Axenics has some of the most experienced TIG and orbital welding staff in the country. Each of our welding staff members is expertly trained and certified to ensure optimal performance. Our technicians perform a variety of custom fabrications for stainless steel and many different types of plastic weldments including: valves, solenoids, pneumatics, piping assemblies and more. Our certified welders are capable of producing high-quality weldments from sizes ranging from ⅛-inch all the way up to 6 inches in diameter.
Experts in High-Purity Welding Services
High-purity welding is used in the semiconductor, medical and aerospace industries to name a few. High-purity welding is done in a cleanroom setting where there is a controlled environment, preventing fewer contaminants from entering the weld area. This is important because the gases or fluids going through the tubing need to remain ultra pure.
Weld quality and integrity are based mainly upon the penetration, oxidation and bead of the weld. A weld is at its strongest when the bead fully penetrates the inner wall of the tubing. A partially penetrated weld is proven to be weaker.
In the industries that demand high-purity welding, like semiconductor and medical, the oxidation of the weld is another solid gauge to the level of weld quality. Dirty welds, or welds with heavy oxidation, lead to contaminants getting into the contents of the system the tubing is servicing. To eliminate dirty welds, the welder purges them with an inert gas on the inside and outside which helps reduce the oxidation levels to make a cleaner weld.
Our technicians’ trained eyes can look at the beading of the welded joint and quickly tell the difference between a good weld and a bad weld. A good weld is exceptionally consistent in both spacing and width throughout the entire weld. If you inspect a bad weld, you will find a wide variation in the bead width and even the length.
