GTAW / TIG welding
CORE DISCIPLINE

GTAW / TIG Welding

The clean, slag-free fusion process aerospace pioneered. Trusted on commercial and military aircraft for over 30 years, certified to AWS D17.1.

Micro TIG welding under microscope
EST. 1999

Micro TIG Welding

GTAW performed under a microscope with filler wire as fine as 0.005 in, joining aircraft parts as thin as 0.016 in.

Orbital tube welding
EST. 2006

Orbital Tube Welding

Machine-performed GTAW producing repeatable, radiograph-grade welds on aircraft hydraulic lines. Boeing BAC 5974 approved, 3/8 in to 1/2 in OD stainless.

STRESS RELIEF

Heat-treated under
our own roof.

Pre- and post-weld thermal treatment never leaves the building. Our calibrated Baker furnace relieves residual stress and locks in dimensional stability before a part ever ships, on a Nadcap-approved process.

THE DCWI STANDARD — FROM SPECIFICATION TO FLIGHT
01

Engineering & Planning

Every program begins with rigorous technical review. Engineering drawings, customer requirements, and AWS D17.1 specifications are analyzed, approved, and controlled before production begins, ensuring compliance from the very first operation.

Fixturing & Atmosphere Control

Precision starts long before the arc is struck. Components are expertly fixtured and protected with controlled inert gas purging to eliminate contamination and preserve material integrity throughout the welding process.

Flight Critical Welding

Certified aerospace welders execute mission-critical welds on titanium, Inconel, stainless, aluminum, and specialty alloys with uncompromising precision. Every weld is fully traceable to the operator, process, and material lot, delivering complete accountability.

Verification & Certification

Quality is validated, not assumed. Post-weld non-destructive testing (NDT), dimensional verification, and required stress-relief processes confirm every component meets the zero-defect expectations of the aerospace industry.

Documentation & Delivery

Every shipment leaves DCWI with complete certification packages, material traceability, and inspection records, giving customers confidence that every part is ready for its next mission.
