Physical and Chemical Behavior of Welding Fluxes

Charles A. Natalie, +2 more
- 01 Aug 1986 - 
TL;DR: The welding flux for each of these processes must meet specific physical and chemical requirements to perform properly as discussed by the authors, and the flux viscosity is important because it controls the extent to which the flux can chemically alter the weld-metal composition, and it influences weld metal porosity, bead morphology, and the ability to make out-of-position weld deposits.
