Unlocking some of the Mystery in Submerged Arc Flux Selection
• Basic Process
• The number of process variations adds to the complexity of choices.
• Process variation
• Three basic criteria for flux selection:
o Application requirements
o Weld performance
o Mechanical properties
• AWS Classifications for carbon steel – What the numbers mean:
• Flux manufacturing
• Active vs neutral flux
• Acid vs Basic
• General Maintenance:
o Weld metal hydrogen and cracking
o Flux storage – temperature and humidity
o Recycling flux – flux break-down issues
o Recrushed flux – certification of material, performance
• Stainless fluxes
o Neutral, chrome compensating, Chrome enhancing
o Ferrite numbers and cracking
