SOLAR Flux® Type B Powder Welding Flux

SOLAR FLUX® Type B – Powder Welding Flux

A specialised powder flux designed for welding stainless and alloy steels when back-purging isn’t practical. Solar Flux Type B protects the backside of the weld from oxidation, improves weld quality, and helps create smooth, clean joints.

Key Features

• Powder flux that mixes with alcohol and brushes onto the joint

• Prevents oxidation on the back of the weld

• Helps filler metal flow smoothly and evenly

• Reduces need for full argon purging setups

• Extremely stable product with an unlimited shelf life if kept dry

• Non-hygroscopic and non-explosive

Technical Specifications

• Brand: Solar Flux®

• Type: Type B Powder Welding Flux

• Application Range: Approx. 1093°C – 1593°C

• Compatible Metals: Most stainless steels, chrome-moly steels, and alloy steels with nickel content below about 25%

• Mixing: Combine powder with methanol or suitable alcohol, brush onto joint

• Compliance: Meets MIL-F-7516B standards

Applications

• Stainless steel pipe and tube welding

• Fabrication where back-purging is difficult

• Exhaust systems, headers, tanks, and stainless components

• Repair work on stainless assemblies

• Anywhere backside oxidation needs to be controlled without full purging gear

Why Fabricators Use It

Solar Flux Type B blocks oxygen, reduces oxide build-up, and prevents sugaring — giving cleaner welds and stronger penetration without needing purge dams or argon back-purge setups.
