Solar Flux is a complex chemical compound in the form of very fine powder. Solar Flux is mixed with alcohol (methanol/methyl alcohol preferred) and brushed on 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 the base metal and form a protective barrier to prevent re-oxidation and heat scale.

Type B is used for stainless steel, (except 309, 310), precipitation hardening steels, chrome-moly steels, other alloy steels with nickel content below 25%. Type B is a cost-effective replacement for Purging

Features: 

Shields the back of the weld joint from oxidization
