · It is found that good weldability, good mechanical joint properties and acceptable process efficiency can be obtained for thin sheets through advanced power source regulation, especially over short circuiting, controlled polarity and electrode wire motion. The findings presented in this paper are valuable for waveform and deposition …
