What is solar flux

Providing welders with the means of making x-ray quality welds on stainless steel and high nickel alloys for over 70 years.

SOLAR FLUX is a complex chemical compound in the form of a very fine powder—finer even than a lady’s face powder. SOLAR FLUX is mixed with alcohol (methanol/methyl alcohol preferred) and brushed on the back of the weld joint. It is formulated to shield the BACK of the weld joint from oxygen, dissipate heat and unwanted oxides, and to clean the surface of the metal. It will aid in the flow of filler metal over base metal and form a protective barrier to prevent re-oxidation and heat scale.

Types of SOLAR FLUX:

  • Type B for welding Stainless Steel and Alloy Steels
  • Type I for welding High Nickel Super Alloys

Some of the Common Applications for SOLAR FLUX:

  • Pipe and tube welding (except in those few cases where removal of the thin, glass-like residue is required)
  • Maintenance welding
  • In-field welding
  • One-of-a-kind welds
  • Unusual shapes and configurations
  • Large diameter pipes and ducts
  • Certain specified aircraft airframe and jet engine repairs
  • ……. and many, many more!
