Product Overview
In high-purity environments, the weld is often the most vulnerable point of the system. Our Hygienic Filler Metals are manufactured with strictly controlled chemistry and extreme surface cleanliness to ensure that every joint meets the rigorous standards of aseptic processing.
Aseptic Weld Quality
The primary goal of hygienic welding is to create a “flush” internal bead that is as smooth as the parent tube. Our welding wire is engineered for high fluiditiy and excellent wetting action, which allows the welder to achieve a flat, uniform root pass. This is vital for Clean-in-Place (CIP) systems, as it eliminates crevices where organic matter could otherwise accumulate.

Low Carbon for Corrosion Resistance
We exclusively provide “L” Grade (Low Carbon) wire. By keeping carbon levels below 0.03%, our filler metal prevents the formation of chromium carbides during the welding process. This ensures that the weld remains fully resistant to intergranular corrosion—a necessity when the piping is subjected to the aggressive acids and high-temperature steam used in Steam-in-Place (SIP) cycles.
Surface Purity
Our TIG rods and MIG wires undergo a specialized cleaning process to remove all traces of drawing lubricants and surface oxides. This prevents the formation of “black spots” or porosity within the weld pool, ensuring the finished joint passes strict radiographic or dye-penetrant inspections required in pharmaceutical and food-grade installations.
