Common questions about our TIG and SAW welding services for high-nickel superalloys, certification, and inspection.
We weld Inconel 625, 718, 825, Hastelloy C-276, and other high-nickel alloys. Each joint is qualified per ASME Section IX with documented procedure qualification records.
Every weld undergoes ultrasonic phased array testing (PAUT) to detect sub-surface flaws. We provide a full inspection report with time-of-flight and amplitude data, traceable to the joint and welder.
Lead time depends on joint geometry, alloy thickness, and quantity. A standard single-butt weld on 6-inch schedule 80 pipe takes 3–5 business days from material receipt to certified release.
Yes, we can deploy a certified TIG or SAW operator to your facility for field repairs or production support. Travel and setup costs are quoted per project.
Each joint ships with a weld map, PAUT scan report, material traceability certificate, and a signed PQR/WPS reference. All records are archived for at least 10 years.

Why high-nickel fabricators switch to our process
Root pass with TIG for full penetration, fill and cap with submerged arc for deposition rate. No need to switch shops or re-qualify procedures.
All procedures are qualified to Section IX with supporting PQRs. No guesswork when an inspector asks for the paperwork.
Each wire, flux batch, and calibration block is tracked from mill to weld. If a question comes up five years later, the record is still there.
Not just a random sample. Every girth weld is scanned with a 64-element probe and reported with a C-scan map. Defects down to 0.5 mm are flagged.
Inspection reports are issued within 24 hours of weld completion. No waiting a week for NDT results to hold up a shipment.
