Sanitary Welding

FMW welders deliver your Colorado sanitary welding of stainless steel components complete, on-time, and free from defects. In line with this, our welders use a specific process developed and refined in servicing aerospace fabrication and laboratory environments. Our customers use Colorado sanitary welding to ensure high purity throughput, and easy cleaning to eliminate the chance of contamination. As a result, our customers avoid costly situations involving contaminants in stainless steel product transport lines.

AWS D18.1 standard

FMW fabricators weld in conformance to the AWS D18.1 standard for sanitary and sterile welding. Further, the AWS process specification defines he approach for welding on such clean systems. A FMW staff member carefully prepares the surfaces to be joined – this is in conformance with the aforementioned specification. In doing so, the FMW staff follows specific process requirements during welding and post processing operations. FMW staff follows this approach to get a maximum lifetime of service, to ensure that no inclusions or voids are formed, and the inner tube surface is free from defects and contamination.

Domestic Steel

The FMW staff sources and fabricates individual components from highly reliable domestic sources of US-made Stainless Steel. In addition, the FMW staff uses sulfur-free, oil-free cutting fluids to complete machining. Also, FMW Machinists practice proper preparation of weld joint geometry, to ensure proper joining with as little oxidation and distortion of the base material as possible. At that time, the FMW staff degreases parts in a vapor degreaser. The parts are then further cleaned by FMW staff in an ultrasonic detergent-bath cleaner, and rinsed with filtered water. Finally, FMF staff members electro-polish the parts to remove surface material, including embedded contaminants and oxidation. Post cleaning and prior to delivery, FMW staff handles all parts using contaminant free gloves; and the welder completes the welding process in clean/contaminant free environments. FMW staff then bags the parts, and the delivers the parts clean and ready to assemble and leak-test.

FMW welders complete most processes using autogenous welds. This means that FMW welders complete welds without using filler wire. To properly fuse the two elements together with 100% penetration, Welders complete welds using the lowest heat setting possible. In addition, FMW welders pay close attention to seams and joints that do not have 100% penetration. Such a seam or void will slowly release contaminants solvents into the system causing spoilage.
