DETACHABILITY OF SLAG CRUST IN ARC WELDING (Review) Part 2. Character of the effect of main factors on detachability of slag crust

Abstract
The effect of various particular factors on detachability of slag crust in automatic arc welding is analysed. It has been established that the flux being developed for narrow-gap automatic arc welding of thick joints should ensure formation of the slag crust with the minimum possible strength and maximum possible linear thermal expansion coefficient. Brief characterisation of the currently available methods for experimental evaluation of detachability of the slag crust is given.
