Since its start in 2009, United Welding Inc. has focused on and become a leader in the fabrication and field installation of process piping. With its 30,000 square foot facility centrally located in Fredericksburg Virginia, United Welding crews can be found from Richmond to Baltimore.


United Welding is an ASME code shop holding both an ASME "U" stamp and National Board "R" stamp. Our ASME and National Board code designations have allowed us to expand into the manufacturing and repair of metallic pressure vessels. 


Our fabrication shop capablilities include manufacturing of high quality prefabricated process piping, heat exchangers, process skids and custom pressure vessels in a cost effective and timely manner. 


Our primary clients include manufacturers and general contractors in the industrial gas, commerical HVAC, petro chemical, waste water, and water treatment industries. 


Our pipe welders are ASME certified in the 6G position for multiple processes and mulitple alloys. Our ASME certification allows us to maintain the highest quality standards, certifying all welders in house. With this capability, we can cost effectively custom tailor WPS's, PQR's, and WPQ's to fit the needs and budgets of our clients projects. 


With decades of combined experience, the United Welding team looks forward to working with you on your next project.
