Name ThicknessCommentsProduction SMAWShielded Metal Arc Welding (stick) 0.06-0.75 inFlexible, portable, requires skilled operator (ASME certification for pressure vessels)) Low Capital Cost High Labor Cost Good for Repair and low quantity SAWSumberged Arc WeldingUsually thick >0.18 in More automated version of arc welding 4-10 times as fast as Stick welding. Higher Capital, lower labor cost High quantity FCAWFlux Cored Arc WeldingSimilar to SAW 0.060-16.0 in Automated, higher powerMedium to high quantity. Higher capital cost.
