Whether your project requires TIG (Manual GTAW), fusion orbital welding (Automatic GTAW), wire feed orbital (Semi-Automatic GTAW), stick (SMAW), or MIG welding (GMAW), we are the experts in precision welding solutions.

All of our welders are certified to Section IX of the ASME Boiler and Pressure Vessel Code (B&PV), continually meeting and exceeding a wide array of welding standards. We are well-versed in welding similar and dissimilar metals, both at our fabrication facility and on your project site. We utilize third party welding inspectors. TIG MIG Weld

At HPS, we weld more than just pipe and tube. Many of our customers have called upon us to weld together unique and custom assemblies that range from stainless steel to exotic metal.

Our team excels at producing standard as well as complex pipe and tube spool configurations. From extremely small connections with challenging weld angles, to large spools that require our extensive knowledge to overcome material deformation from the various weld locations. We’ve been asked to do it all, and delivered every time.

We regularly provide orbital welding services to produce extremely intricate skidded systems for use in the aerospace, chemical, agriculture, and oil and gas industries. We fabricated and delivered 14 ground support equipment stainless steel skids to the NASA Wallops Island Flight Facility in support of the ongoing satellite and International Space Station support missions where we then installed the ground support skids and the interconnecting piping onsite. These unique welding challenges and required level of precision and detail are where the HPS team’s expertise shines.

The High Purity Systems team has developed 7 patents that give the welder and the weld inspector tools to enhance the overall quality of the welded system.

These patented tools include:micron-gas-panels-12

  • A back purge instrument that closely monitors and regulates the ID inert gas purge pressure during welding to create the most consistent and repeatable weld no matter how small the diameter.
  • A “Go/No-Go” weld profile tool that removes interpretation of the welding specification and gives the welder and the weld inspector a tool to measure to the final weld parameters per the actual welding spec. Many times we’ve encountered situations where the welder and the inspector each interpret the orbital welding requirements differently. This weld profile tool is a game-changer for taking individual interpretation out of weld inspections!

These proprietary tools are put to use daily in our certified Class 100/Class 1000 Clean Room where we specialize in producing welded solutions for the semiconductor, aerospace, and biopharmaceutical industries. Our in-house clean room allows us to offer the double bagging services required for the most stringent clean room welding applications our customers require. We also have extensive experience in delivering comprehensive weld documentation packages for FDA required validation/turnover packages and NASA required documentation for aerospace projects.

Whether you need to orbital weld a 1/16” OD tube or MIG weld a 42” diameter pipe for a waste water treatment plant, the High Purity Systems team is ready to review your CAD drawing or prints and get to work on your one-off prototype or high volume production run. Don’t have a drawing? No problem, we can assist with that too. See samples of our work here and review our complete list of welding capabilities below.
