NANOCHEM® WeldAssure™ purifiers provide purge and shield gas purification for welding applications. Weld gas impurities, such as moisture and oxygen, adversely affect weld quality. These impurities are present in gas cylinders, and can also be introduced through leaks in the line or during cylinder changes. NANOCHEM® OMX™ and In2Go™ media react chemically and irreversibly with these impurities to deliver consistently pure gas to the weld site, improving weld quality. NANOCHEM® OMX™ resin also offers efficient removal of hydrocarbons, such as compressor oils, in the gas. A new inorganic media, NANOCHEM® In2Go™ prevents piping system contamination in the event of a major system upset, such as significant air intrusion or from the accidental connection of an improper cylinder to the purifier.

Features and Benefits

• Low cost of ownership
• Wall mount frame – easy to install and operate
• Removes impurities to < 10 ppb (Dew Point = -150ºF)
• Enhances weld quality, strength and appearance
• Reduces weld porosity and oxidation
• Visual endpoint detection*
  – No guessing when to replace purifier canister
  – Color change in viewing window indicates 80% of
purifier is spent
• Increases weld electrode lifetime
  – No need to stop welding to grind/replace electrode
• Reduces weld rejects
• Built-in Bypass around purifier canister
  – Enables purging of gas lines without purifier
deactivation during cylinder changeout
• Check valve at purifier outlet
  – Prevents purifier deactivation from back diffusion of
atmospheric air when gas flow is stopped
• Filters at canister inlet and outlet
• Operates at room temperature
• No power requirements
• Flow rates up to 100 cfh (47 slpm / 2.8 NM3/hr) 

Applications

GTAW (TIG), GMAW (MIG), PAW (Plasma) and LBW (Laser Beam) welding applications and welding overlays with GMAW and PTAW (Plasma Transferred Arc). Aerospace, nuclear, petrochemical, pharmaceutical, petroleum drilling, ship-building, and other manufacturing industries.
