Solar Flux Type B
Solar flux is a complex chemical compound, in the form of a powder finer than talcum powder. After welding it is important to seal and protect the back of the weld. Failure to treat the back of the weld will result in a porous, sugary weld that may lead to burn-through.
There are a variety of solar flux formulations available for welding different metals. Solar Flux Type B is specially formulated for welding stainless steel and alloy steels. When correctly mixed with alcohol (preferably methanol) and brushed on the back of the weld joint, Solar Flux forms a shield, protecting the weld from Oxygen. Dissipating the heat and unwanted oxides leaves you with an x-ray quality weld. It works to clean the metal, aiding of the flow of the filler metal over the base metal. By doing this, a protective barrier is formed that will prevent heat scale and re-oxidation.
It offers many benefits over the alternative sealing method of purging. Purging a weld usually requires an inert gas, such as argon. While this gives a similar finish solar flux is significantly easier and cheaper source. It is also faster and considerably easier to use.
- Type B for welding Stainless Steel and Alloy Steels Solar Flux
- Type I for welding High Nickel Super Alloys
- Type B conforms to the requirements of the US Military Specification MIL-F-7516B, Classes 2 and 4
- Type I Conforms to the requirements of the US Military Specification MIL-F- 7516B, Classes 1, 2, 3 and 4
Solar Flux is ideal for use on pipe and tube welding, maintenance welding, in-field welding, one of a kind welds…and many, many more. If you would like any information regarding Solar Flux please get in touch.
