Certified welders and qualified procedures across six weld processes — from precision TIG to high-deposition submerged arc — spanning carbon steel, stainless, duplex, and exotic alloys.
Fintelius maintains an in-house welding department staffed with AWS-certified welders qualified across a broad range of processes, materials, and joint configurations. Every welding procedure specification (WPS) is developed and qualified in accordance with ASME Section IX, and every welder is individually certified to the specific process, position, and material combination they perform.
From thin-wall precision piping to thick-section pressure vessel plate, our welding capability is matched to the process that produces the strongest, most code-compliant joint — verified by non-destructive and destructive testing on every project.
Every weld on a Fintelius project follows the same disciplined path, regardless of process — qualified, executed, and verified to code.
WPS and PQR development and qualification testing performed in accordance with ASME Section IX.
Welders are performance-qualified to the specific process, position, and material combination required.
Bevel, root gap, and alignment are set to the qualified procedure before any arc is struck.
Process-matched parameters, preheat, and interpass temperature are held within qualified limits throughout welding.
Visual, RT, UT, PT, or MT inspection is applied per code and client specification before weld acceptance.
